The UL advantage

Market acceptance -- No other compliance mark speaks with more authority and integrity among North American regulators, consumers and retailers, giving products the surest route to market acceptance.

  • Regulators -- A recent study revealed that, as compared to the other compliance marks, regulators are much more likely to immediately accept the UL Mark without further steps or information.
  • Consumers -- Recognition and acceptance of the UL Mark by consumers helps manufacturers establish instant credibility and differentiate themselves from products that are not UL Listed. In a recent study, the majority of consumers were more confident of a product's safety if it carried a UL Mark. Other certifiers do not inspire as much confidence by consumers.
  • Retailers -- UL has a dedicated team of retail account managers responsible for building retail preference for products carrying the UL Mark.

Knowledge of standards -- Customers gain access to unmatched breadth and depth of expertise from UL, the leader in developing and interpreting standards.

Technical expertise -- UL engineers are experts in the complex technology of alarm systems. UL has primary designated engineers (PDEs) dedicated to fire and life safety alarms.

Complete compliance solutions provider -- UL provides the most comprehensive suite of compliance solutions and the most sophisticated testing resources under one umbrella organization.
