We have an extensive portfolio of consulting cases in the field of explosion-proof 3C certification. We are well-versed in the application process and technical requirements for explosion-proof 3C certification, and can provide clients with consulting services such as application assistance and factory audit guidance.
Which institution can apply for the explosion-proof 3C certification and 3C factory audit?
The防爆3C Certification is for explosion-proof electrical products listed in the explosion-proof 3C catalog.
Adopt the "type test + factory audit" approach; the factory can be its own, or an OEM or ODM factory.
This certification is divided into two sections.
Firstly, product Testing is conducted in accordance with the GB/T3836 standard, followed by issuance of a Type Testing Report upon successful completion of the Testing.
Firstly, conducting factory audits, which we refer to as "factory inspections," involves on-site evaluations of the production facilities.
There are numerous 3C certification bodies, but finding one capable of handling explosion-proof 3C certifications is crucial.

After the explosion-proof CCC certification has replaced the production license, do we still need an explosion-proof compliance certificate?
ZhongNuo Inspection: Since the release in July 2019 regarding explosion-proof electrical products and the like in the market
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 a certain 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?
Actually, just by carefully reading this announcement, you can understand that,
The announcement only includes a portion of explosion-proof electrical products in the scope of mandatory product certification.
(For details, see the Product Catalog for the Mandatory Product Certification of Explosion-Proof Electrical Appliances.)
A significant portion of explosion-proof products have not yet been included in the market.
For example, common pressure transmitters, flammable gas detectors, breathing valves, pressure sensors, dust removal equipment, and mechanical products.
Extraneous to the product catalog, explosion-proof equipment installed and used in explosive areas must strictly comply with the requirements of the GB/T3836 series explosion-proof standards.
Obtain the corresponding explosion-proof certification.

After the explosion-proof CCC certification has replaced the production license, is an explosion-proof compliance certificate still required?
Since the issuance of the market supervision regulations on explosion-proof electrical products, etc., in July 2019
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 a certain 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?
Does the product need an explosion-proof certificate to enter the market?
What additional conditions are required for a company to produce explosion-proof electrical products?
Actually, a careful reading of this announcement reveals that...
The announcement only includes a portion of explosion-proof electrical products within the scope of mandatory product certification.
(For details, see the product catalog of the mandatory explosion-proof electrical product certification.)
There is still a large portion of explosion-proof products not included in the market.
For example, common pressure transmitters, flammable gas detectors, breathing valves, dust removal equipment, and mechanical products, etc.
Extraneous to the product catalog, explosion-proof equipment installed and used in explosive areas must strictly comply with the requirements of the GB/T3836 series explosion-proof standards.
Obtain the corresponding explosion-proof certification.
