UL certification is a non-mandatory certification in the United States. It mainly tests and certifies product safety performance . Its certification scope does not include the EMC (electromagnetic compatibility) characteristics of the product. The main purpose of UL certification is to ensure that the product complies with relevant safety standards and regulations to protect the safety of consumers, workers and the environment.

The range of ul certified products is very wide, including electronic products, household appliances, lighting products, building materials, toys, auto parts, cosmetics, etc. After a product is UL certified, it can usually gain higher trust in the market, because UL certification is one of the internationally recognized product safety marks.

The testing and certification process of UL certification is very strict, including material analysis, performance testing, reliability testing, durability testing, environmental testing, etc. The certification standards are jointly formulated by UL's technical experts and industry experts, and they represent the highest level of global safety standards .

The UL certification mark is a UL logo, which means that the product has passed UL's testing and certification and meets UL's safety standards. UL certification is an international certification, and its mark is recognized and accepted in countries and regions including the United States, Canada, Europe, Asia, South America and the Middle East.

According to the different types of UL services, UL marks can be divided into three categories:

1. Listed. It is only used for complete products and various devices or equipment that are replaced or installed on site by qualified personnel. Products that fall under UL's listing service include: IT equipment, AV equipment, refrigerators, vacuum cleaners and other electrical equipment. If the final product needs to be marked with the UL listing mark, UL should test the sample to confirm that it has no hidden dangers of fire and electrical hazards.

2. Recognized. It is a safety certification mainly for components and materials. Recognized components will be assembled into finished products. Components must meet the relevant licensing conditions before they can be used in the corresponding finished products. For example, switches, power supplies, printed circuit boards, transformers, wires, plugs, and plastic materials are all recognized objects.

3. Classified. UL's classification service is a safety certification procedure that evaluates the hazards and other special performance of products used in commercial or industrial environments in accordance with relevant laws and regulations.
