shipping
Shipping lines, airlines and freight forwarders perform, at the request of shippers, many services relating to the transfer, storage, and documentation of freight destined for export. The same is true of imports. Some carriers have a tariff on such traffic, which sets forth a rate covering the air transportation from airport of origin to seaport and all relevant transfer and documentation procedures. On freight arriving in the United States, via an ocean vessel and having a subsequent movement by air, some airlines have a similar tariff program known as “Import Service.”.
