Carta Porte #29 – New mandatory fields for Carta Porte 3.0

March 25, 2024

Effective April 1, 2024, the Mexican Tax Authority (SAT) will be enforcing Carta Porte 3.0 requirements for all rail traffic including intermodal, automotive and carload.  

To support our customers in preparation for these changes, we have created training materials located here

In preparation for April 1st, you may begin completing these fields immediately. As a reminder, the fields are; importer party, importer ID and Mexican materials type. If you have questions about the new requirements, please reference the previous Carta Porte communication here. Failure to comply with Carta Porte 3.0 requirements could result in the assessment of penalties issued by the Mexican Tax Authority and customs authorities which may result in fines, possible shipment delays and/or seizure of goods.

Thank you for choosing CPKC. 

CPKCM will not initiate the transport of goods, nor receive them in interchange from other carriers, without having the necessary information from shippers that would allow CPKCM to issue the bill of lading (Carta Porte) and the invoice, prior to the provision of the freight rail transportation service, including any service provided by third parties hired by customers and restrictions imposed by any Mexican Government entity. Our expectation is that our customers are also working to be fully compliant so there will be no risk of delayed shipments or additional fees or penalties. Shippers will reimburse and indemnify CPKCM for any losses and damages caused, as well as for the cost and expenses incurred, as a consequence of the inaccuracy of the information provided to CPKCM by them or by their representatives, including without limitation, for any setout costs, detentions, penalties and fines determined by the tax and customs authorities.
