Can coal safety certification be converted to explosion-proof 3C certification? - Answer from Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.
Based on the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been transferred 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 is the abbreviation for Coal Mine Safety Certification, which is a mandatory certification conducted by the Safety Standardization Center for various products and equipment used underground in coal mines.
The certification method combines "type testing" with "factory audit."
Currently, mandatory product certification bodies and coal safety certification bodies are under different departments, with 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.

In July 2019, the market issued an announcement regarding the implementation of a mandatory product certification for explosion-proof electrical products and other items, transitioning from production licenses.
The announcement explicitly states that as of October 1, 2019, explosion-proof electrical equipment, household gas appliances, and household refrigerators with a rated volume of 500L or more are included in the CCC certification management scope.
And the transition period is one year, starting from October 1, 2020, the above products must not be certified with a mandatory product certification and must not bear the mandatory certification mark.
Not for sale, distribution, import, or use in any business activities.
This means that in the future, applying for an explosion-proof certification will become a mandatory CCC certification, and will be implemented in accordance with the rules of the mandatory CCC certification.
