Exports to Mexico by Rail

Buckland has received the following notice regarding exports to Mexico by rail. While there has been no change to regulations, there has been an increased focus on enforcement. We are sharing this with you to ensure that you are aware of the most relevant and up to date information on this matter.


All exports from US to Mexico are required to have a complete ITN (Internal Transaction Number) if the value is higher than $2,500 USD of one HTS (Harmonized Tariff Scheduled) codes of the merchandise. In the past, US exporters and Mexican importers may not have followed this direction, however it is now being enforced more rigorously.

Also, with the coordination of CBP (US Customs and Border Protection) and Mexican Customs Servicio de Administración Tributaria (SAT), CBP is inspecting more loads going southbound. If your container does not have an Automated Export System (AES) Electronic Export Information (EEI) properly completed, the probabilities of inspections will be much higher. This can result in delays ranging from hours or days and can lead to charges for inspections, devanning, storage fees, etc.

Buckland highly recommends that the EEI is completed at the moment the container is picked up from your vendor, and that the EEI is updated with the export date once exported. The CBP is also enforcing the compliance on the data in the EEI, with information such as Schedule B (HTS for exports), descriptions, related parties, etc. It is very important to mention that the forwarder that is doing your EEI as USPPI (US Principal Party in Interest) or FPPI (Foreign Principal Party in Interest) or in a routed transaction must have POA (power of attorney) from either of the parties involved in the transaction.


If you have rail shipments going in to Mexico please send your documents to southbound@buckland.com to make sure the EEI is properly completed, or contact our Customer Service Administration team at csausgroup@buckland.com.
