What are in-bond shipments?

In simple terms, in-bond loads are those that are stored or transported through the United States but are not intended to be commercialized in that country, so they do not clear customs in the US border.  In other words, the in-bonded shipment may be transported and stored in the United States without having to pay duties, taxes or customs costs related to the import process. The in-bond cargo must be transported by a bonded carrier and, if applicable, be stored in a bonded warehouse in the United States.

If the shipment requires to be transported through two points within the United States in order to be exported to a different country, a Transportation and Exportation Bond or T & E is required.

When the shipment is transported between two points of entry within the customs territory of the United States to enter the destination port, an Immediate Transportation Bond (IT) is required.


Example 1. An LTL shipment that leaves Mexico and that is transported by land through the United States to be exported to Canada.

Example 2. An FTL shipment that is transported by land in a reefer from Laredo to an international airport within the United States, such as Houston, to be transported by plane to Europe.

Example 3. A Dry Van that leaves Laredo and is transported by land to a seaport in Miami, to be sent by sea to Europe.

What is the customs bond?

The customs bond is a form of insurance to protect the United States in the event that an importer or exporter does not pay the duties, taxes or fines incurred in their imports.
