Unlisted (customized) component program

UL's Unlisted Component service is provided to end-product manufacturers, rather than component suppliers, for those situations where they have a customized component employed in a specific end-products that is not UL Certified.

Under this program, the component is evaluated in accordance with the applicable component requirements, taking into consideration the specific end-product application. The component is only evaluated for factory installation, not field installation. Once the component is found to be in compliance with the applicable component requirements, the component is placed under UL's follow-up surveillance program. Since the component is intended for a specific application, no information is published on UL's Online Certifications Directory or UL's directories.

Similar to UL's Component Recognition and Listing Service, the Unlisted Component Program creates value by increasing the confidence that the component complied with appropriate UL requirements when it was manufactured since it is under UL's Follow-up Program.
