Shipping has multiple meanings. It can be a physical process of transporting commodities and merchandise goods and cargo, by land, air, and sea. It also can describe the movement of objects by ship. Land or "ground" shipping can be by train or by truck. In air and sea shipments, ground transportation is required to take the cargo from its place of origin to the airport or seaport and then to its destination because it is not always possible to establish a production facility near ports due to limited coastlines of countries. Ground transportation is typically more affordable than air shipments, but more expensive than shipping by sea especially in developing countries like India, where Inland infrastructure is not efficient.
