Overview of the five major national and regional certification standards

Japan: Compulsory market access system for Japanese electrical appliances. "Specified electrical appliances" must be certified by a third-party certification agency authorized by the Ministry of Economy, Trade and Industry of Japan, obtain a certification certificate, and be affixed with a diamond-shaped PSE mark; before being sold in the Japanese market, non-specific electrical appliances must undergo self-testing and self-declaration to confirm that they meet the technical standards of Japanese electrical appliances, and be affixed with a round PSE mark. North America: UL certification is a product safety certification performed by Underwriters Laboratories, a private safety testing agency in the United States. Generally speaking, UL standards can be divided into: requirements for product structure, requirements for raw materials used in products, requirements for components used in products, requirements for test instruments and test methods, requirements for product markings and instructions, etc. Now UL certification has become one of the most stringent certifications in the world. European Union: The CE certification mark is a safety certification mark that is regarded as a passport for manufacturers to open and enter the European market. All products bearing the CE mark can be sold in each EU member state without having to meet the requirements of each member state, thus achieving the free circulation of goods within the EU member states. China: The 3C certification mark is a certification mark that the products in the "Catalogue" are allowed to be sold, imported and used. It indicates that the safety, electromagnetic compatibility and electromagnetic radiation of the product comply with national standards. All products sold in the Chinese market that are subject to compulsory certification must be forced to pass this certification. International: CB certification is a certification system developed by IECEE (International Electrotechnical Commission Electrical Product Safety Certification Organization), which mainly targets 14 categories of products such as wires and cables, electrical switches, and household appliances. The CB system is a global mutual recognition system for electrical products established by IECEE. Having the CB mark means that the manufacturer's electronic products have passed the testing of NCB (international certification body).
