Reaching all North American markets in ONE step

Now it takes only one step - one set of samples and testing, working with one certification partner - to get all three certification marks and sell to

United States with the UL Mark
Canada with the cUL Mark
Mexico with the UL-MX NOM Mark

It means...

  • One testing process
  • Faster time to market
  • Saving sample shipment and testing costs

The UL-MX NOM Mark differentiates your products from the competition as it indicates your work with UL -- the certification organization that has earned an unquestioned recognition in safety and integrity.

The UL advantage

Expertise

UL is the first international third party organization authorized to issue the NOM Mark.  By working with UL, you leverage our expertise and network of Mexican certification.

Cost savings

In most cases, for products already with UL certification, we can issue NOM certification without additional sample or testing.  That means you enjoy big savings in sample shipment and testing expense.

Streamlined testing

Through the Test Data Exchange Agreements, UL can perform the NOM testing in its laboratories near you, with UL Mexico issuing the NOM Mark, making testing and mark issuance smoother and faster.

Differentiation

The quality and integrity of the UL certification process has earned the trust and respect from consumers, retailers, wholesalers and regulatory authorities all over the world.  The NOM Mark issued by UL will help you differentiate your products among your competitors.
