Management System Registration Mark 
Database Record at

The UL Registered Firm Mark is a mark you will never see on a product. Instead, it indicates that a particular facility has passed UL's evaluation to management system standards and is used in promotion and marketing by companies with management system programs audited by UL. The standards UL uses are the ISO 9000 series of quality assurance standards; QS-9000 and TE Supplement, the quality standards developed by the big three U.S. automakers for their suppliers; ISO 14001, the standard covering environmental management systems, AS9000 for aerospace quality management systems, TL 9000 for telecommunications quality management systems and SA8000 for social accountability management systems.


C-UL US Listing Mark

UL introduced this new Listing Mark in early 1998. It indicates compliance with both Canadian and U.S. requirements. The Canada/U.S. UL Mark is optional. UL encourages those manufacturers with products certified for both countries to use this new, combined Mark, but they may continue using separate UL Marks for the United States and Canada.


Recognized Component Mark for Canada and the United States

This new UL Recognized Component Mark, which became effective April 1, 1998, may be used on components certified by UL to both Canadian and U.S. requirements. Although UL had not originally planned to introduce a combined Recognized Component Mark, the popularity of the Canada/U.S. Listing and Classification Marks among clients with UL certifications for both Canada and the United States has led to the new Mark.
