Mexico’s NOM certification (Normas Oficiales Mexicanas) is a mandatory product safety and performance compliance system regulated by SE (Ministry of Economy).
In 2025, several key updates expand NOM’s coverage across electronics, IT, lighting, and EV-related products, ensuring higher product safety and energy efficiency standards.
| Product Category | Applicable NOM Standards | Key Testing Scope |
|---|---|---|
| Electronics & Household Appliances | NOM-001-SCFI (Safety/EMC) NOM-003-SCFI (Safety) NOM-016-ENER (Energy Efficiency) | Dielectric strength, insulation resistance, leakage current, EMC (radiated/conducted), energy efficiency (standby power). |
| IT & Telecom Equipment | NOM-001-SCFI (EMC) NOM-019-SCFI (Safety/EMC) NOM-208-SCFI (RF) | EMC, RF testing (for wireless devices), electrical safety. |
| Lighting & LED Products | NOM-003-SCFI (Safety) NOM-030-ENER (Energy Efficiency) | Electrical and photobiological safety, energy efficiency. |
| Medical Devices | NOM-241-SSA1 (Safety & Health Registration) | Biocompatibility, electrical safety, performance validation. |
| Children’s Toys | NOM-252-SSA1 (Safety) | Heavy metals content, mechanical and physical safety (choking hazard). |
| Auto Parts | NOM-003-SCT (Safety & Emissions) | Strength, durability, safety and environmental testing. |
| Industrial Equipment | NOM-004-SCFI (Mechanical Safety) NOM-029-STPS (Safety) | Mechanical safety, operator protection. |
| Food Contact Materials | NOM-051-SCFI/SSA1 (Health) | Chemical migration, hygiene and safety performance. |
2025 Expansion: The NOM certification scope now covers EV charging stations, photovoltaic modules, and lithium batteries, reflecting Mexico’s growing focus on energy transition and e-mobility.
Mexico’s NOM system applies different certification models depending on product type, import frequency, and manufacturer presence.
Suitable for single shipment or small batch imports.
Testing and approval apply only to that shipment.
Ideal for long-term exports or continuous imports.
Requires factory audits, annual supervision, and ongoing quality control.
Includes smart energy devices, EV infrastructure, and battery-powered systems under safety and efficiency regulations.
Tip: For global brands, starting with Registry Certification provides smoother customs clearance and less annual paperwork.
1️⃣ Local Legal Representative Required:
All NOM certificates must be held by a Mexican-registered entity (importer or subsidiary).
2️⃣ Language & Labeling:
All labels, user manuals, and test reports must be in Spanish and include:
Rated Voltage: 127V
Frequency: 60Hz
Manufacturer/importer details
3️⃣ Testing Location Requirements:
Energy Efficiency Tests (e.g., under NOM-016-ENER) must be performed inside Mexico.
CB or foreign reports are not accepted for these tests.
4️⃣ Certificate Maintenance:
Factory inspections may occur annually or upon renewal.
Non-compliance can result in certificate suspension or customs hold.
✅ Plan Ahead for Energy Testing:
Schedule in-country tests early to avoid shipping delays — Mexican labs can have long queues.
✅ Integrate CB + NOM Strategy:
While CB reports aren’t fully recognized, aligning your IEC safety testing with NOM requirements reduces retest failures.
✅ Use an Experienced Partner:
Work with certified consultants (like BLUEASIA) familiar with NOM, IECEE, and LATAM market entry to ensure document alignment and local representation.
Mandatory for products entering the Mexican market.
Ensures compliance with electrical, safety, and efficiency standards.
Required for customs clearance — shipments lacking NOM certificates may be detained.
Enhances brand credibility and facilitates entry into broader LATAM markets.
