01Entering This Market
In Mexico, NOMs are mandatory technical regulations applied according to product group. A frequently overlooked aspect of the regime is that labelling is itself a separate NOM matter: even if a product meets the safety NOM, a shipment that does not meet the Spanish-language labelling requirements can be held at customs.
02Background to the Regime
At the centre of Mexico's conformity system are the MANDATORY OFFICIAL STANDARDS. These are not ordinary standards but legally binding technical regulations: a product within their scope cannot be imported or sold without its conformity to the relevant standard being certified. Each standard carries its own scope, test method and labelling requirement.
The evidence is a certificate of conformity issued by an authorised certification body. Testing is carried out in accredited laboratories within the country; acceptance of foreign reports is limited and varies by standard.
The most frequently overlooked aspect of the regime is that LABELLING is a conformity subject in its own right. The commercial information label, the Spanish language requirement, units of measurement and mandatory information items are governed by a separate mandatory standard and are checked at customs. A shipment can be stopped because of the label even where the product is technically compliant.
The radio and telecommunications side is administered by a separate authority and requires a separate approval; frequency allocations are national. Having obtained a product safety certificate does not take the place of radio approval.
The application runs through an importer established in the country. The scope of the certificate is limited to the model and manufacturer; a change of importer in some cases requires the certificate to be reissued.
03Acceptance of Foreign Test Reports and Documents
- Testing is as a rule carried out in accredited laboratories within the country; acceptance of foreign reports varies by standard and is limited.
- Labelling is subject to its own mandatory standard; the Spanish commercial information label is a separate conformity subject.
- Radio approval is granted by a separate authority; a product safety certificate does not satisfy it.
- The certificate is obtained through an importer established in the country and its scope is limited to the model and manufacturer.
- Certificates obtained for other markets in North America are not directly valid; the mandatory official standards require their own evidence.
04Defining Features of the Regime
- NOMs are mandatory technical regulations; multiple NOMs may apply to a product
- Labelling is a separate NOM matter and is inspected at customs
- Certification is carried out by an accredited body
- Tests are conducted at accredited laboratories in Mexico or under mutual recognition
- Radio and telecom equipment is subject to IFT homologation
- Certificate scope is defined on a model basis
05Local Representative and Responsible Party
An importer resident in Mexico is required, and the NOM certificate is mostly issued in the importer's name. Importer information is mandatory on the Spanish-language label; therefore, label design cannot be finalized without first determining the distribution partner.
07Entry Process
- 01Scope DeterminationIt is determined which legislation and marking scope the product falls under in the target market. This step defines the entire process; getting it wrong wastes all subsequent work.
- 02Determining Applicable StandardsThe standards accepted by the market and any national deviations are identified. The same IEC standard may apply with different deviations in different markets.
- 03Establishing the Test PlanIt is assessed which part of existing test reports will be accepted; missing tests are planned. A CB Scheme report, if available, reduces retesting.
- 04Local Party and RegistrationIf the market requires an established representative, importer or applicant, this party is designated and the necessary registrations are made.
- 05Tests and Technical FileTests are conducted and the technical file is prepared. Some markets require testing to be performed within their own country.
- 06Certification or DeclarationDepending on the market's regime, a manufacturer's declaration is drawn up or a certificate is obtained from the authorised body; a factory audit is carried out if required.
- 07Marking and LabellingThe mark and label are applied according to the market's format and language rules. The language requirement is checked at customs in most markets.
- 08Shipment and CustomsIf a pre-shipment document is required, it is obtained; the document set to be presented at customs is completed.
08Customs and Labelling
- A Spanish-language label is mandatory: product name, country of origin, importer information, and warnings
- The NOM certificate is presented at customs
- The homologation number is shown on products within IFT scope
- Energy efficiency NOMs additionally apply to products within their scope
- The label is expected to be applied before customs clearance
09Common Mistakes
- Not knowing that the labelling NOM is a separate obligation
- Printing the label without importer information
- Incompletely determining the NOMs applicable to the product
- Skipping IFT homologation
- Shipping model variants not included in the certificate scope
10Calendar
The certification timeline varies with the product, the required test workload, sample shipping time and the authority's workload; for this reason, no duration in days or weeks is given on these pages. The main factors determining the timeline are: whether testing must be performed in the target country, whether a factory audit is required, the time to appoint a local representative, and the current maturity of the technical file. A realistic timeline for your product is provided in writing at the quote stage.
Market access regimes change frequently: scope lists are updated, transition periods are extended, new requirements are added. These pages describe the structure of the regime and who bears the obligation; the applicable scope and dates for your product are confirmed from the current legislative text at the quote stage.
11Frequently Asked Questions
Why is the labelling NOM a separate matter?
Labelling is a mandatory regulatory matter in its own right in Mexico. Even if a product meets the safety NOM, one that does not meet the Spanish-label requirements can be held at customs. The two must be handled separately.
