To Our Customers,

We are committed to keeping you updated on the Mexican Tax Authority (SAT) Carta Porte requirement for goods moving to and from Mexico. Please refer to the following timelines and updates.

Reminder of Current Timeline
Mandatory Carta Porte requirements have been in place since January 1, 2022.

Beginning January 1, 2024, shipments moving into, out of, or within Mexico with missing or incorrect Carta Porte information, will be subject to penalties from the Mexican government (SAT).

Two additional Carta Porte fields will be required for compliance beginning January 15, 2024. These additional fields are:

  1. MHP – Mexico Hazardous Packaging Code (Tipo Embalaje) Qualifier
    Required on all hazardous loaded and residue last-contained shipments with an origin or destination within Mexico.
  2. MPC – Mexico Unit Packaging Code (Clave Unidad) Qualifier
    Required on all loaded and revenue empty shipments with an origin or destination within Mexico. Also required on all residue last-contained hazardous with an origin or destination within Mexico.

Union Pacific will begin validating the two new fields on October 15, 2023, in addition to our current compliance checks.

Updated EDI Supplement Available
The latest version of the Carta Porte EDI Supplement is now available to comply with the EDI standards.

SAT provided an updated MTC (Customs Tariff Code [Fracción Arancelaria]) file with 53 additional values with an effective date of July 1, 2023. Please review this file on the SAT website to ensure you are supplying the appropriate value in your bill of lading.
