In the USA and Canada, virtually all electrical products must undergo some form of conformity assessment (testing, inspection, product certification) so that acceptance interests (federal, state, and local regulating authorities; retailers; distributers; consumers, etc.) have confidence that the product meets relevant safety and other requirements.

OSHA is the U.S. federal regulating authority for U.S. workplace environments. OSHA demands product safety certification for some (not all) of the workplace products that come under the scope of its regulations. OSHA only requires certification for end products. In order for these product certifications to fulfill OSHA regulatory requirements the certifications must be issued by a Nationally Recognized Testing Laboratory (NRTL) (like UL) formally recognized by OSHA.


The UL (US) and cUL (Canada) Marks are two of the most commonly recognized and accepted NRTLs certification marks in North America. They “set the standard” and are regularly accepted by authorities having jurisdiction, inspectors and others. They provide a strategic marketing advantage to our customers who value quality and integrity.

In addition to traditional NRTL certification services, UL offers a straight-forward way to convert from another NRTL certification mark to UL. It is as simple as giving UL your current test report (including test data), a sample and your risk management file (if applicable). UL expert engineers will review the data for scope, potentially conduct test checks and if all is in compliance with the appropriate standard, UL will transfer your file and you can start to place the UL Certification Mark on your product immediately.
