For tax purposes, all Mexican importers must register and be listed with the Official Register of Importers (Padrón de Importadores), maintained by the Secretariat of Finance and Public Credit (Secretaría de Hacienda y Crédito Público or SHCP), which also maintains special sector registries. To be eligible to import more than 400 different items (including agricultural products, textiles, chemicals, electronics, and auto parts), Mexican importers must apply to the SHCP to be listed in these sector registries. U.S. exporters have occasionally encountered problems when products are added to the list without notice or importers are summarily dropped from the registry without prior notice or subsequent explanation. It is important to keep in mind that, in many cases, releasing goods from Mexican customs can take more time than expected.

The basic Mexican import document is the Customs Declaration Form for customs clearance (Pedimento de Importación). Mexico requires import and export documentation including a completed pedimento for all commercial crossings. This document must be accompanied by a commercial invoice (in Spanish), a bill of lading, documents demonstrating guarantee of payment of additional duties for undervalued goods, if applicable, and, if applicable, documents demonstrating compliance with Mexican product safety and performance regulations (see the Standards for Trade section).

Mexican importers and exporters can dispatch their goods through an authorized legal representative who meets certain technical requirements and who has a certain degree of experience. Mexican customs brokers can clear products through Mexican Customs, but keep in mind that Mexico’s customs regulations are very strict and require total compliance with all requirements by official importers. All commercial imports into Mexico, whether they are temporary or permanent, can be executed by a qualified and authorized Mexican customs broker.

Products qualifying as North American under the United States-Mexico-Canada Agreement (USMCA) require a minimum set of nine data elements be submitted to prove origin and receive USMCA preferential tariff treatment. This certification may be issued by the importer, exporter, or producer, and it does not have to be validated or formalized. Contact the U.S. Commercial Service Mexico for an example of these data elements.

Mexican tax authorities conduct fiscal audits on certain exporters in sensitive industries. A good source of information is the Mexican Tax Administration Service’s (Servicio de Administración Tributaria or SAT) website regarding Verification of USMCA Certification of Origin. Between 2019 and 2020 the number of site verifications and audits conducted by Mexican authorities at U.S. plants appeared to increase. If your company faces such an audit or inspection, please contact the U.S. Commercial Service Mexico.
