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 before the product can be marked with the NOM mark.

Mandatory Authentication Mode：

• M0: Certification through quality control and periodic test verification;

• M1: Certification by Periodic Test Verification (New Product Type Experiment);

• M2: Certification by Quality System Assessment Verification (New Product);

• M3: Letter of Conformity issued by periodic test verification (for new products);

• M4: Certification through quality control and periodic test verification (for redesigned products);

• M5: Batch Certification (for re-engineered and second-hand products without a re-engineering manual);

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

Applicable Product Range:

Products subject to NOM compulsory certification are generally electrical and electronic products with a voltage exceeding 24 volts of alternating current or direct current. Mainly used in the fields of product safety, energy and heat effects, installation, health and agriculture. The following products must be NOM certified to be allowed into the Mexican market:

1. Electronic or electrical products for home, office and factory use;

2. Computer LAN equipment;

3. Lighting device;

4. Tires, toys and school supplies;

5. Medical equipment;

6. Wired and wireless communication products, such as wired telephones, wireless telephones, etc.;

7. Products powered by electricity, propane, natural gas or batteries.

Packaging Label Information:

1. The name and address of the importer or distributor

2. NOM logo

3. original domestic information

4. Rated value of product input/output

5. Product name and model

6. Packing quantity

Mexico only recognizes its own NOM safety signs, and the safety signs of the United States and Canada are not recognized by the government of that country. Products requiring compulsory certification can enter the Mexican market only with the NOM safety mark.

Typically, the NOM logo appears with NYCE or ANCE:

• NOM NYCE: applies to electronic products, communication products and data processing equipment, but does not include home appliances;

• NOM ANCE: Applicable to home appliances, including household electric instruments, electric hand-held tools, etc.
