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.

Modern Tariffs

Those customs duties that are still imposed today are usually either one of two types—specific duty, a tax levied on the quantity, whether by weight, size, or number, of the goods; or ad valorem duty, a percentage of the foreign or domestic price. The ad valorem duty is generally considered to be preferable but more difficult to levy, requiring complex procedures to determine the value of goods. Specific duties are best applied for protectionist purposes, since their size varies inversely with the prices of imports. For example, an import taxed at $5 per ton, and costing $100 per ton, may have an effective duty of 5%. However, if its price drops to $80 per ton—a threat to domestic producers—the effective duty may rise to more than 6%. Certain tariffs are also designed to offset dumping.

History

Evolution of Tariffs

Tariffs have been used by governments since ancient times, although they were originally sources of revenue rather than instruments of state economic policy. Early customs duties consisted of payments for the use of trade and transportation facilities, including ports, markets, streets, and bridges. By the 17th cent., however, they came to be levied only at the boundary of a country and usually only on imports. At the same time, European powers established special low tariff rates for trade with their possessions; such systems of colonial preference formed the basis of the trading patterns that developed in the 17th and 18th cent. (see mercantilism and Navigation Acts).

Although the free trade movement in the early 19th cent. discouraged the use of tariffs, a new system of trade relations known as imperial preference developed in the late 19th cent. Great Britain and France, in particular, used preferential tariffs to organize the flow of foodstuffs and raw materials from their colonial dependencies and to regulate the export of domestic manufactured products into those areas. Other European nations retaliated by raising their tariffs, and a period of relatively high protective tariffs lasting through the Great Depression followed.

Trend toward Free Trade

Since World War II the trend has been away from tariffs and in favor of freer trade. Through instruments such as the most-favored-nation clause and the reciprocal trade agreement, two nations may agree to lower their respective tariff barriers. More comprehensive agreements, such as those of the European Union and other customs unions, lower or even eliminate tariffs among groups of nations. Finally, the General Agreement on Tariffs and Trade (GATT) and its successor, the World Trade Organization (WTO), have since the 1950s sponsored a number of initiatives for lowering the customs duties of most major trading nations. The United States has participated in the movement toward freer trade by lowering its customs duties from the high rates of the Hawley-Smoot Tariff Act (1930); by playing an instrumental role in the several GATT tariff initiatives, including the Uruguay round (1986-93), which created the WTO; and by signing (1992) the North American Free Trade Agreement (NAFTA) with Canada and Mexico.

Payne-Aldrich Tariff Act, 1909, passed by the U.S. Congress. It was the first change in tariff laws since the Dingley Act of 1897; the issue had been ignored by President Theodore Roosevelt. The Republican platform of 1908 pledged revision of the tariff downward, and to this end President Taft called (1909) Congress into special session. The House promptly passed a tariff bill, sponsored by Sereno E. Payne, which called for some reduced rates. The Senate substituted a bill, fathered by Nelson W. Aldrich, which made fewer downward revisions and increased numerous rates. After a sustained attack on the Aldrich Bill by a group of insurgent Republicans in the Senate, a compromise bill was adopted, which somewhat moderated the high rates of the Aldrich bill; the measure was immediately signed by Taft. It lowered 650 tariff schedules, raised 220, and left 1,150 unchanged. Although the Payne-Aldrich Tariff Act was less aggressively protectionist than the McKinley Tariff Act (1890) and the later Dingley Act, it was, nevertheless, protectionist.

Hawley-Smoot Tariff Act, 1930, passed by the U.S. Congress; it brought the U.S. tariff to the highest protective level yet in the history of the United States. President Hoover desired a limited upward revision of tariff rates with general increases on farm products and adjustment of a few industrial rates. A congressional joint committee, however, in compromising the differences between a high Senate tariff bill and a higher House tariff bill, arrived at new high rates by generally adopting the increased rates of the Senate on farm products and those of the House on manufactures. Despite wide protest, the tariff act, called the Hawley-Smoot Tariff Act because of its joint sponsorship by Representative Willis C. Hawley and Senator Reed Smoot, both Republicans, was signed (June, 1930) by President Hoover. The act brought retaliatory tariff acts from foreign countries, U.S. foreign trade suffered a sharp decline, and the depression intensified.

or customs duty

Tax levied upon goods as they cross national boundaries, usually by the government of the importing country. The words tariff, duty, and customs are generally used interchangeably. Usually assessed on imports, tariffs may apply to all foreign goods or only to goods produced outside the borders of a customs union. A tariff may be assessed directly, at the border, or indirectly, by requiring the prior purchase of a license or permit to import specified quantities of the good. Examples of tariffs include transit duties and import or export taxes, which may be levied on goods passing through a customs area en route to another destination. In addition to providing a source of revenue, tariffs can effectively protect local industry by driving up the price of an imported item that competes with domestic products. This practice allows domestic producers either to charge higher prices for their goods or to capitalize on their own lighter taxes by charging lower prices and attracting more customers. Tariffs are often used to protect “infant industries” or to safeguard older industries that are in decline. They are sometimes criticized for imposing hidden costs on domestic consumers and encouraging inefficiency in domestic industries. Tariffs are subject to negotiation and treaties among nations (see General Agreement on Tariffs and Trade; trade agreement; World Trade Organization).
