Mexico’s customs and foreign trade legal framework has evolved toward a stricter and more controlled compliance model.
Mexico’s tax authority (Servicio de Administración Tributaria – SAT) has postponed the mandatory implementation of the Electronic Value Manifest (Manifestación de Valor Electrónica – EVM). The requirement is now expected to become mandatory on June 1, 2026.
AI is now deeply embedded in the internet and social media, producing everything from humorous content and realistic simulations to advanced automation. These capabilities have expanded beyond entertainment and productivity, reaching into areas of public administration and government oversight. This raises a critical question: if AI is transforming nearly every sector, how will it reshape tax and customs compliance, and how will it be regulated?
Mexico’s customs and foreign trade legal framework has evolved into a substance-based compliance model. Authorities now expect importers to demonstrate not only what was imported, but also why, under what legal relationship, and under what economic terms the transaction took place.
On November 19, 2025, a Decree amending, adding and repealing various legal provisions of the Mexican Customs law was published in the Diario Oficial de la Federacion (Mexican Official Gazette). This reform will enter into force on January 1, 2026. Although the Customs Law has been amended multiple times in the last 30 years, this reform is widely considered the most significant since December 15, 1995.
The development of a tequila brand begins with a foundational step: registering a trademark in Mexico, the United States, or any other intended markets. However, trademark protection is only the starting point. Building a tequila brand requires a broader business and regulatory strategy involving multiple teams—Customs and trade, finance, marketing, and legal—to plan for production, cost structures, distribution, sales, and export-related compliance.
Beginning December 9, 2025, importers in Mexico will be required to complete and submit the Electronic Value Manifest through VUCEM (Mexico’s Electronic Single Window). This measure increases the importer’s direct participation and responsibility in determining and declaring the correct customs value of imported goods.
The steel trade with Mexico is particularly strategic at this moment. Companies are shifting supply chains to North America, and Mexico which has been an attractive manufacturing hub for various industries, such as automotive, aerospace, construction, electronics, household appliances, and more. This trend is driving strong demand for imported steel while simultaneously creating new export opportunities for Mexican producers. Much of this advantage stems from the USMCA, because steel originating within the USCMA region can qualify for preferential tariff treatment when traded within the United States and Canada, provided that the applicable rules of origin are fully met.
From a Mexican resident’s perspective, who is also involved in international trade, it appears that since the Trump administration took office, the global economic scenario has been altered by an escalating trade war, characterized by the imposition of tariffs by the U.S. government, on a range of countries. These measures, intended to safeguard the U.S. interests, have affected the relationships with certain international markets, as the U.S. is showing signs of progressive isolationist practices.
My internship in Mexico was with the Servicio de Administración Tributaria (SAT), the office responsible for applying tax and customs legislation, which facilitates trade through customs administration. With its influence extending across both the public and private sectors, SAT stands at the forefront of Mexico’s efforts to promote transparency, efficiency, and fiscal responsibility. My internship experience within this institution offered invaluable insights into its operations and the impact it has on the nation’s economic landscape.
