A client once asked me: "What exactly does Mexico NOM cover? Do all electronic products exported to Mexico need it?"
Not all.
NOM is split by category, by agency, and by standard number. Some fall under DGN (the standards directorate under the Ministry of Economy), others under IFETEL (the Federal Telecommunications Institute, commonly shortened to IFT). The catalogues, standards, and certification bodies are all different. Get it wrong and your goods are detained at port – demurrage is charged by the day.
DGN (Dirección General de Normas) – the standards directorate under the Ministry of Economy – manages the NOM catalogue but does not issue certificates directly. Electrical safety CoCs (Certificates of Conformity) are issued by third parties recognised by the Ministry of Economy – ANCE and NYCE are the actual issuers.
1.1 Household appliances
Household appliances are the mainstay of NOM. Refrigerators, washing machines, microwaves, air conditioners, vacuum cleaners, coffee makers, induction cooktops, electric ovens – all covered. Small appliances and cleaning appliances are all included.
1.2 Audio‑video and IT equipment
Audio‑video and IT equipment are also major categories. TVs, speakers, projectors, monitors, printers, laptops – governed by NOM-001-SCFI-2018 – HBSE methodology aligned with IEC 62368-1.
1.3 Lighting products
Lighting products fall under NOM-058-SCFI. LED bulbs, fluorescent tubes, ballasts, streetlights – all listed. Don't assume low power means exemption – the catalogue does not differentiate by power – fixed‑installation general lighting is mandatory.
1.4 Power tools
Power tools – drills, angle grinders, saws, welding machines – fall under NOM-003-SCFI.
1.5 Industrial equipment
Industrial equipment is often overlooked. Motors, transformers, distribution cabinets, switch‑mode power supplies – many manufacturers assume industrial products are exempt. Wrong. If it's on the SE mandatory import list – whether sold to factories or consumers – it needs NOM to enter Mexico. High‑power, high‑voltage specialised equipment is mostly not on the list – don't assume all industrial equipment is covered.
2. Automotive Electronics – Classification Rules (Front‑Load vs. Aftermarket)
Automotive electronics need separate discussion – front‑load and aftermarket are treated differently.
2.1 Aftermarket automotive products
Aftermarket products – aftermarket head units, in‑vehicle chargers, retrofit dashcams, external T‑Boxes – are consumer electronics sold independently – governed by NOM-001. Without wireless: electrical safety NOM only. With Wi‑Fi, Bluetooth, or cellular – add IFETEL.
2.2 Front‑load OEM automotive components
Factory‑fitted front‑load head units and OEM T‑Boxes are vehicle components – not governed by NOM-001 – they follow vehicle regulations (REPUVE, etc.) – no NOM certificate required. OEMs often make this mistake – spending money on NOM for factory‑fitted components that don't need it.
3. IFETEL (IFT) – Radio Homologation Scope
IFETEL (Instituto Federal de Telecomunicaciones – Federal Telecommunications Institute, commonly shortened to IFT). Any radio transmitting device used in Mexico must pass Homologación – the certificate is called Certificado de Homologación. After 2023, a single certificate – Certificado Único – was introduced – wireless terminals no longer receive separate NOM-208 certificates.
3.1 Short‑range wireless devices (Bluetooth/Wi‑Fi)
Bluetooth: headsets, speakers, keyboards, mice, modules – all operating in the 2.4 GHz ISM band – fall under IFETEL. Wi‑Fi devices: routers, modules, smart home – also in scope.
3.2 Cellular communication devices
Cellular: 4G/5G phones, cellular routers, in‑vehicle T‑Boxes, cellular‑enabled tablets – testing must cover all commercial bands used by Mexican operators.
NOM-208-SCFI-2023 – with technical specification IFT-017-2023 – was issued in late 2023 – consolidating radio spectrum technical requirements for telecom terminals into a single document.
3.3 Low‑power short‑range devices
Low‑power short‑range: ZigBee, RFID, NFC readers, remote key fobs, wireless doorbells – low transmit power does not mean IFETEL exemption. Devices below thresholds may be simplified – but not automatically exempt.
3.4 Wireless chargers – special rules
Wireless chargers: pure energy‑transfer Qi charging pads without communication – theoretically no IFETEL homologación required – but port‑of‑entry enforcement varies. Before shipping, confirm local practice with your importer. Integrated NFC – separate approval required.
4. Two‑System Overlap – Common Traps
Most failed projects come from not understanding the DGN‑IFETEL overlap. Every customs season, there are several cases.
4.1 Smart appliances (with wireless)
Smart appliances with Wi‑Fi/Bluetooth are typical. Smart air conditioner: NOM-001 electrical safety – plus IFETEL homologación for the Wi‑Fi module – both required. Customs checks list both DGN and IFETEL classes – missing one holds the entire container.
4.2 In‑vehicle navigation head units
Same pattern. Head unit: NOM-001 safety. Built‑in Wi‑Fi, Bluetooth, cellular modules: IFETEL.
4.3 Pure wireless Bluetooth headsets
Pure wireless Bluetooth headsets are simpler – only IFETEL – one line.
5. Products That Do
Products that don't connect to mains, don't involve safety, and aren't on the catalogue – no NOM required. Purely mechanical with no electrical risk – DGN doesn't cover them. Products that don't transmit – IFETEL doesn't cover them. Data cables, adapters, passive antennas – generally not on the catalogue.
Battery‑powered offline devices without wireless – not on the mandatory catalogue. NOM-212 applies to independently imported/sold lithium battery cells or packs. For finished products with built‑in batteries that already have NOM certification – the built‑in battery does not need separate NOM-212 – this is a common area of wasted spend.
If the hardware has RF circuitry – regardless of whether the antenna or software is disabled – IFETEL considers it a wireless device requiring homologación. The criterion is whether the circuit has RF transmission capability – the antenna does not affect the conclusion. The safe path: remove the RF chip or physically cut the RF circuit.
6. Real Risks of Skipping NOM Certification
Let's talk consequences.
E‑commerce platforms also check. Mercado Libre and Amazon Mexico have been routinely verifying certificates since 2023 – and in 2025, enforcement tightened – no certificate = listing frozen. Getting into offline channels is even harder – Walmart and Liverpool's procurement catalogues block uncertified products.
PROFECO audits are not a formality. Products on the mandatory catalogue without NOM – fines start – delisting follows – serious violations can even suspend your business license.
7. 2026 NOM Certification – Enforcement Tightening
Both DGN and IFETEL are upgrading enforcement. Customs has shifted from random sampling to shipment‑by‑shipment verification – the days of relying on luck are over. IFETEL is progressing revisions to NOM‑208 implementing rules – IFT-017-2023 update is still in draft – Wi‑Fi 6E and 6 GHz are expected to be expanded.
In 2026, DGN is intensively revising standards – the NOM-001 update draft is already out for consultation – IEC 62368-1 upgrading to the 2023 edition is only a matter of time. During the old‑new standard transition, confirm the applicable version before starting – using the wrong version means wasted retesting.
