Tariff of 1791 or Excise Whiskey Tax of 1791 was a United States statute establishing a taxation policy to further reduce Colonial America public debt as assumed by the residuals of American Revolution. The Act of Congress imposed duties or tariffs on domestic and imported distilled spirits generating government revenue while fortifying the Federalist Era.

The Tariff of 1792 was the third of Alexander Hamilton's protective tariffs in the United States. Hamilton had persuaded the United States Congress to raise duties slightly in 1790, and he persuaded them to raise rates again in 1792, although still not to his satisfaction. Protectionism was one of the fulfillments of Hamilton's Report on Manufactures.
The Tariff of 1833, enacted on March 2, 1833, was proposed by Henry Clay and John C. Calhoun as a resolution to the Nullification Crisis. Enacted under Andrew Jackson's presidency, it was adopted to gradually reduce the rates following Southerners' objections to the protectionism found in the Tariff of 1832 and the 1828 Tariff of Abominations; the tariffs had prompted South Carolina to threaten secession from the Union. This Act stipulated that import taxes would gradually be cut over the next decade until, by 1842, they matched the levels set in the Tariff of 1816—an average of 20%. The compromise reductions lasted only two months into their final stage before protectionism was reinstated by the Black Tariff of 1842.

The African Growth and Opportunity Act, or AGOA is a piece of legislation that was approved by the U.S. Congress in May 2000. The stated purpose of this legislation is to assist the economies of sub-Saharan Africa and to improve economic relations between the United States and the region. After completing its initial 15-year period of validity, the AGOA legislation was extended on 29 June 2015 by a further 10 years, to 2025.

The Andean Trade Promotion and Drug Eradication Act (ATPDEA) is a trade preference system by which the United States grants duty-free access to a wide range of exports from four Andean countries: Bolivia, Colombia, Ecuador and Peru. It was enacted on October 31, 2002 as a replacement for the similar Andean Trade Preference Act (ATPA). The purpose of this preference system is to foster economic development in the Andean countries to provide alternatives to coca production. Bolivia has installed capacity to industrialize coca production and its derivatives, since coca has no narcotic effects, but the United States does not make any difference between coca and cocaine. Thus, the U.S. government eliminated this "preference".

The Buy American Act passed in 1933 by Congress and signed by President Hoover on his last full day in office, required the United States government to prefer U.S.-made products in its purchases. Other pieces of federal legislation extend similar requirements to third-party purchases that utilize federal funds, such as highway and transit programs.

The Byrd Amendment—named for its author, Senator Harry F. Byrd Jr. of Virginia—was a 1971 amendment to the U.S. Federal Strategic and Critical Materials Stock Piling Act. It prohibited the US government from banning the importation of any strategic material from a non-communist country as long as the importation of the same materials from communist countries was also not prohibited. While it did not single out any particular country, it had the effect–intended by its sponsors–of creating an exception in the United States embargo of Rhodesia to enable the import of chromite ore from that country.

The Chicken Tax is a 25 percent tariff on light trucks imposed in 1964 by the United States under President Lyndon B.

The Clean Diamond Trade Act (CDTA), signed by United States President George W. Bush on 25 April 2003, implemented the Kimberley Process Certification Scheme (KPCS) to regulate the commercial sale of diamonds. On July 29, 2003, Bush signed Executive Order 13312, which described the implementation of the Clean Diamond Trade act. The act requires that all diamonds imported to the United States or exported from the United States have a Kimberley Process Certificate. The act aims to prohibit the importation of diamonds whose mining fuels conflict in the country of origin.

The Cuban Democracy Act (CDA), also known as the Torricelli Act or the Torricelli-Graham Bill, was a bill introduced and sponsored by U.S. Congressman Robert Torricelli and aimed to tighten the U.S. embargo on Cuba. It reimplemented the ban of U.S. subsidiaries in other countries from trading with Cuba, hindered the ability for ships docked within Cuban ports to travel to U.S. ports, and worked to circumvent other aspects of the embargo to provide humanitarian aid to Cuba in an attempt to draw the Cuban people closer to the United States.

The act was signed into law by President Barack Obama on May 11, 2016. It underscored Congress’s desire to align closely with the Uniform Trade Secrets Act, which had been adopted in some form in almost every U.S. state. Technically, the DTSA extended the Economic Espionage Act of 1996, which criminalizes certain trade secret misappropriations.

The Embargo Act of 1807 was a general trade embargo on all foreign nations that was enacted by the United States Congress. As a successor or replacement law for the 1806 Non-importation Act and passed as the Napoleonic Wars continued, it represented an escalation of attempts to coerce Britain to stop any impressment of American sailors and to respect American sovereignty and neutrality but also attempted to pressure France and other nations in the pursuit of general diplomatic and economic leverage.

The Export Administration Act (EAA) of 1979 provided legal authority to the President to control U.S. exports for reasons of national security, foreign policy, and/or short supply. The act was in force from 1979 to 1994, with a lapse in 1984–85. During this lapse, and upon the law's expiration, the authority of export regulations was continued by executive authority.

The Fordney–McCumber Tariff of 1922 was a law that raised American tariffs on many imported goods to protect factories and farms. The US Congress displayed a pro-business attitude in passing the tariff and in promoting foreign trade by providing huge loans to Europe. That, in turn, bought more US goods. However, five years after the passage of the tariff, American trading partners had raised their own tariffs by a significant degree. France raised its tariffs on automobiles from 45% to 100%, Spain raised its tariffs on American goods by 40%, and Germany and Italy raised their tariffs on wheat. According to the American Farm Bureau, farmers lost more than $300 million annually as a result of the tariff.

Macon's Bill Number 2, which became law in the United States on May 14, 1810, was intended to motivate Great Britain and France to stop seizing American ships, cargoes, and crews during the Napoleonic Wars. This was a revision of the original bill by Representative Nathaniel Macon, known as Macon's Bill Number 1. Macon's Bill Number 2 was the fourth in a series of embargo measures, coming after the Non-Importation Act, the Embargo Act, and the Non-Intercourse Act (1809). Macon neither wrote the bill nor approved it.

The Tariff Act of 1890, commonly called the McKinley Tariff, was an act of the United States Congress, framed by then Representative William McKinley, that became law on October 1, 1890. The tariff raised the average duty on imports to almost fifty percent, an act designed to protect domestic industries from foreign competition; protectionism, a tactic supported by Republicans, was fiercely debated by politicians and condemned by Democrats.

The Non-Importation Act, passed by the United States Congress on April 18, 1806, forbade import of certain British goods in an attempt to coerce Britain to suspend its impressment of American sailors and to respect American sovereignty and neutrality. The Act was the first in a series of ineffective attempts of Congress and the administrations of President Thomas Jefferson and James Madison to respond economically, instead of militarily, to these British actions and to other consequences of the Napoleonic Wars. The Act was part of the chain of events leading to the War of 1812.

In the last sixteen days of President Thomas Jefferson's presidency, the Congress replaced the Embargo Act of 1807 with the almost unenforceable Non-Intercourse Act of March 1809. This Act lifted all embargoes on American shipping except for those bound for British or French ports. Its intent was to damage the economies of the United Kingdom and France. Like its predecessor, the Embargo Act, it was mostly ineffective, and contributed to the coming of the War of 1812. In addition, it seriously damaged the economy of the United States. The Non-Intercourse Act was followed by Macon's Bill Number 2. Despite hurting the economy as a whole, the bill did help America begin to industrialize, as no British manufactured goods could be imported, so these goods instead had to be produced domestically.

The Reciprocal Tariff Act provided for the negotiation of tariff agreements between the United States and separate nations, particularly Latin American countries. The Act served as an institutional reform intended to authorize the president to negotiate with foreign nations to reduce tariffs in return for reciprocal reductions in tariffs in the United States up to 50%. It resulted in a reduction of duties. This was the policy of the low tariff Democrats in response to the high tariff Republican program which produce the Hawley Smoot tariff of 1930 that raised rates, and sharply reduced international trade. The Reciprocal Tariff Act was promoted heavily by Secretary of State Cordell Hull.

The Revenue Act of 1913, also known as the Underwood Tariff or the Underwood-Simmons Act, re-established a federal income tax in the United States and substantially lowered tariff rates.

TWEA was amended in 1933 by the Emergency Banking Act to extend the president’s authority also in peace time. It was amended again in 1977 by the International Emergency Economic Powers Act (IEEPA) to restrict the application of TWEA only in times of war, while the IEEPA was intended to be used in peace time.

The Trump tariffs are a series of United States tariffs imposed during the presidency of Donald Trump as part of his "America First" economic policy to reduce the United States trade deficit by shifting American trade policy from multilateral free trade agreements to bilateral trade deals. In January 2018, Trump imposed tariffs on solar panels and washing machines of 30 to 50 percent. In March 2018, he imposed tariffs on steel (25%) and aluminum (10%) from most countries, which, according to Morgan Stanley, covered an estimated 4.1 percent of U.S. imports. In June 2018, this was extended to the European Union, Canada, and Mexico. The Trump administration separately set and escalated tariffs on goods imported from China, leading to a trade war.
