tariff

tariff, tax on imported and, more rarely, exported goods. It is also called a customs duty. Tariffs may be distinguished from other taxes in that their predominant purpose is not financial but economic—not to increase a nation's revenue but to protect domestic industries from foreign competition. For that reason, protective tariffs, as they are often called, are opposed by advocates of free trade. See also protection.
