Carta Porte Grace Period Extended for Mexico Shipments

Announcement Number: CN2022-52
Categories: General Announcements
Posted Date: October 4, 2022

To Our Customers,

Mandatory Carta Porte requirements have been in place since January 1, 2022. Since that time, the Mexican government has allowed a grace period with no penalties for non-compliant shipments. The Mexican government has extended this grace period until December 31, 2022. Beginning January 1, 2023, shipments moving into, out of or within Mexico with missing or incorrect information, will be subject to penalties from the Mexican government.

Union Pacific has been notified that KCSM will begin rejecting EDI 404* transmissions with missing or erroneous Carta Porte data beginning November 1, 2022. FXE will begin rejecting EDI 404 and EDI 417** transmissions with missing or erroneous Carta Porte data beginning January 1, 2023.

Union Pacific has begun to audit current EDI submissions for Carta Porte data accuracy. We will be contacting customers to ensure full compliance by December 1, 2022. To avoid delays and subsequent congestion at the border, effective January 1, 2023, Union Pacific will begin rejecting waybills (EDI 404 and EDI 417) for incorrect or missing Carta Porte information. Please ensure your waybill submission is in compliance with Carta Porte requirements, which include the following:

  • Commodity Information (description, quantity, weight, STCC)
  • Customs Tariff Rate
  • Carta Porte Shipper Contact Information
  • Hazardous Commodity Code – Hazardous shipments only
  • Universal Unique Identifier – Northbound traffic only

Document Delay Charges for Carta Porte - Effective January 1, 2023
If you have missing information that delays your shipment from crossing the border, we will assess a charge to hold that car until the required paperwork is received. After the expiration of the applicable processing time, “Document Delay” charges of $300.00 per car per day, or fraction thereof, will be assessed if a rail car is set out at a Union Pacific yard due to customs clearance and/or government legal requirements not being obtained or met.
