Transit freight transportation refers to the process of moving goods from one country to another through the territory of a third country without being subject to customs procedures. In more detail, it is the temporary suspension of customs duties or restrictions on a shipment, allowing the cargo to enter a country by land or sea, pass through its territory, and exit again via another land or sea border.

Today, transit transportation may involve a single mode of transport or include multimodal (combined) transportation systems where different transportation methods work together efficiently to complete the logistics operation.
