Annex 2.4.1 of the Agreement issuing the Ministry of Economy's general Foreign Trade Rules and criteria is amended

On September 28, 2026, Mexico's Ministry of Economy (Secretaría de Economía, SE) published in the Federal Official Gazette (DOF) the "Agreement Amending the Agreement Issuing the Ministry of Economy's General Foreign Trade Rules and Criteria" which updates Annex 2.4.1, known as the Annex of Official Mexican Standards (NOM). 

This update adds and amends the goods subject to compliance with certain NOMs at the point of entry into the country, with the aim of closing regulatory gaps and ensuring that products falling within the scope of these standards demonstrate compliance at the time of importation. 

As with any amendment to the NOM Annex, its applicability will depend on whether each company's goods are classified under one of the tariff items added or amended.

What is being added to annex 2.4.1?

Below is a summary of the Official Mexican Standards whose goods were added or amended in the Annex, along with their enforceability date:

Key points

• Plumbing fixtures: Goods regulated under NOM-012-CONAGUA-2021, applicable to faucets, valves and fittings for potable water plumbing installations, are added to Annex 2.4.1.
• Electric motors: Goods regulated under NOM-033-ENER-2019, relating to the energy efficiency of certain alternating-current electric motors, are added.
• Telecommunications: Tariff items related to mobile terminals and telecommunications devices subject to NOM-221-SCFI-2017 and NOM-221/2-SCFI-2018 are added, including smartphones, other mobile equipment, and certain equipment for receiving, converting, emitting or transmitting data.
• Compliance at the point of entry: Importers whose goods fall under the added tariff items must demonstrate compliance with the applicable NOM at the point of entry into national territory, in accordance with the specific notations set out in Annex 2.4.1 for each of them.
