Mexico NOM / IFT Certification Guide

Market access in Mexico depends on four parallel tracks: NOM safety certification, NOM labeling and Spanish-language marking, IFT wireless type approval, and energy-efficiency NOM. Miss any one of them and your goods can be held at the port.

Bottom line first: electrical and electronic products exported to Mexico generally need to clear NOM safety certification first. Certificates are issued by certification bodies approved under the Mexican Ministry of Economy (SE, Secretaría de Economía) system, such as NYCE and ANCE, and the holder must be a Mexican company — an entity with an RFC tax number (RFC, Registro Federal de Contribuyentes). A Chinese factory or brand owner cannot hold the certificate directly. Labels and manuals must be in Spanish and must carry the NOM mark and the certificate number. Products with radio functions such as Bluetooth and WiFi also need a separate IFT (Instituto Federal de Telecomunicaciones, Federal Institute of Telecommunications) type approval: the two tracks do not replace each other, and holding NOM does not mean the wireless side will clear. Products supplied with an external power adapter carry one more layer: energy-efficiency NOM. Timelines and costs vary widely by category and are subject to assessment by the certification body and laboratory.

Certification Overview

Certification	Authority	Scope	Mandatory	Reference timeline
NOM safety certification e.g. NOM-001-SCFI-2018, subject to the version currently in force	Regulated under the Ministry of Economy (SE) system; certificates issued by bodies such as NYCE / ANCE	Electrical and electronic equipment, battery chargers, standalone power supplies, UPS, etc.	Mandatory	About 4–8 weeks (subject to the body's assessment)
NOM labeling and commercial information marking e.g. NOM-050-SCFI, subject to the version currently in force	Ministry of Economy (SE)	Consumer product packaging, labels and manuals sold in Mexico	Mandatory	Handled in parallel with safety certification
IFT type approval	Federal Institute of Telecommunications (IFT)	Products with wireless / RF transmitting functions (Bluetooth, WiFi, cellular)	Mandatory	Depends on radio system, band and laboratory scheduling; subject to assessment
Energy-efficiency NOM e.g. NOM-029-ENER-2017, subject to the version currently in force	Energy efficiency authority (CONUEE) and the SE system	External power adapters, some household appliances and lighting products	Mandatory depending on category	Can run in parallel with safety certification
UN 38.3 battery transport	Transport stage (IATA/IMDG Class 9)	Products containing lithium batteries	Mandatory for transport	About 2–3 weeks

The real threshold is who holds the certificate: Mexican customs clearance checks that the certificate holder is a local legal entity. However well the product performs in testing, it cannot enter without a Mexican company (RFC) holding the certificate. The logic mirrors Brazil's requirement for a local CNPJ holder; see the Brazil ANATEL guide.

Who Needs It: A Four-Step Product Profile

Run a new product's datasheet through the four steps below and the requirements usually become clear

Mains-powered or contains a power supply

Chargers, standalone power supplies, UPS → NOM safety applies

Contains radio frequency

Bluetooth / WiFi / cellular → add IFT type approval

Comes with an external adapter

External power supply → add energy-efficiency NOM

Contains a lithium battery

UN 38.3 + Spanish labels + transport documents

The reverse holds too: a product with no radio module needs no IFT model approval. That is already settled for purely DC products such as power banks: no Bluetooth and no wireless charging removes the entire block of RF testing, and both timeline and cost drop noticeably. NOM safety and Spanish labeling still apply, though — see the certification breakdown for power bank exports to Brazil and Mexico. As for products "entirely outside any NOM scope", that has to be confirmed category by category; it cannot be settled with a line about "no wireless".

NOM Labeling and Spanish-Language Requirements

Labeling is one of the checks Mexican customs performs regularly — and one of the costliest items to fix after the fact

Spanish is a hard requirement

Labels, packaging and manuals must be in Spanish. Chinese-English bilingual packaging counts as a missing language element in Mexico and means reprinting or over-labeling.

NOM mark and certificate number

The product must show the NOM mark and the corresponding certificate number, consistent with the product information declared on the certificate. A mistyped certificate number invalidates the label.

Importer information

Under commercial information marking requirements, the label usually has to show the Mexican importer's name and RFC tax number, country of origin and similar details (subject to the version of NOM-050-SCFI currently in force). If the importer changes, the label must be updated at the same time.

Commercial information marking NOM

Beyond the safety NOM, commercial-information and manual marking requirements also apply (the NOM-050-SCFI, NOM-024-SCFI type, subject to the version currently in force), and they are often overlooked.

Practical advice: have the certification body review the label artwork before tooling and printing, not after the certificate is issued. Changing a label means changing packaging, the production line and inventory — far more expensive than two extra days of confirmation up front.

Electrical Safety: How NOM Safety Certification Works

NOM-001-SCFI-2018 is the main safety standard for electronic equipment, and it explicitly covers battery chargers, standalone power supplies and UPS

Scope and coverage

The main standard is NOM-001-SCFI-2018 (safety requirements and test methods for electronic equipment, subject to the version currently in force). Battery chargers, standalone power supplies and UPS are explicitly in scope, and products such as power banks fall under it.

Main test lines

Technically it follows North American safety practice: dielectric strength, insulation, temperature rise, abnormal operation, mechanical protection, battery abuse and more. The specific clauses, pass limits and sample quantities are subject to the version of that standard currently in force and to laboratory assessment.

Certificate validity

A NOM certificate is usually valid for about 5 years, with periodic surveillance audits in between. Start renewal before expiry to avoid a gap.

Key Information

Certificate holder	Mexican company (holding an RFC)
Issuing bodies	SE-approved bodies such as NYCE / ANCE
Reference timeline	About 4–8 weeks (based on power bank type products; subject to assessment)
Reference cost	Low thousands of US dollars (USD 3,000–8,000 range, subject to the body's quotation)
Certificate validity	Usually about 5 years, with periodic surveillance audits
Factory inspection	Per the surveillance audit arrangements during the validity period

One standard number does not cover everything: NOM is a family of standards organized by category, and different products map to different NOM numbers and versions. The numbers cited here are for reference only; which version actually applies, and whether a newer one has superseded it, is subject to the official version currently in force.

Wireless Devices: IFT Type Approval

Required whenever radio is present — and a separate track from NOM

The IFT (Federal Institute of Telecommunications) governs the radio and telecom layer, focusing on radio parameters such as frequency bands, transmit power, bandwidth and spurious emissions; NOM governs electrical safety and labeling. NOM does not replace IFT, and the reverse is equally true. Teams often treat the two as "one certificate", and the result is a request for additional documents at the port.

Trigger conditions

Any product with a wireless transmitting function — Bluetooth, WiFi, cellular, wireless charging and the like — falls within the scope of IFT type approval. A product without a radio module needs no IFT, which is already settled for power bank type products.

Relationship with FCC

Test methods and part of the limit rationale are close, so an FCC report can serve as a technical basis and as a starting point for a gap analysis, but it cannot replace IFT certification outright. Mexico's band allocations and power limits are subject to the technical provisions IFT currently issues.

Key Information

Authority	Federal Institute of Telecommunications (IFT)
Certificate holder	Requires cooperation from a Mexican local entity
Reference timeline	Depends on radio system, band and laboratory scheduling; subject to assessment
Technical basis	Current IFT technical provisions; FCC conclusions cannot simply be carried over
Common categories	Bluetooth earphones, WiFi devices, cellular terminals

For the general compliance path for Bluetooth products, read this alongside the USA FCC/UL guide and Bluetooth product certification options; planning both North American markets together makes test schedules easier to combine.

Energy Efficiency: External Power Supplies and Adapters

Energy efficiency is a separate track: it does not conflict with safety certification, but it has to be declared on its own

Product form	Energy-efficiency requirement	Notes
AC adapter / external power supply shipped with the product	NOM-029-ENER-2017 applies (subject to the version currently in force)	Must be assessed and declared separately under the energy-efficiency NOM; safety-only testing is not enough
Power bank itself	Generally not applicable	The unit itself usually falls outside the scope of that energy-efficiency standard
Other appliances and lighting products	Other energy-efficiency NOMs apply	Different categories use different standards, subject to the version currently in force

Note: a power adapter sits under both energy-efficiency and safety requirements, so both sets of tests can run on the same sample batch, cutting shipping and waiting time. For the adapter certification path, see power adapter options and North American safety services.

Importer and RFC: Who Holds the Certificate, Who Clears Customs

This decides whether your goods actually land, and it matters more than the testing itself

The certificate holder

The NOM certificate holder must be a Mexican company — that is, an entity holding an RFC tax number. Chinese factories and brand owners cannot hold the certificate directly; the usual arrangement is for the Mexican importer or a local authorized representative to hold it.

Consistency at customs

The HS code on the NOM certificate must match the customs declaration. Power banks, for example, usually fall under 8507.60; if the certificate lists one code and the declaration states another, customs is unlikely to release the shipment. This has also been a focus of Mexican enforcement checks in recent years.

Key Information

Required entity	Mexican company (RFC)
Can the holder be a foreign company	No
HS code	Certificate declaration must match the customs declaration
Change of importer	Certificate and label must be handled together
Comparison with Brazil	Brazil requires a local CNPJ; same logic

A pragmatic approach: settle the holding relationship, the division of responsibility and certificate ownership with the Mexican importer before starting tests. Many projects stall not in the laboratory but on "the certificate was issued, but it isn't yours, and the importer has changed".

Common Pitfalls: Where Mexico Exports Go Wrong

Assuming no Bluetooth means no work

Having no radio only exempts you from IFT; NOM safety and Spanish labeling still apply. Judge the two tracks separately.

A Chinese company holding the certificate

The certificate holder must be a Mexican company (RFC). A certificate in your own name cannot actually be used for import clearance.

HS code mismatch

A code on the certificate that differs from the customs declaration is a frequent cause of seizure. Cross-check the certificate, the invoice and the customs declaration before shipment.

Labels in Chinese and English only

Missing Spanish, or a missing NOM mark, certificate number or importer RFC, all count as non-compliant labeling.

Forgetting UN 38.3

For products containing lithium batteries, the UN 38.3 test report and MSDS are a transport necessity; without them the freight forwarder will not take the goods. This sits outside certification.

Using FCC / CE reports instead of NOM

A report can serve as a technical basis; it cannot stand in for a certificate. The NOM certificate must be issued by an approved body in Mexico.

Treating an old version as current

NOM numbers carry a year, and versions get superseded. Confirm the version in force before kick-off rather than preparing samples to a standard from several years ago.

Ignoring differences in port practice

Inspection practice can differ from port to port. Confirming the current position with your importer before shipment is cheaper than fixing it afterwards.

Reusing Reports from Other Countries

Data and engineering conclusions can be reused; the certificate itself cannot

Existing certification	Degree of reuse	What still has to be added
USA FCC / UL	Safety test lines and RF test methods are close; can serve as a technical basis	The NOM certificate must be issued by an approved body in Mexico; IFT differences must be confirmed against Mexican technical provisions
Canada ISED / CSA	Safety standard content aligns with the North American system; the data is valuable for reference	The local certificate holder and labels still have to be redone to Mexican requirements
EU CE (LVD/EMC/RED)	Engineering data can be used for gap analysis	Standard versions and pass criteria differ; compare item by item and add testing
Brazil ANATEL	Also a Latin American market; document structure and the local-entity holding logic are comparable, so preparation can run in parallel	The language is Spanish rather than Portuguese, the regulatory system differs, and mutual recognition does not apply

One-line principle: a report is citable evidence; a certificate is a permission granted by the local regulator. The first saves test time and samples; the second can only be applied for locally. Which items can be cited is subject to written confirmation from the accepting body and the laboratory.

FAQs

My product has no Bluetooth or WiFi — do I still need IFT?

No IFT model approval is needed. IFT governs radio transmission, and a product without a radio module is outside its scope. NOM safety certification, Spanish labeling and the importer RFC still apply, though; you cannot skip the whole package just because there is "no wireless". Power bank type products are the usual example: RF is exempt, but safety and labeling apply in full.

Can a Chinese company hold a NOM certificate directly?

No. The NOM certificate holder must be a Mexican company (holding an RFC tax number). Overseas manufacturers usually hold it through the Mexican importer or a local authorized representative, and that local entity is exactly what customs looks at during clearance. The logic mirrors Brazil's local-CNPJ requirement; it is a fixed cost and cannot be avoided.

How long is a NOM certificate valid, and what happens at expiry?

Usually about 5 years, with periodic surveillance audits in between. Start renewal before expiry, and check whether the standard version in force has changed — if the standard has been revised, renewal may require additional testing. Specific renewal requirements are subject to notification from the issuing body.

I already have FCC or CE reports — can I skip testing?

You can save part of the work, but not the certificate. FCC and CE reports can serve as a technical basis for gap analysis and data citation, reducing duplicate testing and sample quantities; the NOM certificate must still be issued by an approved body in Mexico, and IFT differences must also be confirmed against Mexico's current technical provisions. Which items can be cited is subject to written confirmation from the accepting body and the laboratory.
