Planning to sell stuff in Mexico? Then ya gotta kno about NOM Certification.
Welle Inspection brings you this no-nonsense guide to help ya understand Mexico NOM standards and how ya can get your products cleared fast.
What is NOM Certification in Mexico?
NOM Certification is how the Mexican government makes sure the stuff you’re selling is safe, legal, and good enough for the local market. It’s not optional — if you want to do business in Mexico, you need this cert.
The standards come from something called Norma Oficial Mexicana (NOM), which literally means Official Mexican Standard. Think of it as the rulebook for products — whether it’s electronics, toys, appliances, food, or industrial goods.
What Is a NOM?
NOM stands for Norma Oficial Mexicana, which translates to Official Mexican Standard.
A NOM is a technical regulation issued by the Mexican government. It defines mandatory requirements for products, services, processes, and systems to ensure safety, health, environmental protection, and consumer rights in Mexico.
In simpler terms:A NOM tells you what a product or service must comply with to be legally sold or used in Mexico.
Why Does NOM Certification Matter?
Because Mexico’s government wants to protect consumers and keep dangerous or low-quality products out. That means:
Electrical stuff won’t catch fire
Food and drinks won’t make people sick
Labels actually show what’s inside
And for businesses like yours, it
Who Needs NOM Certification?
Electronics (TVs, chargers, LED lights)
Home appliances (blenders, refrigerators, irons)
Telecom gear (routers, cellphones)
Medical devices
…then you probably need NOM.
Even if you’re just shipping to Amazon Mexico or supplying a retailer, you’ll likely be asked to show proof of NOM compliance.
How to Get Started?
Don’t wait until customs blocks your shipment. Start by:
Finding out which NOM standard applies to your product
Choosing a certification body (there are several in Mexico)
Submitting samples and documents
Preparing for audits if required
Getting your NOM certificate and product mark
Need help? Many businesses use compliance consultants or local agents to guide them through the process faster.
What is NOM 001?
NOM-001-SCFI-2018, commonly referred to as NOM 001, is a mandatory Mexican standard that sets the safety requirements for electronic equipment powered by electricity, particularly those operating at up to 1000 volts AC or 1500 volts DC and intended for use in homes, offices, or similar environments.
This standard is essential for companies that manufacture, export, or sell electrical and electronic products in Mexico — including TVs, laptops, chargers, microwaves, and more.
Key Objectives of NOM-001:
Ensure electrical safety to prevent risks such as electric shock, fire, or overheating.
Protect consumers by verifying that products meet consistent quality and safety standards.
Standardize compliance for manufacturers, importers, and distributors in the Mexican market.
What is NMX Standard Mexico?
NMX stands for “Norma Mexicana”, which translates to Mexican Standard. These are voluntary technical standards developed by the Mexican government or accredited organizations to guide best practices in product design, manufacturing, services, labeling, and more.
While NOM (Norma Oficial Mexicana) standards are mandatory, NMX standards are optional—but still carry significant value, especially for companies looking to boost product quality, consistency, and acceptance in the Mexican market.
Key Features of NMX Standards
Voluntary, Not Regulatory
NMX standards are not legally required for market entry. However, they serve as quality benchmarks, and many businesses choose to adopt them to strengthen their market position or meet client expectations.Best Practice Guidelines
Think of NMX as a playbook for best practices. They cover areas like:Product performance
Packaging & labeling
Service quality
Manufacturing processes
Environmental and social responsibility
National Recognition
Though optional, NMX standards are developed under official Mexican institutions (e.g., Secretaría de Economía or national standards organizations like ANCE or NYCE), so they are widely recognized by regulators and business partners.Basis for NOM Standards
Many NOM standards are based on NMX. A product aligned with NMX is often partially or fully compliant with certain NOMs, making formal certification easier later on.Used for Certification & Bids
Some government or private tenders may require proof of NMX compliance, especially for industries like:Construction (NMX-C)
Environmental systems (NMX-S)
NOM vs NMX — What's the diff?
Standard | Is it required? | What it covers |
NOM | Yep | Safety, quality, labels |
NMX | Nope (unless NOM says so) | Best practices |
How NOM Certification Works in Mexico: Step-by-Step Guide
1. Check If NOM Applies to Your Product
Before you start, confirm whether your product falls under mandatory NOM standards. Products like electrical appliances, IT equipment, lighting, toys, and packaged food often require certification.
Tip: Search the NOM directory or consult with a compliance expert to avoid delays or incorrect filings.
2. Identify the Correct NOM Standard
Different products fall under different NOM standards, such as:
NOM-001 – for electrical safety
NOM-003 – for household appliances
NOM-050 – for labeling requirements
NOM-051 – for food and beverage labeling
Make sure you identify all applicable NOMs, especially if your product falls under multiple categories.
3. Contact Accredited Testing Labs in Mexico
Mexico requires that product testing be conducted by authorized testing laboratories (laboratorios de prueba acreditados) inside the country.
These labs:
Run safety and performance tests per the relevant NOM standard
Prepare a technical report accepted by certification bodies
May offer pre-evaluation advice on product readiness
4. Prepare Your Technical Documentation
You’ll need a technical file that includes:
Product specifications
Electrical schematics or layout
Safety information
User manuals (in Spanish)
Product labels and markings
Manufacturer declaration
Make sure all documentation aligns with NOM labeling and content rules.
5. Submit to a Certification Body (CB)
Once your product is tested and documentation is ready, you submit the full application to an accredited Certification Body (Organismo de Certificación de Producto, OCP).
They’ll review your test results, inspect your documents, and determine whether your product qualifies for NOM certification.
6. Undergo Product Testing
Testing is the heart of the NOM process. Your product is evaluated under Mexican standards to ensure it:
Meets electrical/mechanical safety requirements
Functions as described
Meets energy efficiency or labeling criteria (if applicable)
Any failure at this stage can delay or block certification — so preparation is key.
7. Factory Audit (if required)
Some NOM standards — especially those involving continuous production or safety-critical goods — require a factory inspection.
This audit checks:
Manufacturing processes
Quality assurance systems
Product consistency
Labeling and packaging integrity
The audit must often be completed on-site, and recurring audits may be required to keep the certificate valid.
8. Receive the NOM Certificate & Authorization to Use the NOM Mark
Once approved, you receive:
A NOM certificate valid for your product
Authorization to apply the NOM compliance mark on your goods
You can now legally import, distribute, and sell the product in Mexico.
The NOM mark must be visible on the product, packaging, or label — depending on the standard.
9. Keep Your Certificate Valid
NOM certificates have expiration dates (often 1–2 years), depending on the product and certification type.
To stay compliant, you may need:
Renewal testing
Ongoing audits
Label updates if your product changes
Re-application if regulations change or the standard is updated

How NOM Labs Help
NOM labs don’t just eyeball your product—they test it in controlled environments. Depending on your product type, they’ll check:
Electrical safety
Thermal resistance
EMC (Electromagnetic Compatibility)
Energy efficiency
Environmental performance
These aren’t one-size-fits-all tests. Each NOM has its own checklist.
Perform Product Inspections
Some labs do physical inspections too. They’ll:
Open up your product and check internal components
Inspect labels for correct Mexico-language warnings
Cross-check packaging and instructions
This ensures what you send to market is the exact version you had certified.
Certify and Verify Compliance
Once the tests are done, labs issue test reports that go to the Certification Body (CB). Without this step, no NOM certificate gets approved. Labs also help verify documents and sometimes coordinate directly with CBs to smooth the process.
Why Picking the Right Lab Matters
Not all labs are equal. A bad lab might:
Delay your product launch
Fail to test to the right NOM standard
Charge hidden re-testing fees
So, it pays to go with a reputable, accredited NOM lab that knows your product type.
