Once again, I wouldn't get too picky with the semantics:
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.
Shipment of cargo by trucks, directly from the shipper's place to the destination, is known as a door to door shipment and more commonly multimodal transport system. Trucks and trains make deliveries to sea ports and air ports where cargo is moved in bulk.
So, those in the business may like to be called "carriers" the term "shipper" has been used by the "carriers" themselves to describe their business.
But, I certainly agree that good packing is certainly mandatory for the best odds of a trouble free shipment. But, that doesn't mean even the best packaging couldn't be mis-handled to the point that the merchandise is damaged. Of the three I have used, FedEx, UPS, and the USPS, UPS is by far the worst. I gave them 6 years to change personnel and procedures but the results were still the same. We will have to wait and see if they give me any problems with the insurance claim...
