The UL Mark is the most widely recognized evidence of a product's compliance with U.S. safety requirements. To U.S. consumers, manufacturers, regulatory authorities and others, the UL Mark is the most familiar and trusted safety symbol. More than 19 billion UL Marks appear on new products every year.

Listing Service

UL's Listing service evaluates products for application of the widely recognized UL Certification Mark. The UL Listing Mark on a product tells that samples of that complete product have been tested by UL and found to be in compliance with the applicable UL requirements.

Classification Service

UL's Classification service evaluates industrial, commercial and other products for specific hazards and performance under limited conditions or regulatory codes. Products carrying this mark have been evaluated for a certain range of hazards or suitability for use under specific conditions. Typically, UL Classification service applies to building materials and industrial equipment.

Component Recognition Service

The UL Recognized Component Mark is used on components that are incomplete or restricted in performance capabilities, and intended for later use in a complete product or system Listed or Classified by UL. This mark is found on a wide range of products, including some switches, power supplies, printed wiring boards, some kinds of industrial control equipment and thousands of other products.

UL Recognized Components in any end product does not necessarily mean that the product itself is UL Listed or Classified.
