Sea land intermodal transportation refers to a transportation method in which two modes of transportation, sea transportation and land transportation, are successively connected. The goods are transported from the place of origin to the destination, with a portion completed by ships transporting them by sea and another portion completed by vehicles transporting them by land (including trains or cars), and a full distance intermodal bill of lading is issued by a carrier. It is called sea land intermodal transportation.
For example, if goods from the East Coast of the United States are to be exported to Shanghai, they are first transported by train to ports on the West Coast, and then by sea to Shanghai, China, which is known as land sea intermodal transportation.
