Mexico City, Mexico — As of September 12, 2025, the service for sending letters and documents to the United States will resume. Postal service to the U.S. has started up again for envelopes not subject to tariffs.
According to Correos de México, the measure does not apply to packages, magazines, books or documents with commercial value. The Mexican government said it will continue talks with U.S. authorities to resume courier and parcel service as soon as possible.
“As part of the process of resuming postal services following the implementation of Executive Order 14324 of the United States Government, applicable to all countries worldwide, Correos de México is reactivating the delivery of letters and documents of non-commercial value to that country.
“This measure constitutes the first step in the reestablishment of services to the United States. In this regard, starting September 12, it will be possible to visit the more than 1,500 Mexican Post offices across the country, where they will be able to send only letters and documents to the United States,” the government reported.
Envelopes that can be sent include handwritten letters, postcards and administrative, legal, or academic papers, as long as they have no commercial value.
Although shipments of packages, courier services, printed publications, magazines, and books remain restricted until further notice, the Mexican government is conducting intensive coordination among relevant agencies, as well as maintaining ongoing dialogue with U.S. authorities, to reach agreements that fully restore postal services.
The announcement came after, on July 30 2025, the U.S. implemented Executive Order 14324, Suspending Duty-Free De Minimis Treatment For All Countries. The Secretary of Homeland Security has determined that appropriate action is needed to ensure collection of applicable duties as well as to modify the Harmonized Tariff Schedule of the United States
Executive Order 14324 suspends the duty-free de minimis exemption otherwise authorized under section 321(a)(2)(C) of the Tariff Act of 1930, as amended, for all covered products, regardless of country of origin, valued at $800 or less, and requires such articles, except articles that are sent to the United States through the international postal network, to be entered using an appropriate entry type in the Automated Commercial Environment (ACE) by a party qualified to make entry.
Executive Order 14324 also establishes a new duty rate for covered products that are sent to the United States through the international postal network.
