Mexico’s NOM (Normas Oficiales Mexicanas) certification remains a mandatory requirement for all electronic and electrical products entering the Mexican market.
In 2025, several major updates have been introduced — covering labeling, energy efficiency, cybersecurity, and specific product standards.
This article highlights the key regulatory changes, compliance process updates, and practical recommendations to help manufacturers and importers stay compliant.
| Effective Date / Status | Product / Area | Key Update Summary |
|---|---|---|
| October 1, 2025 | Customs Labeling | New QR-code-compliant customs label is mandatory. Product packaging and markings must be updated accordingly. |
| July 10, 2025 | Communications Equipment (IPv6) | Temporary approval plans terminated. All new applications and renewals now require full-protocol IPv6 testing. |
| November 29, 2025 (Phase 1) | Electric Motors | NOM-014-ENER-2025 takes effect for single-phase AC induction motors (0.180–2.238 kW). |
| October 25, 2025 | Motor Pumps | NOM-004-ENER-2025 becomes mandatory for motor-pump systems (0.149–1.492 kW) used in domestic clean water supply. |
| November 30, 2025 | Medical Devices | Updated GMP standard NOM-241-SSA1-2025 is now mandatory. |
| 60-day comment period (from notification) | Natural Gas Facilities | Draft standard PROY-NOM-022-ASEA-2025 covers portable storage modules and CNG station safety, replacing NOM-010-ASEA-2016. |
Since March 2025, Mexican customs has implemented a QR-code-based labeling system, with the transition period ending October 1, 2025.
➡️ All imported products must display this new label for customs clearance.
Certain smart or connected devices may now undergo anti-fraud and data privacy testing in accordance with EN 18031.
➡️ Always confirm with your certification body if your product category requires these cybersecurity evaluations.
Updated energy standards like NOM-029 now require wireless charging systems to achieve at least 75% power transfer efficiency, effective 2025.
➡️ Energy-related testing must be done in Mexican-accredited laboratories only.
1️⃣ Localization Errors:
Mexico operates on 127V/60Hz with U.S.-type plugs.
All labels, manuals, and documents must be in Spanish.
2️⃣ Improper Certificate Holder:
The NOM certificate must be held by a Mexican local entity (importer or subsidiary).
Overseas manufacturers cannot directly hold NOM certificates.
3️⃣ Testing Location Issues:
CB reports may be partially accepted, but local difference testing is still required.
Energy efficiency tests (e.g., NOM-016-ENER) must be fully performed in Mexico.
✅ Plan Ahead (3–4 Months):
Start preparations early, as average certification timelines range from:
4–8 weeks for simple products
2–4 months for complex or multi-model product lines
✅ Use Family Certification:
Consider applying for “family certification” to group similar products under one NOM certificate — this reduces per-unit testing costs and speeds up approval.
✅ Stay Proactive:
Monitor upcoming NOM and PROY-NOM drafts to anticipate new product-specific regulations, especially for smart, energy-efficient, and connected devices.
