Mexico Customs NOM Certificate

What is a NOM Certificate?

The NOM (Normas Oficiales Mexicanas) mark is a mandatory safety mark in Mexico, indicating that a product complies with relevant NOM standards. The NOM mark applies to most products, including telecommunications and information technology equipment, household electrical appliances, lighting fixtures, and other products with potential health and safety risks. Products manufactured locally in Mexico or imported must comply with the relevant NOM standards and labeling requirements. The NOM certification primarily addresses safety requirements.

According to Mexican law, the NOM certificate holder must be a Mexican company responsible for the product's quality, maintenance, and reliability. Test reports are issued by SECOFIaccredited laboratories and 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.

Types of NOM Verification Units

 NOM NYCE: Verification scope includes all electronic and information products and data processing equipment, except household appliances (excluding microwave ovens).

 NOM ANCE: Verification scope includes all electrical and similar products (such as household appliances).

   Not applicable to IEC standards, applicable to NOM standards.

   No EMC testing required.

NOM Technical Information

 Mexican voltage is 127V/60Hz.

 Plugs are the same as US plugs. There are two types: Class I with three connectors and Class II with two connectors. Plugs will be tested along with the equipment.

NOM Certificate Issuance

 The certificate is valid for one year and can be renewed annually.

 To renew the certificate, one product must be randomly sampled from the market and sent to a laboratory for testing.

 Product packaging must include the following information: product name, brand name, model, and NOM verification mark.

NOM Certification Document Requirements

 CB test report and certificate.

 Name, address, and contact person of the importer or distributor in Mexico.

 Test data, design drawings, specifications, and circuit diagrams.

 Spanish labels.

 Original Spanish user manual.

 A sample and additional documents from the importer or distributor.

One to three test samples are required, depending on the product.

NOM Certification Review Time

Once all documents are submitted, the review process takes 56 weeks. After the NOM application is completed, the original certificate and report will be sent to the local agent in Mexico, and the applicant company will receive a fax copy. The agent must properly keep the original certificate and report for future reference and inspection.

Mutual Recognition of North American Certification

On August 17, 2010, the Mexican government published a new resolution in the Official Gazette confirming the equivalence between three NOM standards in Mexico and the corresponding standards in the United States and Canada. Therefore, for the following electrical and electronic products imported into Mexico, applying for a North American certification mark (such as UL, CSA, ETL, MET) is sufficient to enter the Mexican market without needing NOM certification.
