Founded in 1894, it is an influential unofficial safety inspection institution in the United States, which mainly studies various materials, instruments, equipment, structures and systems related to the safety of life and property, and formulates corresponding standards. It signs agreements with manufacturers to test and track their products to determine whether these products pose a danger to users' lives and property. It authorizes manufacturers to use UL safety signs on products that have passed the inspection, and announces the results to insurance companies, government agencies and other organizations.

UL's safety signs are valued by the US government. The UL mark on products means that they have been tested and meet safety standards. Governments in many parts of the United States even stipulate that some imported products (especially electrical products) must be labeled with UL, otherwise the import, sale and use will be restricted. American consumers also trust UL very much, and products with UL logo have strong competitiveness in the United States, and the price can be increased accordingly.

UL has five testing laboratories in the United States and testing centers in 70 countries, and its testing representatives are all over the world. Many manufacturers have signed agreements with UL, requiring UL to carry out safety inspection on their products and affix the UL logo when exporting products.
