Tariff
A tariff is a tax on imports or exports between sovereign states. It is a form of regulation of foreign trade. It is a policy that taxes foreign products to encourage or protect domestic industry. It helps limit trade deficits. The tariff is historically used to protect infant industries and to allow import substitution industrialization.
Tariff in United States history
Tariffs up to the Smoot–Hawley Tariff Act of 1930, were set by Congress after many months of testimony and negotiations. In 1934, the U.S. Congress, in a rare delegation of authority, passed the Reciprocal Tariff Act of 1934, which authorized the executive branch to negotiate bilateral tariff reduction agreements with other countries. The prevailing view then was that trade liberalization may help stimulate economic growth. However, no one country was willing to liberalize unilaterally. Between 1934 and 1945, the executive branch negotiated over 32 bilateral trade liberalization agreements with other countries. The belief that low tariffs led to a more prosperous country are now the predominant belief with some exceptions. Multilateralism is embodied in the seven tariff reduction rounds that occurred between 1948 and 1994. In each of these "rounds", all General Agreement on Tariffs and Trade (GATT) members came together to negotiate mutually agreeable trade liberalization packages and reciprocal tariff rates. In the Uruguay round in 1994, the World Trade Organization (WTO) was established to help establish uniform tariff rates.
