What Is NOM Certification for Mexico?
Mexico, along with the United States and Canada, is one of the three member countries of the North American Free Trade Agreement (T-MEC). As such, it is a strategic – and lucrative – gateway for producers wishing to market their products and goods in this vast trade zone.
All products sold in Mexico must comply with Official Mexican Standards, or Norma Oficial Mexicana (NOMs), which are Mexico’s primary, mandatory standards established in the National System of Quality Infrastructure. In this article, we delve into the world of NOMs, exploring their significance and the NOM certification process. You’ll learn how to secure your business activities in Mexico and how NOMs safeguard consumer interests in Mexico’s marketplace.
What is NOM Certification?
NOMs are standards that encompass a diverse range of industries, including electronics, automotive, food and beverages, and environmental protection. Compliance with NOMs is mandatory for manufacturers, importers, and distributors who wish to enter the Mexican market or operate within its borders.
NOMs are a key pillar of the country's regulatory framework. These standards are developed and approved by several agencies of the Mexican federal government, and they establish specific, mandatory requirements and procedures aimed at guaranteeing both the quality and safety products with regard to consumers and the environment.
NOMs may include requirements for a product’s design, method of production, or operation, as well as requirements related to symbology, packaging, or labeling.
Which Products Require NOM Certification?
There are over 2000 product categories that require NOM certification in Mexico. Products that require NOM certification include, but are not limited to:
Electrical appliances: Household devices, lighting equipment, and electronic components
Automotive products: Vehicles, tires, and automotive spare parts
Health and safety-related items: Pharmaceuticals, medical devices, and personal protective equipment (PPE).
Consumer goods: Textiles, toys, and furniture.
Food and beverages: Processed foods, beverages, and food additives
Telecommunications equipment: Devices and infrastructure related to communication technology

NOM Certification Conformity Assessment Process
Companies must demonstrate the compliance of products and goods with a given Official Mexican Standard prior to their import to Mexico and sale in the Mexican market. This is where NOM certification comes in.
In order to comply and secure NOM certification, companies must ensure that they can produce official documents demonstrating that their goods and products meet the requirements and specifications described by the authorities.
It is recommended that applicants work with duly accredited and approved certification agencies to perform the conformity assessment process for NOM certification.
NOM Certification Process: 5 Steps at a Glance
1. Identify applicable NOMs. Find the relevant NOMs for your product. Work with the support of an external expert or by consulting the Official Mexican Standards database on the website of the Mexican Secretariat of Economy.
2. Gather product documentation. Up-to-date product documentation is essential, including technical specifications, test reports, and labeling information. This documentation will be used to assess your product's compliance with the applicable NOM requirements.
3. Laboratory testing. Your product must be tested in an accredited laboratory in Mexico or one located outside of Mexico that has a Mutual Recognition Agreement (MRA) approved by the General Directorate of Standards (DGN) of the Mexican Secretariat of the Economy. NYCE, a QIMA company, is an accredited laboratory in Mexico with an MRA with certifying bodies outside Mexico.
4. Obtaining a NOM certificate: Once your product has passed testing you'll receive a test report which means you can apply for a NOM certificate from a certification body (CB) like NYCE that has been approved and accredited by Mexican authorities. The CB will review your product documentation and test results and issue a NOM certificate if your product meets the requirements of the applicable NOMs.
5. Marking your product with the NOM mark: Once you've obtained a NOM certificate, you can mark your product with the NOM mark. The NOM mark is a visual indicator that your product meets the requirements of the applicable NOMs. A NOM mark on your product means you'll have access to the Mexican market for seamless importation, transportation, and/or commercialization.
The NOM certification process can be complex and time-consuming, but it is essential for ensuring that your products meet the requirements of the Mexican market. By following the steps outlined above and working with an approved certification body like NYCE, you can ensure that your products are properly certified and that you can enter the Mexican market without any problems.
