Significance of CQC Mark Certification

Upon obtaining CQC Mark Certification, enterprises are permitted to affix the CQC mark to certified products. The mark indicates that products meet relevant certification requirements for quality, safety, performance, electromagnetic compatibility and other aspects, delivering reliable products for end‑users.

 

CQC Mark Certification brings the following benefits for enterprises:

1. Build brand image, improve market competitiveness, obtain a “green pass” for market access, increase market share, and help enterprises achieve both economic and social benefits.
2. Product cost control: Widely recognized and adopted across industries, CQC product certification effectively avoids duplicate testing and certification, and reduces operating costs.
3. Support sustainable enterprise development: CQC product certification encourages enterprises to enhance factory quality assurance capability, establish modern enterprise management systems, and support long‑term corporate growth.
