# Trade Act of 1974 The **Trade Act of 1974** (signed January 3, 1975) is the statute whose delegated tariff authorities became the primary legal engine of both Trump administration trade wars — and the vault tracks it because it is the clearest example of how a 1970s-era congressional delegation of authority, designed for a world of bilateral trade disputes and balance-of-payments crises, was repurposed fifty years later to impose universal tariffs on a scale Congress never anticipated. The Act is the statutory backbone of the tariff war: when the Supreme Court's February 2026 ruling curtailed the use of the [[International Emergency Economic Powers Act]] for tariffs, the Trade Act of 1974 was the fallback, and its authorities proved sufficient to sustain the core of the administration's trade agenda. ## The statutory architecture The Trade Act of 1974 contains multiple distinct tariff authorities, each with its own trigger, scope, and procedural requirements. The four most significant are Sections 122, 201, 301, and 421. ### Section 122: balance-of-payments surcharge Section 122 empowers the president to impose a temporary import surcharge of up to 15 percent — or, if a surcharge is insufficient, import quotas — to address "large and serious" United States balance-of-payments deficits. The surcharge may remain in place for 150 days without congressional action; Congress must act to extend it beyond that window. Section 122 was the vehicle for the universal 10 percent tariff of February–July 2026, imposed after the Supreme Court's IEEPA ruling forced the administration to find alternative statutory authority. The administration argued that the persistent U.S. trade deficit constituted a "large and serious" balance-of-payments problem within the meaning of the statute. Critics — including Yale Journal on Regulation scholars — argued that Section 122 was designed for currency crises, not trade deficits, and that the administration's reading stretched the statute well beyond its original purpose. The [[Court of International Trade]] held the Section 122 surcharge unlawful on May 7, 2026 (*Oregon v. United States*), but limited relief to the plaintiffs, and the Federal Circuit stayed even that; the surcharge ran until the 150-day window expired on July 24, 2026, at which point the administration pivoted to Section 301 authority for continuation. ### Section 201: global safeguard Section 201 is the "escape clause" — the global safeguard that allows the president to impose tariffs or quotas when the International Trade Commission determines that an article is being imported in such increased quantities as to be a "substantial cause of serious injury, or the threat thereof" to a domestic industry producing a like or directly competitive article. The ITC investigation is a prerequisite; the president may then accept, modify, or reject the ITC's remedy recommendation. Section 201 was used in the first Trump administration for the 2018 tariffs on solar panels and washing machines. The safeguard is time-limited (typically four years with one possible extension) and applies globally — it is not targeted at a specific country. The procedural requirements (ITC investigation, injury determination, remedy recommendation) make Section 201 slower and harder to invoke than Sections 122 or 301, which is why it has been used sparingly compared to the other authorities. ### Section 301: unfair trade practices Section 301 is the most consequential provision for the vault's tariff cluster. It authorizes the president — acting through the U.S. Trade Representative — to impose tariffs or other trade restrictions in response to foreign trade practices that are "unjustifiable," "unreasonable," or "discriminatory" and that burden or restrict U.S. commerce. The USTR must conduct an investigation, but the breadth of the statutory language gives the president enormous discretion in determining what constitutes an unfair practice and what remedy is appropriate. Section 301 was the authority for the first Trump administration's China tariffs of 2018–2019, which began as a response to a USTR investigation into Chinese intellectual property theft, forced technology transfer, and state-subsidized industrial policy. Those tariffs — covering hundreds of billions of dollars in Chinese imports — survived legal challenge and were largely maintained by the Biden administration. In the second Trump administration, Section 301 was the vehicle for the [[Section 301 Forced Labor Tariffs]] imposed July 24, 2026, targeting goods produced with forced labor — a category that extended the "unfair trade practices" concept beyond traditional trade violations into human-rights territory. [[Jamieson Greer]], the U.S. Trade Representative in the second Trump administration, has been the principal architect of the expanded Section 301 strategy. ### Section 421: China safeguard (expired) Section 421 was added to the Trade Act by the U.S.-China Relations Act of 2000, which established permanent normal trade relations with China and paved the way for China's accession to the [[World Trade Organization]]. The provision created a special safeguard mechanism for Chinese imports, with a lower injury threshold ("market disruption" rather than "serious injury") than the global Section 201 safeguard. Section 421 was designed to last twelve years after China's WTO accession — it expired in 2013. During its active period, the Obama administration invoked it once, for Chinese tire imports in 2009. The provision's expiration is one reason the second Trump administration relied on Sections 301 and 122 rather than a China-specific safeguard. ## Trade Adjustment Assistance The Trade Act also created Trade Adjustment Assistance (TAA), the federal program that provides retraining, income support, and relocation assistance to workers displaced by import competition. TAA was the political bargain that made trade liberalization possible: Congress agreed to reduce tariffs, and in exchange, the workers harmed by liberalization would receive transitional support. The program has been reauthorized and modified multiple times but has consistently been underfunded relative to the scale of trade-related job displacement — a fact that feeds the populist critique of free trade. ## Fast-track negotiating authority The Act established "fast-track" trade promotion authority (TPA), under which Congress agrees to vote on trade agreements negotiated by the president on an up-or-down basis, without amendment. Fast-track authority has lapsed and been renewed multiple times; it was most recently active from 2015 to 2021. The mechanism was designed to make trade agreements negotiable (foreign governments will not make concessions if Congress can amend the deal afterward) but has been criticized for reducing congressional oversight of trade policy to a binary choice. ## See also [[Liberation Day Tariffs]] · [[Section 301 Forced Labor Tariffs]] · [[Court of International Trade]] · [[Jamieson Greer]] · [[International Emergency Economic Powers Act]] · [[World Trade Organization]] · [[China]] · [[Donald Trump]]
