Background
For the third time in less than eighteen months, the Trump administration has rebuilt the legal foundation under its global tariff program, and on July 24, 2026, a sweeping new set of duties on 60 trading partners took effect at 12:01 a.m., replacing a temporary levy that expired by operation of law at the stroke of midnight. The story of how the White House arrived at this point is itself a study in how aggressively the administration has been willing to search for statutory authority to keep tariffs in place after courts have repeatedly narrowed its options.
The chain of events begins in February 2026, when the Supreme Court ruled 6-3 in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act does not authorize a president to impose tariffs, striking down the broad “reciprocal” tariff regime the administration had built during 2025. Within hours of that ruling, the White House pivoted to Section 122 of the Trade Act of 1974, a rarely used provision that allows a president to impose a temporary import surcharge of up to 15 percent for 150 days to address balance-of-payments problems, without requiring congressional approval up front. A 10 percent global duty under Section 122 took effect February 24, 2026.
That stopgap measure faced its own legal turbulence. In May, a divided three-judge panel of the U.S. Court of International Trade ruled in Oregon v. United States and a companion case, Burlap and Barrel, Inc. v. United States, that the Section 122 tariffs were themselves unlawful. A federal appeals court allowed the duties to stay in effect while that ruling was appealed, but Section 122 authority is capped at 150 days and cannot be extended without an act of Congress — and no such legislation was ever introduced. That fixed the expiration date at July 24, 2026, giving the administration a hard deadline to find a more durable legal vehicle if it wanted to preserve a broad tariff wall.
The vehicle it settled on was Section 301 of the same 1974 trade law, the same authority used for the targeted China tariffs of Trump's first term, but this time built around forced labor rather than intellectual property or subsidies. U.S. Trade Representative Jamieson Greer's office opened 60 simultaneous Section 301 investigations in March 2026, examining whether major trading partners had imposed and were enforcing bans on importing goods made with forced labor, a practice nominally required for compliance with international labor norms. USTR published preliminary findings in early June proposing tariffs on all 60 economies, took public comment, held a hearing on July 7, and issued its final determination on July 23 — timed to take effect the moment Section 122 expired.
Key Developments
The new tariff structure covers roughly 99.4 percent of all U.S. imports by value, a scope that makes it, in practical effect, a near-universal replacement for the expiring Section 122 surcharge rather than a narrow, targeted action. USTR sorted the 60 economies into tiers based on their forced-labor enforcement records. Countries determined to have adopted at least some import restrictions on forced-labor goods — a group that includes Argentina, Bangladesh, Canada, Cambodia, Ecuador, El Salvador, Guatemala, Honduras, India, Indonesia, Jordan, Malaysia, Mexico, Pakistan, Sri Lanka, Trinidad and Tobago, and the United Kingdom — face a 10 percent duty. The remaining 38 economies, including China and Vietnam, which USTR found had done nothing to ban forced-labor imports, face a 12.5 percent rate. A handful of major partners, including the European Union, Taiwan, Japan, South Korea, and Switzerland, will see blended rates that vary by product line, generally landing between 10 and 12.5 percent net of existing most-favored-nation duties.
USTR drew a further distinction among six economies — Canada, Ecuador, the European Union, Indonesia, Mexico, and Pakistan — that it said have forced-labor bans on the books but have failed to enforce them effectively, as opposed to the remaining 54 that never adopted a ban at all. Several significant carve-outs blunt the tariffs' reach: oil and gas, goods that cannot reasonably be sourced domestically, pharmaceuticals, aircraft components, fertilizer, and basic food staples are all exempted, and goods that qualify under the U.S.-Mexico-Canada Agreement's rules of origin are excluded entirely, which shields the bulk of continental trade with Canada and Mexico from the new duty despite both countries appearing on the tariff list. Products already covered under separate Section 232 national-security tariff actions are also carved out to avoid stacking.
Perhaps the most consequential feature is a built-in escalation clause. The 10 to 12.5 percent rates apply for a two-year transition period. Any country that has not adopted an effective forced-labor import ban by the end of that window faces a jump to 100 percent tariffs for a further year, then 200 percent tariffs thereafter — a structure that gives the policy the character of an ultimatum as much as a tariff schedule, and one clearly designed to survive future litigation by resting on a different statutory hook than the IEEPA and Section 122 authorities courts have already curtailed.
The timing collided with an already jittery moment in global markets. Asian equities sold off sharply on July 24, with South Korea's KOSPI falling more than 5 percent and triggering a circuit-breaker “sidecar” halt, and Japan's Nikkei dropping over 2 percent. Traders and analysts attributed the slide to a combination of factors rather than the tariffs alone — renewed unease over AI-related spending following a selloff in Alphabet shares, and oil prices above $100 a barrel driven substantially by the ongoing U.S.-Iran conflict and Strait of Hormuz disruptions. Untangling how much of the market move was tariff-driven versus a product of these other, larger shocks is difficult, and outlets differed in how much weight they assigned to each factor.
Reactions
The response from foreign capitals was notably uniform in substance, if not in tone: virtually every affected government rejected the forced-labor rationale as pretextual, while stopping short of announcing retaliation. Brazil's government called the levies “arbitrary.” Australia's government labeled the action “unjustified.” Japan's government described it as “regrettable.” Coverage from CNBC's morning newsletter summarized the mood bluntly under the headline that trading partners were rejecting Trump's tariffs as arbitrary. Notably, the reporting indicates that from Canberra to Brasília, governments signaled a preference for continued negotiation over immediate retaliatory tariffs of their own, a marked contrast to the tit-for-tat tariff escalations that characterized earlier rounds of the 2025-2026 trade conflict.
Inside the United States, reaction split along familiar lines. Trade groups representing import-dependent manufacturers and retailers warned that the duties, even with exemptions, would raise costs across supply chains that had only recently adjusted to the now-expiring Section 122 surcharge, creating a fresh round of pricing and sourcing uncertainty. Administration officials, for their part, framed the forced-labor justification as a matter of enforcing existing U.S. legal obligations — the Tariff Act's long-standing prohibition on importing goods made with forced labor — rather than as a tariff action dressed up in humanitarian language, arguing that trading partners have simply failed to hold up their end of international labor commitments.
The forced-labor framing itself has drawn skepticism from trade lawyers and economists, several of whom noted that many of the 60 named economies, including close allies like the United Kingdom, Japan, and South Korea, have functioning legal frameworks against forced labor and that the enforcement gaps USTR identified appear in some cases to be more technical than substantive. That skepticism is part of why multiple outlets described the move as reconstructing a tariff wall under new legal packaging rather than addressing a freshly discovered trade abuse.
What's Next
Legal challenges are widely expected, though trade attorneys note that Section 301 rests on firmer statutory footing than either IEEPA or Section 122, since Section 301 explicitly contemplates tariff action following a formal investigation and comment process, the kind of administrative record that courts have generally deferred to in the past. Even so, given that this is the third legal vehicle the administration has used to sustain a global tariff program in a year and a half, further litigation from importers and possibly from foreign governments before the World Trade Organization appears likely in the coming weeks.
The two-year transition clock is now the central variable to watch. Countries eager to avoid the escalation to triple-digit tariff rates will face pressure to demonstrate concrete forced-labor enforcement measures well before the deadline, and expect bilateral negotiations — particularly with the European Union, United Kingdom, and India — to focus on securing rate reductions or exemptions in exchange for tightened import-screening regimes. Separately, the European Union's reaction to these tariffs is now entangled with a parallel and escalating dispute over Brussels' own regulatory fine against Google under the Digital Markets Act, announced the same week, which the U.S. Trade Representative has said complicates prospects for a broader EU-U.S. trade settlement.
Congress remains a wildcard. No legislation to extend or replace Section 122 has been introduced, and there is no indication that lawmakers plan to take up forced-labor trade legislation that would supersede the executive action. Absent congressional intervention, the practical effect is that the administration has, for now, succeeded in re-establishing a near-universal tariff floor across almost all U.S. trade relationships using an authority that has not yet been tested in court, and markets, importers, and foreign governments will spend the coming weeks assessing how durable that floor proves to be.
