Looking for information on UL Certified products?

If you specify products, inspect building construction or purchase products that must meet codes or Standards, you can find the information you need in UL's Product Directories. Architects, jurisdictional authorities, inspectors, product specifiers, designers, purchasing agents and others look to these publications to find important information about products bearing the UL Mark.

UL's Product Directories provide:

  • The names of companies whose product samples have been found to comply with the applicable safety requirements and are subject to UL's Follow-Up Services
  • Information pertaining to the form and nature of the appropriate Listing Mark, Classification or Recognition Marking to be used
  • Limitations or special conditions applying to a product
  • The title of the Standard used to investigate the product (if there is a published UL Standard or for international Directories an appropriate international or regional Standard) for the specific product category
