The shipping, transport, storage, and delivery industry is an essential part of the economy’s infrastructure. The industry contributes more to GDP than the manufacturing of computers, electronic parts, electrical equipment, and appliances.
Transport and shipping companies are responsible for delivering more than half of wholesale goods and more than one-third of retail goods. It also is the only industry in which private companies compete with a federal enterprise endowed with special rights and subsidies, the U.S. Postal Service (USPS).
