NOM certification

The NOM (Normas Oficiales Mexicanas) mark is a mandatory safety mark in Mexico, used to indicate that a product complies with relevant NOM standards. The NOM logo is applicable to most products, including telecommunications and information technology equipment, household electrical appliances, lighting fixtures, and other products that pose potential risks to health and safety. Both locally manufactured and imported products in Mexico must comply with relevant NOM standards and product labeling regulations.

According to Mexican law, the licensee of NOM must be a Mexican company responsible for the quality, maintenance, and reliability of the product. The test report is issued by a laboratory accredited by SECOFI and audited by SECOFI, ANCE or NYCE. If the product meets the relevant regulatory requirements, a certificate is issued to the Mexican representative of the manufacturer or exporter before the product can be marked with the NOM logo.

The difference between NOM logo and NMX logo

Firstly, different programs are required

The NOM (Normas Oficiales Mexicanas) mark is a mandatory safety mark in Mexico, used to indicate that a product complies with relevant NOM standards. The NMX (Normas Mexicanas) standard is voluntary.

Secondly, the corresponding products are different

The NOM logo is applicable to most products, including telecommunications and information technology equipment, household electrical appliances, lighting fixtures, and other products that pose potential risks to health and safety. Both locally manufactured and imported products in Mexico must comply with relevant NOM standards and product labeling regulations. NMX is widely used for components such as conductors, fuses, circuit breakers, lamp holders, and ballasts, and is provided as a reference for manufacturers; But when a certain NMX requirement becomes a reference regulation for NOM standards, the NMX requirement becomes a mandatory standard.
