What is CQC certification? CQC certification is one of the voluntary product certification services carried out by the China Quality Certification Center. By adding the CQC logo, it indicates that the product meets the relevant quality, safety, performance, electromagnetic compatibility and other certification requirements. The certification scope covers more than 500 products such as mechanical equipment, power equipment, electrical appliances, electronic products, textiles, building materials, etc. The CQC logo certification focuses on indicators that directly reflect product quality and affect consumers' personal and property safety, such as safety, electromagnetic compatibility, performance, and harmful substance limits （RoHS）， with the aim of safeguarding consumer interests, promoting the improvement of product quality, and enhancing the international competitiveness of domestic enterprises.

　　What is 3C certification? In December 2001, the General Administration of Quality Supervision, Inspection and Quarantine of China issued the "Regulations on the Management of Compulsory Product Certification", replacing the original import commodity safety and quality licensing system and electrical product safety certification system with the compulsory product certification system. China Compulsory Certification, abbreviated as CCC certification or 3C certification. It is a statutory mandatory safety certification system and a basic practice widely adopted internationally to protect consumer rights and safeguard consumer personal and property safety.

　　The products listed in the "Catalogue of Products Subject to Compulsory Product Certification" include household appliances, automobiles, safety glass, wires and cables, toys, and other products.

　　Is it necessary to obtain CQC certification or 3C certification for terminals?

　　Generally speaking, terminal blocks are not within the scope of CCC certification, and terminal blocks need to undergo CQC certification to demonstrate that the terminal product meets relevant certification requirements for quality, safety, performance, electromagnetic compatibility, etc!

　　That is to say, products within the scope of CCC certification must undergo CCC certification, while those outside the scope can voluntarily undergo CQC certification for better recognition and sales.
