NOM certification

The NOM (Normas Oficiales Mexicanas) logo is a mandatory safety symbol for Mexico to indicate that the product complies with the relevant NOM standards.

The difference between NOM logo and NMX logo

First: different procedures are required

The NOM (Normas Oficiales Mexicanas) logo is a mandatory safety symbol for Mexico to indicate that the product complies with the relevant NOM standards. The NMX (Normas Mexicanas) standard is voluntary.

Second: the corresponding product is different

The NOM logo is suitable for most products, including telecommunications and information technology equipment, household electrical appliances, lamps and other products that are potentially hazardous to health and safety. Products manufactured or imported locally in Mexico are subject to relevant NOM standards and product labeling requirements. NMX is generally suitable for parts such as conductors, fuses, circuit breakers, lamp holders and ballasts for manufacturers' reference; but when a NMX is required to become a reference for the NOM standard, the NMX requirement becomes mandatory. standard.
