Market Access in Mexico
In many countries, manufacturers, distributors, and importers of electronic or electrical equipment are required to demonstrate that their products meet the minimum safety requirements for both the end user and the environment they will be used. Each country’s market will require these products to meet their local standards and demonstrate compliance with these requirements before they can be sold in that market.
One such market that observes this practice is the Mexican market, which requires more than 2,000 classified products that be imported into the country to meet Norma Official Mexicana (NOM) standards. These products span across a variety of industries, but some sectors such as electrical equipment and electronics include additional mandatory requirements for energy efficiency.
With more than 100 million people in the Mexican market, manufacturers and importers must work to receive their NOM certification to sell their products to the market.
What is a NOM Certification?
Official Mexican Standards, or the Norma Official Mexicana (NOM) certification is a set of standards and legal enforcement documents that regulate the products, processes, and services that could pose a safety or health risk for people, animals, plants, or the environment. Most products imported, stored, transported, commercialized, sold, or used within Mexico must comply with these official Mexican standards, regardless of whether they have previously been certified to U.S., Canadian, or other international standards.
Testing can be conducted by a laboratory outside of Mexico, only if it holds a mutual recognition agreement, which has been approved by the Mexican General Directorate of Standards (DGN).
Scope & Compliance
NOM outlines the minimum safety requirements that an organization and its product, including the method of production, must meet. There are also requirements related to the packaging and materials such as commercial information and labeling that must also be observed. For electronics or electrical products, relevant energy efficiency standards may also be required.
NOM requirements for electrical and electronic products include:
All applicable products entering the Mexican market must be compliant with these regulations and receive a NOM mark, including exports that were once allowed into the country prior to these standards.
Steps for NOM Certification
The first step to the NOM certification process is for the manufacturer to complete an application, during which time the accredited laboratory will send a notification outlining any non-compliance issues that are uncovered. All issues of non-compliance or deficiencies must be addressed before the certification process can begin.
It’s important to work with an accredited Certified Body (CB) to fully understand the options for initial certification, follow-up inspections and testing, and future certification renewals.
Testing
Testing is an important element in the NOM certification process. Since there are requirements around the testing process that must be followed without any deviation or risk of being denied Certification, it’s crucial to use an approved and accredited Certification Body like Nemko to issue Certification.
Certification through a mutual recognition agreement (MRA) is possible and requires a validation and review process in addition to the other pieces of technical documentation.
Technical Documentation
These requirements vary by standard and may be specific to the third-party certification company that completes testing. However, it typically consists of the following:
Certification & Inspections
The correct form for obtaining a NOM certification must be used, as this is only granted by Certification Bodies that have been accredited by a Mexican Accreditation Entity, such as EMA, and approved by the Mexican General Directorate of Standards (DGN).
Nemko NOM certificates are valid for one year and are subject to audits during that period.
Products must be tested again during the mandatory follow-up inspections to ensure compliance throughout the certification cycle. The number and frequency of the audits are dependent on the standard but are typically conducted seven to nine months after initial certification. Follow-up visits are mandatory.
Although a NOM certification cannot be transferred, a certified holder can forward the usage rights to distributors within Mexico. Nemko refers to this as a “NOM Extension.” These parties can then receive a NOM certification of their own without additional testing required.
How Nemko Can Help
Nemko understands what it takes to comply with these Mexican standards and can help your company identify which NOM applies to your situation. Since the Mexican certification standards currently cover more than 2,000 products, it’s important to find out which NOM applies to your products specifically.
Nemko is accredited by the Mexican entity EMA and approved by the Mexican General Directorate of Standards to operate as a Certification Body, which means Nemko can certify products intended for the Mexican market.
