What are the requirements for companies applying for the mandatory product certification (CCC certification) after converting explosion-proof electrical products?
ZhongNuo Inspection: Mandatory Product Certification, also known as CCC Certification, involves a certification model that includes type testing, initial factory inspection, and post-certification supervision. In simpler terms, it requires a factory audit. Applicant companies must possess production/inspection/shipment capabilities (or OEM/ODM).

Is explosion-proof product certification the same as CCC certification? — An Answer from Shenzhen Zhongnuo Testing Technology Co., Ltd.
We refer to explosion-proof product certification as the safety certification required for explosion-proof products to enter the market, commonly known as explosion-proof certification, and the certificate issued is called an explosion-proof compliance certificate.
CCC Certification, which stands for "China Compulsory Certification," is abbreviated as CCC.
The CCC certification mark is denoted as "CCC" and represents the product certification system established by the Certification and Supervision Commission in accordance with the "Regulations for Compulsory Product Certification" (Order No. 5 of the China Quality Supervision and Inspection and Quarantine Commission).
As of October 1, 2019, explosion-proof electrical products were officially included in the scope of mandatory product certification under market supervision.
Means that some explosion-proof electrical equipment must be compulsorily applied for a 3C certification to enter the market for operation and circulation.
Some explosion-proof product certifications are included in the CCC certification scope.
But explosion-proof product certification does not equate to CCC certification.
Only products within the防爆CCC certification catalog need to apply for the CCC certification.
Explosion-proof products outside the catalog only require an explosion-proof certificate.
