Is explosion-proof product certification the same as CCC certification? — An Answer from Shenzhen ZhongNuo Testing Technology Co., Ltd.
Explosion-proof product certification generally refers to the safety certification required for explosion-proof products to enter the market, also known as explosion-proof certification. The certificate issued is called an Explosion-Proof Certificate.
CCC Certification, which stands for "China Compulsory Certification," is abbreviated as CCC.
The CCC certification mark is "CCC," which is a product certification system established by the Certification and Supervision Commission in accordance with the "Administrative Regulations on 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 mandatory product certification scope under market supervision.
It means that certain explosion-proof electrical equipment must be compulsorily applied for a 3C certification to enter the market and be circulated in operation.
Some explosion-proof products are included in the CCC certification scope.
But explosion-proof product certification is not equivalent to CCC certification.
Only explosion-proof products within the CCC Certified Product Catalog need to apply for the CCC certification; explosion-proof products outside the catalog only require an explosion-proof compliance certificate.

Can coal safety certification be converted to a explosion-proof 3C certification? - Answer from Shenzhen ZhongNuo Inspection Technology Co., Ltd.
Based on the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been added to the mandatory product certification catalog.
It is the CCC certification. Products under the explosion-proof 3C certification category obtain the explosion-proof CCC certification by undergoing a "type test + factory audit" certification process.
Coal Safety Certification, abbreviated as MAC, is a mandatory certification implemented by the Safety Standardization Center for all types of products and equipment used underground in coal mines.
The certification method is a combination of "type testing" and "factory audit."
Currently, mandatory product certification bodies and coal safety certification bodies are under different departments.
There is no mutual recognition between them. Coal safety certification and explosion-proof 3C certification are independent of each other.
The coal safety certification or the explosion-proof 3C certification cannot be substituted or converted for each other; they must be applied for separately.
