Electrical and electronic goods are tightly regulated products in Mexico. If you plan to import or sell this kind of product there, compliance is not something you can leave until the last minute. One of the frameworks is NOM. Below is a practical overview of what the NOM mark is, which products may fall within scope, how the process works, and what importers should check before shipping to Mexico.
What is the NOM mark?
NOM stands for Norma Oficial Mexicana, which is the system of official Mexican technical regulations. In practical terms, the NOM mark shows that a product has been evaluated against the applicable Mexican standard for its category.
For electrical and electronic products, NOM requirements commonly relate to three areas:
- electrical safety, including protection against fire, electric shock, and physical hazards;
- energy efficiency, where an applicable NOM-ENER standard exists;
- commercial information and labeling, including Spanish-language documentation and product information where required.
For some products, especially wireless or telecom-capable equipment, NOM compliance is only part of the picture. Separate Mexican telecom approval may also be required.
Important: A CE mark, UL mark, or FCC authorization does not replace Mexican compliance requirements. Even if a product already meets US or EU requirements, that does not automatically make it compliant for sale or import in Mexico.
Who issues NOM certification?
NOM certification is not issued directly by a foreign lab or by a private company acting on its own. In Mexico, product conformity assessment is handled through certification bodies and laboratories that operate within the official Mexican conformity-assessment framework.
In practice, importers most often work with recognized certification bodies such as ANCE or NYCE, depending on the product category. Testing is normally carried out by a properly accredited laboratory, and the certification process is linked to the applicable NOM standard and the current Mexican import rules.
It is also common for the certificate and import documentation to be tied to a Mexican importer or local entity involved in the product’s entry into the Mexican market. Because of that, foreign manufacturers usually need to coordinate closely with their Mexican importer, distributor, or local representative.
Which products may require NOM compliance?
The scope is broad. Many electrical and electronic products imported into Mexico are subject to mandatory compliance with one or more NOM standards, especially where product safety or labeling is concerned. Common examples include:
- household electrical appliances, such as microwaves, washing machines, refrigerators, and water heaters;
- consumer electronics, including televisions, speakers, audio equipment, and certain accessories;
- IT and office equipment, such as computers, peripherals, and some networking products;
- lighting products, including lamps and luminaires;
- power accessories, such as adapters, chargers, switches, plugs, and cable assemblies;
- wireless and telecom-capable products, where both safety and telecom approval may apply.
The exact requirement always depends on the product’s design, function, voltage, tariff classification, and the specific standard that applies. That is why it is risky to assume a product is exempt simply because it looks low-risk or because it already complies in another country.
Key NOM standards for electrical and electronic products
Identifying the right standard is the first real step in the process. A single product may fall under more than one requirement.
NOM-001-SCFI-2018
This is one of the main safety standards for electronic equipment. It applies to a wide range of electronic products and is focused on reducing risks such as fire, electric shock, and injury during use.
NOM-003-SCFI-2014
This standard is widely used for electrical products and household electrical items. It covers safety specifications for a broad group of electrical products placed on the Mexican market.
NOM-019-SCFI-1998
This standard has long been associated with certain data processing and information technology equipment. Depending on the product, it may still be relevant in practice, especially where older certification pathways or customs criteria still reference it.
NOM-024-SCFI-2013
This is especially important and often underestimated. It covers commercial information for packaging, manuals, and warranties of electronic, electrical, and household electrical products. In practical terms, this usually means that instructions, warranty information, and other required consumer information must be available in Spanish and presented correctly.
NOM-ENER standards
For some appliances and lighting products, a separate energy-efficiency standard may also apply. These standards are issued within the NOM-ENER family and can require minimum performance levels, test methods, labeling, or energy-related product information.
How to get NOM certification
The process varies depending on the product and the standard involved, but the overall structure is usually similar.
Step 1 – Identify the applicable NOM standard
Start with the product’s technical characteristics and tariff classification. The same product family may trigger different requirements depending on voltage, use, or function. This is the stage where importers often save time by consulting a certification body early.
Step 2 – Define the Mexican entity involved in importation
In practice, the importer or another local Mexican entity often plays a central role in the certification and import process. Before moving forward, it is important to confirm who will appear in the documentation and who will be responsible for the product in Mexico.
Step 3 – Prepare the technical and labeling file
This usually includes product specifications, manuals, model lists, labeling artwork, and supporting technical documents. For many products, Spanish-language documentation is essential.
Step 4 – Arrange testing and conformity assessment
The product is then evaluated according to the applicable NOM standard through the relevant conformity-assessment route. Depending on the product and the certification body, local testing or review of supporting documentation may be required.
Step 5 – Obtain the certificate or conformity document
Once the product meets the applicable requirements, the certification body can issue the corresponding conformity document. At that point, the importer can align labeling, import documentation, and shipment planning with the certified models.
Step 6 – Keep the certification current
Certification is not something to forget once the first shipment clears. Product changes, labeling updates, model additions, or certificate expiry can all create new compliance issues later. Importers should treat NOM compliance as an ongoing obligation, not a one-time formality.
How long does NOM certification take?
There is no single timeline that applies to every product, but in practice importers should not treat NOM certification as something that can be arranged at the last minute. A straightforward product may move faster if the documentation is complete and the certification path is clear. More complex products, products requiring testing, or products needing parallel approvals can take substantially longer.
As a practical rule, it is safer to begin the process well before the planned ship date rather than assume it can be solved once the goods are already in transit.
Important: If NOM-related compliance is required for your product, trying to “fix it later” after the shipment has already left origin is one of the fastest ways to create delays, storage costs, and customs problems.
How long is NOM certification valid?
Validity depends on the product, the certification route, and the certification body involved. In practice, importers should always confirm the validity period and any surveillance or renewal requirements directly with the body handling their file.
Keep in mind that expired or incomplete certification can affect both import clearance and legal sale in Mexico. That is why certificate management matters just as much as initial certification.
What happens if you do not have NOM compliance?
If your product requires NOM compliance and you do not have it in place, the consequences can be serious. Depending on the product and the stage of importation or sale, this may include customs delays, refusal of clearance, additional inspections, fines, product withdrawal, or commercial rejection by distributors and retailers.
Even where the product itself is technically safe, missing Spanish labeling, inconsistent model numbers, or incomplete documentation can still create costly problems.
NOM compliance and your shipment to Mexico
Certification is only one side of the process. The other is making sure the shipment documents match the approved product details. Your commercial invoice, packing list, labeling, and model references should be fully consistent with the product as certified. In practice, even small differences in model suffixes, voltage references, or product descriptions can trigger questions at customs or during market checks.
That is why working with a freight forwarder who understands Mexico’s import compliance environment can make a real difference. A forwarder with experience in the Mexican market can help you align documentation, identify obvious mismatches before shipment, and reduce the risk of avoidable delays.

Frequently asked questions
Can I use FCC or CE certification instead of NOM?
Foreign certifications may help from a technical or documentation perspective, but they do not replace Mexican compliance requirements where NOM or other Mexican approvals are mandatory.
Does NOM certification cover both safety and energy efficiency?
Not always under one single standard. Depending on the product, separate NOM requirements may apply for safety, commercial information, and energy efficiency.
What if I change the product after certification?
If the change affects safety, labeling, technical characteristics, or model identity, you should assume the compliance file may need to be reviewed again. Always confirm that with the certification body before shipping modified products.
