Carta Porte - Mexican Tax Authority Waybill update #6 - Deadline extension

November 30, 2021

In our commitment to keeping you updated on the Carta Porte program in Mexico, this communication is to share that the Mexican Tax Authority (SAT) has extended the effective date for the Carta Porte program implementation from December 1, 2021 to January 1, 2022.   

KCS, along with many customers, participated in a meeting with the Mexican Secretary of Finance to provide feedback and context on the complexity of implementing this program in the timeframe allotted.  Ongoing dialogue and meetings are planned to continue to share challenges faced by shippers and transportation providers alike with this complex program.  

As a reminder, the Carta Porte changes apply to all shipping companies (cargo airlines, trucks, maritime, railroads, etc.). This applies to cross-border, international and Mexico domestic shipments. This supersedes any provision to the contrary that may exist in any rule, tariff, rate or contract previously published or entered by KCSM, including special billing.  

Summary of previous Carta Porte communications: 

  • Please refer to the Mapping tool KCS created to facilitate the translation of STCC code to the required SAT Commodity Code.  
  • FAK (Freight of all Kinds) STCC code will not be accepted as part of the Carta Porte program.  Please see Mapping Tool for the most appropriate SAT Commodity code.    

We continue to work with the Mexican authorities to determine if any additional data from the shipper is necessary beyond what has been previously communicated. As we learn more, we will share this information with you.   

KCSM 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 KCSM to issue the bill of lading (Carta Porte) and the invoice, prior to the provision of the freight rail transportation service. 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 penalties1.

Should you have any questions on this mandate, please don’t hesitate to contact our KCSM Customers Solutions Center or your Sales Account Executive who will be happy to answer your questions.  

Thank you for being a loyal Kansas City Southern customer and we look forward to continuing to serve you.

1Shippers will reimburse and indemnify KCSM 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 KCSM by them or by their representatives, including without limitation, for any detentions, penalties and fines determined by the tax and customs authorities.
