The United Nations Convention on Contractsfor the International Saleof Goods
body of national law for certain international sales transactions. It
also provides a common basis for interpreting contract provisions,
and it provides substantive law for filling the gaps left by contract
drafters.7 In addition, the CISG addresses the choice of law prob-
lems that vex drafters of international sales contracts. 8
Thesuccessof this effort is as yet unclear. There is no international5
court with jurisdiction over disputes arising in trade that would be
addressed by the treaty. Rather, the treaty is adopted by positive
authority as the internal trade law of each signatory nation, to be
applied and interpreted by the judiciary of each nation.9 Thus, the
treaty must be used to resolve conflict before one knows whether
unification has been achieved or uncertainty reduced. The treaty
has been adopted by countries with substantially different tradi-
tions of procedure and legal authority.10 The success of the treaty,
therefore, will depend upon the extent to which ambiguities will be
resolved in a common manner. This will depend, in turn, on the
willingness of the national courts of each signatory nation to draw
on other signatory nations' judicial experience with the
treaty, as well as their willingness to recognize the multilateral na-6
ture of the treaty and the desirability of harmonized interpreta-

It is possible, nevertheless, to identify the potential areas of 7
ambiguity and uncertainty, based on the American experience 8
with construction of the Uniform Commercial Code (UCC). Like
the UCC, the CISG was designed to harmonize the trade law ofseparate legal jurisdictions. Although international trade prac-
tices differ significantly from interstate trade practices, the basic
dynamic of selling and shipping goods from one place to another
-- whether in international or interstate trade -- poses certain
common and inherent problems. These problems include: 1) How
is a contract formed? 2) Who bears the risk of loss of the goods
at various points in the transaction? 3) What kind of performance
is necessary to trigger the party's obligation to perform? 4) What
remedies are available for a buyer who receives defective goods?
To a great extent, trade practice turns on the expected legal
resolution of these fundamental issues. It is possible, however, toidentify the areas of likely conflict under the CISG by analogy to
the resolution of conflicts under the UCC.
This paper provides a descriptive analysis of the most significant 9
aspects of the CISG, with particular attention to those ambiguities
most likely to defeat the Convention's goal of providing certainty
and uniformity in trade law. The paper first explains the coverage
of the CISG and the scope of its use in international sales trans-
actions. The paper then identifies four areas of potential conflict
between buyersand sellers of goods in international trade andana-

of good faith in international trade. See Patterson,supranote 2, at 277, citing
with approval the United States Supreme Court opinion in Air France v. Saks,

words of the treaty a meaning consistent with the shared expectations of the
contracting parties.);See generally, 1 K. Zweigert and H. Kotz, An Introduction
to Comparative Law 22-23 (1987) [hereinafter Zweigert and Kotz].

The United Nations Convention on Contractsfor the International Saleof Goods
lyzes the manner in which these areas are addressed by the CISG.
The analysis draws on experience under the UCC and speculates
on the potential similarities and differences in resolution of the con-
flicts under the CISG. The four areas are: 1) formation of the con-
tract; 2) risk of loss; 3) performance; and 4) remedies. The goal
of this analysis is to inform the negotiating and decision processin sales transactions and to illuminate underlying premises of the
CISG's approach to transactions.
II. The Scope and Coverage of the COnvention10
The CISG is a self-executing treaty; its provisions become effective11
as a source of legal rights without need of implementing domestic
legislation.12 In the United States, federal treaties preempt incon-
sistent state law.13 Thus, for the American lawyer, the first salient
question of scope and coverage is whether the CISG displaces the
state UCC law in a given transaction.
Article 1 of the CISG provides that the Convention applies to con-12
tracts between parties whose places of business are in different
States: (a) when the States are Contracting States; or (b) when
the rules of private international law lead to the application of the
law of a Contracting State.14 Under Article 6, however, the parties
may exclude the application of this Convention or . . . derogate
from or vary the effect of any of its provisions.15 Thus, the par-
ties have the capacity to modify by contract the application of the
CISG.
A further complication of scope and coverage lies in the fact that13
12CISG,supranote 1, art. 99. Self-executing treaties require no further federal
legislation to be effective throughout the United States. See Patterson,supra
note 2, at 276; Volken and Sarcevic, supranote 1, at 21.13U.S. Const. art. VI; Zschernig v. Miller, 389 U.S. 429 (1968).14CISG,supranote 1, art. 1. See Honnold,supranote 1, at 77-84.15CISG,supranote 1, art. 6.
the CISG applies only as to issues expressly covered by the Con-
vention. As to issues not covered by the CISG, states must revert
to their choice of law rules to find applicable substantive law. 16 Un-
der the UCC, an American court seeking such law would look to its
version of UCC 1-105, which states:
Except as provided hereafter in this section, when a transac- 14
tion bears a reasonable relation to this state and also to an-
other state or nation, the parties may agree that the law either
of this state or of such other state or nation shall govern their
rights and duties. Failing such agreement this Act applies to
transactions bearing an appropriate relation to this State.17
Where the parties to the contract have specified the applicable for- 15
eign law, American courts have scrutinized the contractual choice
of law provision for some nexus between the transaction and the
law identified in the contract.18 Where the contract is silent as to
choice of law, the appropriate relation test may be invoked. In adomestic commercial sales transaction context, this provision has
had limited significance, since the UCC is universally, if not uni-
formly, adopted within the United States.19 In the context of a
transaction covered by the CISG, but unaddressed by the CISG,
the appropriate relation test may emerge as a significant choice
of law provision.20 Both the CISG and the UCC may apply to a dis-
16In addition, the courts of signatory states to the CISG may look to the Hague
Convention on the Law Applicable to Contract for the International Sale of
Goods (Choice of Law Convention), which provides courts in signatory states
with rules for determining the law applicable to sales contracts between parties
from different states. However, the areas covered by the Choice of LawConvention are, for the most part, those covered by the CISG.

pute arising out of an international sales transaction in an American
court.
TheCISG governs only theformation of thecontract of sale andthe16
rights and obligations of the seller and the buyer arising from such
a contract.21 In fact, the CISG does not cover several common
issues of sales law that are covered under the UCC. For example,
CISG Article 4(a) specifically excludes from coverage the validity
of the contract or of any of its provisions or of any usage. 22 Article
5 excludes application of theConvention to the liability of the seller
for death or personal injury caused by the goods by any person.23
In addition, theCISG is silentas to liability forcommercial fraud and
capacity of the contracting party. In addition, Article 7(2) provides
that: Questions concerning matters governed by this Convention
which are not expressly settled in it are to be settled in conformity
with the general principles on which it is based or, in the absence
of such principles, in conformity with the law applicable by virtue of
the rules of private international law.24
Since the CISG supplies substantive law only in the area where17
the UCC, or other local law, is displaced, the Convention does not
eliminate the incentive to forum shop.25 To identify the relative
advantage of forums, it is useful to review the substantive areas of
law covered by the CISG.
In general, the CISG does not apply to sales of goods bought for18
consumption by the buyer, unless the seller did not know that the

formation of the contract. Part III covers the substantive obligations of the buyer
and seller. Part IV concerns ratification of the treaty.22CISG,supranote 1, art. 4(a).23Id. art. 5.24CISG,supranote 1, art. 7.25SeeRohwer and Coe, supranote 8, at 225.
buyer intended the goods for consumer use.26 It also does not
apply to the sales of securities, negotiable instruments or money27
or to the sale of ships, aircraft or electricity.28 It also does not apply
to contracts for the sale of future goods not to be manufactured
by the seller, or to contracts where the preponderant part of the
obligation consists of the supply of labor or services.29
The CISG does apply to other contracts of sale of goods between 19
parties whose places of business are in different states, when the
states are Contracting States.30 An exception is carved out where
it does not appear from the contract or from dealing between the
parties before the conclusion of the contract that their parties have
their places of business in different states.31 Two criteria must
be met for the Convention to apply automatically: the places of
business of the contracting parties must be in different states, and
those states must be Contracting States. So, for example, if a
non-American party has a place of business in a non-Contracting
State, the CISG will not apply, and the UCC or the domestic law ofthe non-Contracting State will apply. If the non-American contract-

The United Nations Convention on Contractsfor the International Saleof Goods
the Soviet Union sought to preserve the requirement of a writing,
which that country regards as necessary to protect its domestic
rules for making foreign trade contracts. Thus, the Soviet Union
may exercise rights under Article 96 to opt out of Article 11 and
impose formal requirements for international sales contracts. The
United States has not done so.
B. Approach to Offer and Acceptance25
In contrast to the UCC, the CISG takes a relatively formal view26
of contract formation. Under the UCC, a contract for the sale of
goods may be made in any manner sufficient to show agreement,
so long as the parties have intended to make a contract and there
is a reasonably certain basis for giving an appropriate remedy. 42
Intent, of course, can be a source of legal controversy. Under Ar-
ticle 8 of the CISG, intent is determined from an objective analysisof what a reasonable person would have intended, given the rel-
evant circumstances, the course of dealing, trade usage and the
subsequent conduct of the party. The functional approach to con-
tract -- of givinglegal recognition to a transaction that appears to be
regarded by the parties as a contract, without need of formal anal-
ysis of offer and acceptance -- characterizes the UCC. The CISG,
in contrast, adopts a more formal analysis of contracting behavior,
manufactured for the buyer and are not suitable for sale to others, and the seller
has made a substantial beginning of their manufacture or commitments for their
procurement, U.C.C. ?2-201(3)(a); the party against whom the contract is to be
enforced has admitted in pleadings, testimony or otherwise in court proceedingsthat a contract exists, U.C.C. ? 2-201(3)(b); or payment has been made and
accepted or goods have been received and accepted, U.C.C. ?2-201.42U.C.C. ? 2-204 (1978). This language is broad, authorizing courts to weigh
and balance a wide variety of facts which might be relevant in showing
`agreement'.See Note,supranote 5, at 532; Sono, Formation of International
Contracts Under the Vienna Convention: A Shift Above the Comparative Law, in
Volken and Sarcevic, supranote 1, at 111.
and is reminiscent of the First Restatement of Contracts approach
to contract analysis.43
Under the CISG an offer must be addressed to a definite person 27
and it must be sufficiently definite and indicate the intention of the
offeror to be bound in case of acceptance.44 To meet the suffi-
ciently definite test, the offer must indicate the goods and also ei-
ther fix the quantity and price or explicitly or implicitly provide for
determining the quantity and price.45 This language is only slightly
narrower than that of UCC 2-204(3), which permits open and in-
definite terms, subject to the requirement that the court have a rea-
sonably certain basis for giving a remedy.46 Presumably, under the
43Restatement of Contracts ?? 19-74. Note, for example, the similarity with the
Restatement in the approach taken in article 23 of the CISG: A contract is
concluded at the moment when an acceptance of an offer becomes effective in
accordance with the provisions of this Convention. See generally,Farnsworth,
Contracts During the Half-Century Between Restatements, 30 Clev. St. L. Rev.
371 (1981); Note,supranote 5, at 533 (The Convention's offer-and-acceptance
formality is mitigated, fortunately, by provisions which make practices between
the parties and trade usages relevant in the determination of the parties' intent
to enter into a contract.).44CISG,supranote 1, art. 14. Subsection 8(3) of article 8 provides that due
consideration is to be given to all relevant circumstances of the case including
the negotiations, any practices which the parties have established between the
negotiations, any practices which the parties have established between
themselves, usages and any subsequent conduct of the parties. In addition,
article 9 explicitly permits the parties to agree upon usages and practice, and it
applies to contract formation and interpretation those usages which the parties
knew or ought to have known and which in international trade [are] widely
known to, and regularly observed by, parties to contracts of the type involved in
the particular trade concerned. Id. art. 9.45CISG,supranote 1, art. 14. It is not necessary, however, for the seller to
have identified the goods to the contract. In fact, the Commentary to the
Convention contemplates requirements contracts. United Nations Conference

CISG, a price would be fixed implicitly if the goods were subject to
a catalog price or a widely-ascertainable market price. Similarly,
the UCC provides that when a contract is formed with the price
left open, the price will be a reasonable price at the time of deliv-
ery.47
C. Firm Offers28
Under Article 16 (2)of the CISG an offer is effective when received,29
but it may be withdrawn before receipt. If the offer has been re-
ceived, however, it cannot be revoked:
(a) if it indicates, whether by stating a fixed time for accep-30
tance or otherwise, that it is irrevocable; or
(b) if it was reasonable for the offeree to rely on the offer as31
being irrevocable and the offeree has acted in reliance on the
offer.48
Under subsection (a), a dispute could arise as to whether the of-32
feroreffectively indicated that the offerwas irrevocable. Under sub-
section (b), a dispute could arise as to the reasonability of the of-
feree in relying on the offer being irrevocable. The potential for
misunderstanding, under both subsections, is exacerbated by the
different domestic laws on firm offer among the signatories.
For example, under traditional common law contract principles, an33
make a contract and there is a reasonably certain basis for giving an appropriate
remedy.47
U.C.C. ? 2-305(1) (1978) provides:The parties if they so intended can conclude a contract for sale even though the
price is not settled. In such a case the price is a reasonable price at the time for
delivery if (a) nothing is said as to price; or (b) the price is left to be agreed by
the parties and they fail to agree; or (c) the price is to be fixed in terms of some
agreed market or other standard as set or recorded by a third person or agency
and it is not so set or recorded.48CISG,supranote 1, art. 16(2).
offer is revocable at any time before acceptance is dispatched,
unless the offeror has promised not to revoke the offer and that
promise has been met with consideration. Under some circum-
stances, reliance may substitute for consideration. Where, for ex-
ample, a subcontractor submits an offer to a contractor and knows
the offer will be relied on in a bid, the subcontractor may not revokethe offer while the contractor is relying on it. In addition, the Uni-
form Commercial Code permits merchants to make a firm offer in
a signed writing and it is effective only for a reasonable period of
time, not to exceed three months.49
Under most civil law contract principles, an offer may be irrevo- 34
cable during the time necessary to make a response, or at least
it is irrevocable if the offeror reasonably relies on the offer. 50 In
the alternative, the offeror may be liable in tort for wrongful revoca-
tion of an offer, even if the revocation is effective in contract law. 51
Thus, traders in different signatory states will have different expe-riences with domestic law of firm offer and, presumably, different
concepts of what constitutes reasonable reliance. This is likely to
occasion confusion and misunderstanding about when an offer can
be revoked. Nevertheless, the language of Article 16(2) represents
a great improvement over previous efforts to codify a common in-
ternational trade law on firm offers.52
49U.C.C. ?2-205 provides that:
An offer by a merchant to buy or sell goods in a signed writing by its terms gives
assurance that it will be held open is not revocable, for lack of consideration,
during the time stated or if no time is stated for a reasonable time, but in noevent may such period of irrevocability exceed three months; but any such term
of assurance on a form supplied by the offeree must be separately signed by the
offeror.50SeeGalston and Smit, supranote 1, at 3-10, 3-12; Honnold, supranote 1, at
172-175 (1982).51Honnold,supranote 1, at 145-150.52Id. at 142-145.

D. Acceptance35
Under Article 18 of the CISG, acceptance may take the form of a36
statement made or by other conduct indicating assent. An accep-
tance is effective when it reaches the offeror.53 Conduct indicating
assent constitutes acceptance effective at the moment the act isperformed, and under Article 18(3) such conduct seems to cre-
ate a contract even if the offeror does not learn of the conduct. 54
In contrast, UCC 2-206 permits the offeror to treat the offer as
lapsed if beginning of performance is a reasonable means of ac-
ceptance andthe offeror is notnotifiedwithin reasonable time of the
offeree's performance.55 Under the CISG, the burden is passed on
to the offeror to ascertain whether the offeree has accepted the of-
fer through the performance of an act.
E. The Battle of the Forms37
Not infrequently, an offeree's purported acceptance contains terms38
at variance with the terms of the offer. Typically, the offer and ac-
ceptance are made on standard forms, each containing the terms
most favorable to the drafter of the form. Each party hopes that in
the event of a breakdown in the transaction, the terms contained in
53CISG,supranote 1, art. 18(1) and (2). Article 18(1) and (2) provides:
(1) A statement made by or other conduct of the offeree indicating assent to an
offer is an acceptance. Silence or incapacity does not in itself amount to
acceptance.
(2) An acceptance of an offer becomes effective at the moment the indication of
assent reaches the offeror. An acceptance is not effective if the indication ofassent does not reach the offeror within the time he has fixed or, if no time is
fixed, within a reasonable time, due account being taken of the circumstances of
the transaction, including the rapidity of the means of communication employed
by the offeror. An oral offer must be accepted immediately unless the
circumstances indicates otherwise.54CISG,supranote 1, art. 18(3). See Honnold,supranote 1, at 186-188.55U.C.C. ? 2-206 (1978).
his forms will be regarded by the court as the terms of the contract.
This classic fact pattern can result in what is called the battle of
the forms, and it is handled somewhat differently by the CISG and
the UCC.
Under the common law, a variation from the terms of the offer in 39
a purported acceptance resulted in a rejection and counter-offer. 56
The UCC alters the common law mirror image rule and treats a
reply that purports to be an acceptance as an acceptance, even if
it varies the terms of the offer, unless the acceptance is expressly
made conditionalon assentto theadditional or different terms. The
additional terms are construed as proposals for addition to the con-
tract. Between merchants, these termsbecome part of the contract
unless they materially alter the contract or are specifically objected
to within a reasonable time after notice is received. 57 Article 19 of
the CISG, however, takes a different approach. A reply that pur-
ports to be an acceptance, but contains terms that materially alter
the terms of the offer constitutes a counter-offer anddoes notserve
as an acceptance.58 Thus, a major difference in approach lies in
56Restatement (Second) of Contracts ?59. See Vergne,The Battle of the
Forms Under the 1980 United Nations Convention on Contracts for the
International Sale of Goods,33 Am. J. Comp. L. 233, 243 (1985).57U.C.C. ? 2-207(1) and (2) (1978) provides:
(1) A definite and seasonable expression of acceptance or written confirmation
which is sent within a reasonable time operates as an acceptance even though
it states terms additional to or different to from those offered or agreed upon,
unless acceptance is expressly made conditional on assent to the additional or
different terms.
(2) The additional terms are to be construed as proposals for addition to thecontract. Between merchants such terms become part of the contract unless:
(a) the offer expressly limits acceptance to the terms of the offer;
(b) they materially alter it;
(c) notification of objection to them has already been given or is given within a
reasonable time after notice of them is received.

the result that, under the UCC, a purported acceptance that materi-
ally alters the terms of the offer results in a contract on the offeror's
terms. Under the CISG, however, a purported acceptance that ma-
terially alters the terms of the offer results in no contract. The reply
is regarded as a counter-offer and may be accepted by the original
offeror. Commentators have suggested that the CISG approachconforms more closely to both the mirror image rule and to west-
ern European civil code than does the UCC. 59
Under the CISG, if the purported acceptance contains additional40
or different terms that do not materially alter the terms of the offer,
then the reply serves as an acceptance, unless the offeror, with-
out undue delay, objects orally to the discrepancy or dispatches a
notice to that effect60 Then, as under the UCC, if the offeror does
not object, there is a contract on the terms of the offer as modified
by the acceptance. Unlike the UCC, however, the CISG specif-
ically identifies those terms that materially alter the terms of the
offer. Such terms include among other things, price, payment,
quality, quantity, time and place of delivery, extent of one party's
liability to the other or the settlement of disputes under the con-
tract.61 However exhaustive this list may appear, there is still room
to construe material in light of trade practice and course of deal-
ing. Inevitably, materiality, too, will be determined in the light
of commercial practice or good faith,62 as that is understood by
judges in different countries and legal traditions.
IV. The Risk of Loss41
The CISG provides basic rules for fixing the risk of loss or damage 42
to goods.63 Like the UCC, the CISG addresses the specific fact sit-
uations that inhere in the sale of goods. When goods are in transit,
and particularly when goods are transferred in transit among differ-ent modes of transport, it may be exceedingly difficult to fix in time
the incidence of damage or loss. Roman law placed the transfer of
the risk of loss at the conclusion of the contract.64 Some western
civil law countries have retained this rule, or have placed the time
of transfer of the risk at the time of the transfer of ownership. 65 It
is highly practical to fix the time of transfer of the risk of loss or
damage at a clearly ascertainable point, independent of the facts
that give rise to the loss. Usually, this would be either at the time
the goods are handed over to the carrier by the seller,and subject
to inspection by the seller at that point, or when the goods are de-
livered by the carrier to the buyer, and subject to the inspection bythe buyer at that point.66
It would be efficient to permit theparties to determinethe better risk 43
bearer, and recognize the allocation of risk made by the parties. In

fact, that approach is taken in both the UCC and the CISG. Typ-
ically, the risk is allocated by the parties through the use of UCC
terms for shipment or delivery contracts67 in domestic transactions,
or by reference to INCOTERMS68 in international transactions. In
the absence of an allocation of risk by the parties, however, the
CISG provides a rule of risk allocation, depending on whether thegoods are to be transported, are in transit at the time of the sale,
or are to be sold without transport. The effect of the rule of risk al-
location in each of these fact situations is that the buyer is not dis-
charged from his obligation to pay the contract price of the goods
if the risk of loss has passed to him under the rule. An exception is
made for loss or damage due to an act or omission of the seller. 69
In addition, breach of the contract causes the risk of loss to remain
on the seller.70 Similarly, the seller's failure to disclose damage or
loss known at the time of the conclusion of the contract causes the
seller to retain the risk of loss or damage.71
67U.C.C. ?2-509(1) provides:
(1) Where the contract requires or authorizes the seller to ship the goods by
carrier
(a) if it does not require him to deliver them at a particular destination, the risk of
loss passes to the buyer when the goods are duly delivered . . . ; but
(b) if it does require him to deliver them at a particular destination and the goods
are there duly tendered while in the possession of the carrier, the risk of loss
passes to the buyer when the goods are there duly so tendered as to enable the
buyer to take delivery.68SeeInternational Chamber of Commerce, International Rules for the
Interpretation of Trade Terms, I.C.C. Pub. No. 350 and International Chamber of
Commerce, Guide to Incoterms (1980). The International Chamber of
Commerce has promulgated accepted meanings of specific trade terms, suchas FAS (free alongside ship), CIF (cost, insurance, freight), and CandF
(cost and freight).69CISG,supranote 1, art. 66.70Id. art. 79. Article 79 provides: If the seller has committed a fundamental
breach of contract, article 67, 68 and 69 [on risk of loss] do not impair the
remedies available to the buyer on account of the breach.71Id. art. 69. Article 69 provides, in salient part: Nevertheless, if at the time of
A. Goods to Be Transported 44
Article 67 of the CISG provides the following rule on risk of loss or 45
damage:
(1) If the contract of sale involves carriage of the goods and 46
the seller is not bound to hand them over at a particular place,the risk passes to the buyer when the goods are handed over
to the first carrier for transmission to the buyer in accordance
with the contract of sale. If the seller is bound to hand the
goods over to a carrier at a particular place, the risk does not
pass to thebuyeruntil the goods arehanded over to the carrier
at that place. The fact that the seller is authorized to retain
documents controlling the disposition of the goods does not
affect the passage of the risk.
(2) Nevertheless, the risk does not pass to the buyer until the 47
goods are clearly identified to the contract, whether by mark-
ings on the goods, by shipping documents, by notice given to
the buyer or otherwise.72
This provision reflects the general approach of the UCC, in which 48
the risk of loss passeswhen the seller hascompleted his obligation
with respect to physical transfer of the goods. Under 2-319 of the
UCC, if the seller is obligated under the contract terms to put the
goods into the hands of a carrier, then the risk of loss passes to the
buyer when the seller puts the goods in the hands of a carrier.73 If
the seller is obligated to deliver the goods to a carrier at a particu-
lar port, then the risk of loss passes when the seller completes this
delivery alongside the ship.74 Finally, if the seller is obligated to de-
the conclusion of the contract of sale the seller knew or ought to have known
that the goods had been lost or damages and did not disclose this to the buyer,
the loss or damage is at the risk of the seller.72Id. art. 67.73U.C.C. ?2-509(1); U.C.C. ?2-319(1).74U.C.C. ?2-509(1); U.C.C. ?2-319(2).

liver the goods to their final destination, then the risk of loss passes
when the seller delivers the goods to that destination.75
There are difficulties, however, with the first carrier rule, partic-49
ularly where the seller is obligated to transport the goods to the
particular place and does so by transporting the goods in its own
trucks. Commentators have observed that in this fact situation, thebuyer, in effect, assumes the risk of loss even when the goods
are in the hands of the seller.76 As a practical matter, the time
of the damage to the goods will be indeterminable if the nature of
the damage is breakage, seepage, freezing, overheating, theft or
other covert injury, and the buyer will bear the risk. This is a prac-
tical, albeit probably unintended, effect of the rule. Similarly, if the
seller contracts with a carrier to transport the goods to the par-
ticular place, and the goods are damaged in a manner not easily
ascertainable, the buyer will bear the risk of loss as a practical mat-
ter, even though the intent of the CISG appears to be otherwise.
Both of these problems underline the importance of avoiding shift-ing the risk of loss of goods, whether by treaty or by contract, while
they are actually in transit.77
Article 67 does not appear to cover destination contracts, in which50
the seller is obligated to deliver physical possession of the goods
to the buyer. Article 69, however, provides:
(1) In cases not within articles 67 and 68, the risk passes to51
the buyer when he takes over the goods or, if he does not do
so in due time, from the time when the goods are placed at his
disposal . . .
(2) However, if the buyer is bound to take over the goods to52
a place other than a place of business of the seller, the risk

Introduction to Comparative Law 187-207 (1977).
passes when delivery is due and the buyer is aware of the fact
that the goods are placed at his disposal at that place. 78
This provision is, in part, a reciprocal of article 67. 79 The articu- 53
lation, however, is not complete. Article 69(2) appears on its face
to address fact situations where the goods are to be sold without
being moved by the seller or from the seller's place of business. Itwould apply where, for example, the goods were to be moved by
the buyer from a warehouse operated by a third party, and it would
pass the risk of loss at the time delivery is due and the buyer is
aware that the goods are placed at his disposal at that place. This
fact situation was contemplated by the drafters.80
Article 67 appears to cover shipment contracts, where the seller 54
is obligated to turn goods over to a third party carrier either at the
seller's place of business (first sentence of article 67(1)) or at a
distant point to be then transported by carrier to the buyer (second
sentence of article 67(1)). Article 69 appears to cover destinationcontracts. Thus, if the seller is obligated to deliver the goods to
the buyer's place of business or to a place where the buyer is to
take over the goods, Article 69 would apply. It has been pointed
out in commentary, however, that the CISG is silent on the problem
of goods sent to a buyer under a shipping term such as Ex Ship
Buyer's Port. Under INCOTERMS, this term designates that the
seller's liability ends when the goods are off-loaded at the port and
placed at the disposal of the buyer. Article 69(2) would produce the
same result. Arguably, however, a liberal reading of Article 67(1)
(second sentence) would makethat provision applicable and cause
the risk of loss to pass to the buyer at a later point. That result canbe avoided by reading literally the language of Article 67(1) that
refers to the seller's obligation, not the carrier's obligation, to hand

the goods over to a carrier. A parallel construction of Article 69(2),
however, would make that provision inapplicable where the buyer's
carrier, not the buyer, is to take over the goods. This ambiguity
underscores the need to use INCOTERMS to obviate this practical
construction problem.81
B. Good Not to Be Transported55
Article 69(1) provides that if the goods are to be picked up by the56
buyer at the seller's place of business, the risk is allocated to the
buyer when the goods are placed at his disposal. This language
requires factual evidenceof buyer's and seller's knowledge. In con-
trast, UCC 2-509(3) addresses this fact situation by passing the
risk of loss to the buyer on his receipt of the goods if the seller is
a merchant . . .82 This language appears to provide a more easily
ascertainable moment in time for risk-shifting. It also provides an
opportunity for the buyer to inspect the goods beforetaking receipt,
and that opportunity provides greater certainty as to who bore the
risk of loss or damage if loss or damage has occurred.
Article 69(2), which appears to be an exception to article 69(3),57
provides for the risk of loss where the buyer takes over the goods
at a place other than the place of business of the seller, such as
a bailee or warehouse. The risk of loss passes when delivery is
due and the buyer is aware that the goods are placed at his dis-
posal. Thus, it turns on factual knowledge of the buyer. In contrast,
UCC 2-509(2) provides a far more easily ascertainable standard
for identifying the risk of loss.83 The CISG language appears toprovide an unnecessarily subjective approach to determining risk
of loss, particularlyin comparison with theUCC language. It seems

prudent for traders to specify an allocation of risk provision in their
salescontractso as to avoidthe possible complications of theCISG
approach.
V. Performance 58
Most of the provisions of the CISG on contract performance are fa- 59
miliar to the American commercial lawyer because they resemble
the analogous UCC provisions. The seller is obliged to deliver the
goods, hand over any documents and transfer the property in the
goods, as required by the contract and the CISG. 84 If the seller is
not bound to deliver the goods at a particular place, then he is ob-
ligated to hand the goods over to the first carrier for transmission
to the buyer or to place the goods at the buyer's disposal. 85 If the
seller is obligated under the contract to arrange for carriage of the
goods, he must make such contracts as are necessary for car-riage to the place fixed by means of transportation appropriate in
the circumstances and according to the usual terms for such trans-
portation.86 The seller must deliver the goods at the contractually
agreed time, or within a reasonable time if no time is specified.87
Necessary documents must be handed over to the buyer as re-
quired by the contract.88
Under the CISG, the seller must provide goods which, in addition 60
to meeting contract specifications, meet standards of the CISG
which are similar to the implied warranty of merchantability under
84CISG,supranote 1, art. 30. See Enderlein,Rights and Obligations of the

form to a model or description, and be packaged or contained in
the manner usual for such goods or, where there is no such man-
ner, in a manner adequate to preserve and protect the goods.90
In addition, the seller must meet a standard similar to the UCC's
implied warranty of fitness for a particular purpose.
91
The selleris liable for any lack of conformity that exists at the time the buyer
assumes the risk of loss, even if the lack of conformity does not be-
come apparent until after the risk of loss has shifted.92 However, if
the seller has delivered non-conforming goods before the due date
of delivery, the seller may cure93 a breach of conformity up until
the due date of delivery by delivering any missing parts, making up
deficiencies in quantity, or delivering replacement goods.94
The buyer's obligations are also similar in many respects to those61
of the buyer under the UCC. The buyer is obligated to pay the price
of the goods95 and to take delivery of the goods.96 In addition, the
buyer is obligated to examine thegoodswithin as short a period as
is practicable in the circumstances,97 andthis examination maybe
deferred until shipped goods arrive at their destination.98 In order
to preserve his right to rely on a lack of conformity of the goods,
the buyer must give notice to the seller specifying the nature of
lack of conformity within a reasonable time after he has discov-

ered [the lack of conformity] or ought to have discovered it. 99 In
any event, the buyer must notify the seller of the lack of conformity
within two years after receiving the goods, unless that period is in-
consistent with the period of guarantee specified in the contract.
The opportunity for late discovery of non-conformity permits the
buyer to assert claims against the seller based on hidden defectsin the goods, or defects not reasonably discoverable on immediate
inspection.
A major distinction between the CISG and the UCC approach to 62
performance lies in the fact that under the CISG there is no explicit
perfect tender rule100 permitting the buyer to reject the goods for
lack of conformity. The buyer under the CISG may, in effect, reject
the goods only if their non-conformity amounts to a fundamental
breach of the contract. Otherwise, the buyer is left to remedies for
99Id. art. 39(1). See Patterson,supranote 2, at 284-294 for a discussion of the
nature of the compromise that his provision represents between developing and
developed nations. In brief, nations that primarily buy industrial goods regardthe sanction for failing to notify the seller of non-conformity of the goods to be
too harsh -- such a buyer loses the right to rely on non-conformity of the goods
as a defense to non-payment. Moreover, buyers of technically complex
machinery perceive that defects in goods may not be readily ascertainable, that
sufficient time for inspection, testing and operations must be provided to detect
latent defects in goods. Sellers of such goods, on the other hand, perceive the
need for finality in sales, particularly with geographically distant buyers whom
they fear may unreasonably withhold approval of the goods to gain a strategic
advantage in price. The role of a trade treaty is to balance these concerns and
provide reasonable certainty of expectations. Article 39, requiring notice within a
reasonable time, normally not to exceed two years, reflects this compromise. Id.
The critical tension in judicial decisions under article 39 will be the commercial
standards which the forum court employs -- those of more industrial or lessindustrial nations -- in determining whether the buyer gave notice of
nonconformity within a reasonable period. Id. at 301-302.100U.C.C. ?2-503(1) provides, in part: Tender of delivery requires that the seller
put and hold conforming goods at the buyer's disposition and give the buyer any
notification reasonably necessary to enable him to take delivery . . . .
Tender that is rejected for non-conformity may be cured by the seller pursuant
to U.C.C. ?2-508.

breach of contract. In contrast, under 2-601of the UCC, thebuyer
is entitled to reject or accept the goods if the goods or the tender
of delivery fail in any respect to conform to the contract . . .101
This provision is designed to take account of the relatively difficult
position of the seller in an international transaction when goods
are rejected by the buyer for a minor defect or imperfect tender ofdelivery. Given the significant asymmetry of power between the
seller and the buyer at that point, the remedies available under the
CISG appearsufficient to protect thelegitimate needsand interests
of the buyer.
A. Fundamental Breach63
The concept of fundamental breach is central to the CISG. Article64
25 provides:
A breach of contract committed by one of the parties is fun-65
damental if it results in such detriment to the other party as
substantially to deprive him of what he is entitled to expect
under the contract, unless the party in breach did not foresee
and a reasonable person of the same kind in the same circum-
stances would not have foreseen such a result. 102
This definition of fundamental breach appears to permit judgment66
as to whether avoidance of the contract is necessary to protect
the non-breaching party. Remedies available to the buyer turn on
whether the seller's breach was fundamental. Under article 49, for
example, the buyer may declare the contract avoided if the seller'sfailure to perform amounts to a fundamental breach. 103 Similarly,
a fundamental breach by the buyer is a basis for the seller avoid-
101U.C.C. ?2-601 (1978).102CISG,supranote 1, art. 25.103Id. art. 49.
ing the contract under article 64.104 If the non-conformity of goods
constitutes a fundamental breach of the contract, the buyer may
require that the seller provide substitute goods. 105 Avoidance of
the contract releases both parties from their obligations under the
contract, leaving them subject to any damages.106
In contrast, the UCC does not require that a breach of a sales con- 67
tract be so severe as to substantially deprive the non-breaching
party of thebenefit of hiscontract in order to permitavoidance of the
contract. A buyer may reject non-conforming goods, subject only
to the requirement that he permit timely re-tender of conforming
goods. If the buyer accepts the goods, he can revoke acceptance
and avoid his own performance only if its non-conformity substan-
tially impairs its value to him, and either (1) he has accepted the
goods knowing of the non-conformity but on the reasonable as-
sumption that the non-conformity would be cured, or (2) his accep-
tance was reasonably induced either by the difficulty of discovery
before acceptance or by the seller's assurances.107
Article 26 provides that a contract may be effectively avoided only 68
if notice is made to the other party. This relatively simple rule
represents a significant improvement over the Hague Convention
on Sales, which permitted the ipso fact avoidance, whereby the
breaching party could continue to perform at his own peril, igno-
rant of the fact that the non-breaching party had avoided the con-
tract.108 The drafters of the CISG sought to produce a rule that
looked at the severity of the breach, in the light of the foreseeable
consequences of the breach, rather than at the subjective knowl-
edge of the parties at the time of contract, which was the approach104Id. art. 64.105Id. art. 46(2).106SeeVilas,Provisions Common to the Obligations of the Seller and the
Buyer,in Volken and Sarcevic, supranote 1, at 255-59.107U.C.C. ?2-608 (1978).108SeePatterson,supranote 2, at 294-296.

taken by the Hague Convention.109 While the severity of a breach,
and the extent to which it impairs contract expectations, may be
perceived differently against the background of domestic law, the
CISG approach appears superior as an international code.
B. Good Faith69
Article 7(1) provides that in interpreting the Convention there shall70
be regard for promoting the observance of good faith in interna-
tional trade.110 Unlike the UCC, however, the CISG does not at-
tempt to define what behavior constitutes evidence of good faith,
and the CISG falls short of declaring good faith to be a necessary
part of each party's performance. The UCC's good faith require-
ment is clearly broader in principle: Every contract or duty within
this Act imposes an obligation of good faith in its performance or
enforcement.111 The uncertain meaning of the CISG good faith
provision undoubtedly will provide opportunity for national courts
to impose local concepts of business ethics and, therefore, for lack
of uniformity in interpretation.112
C. Excuse of Performance71
Article 79 of the CISG provides:72
(l) A party is not liable for a failure to perform any of his obli-73
gations if he proves that the failure was due to an impediment
beyond his control and that he could not reasonably be ex-pected to have taken the impediment into account at the time
109Honnold,supranote 1, at 212-213.110Id. art. 7(1). See Unification and Certainty,supranote 6, at 1991 n.41.111U.C.C. ?1-203.112Unification and Certainty,supranote 6, at 1991.
of the conclusion of the contract or to have avoided or over-
come it, or its consequences.113
Article 79 further provides that the party who fails to perform be- 74
cause of an impediment must give notice to the other party of the
impediment and its effect on its ability to perform, or else stand li-
able for damages resulting from the lack of notice.114 This broad
provision reflects a compromise between the force majeure doc-
trine of the civil law countries and the relatively narrower excuse
for non-performance found in the common law doctrine of impos-
sibility.115
Section 2-615 of the UCC provides a somewhat stricter standard, 75
excusing failures to deliver goods if performance as agreed
has been made impracticable by the occurrence of a contin- 76
gency the non-occurrence of which was a basic assumption
on which the contract was made.116 Thus, the CISG looks tothe unexpected and permits excuse for performance where an
unexpected contingency occurs, while the UCC standard appears
to permit non-performance where the contingency that prevents
performance was anticipated, and the risk of that contingency
was not on the party whose performance was prevented. The
term impediment is not defined in the CISG. Undoubtedly, the
national courts that resolve conflicts under this provision will draw
heavily upon their own approaches to impossibility. To the extent
this happens, the goals of certainty and uniformity of international
trade law are compromised.117

The United Nations Convention on Contractsfor the International Saleof Goods
VI. Remedies77
A. Buyers' Remedies78
If the seller fails to perform his obligations, the buyer has a selec-79
tion of possible remedies. The buyer may require specific perfor-
mance of the contract, unless he has resorted to a remedy that is
inconsistent with specific performance. If the non-conformity of the
goods constitutes a fundamental breach of the contract, the buyer
may require delivery of substitute goods. Even if the breach is not
fundamental, the buyer may require the seller to repair the non-
conforming goods, unless it would be unreasonable to require the
seller to do so.118
The availability of specific performance would come as a surprise80
to the unsuspecting common law merchant. Historically, the com-
mon law has regarded specific performance as an equitable rem-
edy, available only where monetary damages would prove an in-adequate remedy. Under UCC 2-716, a buyer may seek spe-
cific performance where the goods are unique or in other proper
circumstances, or, in some circumstances, the buyer may seek
replevin of the goods.119 Civil law systems tend to make specific
performance more readily available to the buyer.120 The general
rule of article 46 favoring specific performance is closer to the civil
law approach. However, article 28 permits the forum court not to
apply theremedy of specific performance if it would notdo so under
the substantive law of the forum state.121 Thus, the availability of

Law 79 (1984).119U.C.C. ? 2-716.120Honnold,supranote 1, at 227.121CISG,supranote 1, art. 28 states:
If, in accordance with the provisions of this Convention, one party is entitled to
require performance of any obligation by the other party, a court is not bound to
specific performance will vary, depending on the law of the forum
state, posing the possibility of surprise for either common law or
civil law merchants.
In addition, the CISG evidences a solicitude for the interests of the 81
seller in curing defective performance of the contract. The buyer
has the option of fixing an additional period of time for the seller to
perform his obligations, and during that period he may not resort
to any other remedy for the breach, unless he receives notice that
the seller will not perform.122 He may, however, claim damages
for the delay. Failure of the seller to perform within the extended
period entitles the buyer to avoid the contract, even if the breach
was not fundamental.123 In addition, the seller may cure a non-
fundamental breach even after the date of delivery if he can do
so without unreasonable delay and without causing the buyer un-
reasonable inconvenience or uncertainty of reimbursement by the
seller of expenses advanced by the buyer.124 Unless the buyer
has avoided the contract and notified the seller, the seller may no-
tify the buyer that he will perform within a specified period of time.
Such a notice is assumed to include a request that the buyer make
known whether he will accept performance. If the buyer does not
comply with the request within a reasonable time, the seller may
perform within the time indicated in his request. During this pe-
enter a judgement for specific performance unless the court would do so under its
own law in respect of similar contracts of sale not governed by this Convention.

The United Nations Convention on Contractsfor the International Saleof Goods
read in conjunction with article 77, which requires a party who re-
lies on a breach of contract to take reasonable measures to miti-
gate the loss, including loss of profit, resulting from the breach, or
to be treated in the damage award as though he had taken such
measures.135
If the contract has been avoided, the party may have a more spe-92cific damage claim. The avoiding buyer who covers in the market
place, as well as the avoiding seller who resells the goods, has a
right to recover the difference between the contract price and the
price in the substitute transaction as well as further damages un-
der article 74.136 Under article 76(1), if the avoiding party has not
made a substitute transaction, he may nevertheless claim dam-
ages based on the difference between the price fixed by the con-
tract and the current price at the time of avoidance as well as dam-
ages under article 74. The problem of identifying the appropriate
market for determining such a price is addressed in article 76(2),
which refers to the price prevailing at the place where delivery ofthe goods should have been made or, if there is no current price at
that place, the price at such other place as serves as a reasonable
substitute, making due allowances in the cost of transporting the
goods.137
D. Restitution93
In addition to money damages, if the contract has been avoided,94
the buyer or seller who has performed the contract may claim resti-
tution in an amount equivalent to whatever he has supplied or paid
under the contract.138 If the buyer has received the goods and is
unable, due to his own act or omission, to make restitution of them
135Id. art. 77.136Id. art. 74.137Id. art. 76(2).138Id. art. 81.
in substantially the condition he received them, he loses the right
to declare the contract avoided.139 The buyer does not lose the
right to avoid, however, if the goods have perished or deteriorated
as a result of the buyer's exercise of his right of inspection, or if the
goods have been sold in the normal course of business or have
been consumed or transformed by the buyer in the course of nor-
mal use before he discovered or ought to have discovered the lack
of conformity.140 Finally, in making restitution, the buyer must ac-
count to the seller for all benefits which he has derived from the
goods. If he cannot return the goods under an avoided contract,
he must account to the seller for the disposition of the goods. 141
Similarly, the seller who is bound to refund the price of goods in
restitution must pay interest from the date on which the price was
paid.142
The remedies of buyer and seller are intended to maintain a bal- 95
ance of fairness between the parties in a long-distance trading re-
lationship and to prevent either party from gaining the capacity todeal with the other in an overbearing manner. For example, spe-
cific performance may be a sensible remedy for the seller faced
with a recalcitrant buyer who refuses, unreasonably, to take deliv-
ery of conforming goods. On the other hand, the seller is required
to mitigate damages, so that the buyer is likely to be faced with
specific performance only where the seller has no effective way to
mitigate through a resale of the goods. In addition to balancing the
rights of the parties, this feature of the Convention also balances
the civil law and common law approaches to remedies. Similarly,
the capacity of eitherpartyto fix an additional periodof time for per-
formance, and insist on either performance or breach, may reflectthe need for greater certainty in dealing at a distance. In general,

The United Nations Convention on Contractsfor the International Saleof Goods
however, the remedy and damage provisions of the CISG are con-
sistent with the overall approach of the UCC, and the American
lawyer should be comfortable with them.
VII. Conclusion96
The Convention of the International Sale of Goods has now be-97
come an important part of American commercial law. This piece
of the legal puzzle must be understood as a document designed
to harmonize and bridge legal, developmental and cultural differ-
ences in the international setting. While several of its important
provisions are not found in American commercial code law, many
Uniform Commercial Code concepts are reflected in the Conven-
tion. This is not surprising since the UCC is designed to harmo-
nize differences, albeit lessdramaticdifferences, among the states.
Moreover, it is clear that some areas of potential conflict have not
been addressed by the Convention. Thus, it is important to under-stand the scope and coverage of the Convention. In addition, it is
useful to identify the most significant provisions of the Convention
that depart from the UCC approach.
This paper has provided a descriptive analysis of the major as-98
pects of the Convention's scope and coverage. While the CISG
addresses the formation of contracts and the rights and obligations
of the seller and buyer, it does not address other salient aspects of
a sales contract, such as contract validity, product liability, capac-
ity of the parties, or commercial fraud. Thus, the contract drafter
must draft around these gaps in coverage, at the same time identi-fying any unexpected areas covered by the Convention. Similarly,
the Convention does not cover contracts for the sale of goods to
consumers.
In addition, the paper has analyzed the problematic aspects of the99
provisions on the formation of the contract, allocation of the risk of
loss, performance, and remedies. The thrust of this analysis has
been both to identify significant departures from American com-
mercial law and to identify areas of the Convention that may create
difficulty in achieving certainty and uniformity in international trade
law. The most problematic areas for an American traderare: 1) the
issues of coverage and inclusion and the choice of law appropriate
to those areas not covered by the Convention; 2) the ambiguities
inherent in a view of contract formation that seeks to identify the
time of contract conclusion through an offer and acceptance anal-
ysis; 3) the Convention's approach to modifications and alterations
of an offer in a purported acceptance; 4) the uncertainties intro-
duced by the first carrier approach to allocation of the risk of loss;
5) the use of substantial performance theory instead of a perfect
tender rule; 6) the concept of the fundamental breach; 7) the rel-
atively broader excuse of performance doctrine; and 8) the buyer's
right to reduce the price as a remedy in breach.
