REMINDER - BNSF Enforcement of New Carta Porte Logic

Jan 16, 2024

As a reminder, the Mexico Hazardous Packaging Code (MHP) and Mexico Unit Packaging Code (MCP) are now required on hazardous shipments to/from Mexico. As previously communicated, these additional requirements are a part of the Mexican Tax Authority’s (SAT) new Carta Porte compliance rules enforced on January 1, 2024. 

BNSF systems are accepting the additional Carta Porte information via Electronic Data Interchange (EDI) as well as in our Shipping Instructions application. More information about Carta Porte requirements can be found in the AAR Carta Porte Supplement. Please reference the BNSF General Shipping Instructions and Routing Materials to assist in adding Carta Porte information. If you have questions about Carta Porte, please get in touch with your BNSF marketing representative or BNSF Customer Support via Message Us or call (888) 428-2673 (when prompted, say “Mexico Customs”).
