With branches both at home and abroad, CQC is the earliest and most authoritative certification body in China for quality certification work. Its main businesses include: undertaking the national mandatory product certification (CCC) work authorized by the government, covering over one hundred types of products such as product safety, performance, environmental protection, organic products, and more.
CQC Mark Certification is one of the voluntary product certification services offered by China Quality Certification Centre. It indicates that the product meets relevant certification requirements in terms of quality, safety, performance, electromagnetic compatibility, etc., by applying the CQC mark. The scope of certification covers more than 500 types of products, including mechanical equipment, electrical equipment, electrical appliances, electronic products, textiles, building materials, and more. CQC Mark Certification focuses on indicators that directly reflect product quality and affect the personal and property safety of consumers, such as safety, electromagnetic compatibility, performance, and limits of harmful substances (RoHS). Its aim is to safeguard consumer interests, promote product quality improvement, and enhance the international competitiveness of domestic enterprises.
