Carta Porte - Mexican Tax Authority Waybill update #7 – New updates and clarifications

December 23, 2021

In our commitment to keeping you updated on the Carta Porte program in Mexico, this communication is to provide recent updates and clarifications for the Carte Porte program in Mexico. There are several updates noted below.  

January 1st implementation date remains 
Per the SAT mandate, KCS will be requiring all shippers in Mexico to adhere to the new SAT commodity codes and requirements of this program as of January 1, 2022. We will be working closely with our customers to be ready to meet the requirements as of January 1st.i 

Carta Porte Solution Tools: 
KCS is working diligently to enable our customers to leverage both EDI and MyKCS to facilitate a seamless transition to the Carta Porte program. As of January 1, 2022, Customers can leverage either MyKCS or EDI version 5010 or higher to meet the criteria for Carta Porte documentation. For MyKCS customers, it should be noted that there will be several phases with incremental functionality. Phase 1 (Jan 1, 2022), you may add or view waybills but may not edit or delete once submitted. The ability to modify or delete is planned for Phase 2 which is planned for mid-Q1-2022.  We will communicate this when the phase is ready to be implemented.

FAK (Freight of all Kind) shipments:
We are pleased to inform you that FAK shipping may continue within Carta Porte with the following caveats:

  • MyKCS:  MyKCS users will be provided a new screen that will require the Carta Porte information to be added including the SAT codes for the “FAK shipment”.
  • EDI: EDI customers using version 5010+ can enter in the FAK shipment code and provide the SAT code detail within EDI, as well. For additional information related to the Tariff Rate Code(s) please click here. For any other EDI questions, please contact the EDI Support team for assistance.  

Southbound:  We are still pending clarification if a pedimento is still required for all southbound cross-border traffic. Until we have this clarification, the pedimento should be entered into the waybill prior to entering the requirements for the Carta Porte.  

Northbound: According to standard Carta Porte v2.0, a pedimento number is not a mandatory data element for Northbound Cross-border Traffic. The MX Customs Clearance (Despacho) process will continue working through Rail Manifest (VUCEM) the same way it works today. 

UUID codes:  
Per the SAT, UUID codes remain mandatory for all northbound, cross-border traffic exported from Mexico using an A1 Pedimento. This can be entered by EDI or MyKCS.  

Expanded Support:
In an effort to provide the support that may be needed for seamless shipping, KCS will be offering expanded customer support from January 1, 2022, through January 14, 2022. Look for more details on this to come. 

As a reminder, the Carta Porte requirements apply to all shipping companies (cargo airlines, trucks, maritime, railroads, etc.). This applies to cross-border, international, and Mexican 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.  

As a reference, KCS created a Mapping tool to facilitate the translation of STCC code to the required SAT Commodity Code. Unless communicated otherwise or transmitted through EDI, this is the “logic” that will be used for STCC to SAT commodity codes.  

You have our commitment to continuing working with both the Mexican authorities as well as our shipping partners to ensure you are made aware of any updates to this project that may impact your future cross-border shipping. As we learn more, we will share this information with you.   

Should you have any questions on this program, 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.

i 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, 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 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.
