On May 1, 2021, the Tax Administration Service (SAT by its Spanish acronym), published on its website the electronic document called Complemento carta porte (Carta Porte) or Bill of Lading supplement.

The Carta Porte is a collection of over 120 data elements, which includes:

  • Shipper information
  • Consignee information
  • Cargo and its value
  • Carrier equipment
  • Driver information
  • Routes taken (within Mexico)
  • Regulatory information
  • And more...

The regulations were put into effect January 1, 2022, with enforcement (penalties for non-compliance) beginning March 31, 2022. It was put into place to help combat issues that SAT has had for years with tax evasion through the smuggling of goods without payment of the corresponding Mexican taxes.

This requirement will be applied to all importation and exportation of goods in transit within Mexican territory. The Carta Porte is required only for the movement within Mexico.

The shipper will be expected to provide the required information in advance of the shipment being picked up. For Averitt customers, this process will be coordinated by our Cross-Border Team.

Pickup of shipments without the required information to allow the carrier to issue the Carta Porte, where applicable, will be delayed until the information is received. In the event of non-compliance, Carta Porte regulations establish significant fines and penalties for the carrier.

Averitt's Cross-Border Team (LTL and TL) will coordinate with the appropriate party to obtain the information required for each carrier, as a part of the pickup process. The Cross-Border Team has access to each of our Mexican partner carrier’s Carta Porte documentation.

If you are a current or prospective Averitt customer, any questions or concerns regarding this new regulation can be directed to our Cross-Border Team (
