Announcement Number: CN2024-3
Categories: General Announcements
Posted Date: January 25, 2024

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.

Timeline Reminder
Since January 1, 2024, shipments moving into, out of, or within Mexico with missing or incorrect Carta Porte 2.0 information, have been subject to penalties from the Mexican government. To help customers avoid these fines from being applied by the Mexican government, Union Pacific has been notifying customers of any non-compliant bill of lading submission and requiring corrections prior to moving cars.

Additionally, SAT requires the following two Carta Porte fields for compliance. Union Pacific will be adding these two new fields to our current compliance checks beginning March 1, 2024.

  • 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.
  • 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.
