Product certifications based on Mexican Official Standards (NOM) and Mexican Standards (NMX)

UL is an independent organization with more than a century of experience in product safety and compliance evaluation, among which are product certifications based on Mexican Official Standards (Normas Oficiales Mexicanas – NOM) and Mexican Standards (Normas Mexicanas – NMX).

In August 2010,the Ministry of Economy published an executive order that recognized the equivalence of certain U.S. and Canadian issued certifications with those issued in accordance to the Mexican Official Standards by Mexican certification organizations.

Learn more about this order and UL’s response (Spanish content).

Conformity assessment determines the compliance degree with NOM, NMX and international standards. Also included, are other specifications, prescriptions, or features comprising product samples, tests, certification and surveillance (follow-up).

The decision to grant, maintain, extend, suspend, cancel or refuse a certification to a product is made based on sustainable technical foundations, the information gathered during the compliance evaluation process, results obtained during surveillance (follow-up) visits, and other relevant data.

The corresponding procedures* to grant, keep, extend, suspend, cancel or refuse a certification are available prior to issuing a written application to UL de México, S.A. de C.V. NOM program owner. Upon request a consultation will be performed by UL personnel.
