The NOM mark is a mandatory safety mark in Mexico to indicate that the product complies with the relevant NOM standards. The NOM logo applies to most products, including telecommunications and information technology equipment, household electrical appliances, lamps and other products that are potentially hazardous to health and safety. Whether it is locally manufactured or imported in Mexico, it must comply with the relevant NOM standards and product labeling regulations.

The Normas Oficiales Mexicanas sign is a mandatory safety sign in Mexico to indicate that the product complies with the relevant NOM standards. The NOM logo applies to most products, including telecommunications and information technology equipment, household electrical appliances, lamps and other products that are potentially hazardous to health and safety. Whether it is locally manufactured or imported in Mexico, it must comply with the relevant NOM standards and product labeling regulations.

Under 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 reviewed by SECOFI, ANCE or NYCE. If the product meets the relevant regulatory requirements, a certificate will be issued to the Mexican representative of the manufacturer or exporter, and the product can be marked with the NOM mark.

Mandatory Authentication Mode

- M0: certification by quality control and periodic test verification;
- M1: certification by periodic test verification (new product type experiment);
- M2: certification by quality system evaluation and verification (new product);
- M3: Letter of conformity issued by periodic test verification (for new products);
- M4: Certification by quality control and periodic test verification (for redesigned products);
- M5: Batch certification (Applicable to redesigned products and used products without redesign manual);
- M6: 100% certification (applicable to non-standard products).
The certificate holder is usually a separate importer, manufacturer and distributor, and foreign manufacturers can apply for a certificate through a certification body recognized by the Mexican Standardization Committee.

NOM certification lead time

4-6 weeks

Mexico only recognizes its own NOM safety signs, and the safety signs of the United States and Canada (such as CUL, ETL, CSA) are not recognized by the government of that country. Products requiring compulsory certification can enter the Mexican market only with the NOM safety mark.
Normally, the NOM logo often appears together with NYCE or ANCE:
——NOM NYCE: applicable to electronic products, communication products and data processing equipment, but excluding household appliances;
——NOM ANCE: applicable to household electrical appliances, including household electrical appliances, Electric hand tools, etc.
