Carta Porte #24 - KCS halting some hard EDI validations due to SAT changes

December 19, 2022

Attention EDI users,

We previously communicated that valid Carta Porte data would be required in your EDI 404 transmission and missing or erroneous Carta Porte data would result in waybill rejections by KCS as of November 1st, 2022. We have just been informed that the SAT has modified some of the Mexico tariff rate codes as of December 12, 2022.  

In an effort to allow our customers to have the necessary time to update their systems to reflect the revised tariff rate codes and therefore be compliant with the Mexico government’s regulations on Carta Porte, we have temporarily suspended hard validations for waybills including the impacted tariff rate codes. We will turn back on hard validations for the impacted tariff rate codes as of Tuesday, January 31, 2023.   

A comprehensive list of all Mexico Rate Tariffs can be found here. For a list to validate if your Tariff Rates have changed, please visit here. 

If you are unable to have your system ready by Tuesday, January 31, 2023, you should be prepared to create your waybills via MyKCS until you are able to complete the updates to your EDI system.  

All Carta Porte content, updates, dates, training material, links to resources and communications can be found on the dedicated Carta Porte page in our Rail Resource Center on our website. 

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.  

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 setout costs, detentions, penalties and fines determined by the tax and customs authorities.
