What is Carta Porte:
The Carta Porte is a Mexican tax receipt for merchandise being transported and will soon replace the standard transfer invoice and logistics letter.
Changes to the Carta Porte, as mandated by the Mexican Tax Authority, were recently announced. This new requirement was issued by the Servicio de Administración Tributaria, also known as the SAT. The new Carta Porte requirements will be effective January 1, 2022, for all modes of transportation on any cross border and/or Mexico domestic shipments; this includes rail, truck, water, and air.
The first requirement was effective on December 1, 2021, and pertained to Freight All Kinds (FAK). On December 1, 2021, anything shipped with the commodities listed as Freight All Kinds would not be accepted.
The second requirement will be effective on January 1, 2022. This change requires shippers to include new fields on the EDI-generated Bill of Lading and shipping documents. Shippers will be required to provide additional information for any import, export, or Mexico domestic shipments. These fields include:
- SAT Commodity Code
- Customs Tariff Code
- UN/NA Identification Code (hazmat only)
- Universal Unique Identifier (Mexico origins only)
- Commodity description
What do I need to do:
If you are wondering what you need to do to be compliant with the upcoming changes, here are some helpful tips.
To ensure there will not be any delays with your goods, and that all the shipping documentation is accurate, you will need to have the newly required information correct prior to shipping.
We recommend connecting with your customers, and your Mexico brokers to obtain the required information. Failure to provide the newly required information may result in delayed shipments and penalties on the Mexican portion of the shipment, so we recommend implementing this as soon as possible.
Here are the newly required fields and how to obtain this information.
SAT Commodity Code
Work with your Mexican Customs Broker(s) to obtain the required SAT code.
Customs Tariff Code
While similar to the Harmonized Schedule tariff Code, this code will have a different number and format. Work with your Mexican Custom Broker(s) to obtain the required Customs Tariff Code.
UN/NA Identification Code (Hazmat Only)
The UN number is a four-digit code that identifies hazardous materials. This number can be found on your Safety Data Sheet (SDS) and/or the Code of Federal Regulations (CFR) Title 49.
Universal Unique Identifier (Mexico Origins Only)
The Universal Unique Identifier (UUID) is a 36-character number provided by the Mexican SAT Authorities. The SAT generates the UUID, which be obtained from your Mexican Customs Broker(s).
FAK (Freight All Kinds) is no longer accepted by the SAT, effective December 1st, 2021. Ensure you have an updated commodity description for your rail freight.
Here is an example of the newly required fields.
