Posted Date: February 7, 2024

To Our Customers,

The Mexican Tax Authority (SAT) will launch additional field requirements as part of Carta Porte 3.0 beginning on April 1, 2024. As previously announced, Carta Porte 2.0 requirements became effective on January 1, 2024, for shipments moving into, out of, or within Mexico.

Requirements for Carta Porte 3.0 – Effective April 1, 2024
Beginning on April 1, three additional fields will be required for Carta Porte compliance. Union Pacific is currently working to capture the following date fields within our Electronic Data Interchange (EDI) and Waybill Management platforms. We plan to have our systems ready to accept these new values the week of March 4, 2024, and will send a follow-up communication when our systems can accept the new fields. Please familiarize yourself with these requirements and be ready to provide these additional fields to avoid penalties from the Mexican government.

  • Mexico Material Type (Tipo Materia) Qualifier (N9*MMT)
    Required on all loaded, revenue empty and residue last-contained hazardous shipments with an origin or destination within Mexico.
  • Importer Party Loop (N1*IM)
    Required on all loaded southbound shipments crossing the border into Mexico.
  • Importer Taxpayer ID (REF*TJ)
    Required whenever the Importer Party Loop is present.
