New customs guidance explains how missing or inaccurate commercial information under applicable NOMs will be handled during import procedures.
At a glance
· Mexico’s customs authority has clarified enforcement when goods do not meet NOM commercial-information requirements.
· If NOM compliance cannot be demonstrated, goods may be subject to precautionary seizure and more serious consequences.
· If compliance is demonstrated and the issue is limited to missing or inaccurate information, a fine of 2%–10% of the goods’ commercial value may apply.
What has Mexico ANAM clarified?
Mexico’s National Customs Agency (ANAM) issued Press Release 74/2026 on 8 September 2026, together with an official guidance criterion, explaining how customs authorities should handle non-compliance with Mexican Official Standards (NOMs) covering commercial information.
The clarification follows amendments to Mexico’s Customs Law and distinguishes between two situations: failure to demonstrate NOM compliance and cases where the product complies but required commercial information is missing or inaccurate.
What happens if NOM compliance cannot be demonstrated?
Where customs authorities identify non-compliance with an applicable commercial-information NOM, the goods may be subject to precautionary seizure.
If the importer cannot demonstrate compliance during the administrative customs procedure, the goods may ultimately become property of the Federal Treasury.
However, the importer may still remedy the applicable non-tariff requirements within 30 days following notification of the initiation of the customs administrative procedure.
What if the product complies but the information is incorrect?
ANAM distinguishes technical or substantive non-compliance from cases where compliance can be demonstrated but required information has been omitted or presented inaccurately.
Where the issue is limited to missing or inaccurate commercial information, a fine equivalent to 2%–10% of the commercial value of the goods may apply.
This distinction is important for importers because a labelling or documentation error can therefore lead to a different enforcement outcome from a case where NOM compliance cannot be demonstrated at all.
Which products can be affected?
Mexico’s 2026 foreign-trade rules identify the commercial-information NOMs and data covered by these provisions in Annex 26 of the General Foreign Trade Rules.
For ICT and electronics manufacturers, the list includes NOM-024-SCFI-2013, covering commercial information for packaging, instructions and warranties of electronic, electrical and household appliances.
Other general commercial-information standards, including NOM-050-SCFI-2004, are also included.
The exact requirements depend on the product and applicable NOM.
What should manufacturers and importers check?
Companies placing products on the Mexican market should review commercial-information compliance before shipment, rather than treating labelling as a final administrative step.
Key checks include:
· applicable NOM commercial-information requirements;
· Spanish-language labelling and documentation;
· consistency of model and product information across labels, packaging and customs documents;
· instructions, warranties and importer information where required; and
· confirmation that documentation can demonstrate NOM compliance during customs clearance.
For manufacturers using a local importer, these checks should be coordinated before the goods arrive in Mexico to reduce the risk of customs delays, penalties or administrative proceedings.
