Intertek can help you obtain the NOM (Norma Oficial Mexicana) Mark approval for virtually any type of product exported into Mexico

All electrical products exported into Mexico must meet NOM requirements as well as mandatory energy efficiency requirements. If your product is in one of over 2,000 product categories, entering the Mexican market, you must have evidence of compliance with NOM standards. Products requiring NOM Certification include household refrigerators, freezers, gas heaters, cloth washers, air conditioners; small induction motors and motor operated tools; vertical and submersible water pumps; compact fluorescent lamps and wiring devices; telecom products that are data transmitters (digital, analogical, LAN or WAN systems) and those intended to be connected to the Public Telecom Network (PTN) and designed to process, receive, transmit or convert signals.

Intertek’s laboratory in Mexico City is an accredited EMA laboratory; however, you can receive testing from other Intertek labs in North America, Europe and Asia. Once the product is found to be in compliance with the applicable NOM requirements, a certificate is issued in favor of your Mexican representative, and the product can be marked with the Norma Oficial Mexicana (NOM) Mark.

Intertek has been accredited and approved as a Certification Body (Accreditation and Approval code: 61/08) by the General Direction of Standards (DGN) of the Secretaría de Economía in Mexico. As an accredited certification body, Intertek may test for product safety and issue the NOM Mark for Mexican market entry.

Under Mexican law, the Norma Oficial Mexicana (NOM) certificate holder, is responsible for warranty, maintenance and product liability. NOM certificates are non-transferable. However, a manufacturer that is a NOM holder may extend usage rights of its NOM certification to Mexican distributors, who may then obtain their own NOM certification without additional testing. NOM certificates will only be issued to Mexican manufacturers and exporters, or to manufacturers and exporters in countries with which Mexico has a free-trade agreement.
