The China Compulsory Certification (CCC) is a mandatory conformity assessment system for products imported and sold in China. It was first implemented in 2002 by the China Certification and Accreditation Administration (CNCA) to ensure standardized product quality and safety. Explosion protected products (Ex products) are required by law to obtain the CCC Mark starting from October 1, 2020. 


The CCC certification process includes three main parts: (1) Type test which entails product evaluation, testing and certification at the CNEx laboratories; (2) initial factory inspection of the manufacturer’s facilities by CCC Ex auditors appointed by the certification body; and (3) post-certification supervision, which informs renewal of the CCC certificate.


When a product goes through the certification process for the first time, CNEx conducts a final comprehensive review of results from part (1) the type test and part (2) the initial factory audit and draws a conclusion of either CCC issuance or termination (for which reasons will be provided for improvement). An initial CCC certificate is valid for up to five years and can be renewed through post-certification assessment starting from 3 months before expiration date.
