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.
Do import explosion-proof electrical equipment need to obtain the CCC certification?
The CCC certification is a mandatory product certification in China, which means that all explosion-proof electrical equipment listed in the CCC product catalog must obtain a CCC certification certificate.
Imported products that are listed in the CCC catalog and are for sale must also obtain a CCC certification.
The process for applying for the防爆 CCC certification for imported explosion-proof electrical equipment is essentially the same as for domestically produced products.
All must undergo application, type testing, and factory audit. If the factory is overseas, an audit must also be conducted abroad.

Requirements for applying for the explosion-proof 3C certification:
Certificate Application Form
(2) Certified Principal, Manufacturer, and Manufacturer's Registration
(3) Product Description, which includes: technical specifications, structure, model descriptions, list of key components and materials, as well as explanations of differences between products of various specifications within the same certification unit;
(4) Technical documents, mainly including: product standards (or technical specifications), manuals, product drawings related to explosion-proof performance, etc.
(5) Certificate of Compliance for test samples, Factory Testing Report, etc.
(6) Manufacturer Information Sheet (for factory inspection)
(7) ODM Model: Provide the relevant documents as required by the supplementary regulations of CQM02-C1 "Supplementary Regulations for ODM Model in CCC Certification," such as the ODM agreement.
(8) OEM Model: OEM agreements, etc.
(9) Documentation for relevant change projects on change applications;
(10) Any other required documents.
