On July 28, 2025, the Mexican Tax Authority, commonly referred to as SAT, published an amended Resolution of Modifications to the General Rules of Foreign Trade for 2025, which changes the rules for goods imported by courier under the simplified regime, as well as for goods imported under the United States-Mexico-Canada Agreement (USMCA).

Key Tariffs Changes

Under the amended tariff rules, from August 15, 2025, goods valued at up to USD 2,500 imported by courier under the simplified regime are subject to an increased tariff of 33.5%. This is a significantly higher tariff rate compared to the previously applicable rate of 19%.

Additionally, goods imported into Mexico under the USMCA regime whose value exceeds USD 117, or its equivalent in national or foreign currency, are subject to a 19% tariff. However, the application of this tariff is conditional on two factors. These two conditions require that the shipment must be covered by an air waybill or a bill of lading, and the goods must not be subject to non-tariff regulations or restrictions such as health, safety, or environmental compliance requirements.

The amended tariffs particularly affect businesses involved in international trade and e-commerce, including courier companies, importers, and consumers. While courier companies must adapt their systems to accurately classify shipments and apply the appropriate rates based on value and eligibility, importers and consumers will be affected by the tariffs, primarily depending on the country from which the goods are imported.

For e-commerce businesses and platforms, this may add additional compliance requirements, as they must work closely with courier companies to ensure that goods are cleared in customs under the correct regime.

Conclusion

The amended tariff rules maintain the established global tariff rate, now set at 33.5%, for most shipments and establish a new preferential rate of 19% for certain goods that meet specific conditions, such as being imported under the USMCA regime and valued at over USD 117, among others. Both importers, courtier companies, and e-commerce businesses must assess how these tariffs affect their business operations and take appropriate action accordingly.
