On July 14, 2021, the Government of Mexico published in its Official Gazette a decree announcing the creation of a new National Customs Agency (ANAM) under Mexico’s Secretariat of Finance and Public Credit (Secretaría de Hacienda y Crédito Público or SHCP).  Previously, customs related functions were overseen by Mexico’s Tax Administrative Service (Servicio de Administración Tributaria or SAT). This decree did not take effect immediately.  Further legislative reforms are required to execute this change. For the time being, foreign trade operations will continue to be handled by Mexican Customs via SAT.  However, additional legal, administrative, and operational changes are expected as this reorganization is implemented. 

Some U.S. exporters have expressed concerns about SAT procedures. These include insufficient prior notification of procedural changes, inconsistent interpretation of regulatory requirements at different border posts, and uneven enforcement of Mexican standards and labeling rules. SAT has made efforts to increase transparency and communication and reduce corruption and fraud.

Agricultural exporters note that Mexican inspection and clearance procedures for some agricultural goods can be long, burdensome, non-transparent, and unreliable.

Customs procedures for express packages continue to be burdensome. Under the United States-Mexico-Canada Agreement (USMCA), Mexico amended its General Foreign Trade Rules modifying its “tasa global,” a combination duty and charge on all shipments entering under simplified clearance (de minimis and informal entry) methods, including shipments from the United States and Canada. Goods coming from the United States valued at USD 50 or less will not be charged duties or taxes. Goods valued from USD 50 to USD 117 will be charged a 17 percent tax, but will not be charged duties.
