Reminder - Carta Porte Enforcement To Begin August 1, 2023

Apr 20, 2023

As previously communicated, the Mexican Tax Authority (SAT) will begin enforcing the new Carta Porte Rules on August 1, 2023. The Carta Porte requirements mandate additional waybill information on shipments moving to Mexico, including commodity description, package type and quantity for each product. The specific requirements can be found in the AAR Carta Porte Supplement.

In preparation for the enforcement date, customers subscribed to receive waybill notifications will be notified if their shipment is missing Carta Porte information. To subscribe to waybill notifications, please go to > log into the Customer Portal > click on the “My Apps” circle > “Subscription Center” > select the dropdown arrow next to Waybill Exceptions > and choose the 633s for which you would like to receive notifications.

If you have questions about Carta Porte, please contact your BNSF Marketing Representative or BNSF Customer Support via Message Us or call (888) 428-2673 (when prompted, say “Mexico Customs”).
