Tariffs: A Timeline from the Navigation Acts to the WTO

1651-1776: Navigation Acts and Mercantilist Protection

England’s Navigation Acts, beginning in 1651 and extended repeatedly, required colonial goods to move in English ships and channeled enumerated commodities through English ports. The aim was not primarily revenue but control: securing shipping capacity, protecting domestic manufacture, and denying trade to Dutch and French rivals. Similar systems operated across the European colonial powers. For American colonists these restrictions became a political grievance well before independence, and disputes over duties — the Sugar Act of 1764, the Townshend duties of 1767, the Tea Act of 1773 — helped push the colonies toward revolution. Trade taxation and political legitimacy have been entangled from the beginning.

1789-1833: Revenue, Protection, and the Nullification Crisis

The Tariff Act of 1789 was among the first laws passed by the new United States Congress, signed on July 4 of that year, and for most of the nineteenth century customs duties were the federal government’s principal source of revenue. Protection soon became sectional. The 1828 tariff, denounced in the South as the “Tariff of Abominations,” raised rates sharply and benefited Northern manufacturers at the expense of cotton-exporting states. South Carolina declared it null within its borders in 1832, President Andrew Jackson responded with the Force Bill, and the confrontation was defused by the Compromise Tariff of 1833, which scheduled gradual reductions.

1846-1860: Britain Turns to Free Trade

Britain’s Corn Laws restricted grain imports and kept bread prices high, transferring income to landowners. The Anti-Corn Law League, led by Richard Cobden and John Bright, built an unusually effective national campaign against them, drawing directly on Ricardian arguments. Prime Minister Robert Peel secured repeal in 1846 at the cost of splitting the Conservative Party. Britain moved steadily toward open trade thereafter, and the Cobden-Chevalier Treaty of 1860 with France cut duties on both sides and introduced most-favored-nation clauses that spread reductions across Europe. It was the high-water mark of nineteenth-century liberal trade policy.

1930-1934: Smoot-Hawley and the Reversal

The Smoot-Hawley Tariff Act, signed in June 1930 and named for Senator Reed Smoot and Representative Willis Hawley, raised U.S. duties on a long list of imports as the Depression deepened. More than a thousand economists petitioned President Hoover to veto it. Trading partners retaliated, and world trade contracted sharply over the following years — economists debate how much of that contraction the tariff itself caused versus the collapse in demand, but the act is a standard cautionary example. The Reciprocal Trade Agreements Act of 1934 reversed direction, delegating authority to the President to negotiate mutual tariff reductions, a template that shaped everything after.

1947-1995: From GATT to the WTO

Twenty-three countries signed the General Agreement on Tariffs and Trade in 1947, establishing non-discrimination through most-favored-nation treatment and a framework for successive negotiating rounds. The Kennedy Round of the 1960s and the Tokyo Round of the 1970s cut industrial tariffs substantially. The Uruguay Round, launched in 1986 and concluded in 1994, extended rules to services, intellectual property, and agriculture, and created the World Trade Organization, which began operating in 1995 with a binding dispute settlement system. Regional agreements ran in parallel: NAFTA entered into force in 1994 and was replaced by the USMCA in 2020.
