Extended information:
UL marks are divided into three categories, namely, listing, grading and approval marks. The main components of these marks are UL patterns, and they are all registered trademarks. It is not universal to apply them to different service products.
the fact that a company is approved by UL does not mean that all products of the company are UL products. Only products with UL logo can be considered as products produced under UL tracking inspection service. UL distinguishes UL products by using column names, grades and approval marks used on products or related products (see figure). UL's services are not only based on the UL standard of the United States, but also based on the UL safety certification of Canada. There are three types: the classification standard of authorized listing. UL stipulates that before January 28, products that have been listed or approved by both UL and CUL can be labeled with UL and CUL at the same time. After 28, new marks will be used.

UL features
it is mainly used in general end products that consumers can buy directly from the market, such as household appliances, computers, heaters, fuses, power boards, smoke detectors, fire extinguishers and other products.

batteries often have to pass UL certification before entering the American market. Although UL certification is voluntary, the United States Customs releases goods with the "UL" logo, but without this logo, it needs complicated inspection procedures. And when a safety accident occurs, the Fire Safety Committee (CPSC) will also take the UL standard as the basis for judgment. Therefore, in the United States, many sellers refuse to sell goods without the "UL" logo in order to avoid trouble.

Whether products produced by enterprises within the EU or products produced by other countries want to circulate freely in the EU market, it is necessary to affix the "CE" mark to show that the products meet the basic requirements of the EU Directive on New Methods of Technical Coordination and Standardization. This is a mandatory requirement for products in EU law.
