Here’s a concise overview of Mexico’s NOM mandatory safety certification programs, standards, and testing scope based on 2025 updates.
| Product Category | Applicable Standards | Key Testing Scope |
| Electronics & Household Appliances | NOM-001-SCFI (Safety/EMC) NOM-003-SCFI (Safety) NOM-016-ENER (Energy Efficiency) | Electrical safety (dielectric strength, insulation resistance, leakage current), EMC (radiated/conducted emissions), energy efficiency (standby power) |
| IT & Telecom Equipment | NOM-001-SCFI (EMC) NOM-019-SCFI (Safety/EMC) NOM-208-SCFI (RF) | EMC, RF testing (if applicable), electrical safety |
| Lighting & LED Products | NOM-003-SCFI (Safety) NOM-030-ENER (Energy Efficiency) | Electrical safety, photobiological safety, energy efficiency |
| Medical Devices | NOM-241-SSA1 (Safety & Health Registration) | Biocompatibility, electrical safety, performance testing |
| Children’s Toys | NOM-252-SSA1 (Safety) | Chemical safety (heavy metals), mechanical/physical testing (small parts) |
| Auto Parts | NOM-003-SCT (Safety & Emissions) | Strength, durability, safety testing |
| Industrial Equipment | NOM-004-SCFI (Mechanical Safety) NOM-029-STPS (Mechanical Safety) | Mechanical safety testing |
| Food Contact Materials | NOM-051-SCFI/SSA1 (Health) | Chemical migration, hygiene performance |
Certification Modes & Concepts:
1.Type Approval: For single import batches.
2.Registry Certification: For long-term exports (requires factory audits and annual supervision).
3.Expanded Scope: Now includes EV charging stations, photovoltaic modules, and lithium batteries.
Key Reminders:
1.Local Representative: Certificate holder must be a Mexican entity.
2.Language & Labeling: All documents and labels must be in Spanish. Products must specify 127V/60Hz.
3.Testing Location: Energy efficiency tests (e.g., NOM-016-ENER) must be done in Mexico; CB reports are not accepted.
