Carte Porte - Mexican Tax Authority Waybill update #3 – new date

September 29, 2021

We are pleased to share that the Mexican Tax Authority (SAT) has delayed the implementation of the Carta Porte changes until December 1, 2021 from its original September 30, 2021 date.

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.  

KCSM is continuing to work on adapting our systems to be ready by the newly established date of December 1, 2021, as set by the Mexican government.   

As a reminder and to ensure all our customers and partners continue working toward the required changes, we have outlined them again below.
Customers should be prepared to provide the following information from the Carta Porte Products Reference File (Catálogo de productos carta porte) as issued by the Mexican Tax Administration Service (SAT): 

  •  For all traffic:
  1.  Commodity code (Clave Producto)
  2.  Hazmat code (Clave de Producto Peligroso) and Packing type (Clave de Designación), if applicable
  •  For exports, customers will also need to provide the following: 
  1.  Customs Pedimento (export manifest or Pedimento de Exportación)
  2.  UUID from CFDI supporting the international sales of goods 
  3.  Customs Tariff Code (Fracción Arancelaria)
  •  For imports, customers will also need to provide the following: 
  1.  Customs Pedimento (import manifest or Pedimento de Importación)
  2.  Custom Tariff Code (Fracción Arancelaria)  

The Carta Porte changes are mandatory for all shipping companies in Mexico as established by the Mexican government. Therefore, these supersede any provision to the contrary that may exist in any rule, tariff, rate or contract previously published or entered by KCSM, including special invoicing. These changes will result in a significant increase in the number of customer invoices. As a result, KCSM will no longer be able to accommodate customer requests to upload invoices or perform other non-standard invoice processes.   

We continue to work with the Mexican authorities to determine if any additional data from the shipper is necessary beyond those listed above. 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 is no risk of delayed shipments or additional fees or penaltiesi.

Shippers shall be responsible at all times for the accuracy of the information provided by them or by their representatives (i.e. custom brokers) to KCSM and to the tax and customs authorities.   

Should you have any questions on this mandate, please don’t hesitate to contact our KCSM Customer Solutions team 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 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.
