6.Current Condition

This is compulsory standard to come into effect on August 1 ,2015

It is possible for China to put lithium ion cells and batteries into CCC catalogue based on this standard .

The laboratory of Shanghai Research Institute of Chemical industry was the contracted laboratory of CQC (China quality center )

Shanghai Research Institute of Chemical Industry

6. Current Condition

CQC will issue the volunteer certification with SRICI’s test data and will issue CCC certification if lithium ion cells and batteries are put into CCC catalogue.

You will get one UN38.3 free if you apply for UN38.3 and GB31241 at the same time .
