What is the Mexican NOM?

Normas Oficiales Mexicanas (NOM) is Mexico's mandatory safety mark, indicating that a product complies with the relevant NOM standards. The NOM mark applies to most products, including telecommunications and information technology equipment, household electrical appliances, lighting fixtures, and other products that pose potential health and safety hazards. Both domestically manufactured and imported products in Mexico must comply with the relevant NOM standards and product labeling regulations.

According to Mexican law, the holder of the nom certificate must be a Mexican company, responsible for the quality, maintenance, and reliability of the product. Test reports are issued by SECOFI-approved laboratories, reviewed 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, allowing the product to bear the NOM mark.

Mandatory Certification Modes:

- M0: Certification through quality control and regular testing verification.

- M1: Certification through regular testing verification (new product type testing).

- M2: Certification through quality system evaluation (new products).

- M3: Certification through regular test verification, issuing a letter of conformity (for new products).

- M4: Certification through quality control and regular testing verification (for redesigned products).

- M5: Batch certification (for redesigned products without a redesign manual and second-hand products).

- M6: 100% certification (for non-standard products).

The certificate holder is usually an individual importer, manufacturer, or distributor. Foreign manufacturers can apply for certification through certification bodies recognized by the Mexican Standardization Committee.
