Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof CCC certification. 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 imported explosion-proof electrical equipment need to apply for the CCC certification?
The CCC certification is a mandatory product certification in China, meaning 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, a factory audit must also be conducted abroad.

Basic contents of factory audit for explosion-proof CCC certification:
A. Factory inspection conclusions are typically categorized into four types: "Factory Inspection Passed," "Written Verification Passed," "On-Site Verification Passed," and "Factory Inspection Failed."
"Written Verification Passed" refers to the case where there are non-conformities, the factory takes corrective actions within the specified time frame, and the certification body validates the written verification as effective, resulting in the factory passing the inspection; "On-site Verification Passed" indicates that there are non-conformities, the factory implements corrective measures within the designated period, and upon the certification body's on-site validation being deemed effective, the factory passes the inspection.
B. Factory audits typically require corrections to be completed within 40 days of any non-compliance issues.
C. Basic Review Items
(1) Specify whether the test results are satisfactory.
(2) Do the key resources meet the requirements for ensuring product consistency or compliance with standards?
(3) Product consistency issues, such as changes in product structure or critical components, are they in compliance with the specified requirements?
(4) Determine if the certified products have defects that could lead to quality safety incidents.
(5) Is the effective implementation of product certification changes and consistency control in place?
(6) Did the factory take corrective actions during the certification certificate suspension period?
(7) Proper use of the CCC mark or certificate, including alteration, rental, lending, misuse, sale, transfer, and theft of the CCC mark or certificate; continuing to use the CCC mark or certificate after being notified of its revocation or suspension; intentionally affixing the CCC mark to products without obtaining the CCC certificate; other cases of intentional illegal use of the CCC mark or certificate.
(8) Does the factory have any instances of obtaining certification certificates through fraudulent or corrupt means?
(9) Are there any other situations that directly threaten product consistency or compliance with standards?

Are explosion-proof certification and explosion-proof compliance certificates the same?
Many clients ask what the difference is between obtaining a flame-proof certification and a flame-proof qualification certificate when inquiring about products.
Explosion-proof certification and explosion-proof compliance certificate are two distinct concepts.
The product has passed the explosion-proof certification, and the final outcome is the explosion-proof certificate.
Explosion-proof certification is the process, and the explosion-proof certificate is the result.
So the customer mentioned the product needs to be certified for explosion-proof or obtain an explosion-proof certificate.
The product must pass the explosion-proof standard tests and meet the requirements to obtain the explosion-proof certification.
Explosion-proof certifications can be categorized into intrinsic safety type, flameproof type, positive pressure type, and encased type, among other explosion-proof protection styles.
ZhongNuo Inspection boasts a team of explosion-proof engineers who can provide initial design services for explosion-proof circuits and structures.
Assist companies in preparing the required drawings, technical specifications, and documentation, including corporate standards, for explosion-proof certification, facilitating their easy acquisition of the explosion-proof compliance certificate.
