Tariff in United States history
Tariffs have historically served a key role in the trade policy of the United States. Their purpose was to generate revenue for the federal government and to allow for import substitution industrialization (industrialization of a nation by replacing imports with domestic production) by acting as a protective barrier around infant industries.[1] They also aimed to reduce the trade deficit and the pressure of foreign competition. Tariffs were one of the pillars of the American System that allowed the rapid development and industrialization of the United States. The United States pursued a protectionist policy from the beginning of the 19th century until the middle of the 20th century. Between 1861 and 1933, they had one of the highest average tariff rates on manufactured imports in the world. However American agricultural and industrial goods were cheaper than rival products and the tariff had an impact primarily on wool products. After 1942 the U.S. began to promote worldwide free trade, but after the 2016 presidential election has gone back to protectionism.[2]
According to Dartmouth economist Douglas Irwin, tariffs have served three primary purposes: "to raise revenue for the government, to restrict imports and protect domestic producers from foreign competition, and to reach reciprocity agreements that reduce trade barriers."[3] From 1790 to 1860, average tariffs increased from 20 percent to 60 percent before declining again to 20 percent.[3] From 1861 to 1933, which Irwin characterizes as the "restriction period", the average tariffs increased to 50 percent and remained at that level for several decades. From 1934 onwards, which Irwin characterizes as the "reciprocity period", the average tariff declined substantially until it leveled off at 5 percent.[3]
Colonial Era to 1789[edit]
In the colonial era, before 1775, nearly every colony levied its own tariffs, usually with lower rates for British products. There were taxes on ships (on a tonnage basis), import taxes on slaves, export taxes on tobacco, and import taxes on alcoholic beverages.[19] The London government insisted on a policy of mercantilism whereby only British ships could trade in the colonies. In defiance, some American merchants engaged in smuggling.[20][21]
During the Revolution, the British blockade from 1775 to 1783 largely ended foreign trade. In the 1783–89 Confederation Period, each state set up its own trade rules, often imposing tariffs or restrictions on neighboring states. The new Constitution, which went into effect in 1789, banned interstate tariffs or trade restrictions, as well as state taxes on exports.[22]
