ANAM issued an interpretative criterion following the amendment to Article 158 of the Customs Law published on November 19, 2025. Failure to demonstrate compliance with applicable commercial-information NOMs may lead to precautionary seizure, penalties of 250% to 300% and loss of the goods.

Where compliance is demonstrated and the issue is limited to omitted or inaccurate data, the clarified treatment provides for a lower penalty range of 2% to 10%, subject to the applicable facts and law.

Impact

Impact assessment: High. Key reasons: The guidance concerns severe customs consequences, including precautionary seizure and penalties up to 300%, and directly affects evidence used to clear NOM-labelled imports.

Who is affected?

Mexican importers, foreign manufacturers, distributors, customs brokers, labelling and packaging teams, trade-compliance personnel, legal teams and businesses placing NOM-regulated goods on the Mexican market.

Conclusion:

Verify applicable NOM labelling before shipment, preserve conformity evidence for customs clearance, distinguish substantive non-compliance from data errors, and implement escalation procedures for any detention. Correct omissions before import whenever legally possible.
