Freight transport

Freight transport is the physical process of transporting commodities and merchandise goods and cargo.[1] The term shipping originally referred to transport by sea but in American English, it has been extended to refer to transport by land or air (International English: "carriage") as well. "Logistics", a term borrowed from the military environment, is also used in the same sense.
