Update time : 2024-10-17

Introduction to NOM

Normas Oficiales Mexicanas (NOM) is Mexico's mandatory safety mark, indicating that products comply with relevant NOM standards. The NOM mark applies to most products, including telecommunications and information technology equipment, household electrical appliances, lighting, and other products that pose potential risks to health and safety. Both locally manufactured and imported products must meet NOM standards and labeling requirements.

According to Mexican law, the NOM certificate holder must be a Mexican company, responsible for product quality, maintenance, and reliability. Test reports are issued by SECOFI-approved laboratories and reviewed by SECOFI, ANCE, or NYCE. If the product complies with relevant regulations, a certificate will be issued to the manufacturer or exporter’s representative in Mexico, allowing the product to carry the NOM mark.

 

The NOM mark is often seen together with NYCE or ANCE:

- NOM NYCE: For electronic products, communication products, and data processing equipment (excluding household appliances).

- NOM ANCE: For household appliances, including home electric tools and handheld power tools.

 

Common Issues Explained

- Mexico's voltage is 127V/60Hz.

- The plugs are the same as those used in the US: Class I with three pins and Class II with two pins. Plugs are tested with the equipment.

- Certificates are valid for one year and can be renewed annually.

- When renewing certificates, a product sample must be randomly taken from the market for testing.

- Packaging must include the following information: product name, brand, model, and NOM mark.

 

Certification Program Details

There are 7 mandatory certification models:

- M0: Certification through quality control and periodic testing.

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

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

- M3: Certificate of conformity issued through periodic testing (for new products).

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

- M5: Batch certification (for redesigned or second-hand products without redesign manuals).

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

 

Certification Scope

NOM mandatory certification generally covers electronic and electrical products with an AC or DC voltage exceeding 24 volts. It mainly applies to safety, energy, thermal effects, installation, health, and agriculture. The following products must obtain nom certification to enter the Mexican market:
