Underwriters Laboratories Inc. (UL) is an independent product safety certification organization. Established in 1894, the company has its headquarters in Northbrook, Illinois. UL develops standards and test procedures for products, materials, components, assemblies, tools and equipment, chiefly dealing with product safety. UL also evaluates and certifies the efficiency of a company's business processes through its management system registration programs. Additionally, UL analyzes drinking and other clean water samples through its drinking water laboratory in South Bend, Indiana and evaluates products for environmental sustainability through its subsidiary, UL Environment.

There are many types of UL Marks, each with its own specific meaning. The only way to determine if a product has been certified by Underwriters Laboratories® is to look for the UL Mark on the product itself. In a few instances, the UL Mark may be present only on the packaging of a product.

Some products certified by UL are components that are intended to be used in the manufacture of a complete Listed product. These components cannot bear the UL symbol, but may use a special Recognized Component Mark.

The UL Mark on a product means that UL has tested and evaluated representative samples of that product and determined that they meet UL requirements. Under a variety of programs products are periodically checked by UL at the manufacturing facility to make sure they continue to meet UL requirements. The UL Marks may be only used on or in connection with products certified by UL and under the terms of written agreement with UL. In addition to these marks, UL also provides access to the marks required in a number of other key world markets.
