For exporters in northern Mexico, the IMMEX program is much more than paperwork: it is what allows them to temporarily import inputs, parts and machinery without paying import taxes up front. Losing it can disrupt costs, inventories and customer contracts within weeks. That is exactly what happened this year to hundreds of companies that failed to file a report.
What happened
On June 30, 2026, the Ministry of Economy (Secretaría de Economía) published a notice in the Federal Official Gazette (DOF) listing 441 IMMEX programs suspended for failing to file the Annual Foreign Trade Operations Report for fiscal year 2025. Companies had until August 31 to get back into compliance; those that did could recover the benefit within two business days after filing.
For those that did not, the cancellation took effect on September 1, 2026. On September 14, the General Directorate of Trade Facilitation and Foreign Trade signed the notice listing the names of the holders and the numbers of the canceled programs, which, according to IDC Online, was published in the DOF on September 29. The notice is based, among other provisions, on articles 25, 29 and 30 of the IMMEX Decree.
Why it matters
The annual report is not the only ongoing obligation. According to Stratego's analysis, the IMMEX Decree requires the report to be filed electronically no later than the last business day of May, with total sales and exports for the prior year, and its article 11 requires keeping the advanced electronic signature current, an active tax ID (RFC) and a positive tax compliance opinion from the Mexican Tax Administration Service (SAT).
The consequences of a cancellation are serious. As IDC Online explains, the company must change its customs regime or return abroad the temporarily imported inputs, parts, components and fixed assets within 60 calendar days after notification. In practice, that can mean paying import taxes on inventory and machinery, or shutting down production lines.
The U.S. context
Internal compliance matters even more when the tariff environment keeps shifting. On October 1, 2026, El CEO reported that tariff negotiations between Mexico and the United States are in their final stage, according to Deputy Minister for Foreign Trade Luis Rosendo Gutiérrez, and that Mexico is seeking to lower the tariff on cars to 15%, in line with the rate applied to Japan and Korea. For auto parts, according to the same report, no changes to rules of origin are expected.
For an exporter, this means a product's cost can change from one month to the next depending on how the negotiation ends. If the company also loses its IMMEX program, the blow compounds.
What it means for your company
- Compliance calendar. IMMEX obligations have fixed dates every year. If they depend on a single person or on an outside agent with no oversight, the risk of missing one is high.
- Up to date tax data. Addresses, RFC, electronic signature and compliance opinion should be reviewed regularly, because any inconsistency can lead to suspension.
- Customer and supplier contracts. Review who absorbs new tariffs, how costs are shared if the rule of origin changes and what happens if one of the parties loses an incentive program. Poorly drafted price adjustment and force majeure clauses often lead to disputes.
- Certification of origin. Keep documentary support showing that your products comply with the trade agreement. That is what backs preferential tariff treatment in an audit.
An IMMEX program can be lost over a single unfiled report, but the effects reach inventory, machinery and customer contracts.
What to do now
- Check the lists published in the DOF to make sure your program does not appear as suspended or canceled.
- Confirm that the annual report for fiscal year 2025 was filed and keep the filing receipt.
- Build an annual calendar with all ongoing compliance obligations and assign owners.
- Review your export and supply contracts to include clear adjustment clauses for tariffs and regulatory changes.
