After the防爆CCC certification has replaced the production license, is a防爆qualification certificate still required?
ZhongNuo Inspection: Since the release in July 2019 of market-related regulations on explosion-proof electrical products and more
Following the announcement of the transition from production license to mandatory product certification management implementation requirements,
Many companies producing explosion-proof electrical products have gained some understanding of the explosion-proof 3C certification system.
But, does the implementation of the explosion-proof 3C certification system replace the original explosion-proof qualification certificate?
In fact, a careful reading of this announcement reveals that only certain types of explosion-proof electrical products are included in the scope of mandatory product certification (for details, refer to the product catalog of mandatory explosion-proof electrical product certification).
There are still a large number of explosion-proof products not included in the market, such as common pressure transmitters, combustible gas detectors, breathing valves, intelligent scanning terminals, dust removal equipment, and mechanical products, etc.
Explosion-proof equipment installed and used in explosive areas, outside of the product catalog, must strictly comply with the requirements of the GB/T3836 series explosion-proof standards and obtain the corresponding explosion-proof certification.

Can coal safety certification be converted to explosion-proof 3C certification? - Answer from Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.
According to the announcement, as of October 1, 2020, certain explosion-proof electrical equipment will be 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 method.
Coal Safety Certification, abbreviated as MAC, is a mandatory certification implemented by the Safety Standardization Center for all kinds of products and equipment used underground in coal mines.
The certification method is a combination of "type testing + factory audit."
Currently, mandatory product certification bodies and coal safety certification bodies are under different departments, with no mutual recognition between them.
The 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 converting the production license for explosion-proof electrical products and similar items into a mandatory product certification.
The announcement clearly states that as of October 1, 2019, explosion-proof electrical equipment, household gas appliances, and domestic refrigerators with a rated volume of over 500L will be 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, enterprises applying for explosion-proof certification will be required to undergo the CCC mandatory certification, and will be executed in accordance with the implementation rules of the CCC mandatory certification.
