Washington's Next Tariff Move: Section 301 Hearings Land Just Before the Clock Runs Out

Section 301 of the Trade Act of 1974 authorises the US Trade Representative to investigate and respond to a foreign country's acts, policies, or practices that are unjustifiable, unreasonable, or discriminatory and that burden or restrict US commerce. Unlike IEEPA, which is triggered by a presidential declaration of national emergency, or Section 122, which requires a finding of a fundamental balance-of-payments problem, Section 301 requires USTR to conduct a formal investigation, publish findings, and propose a specific remedy, a process that took roughly three months in this case, from the investigations' initiation in March to USTR's published findings and proposed tariffs on June 2.

The forced-labour framing is a deliberate legal choice. USTR's investigations targeted the acts, policies, and practices of the 59 named economies and the EU related to their failure to prohibit or effectively enforce a prohibition on importing goods made with forced labour, a legal theory distinct from the balance-of-payments language used for Section 122 or the national-security and emergency-powers language used for IEEPA and various Section 232 actions in prior years. Framing the investigation around labour standards rather than a generic trade imbalance gives USTR a narrower, more defensible legal target for each individual finding, even though the practical effect (a tariff applied broadly across dozens of countries at once) resembles the earlier IEEPA and Section 122 measures.

The two-tier rate structure, 10% for 14 economies and 12.5% for the remaining 46 including India, appears to correspond to USTR's assessment of the severity or persistence of forced-labour enforcement gaps in each jurisdiction, though the agency's public findings do not fully spell out a numeric methodology for the tier assignment. India's placement in the higher tier means its effective July tariff, if the proposal is finalised without modification, would rise from the current 10% Section 122 rate to 12.5%, a smaller swing than the earlier move from 18% (under IEEPA) to 10% (under Section 122), but a reversal of the recent trend nonetheless.

There is meaningful precedent for Section 301 tariffs surviving legal challenge in a way that IEEPA tariffs did not. During 2018 and 2019, the US imposed Section 301 tariffs on hundreds of billions of dollars of Chinese goods following an investigation into intellectual-property practices. Those tariffs were challenged in the Court of International Trade; while certain aspects of the list-setting process were sent back for further review, the core authority to impose tariffs under Section 301 following a completed investigation was not invalidated. That track record is central to why Section 301 is viewed as a more legally durable foundation than either IEEPA or Section 122 for a tariff regime intended to last beyond a single news cycle.

Procedurally, the public comment period that closed July 6 allowed affected countries, industry groups, and importers to submit objections to both the underlying forced-labour findings and the proposed tariff rates. The July 7 hearing gives interested parties a chance to testify directly to USTR staff and, in some administrations' practice, to political leadership. Historically, comment periods of this kind have led to targeted adjustments, exclusions for specific products, or minor rate changes, rather than wholesale reversals of the proposed structure, which is consistent with trade lawyers' general advice to clients to plan around the proposed rates rather than assume a favourable revision.

The compressed sequencing (comment period closing July 6, hearing July 7, and Section 122 expiring around July 24) leaves USTR roughly two and a half weeks to finalise findings, respond to comments, and issue a final tariff proclamation. That is an unusually tight window for a trade action of this scope, and it reflects the underlying legal pressure: unlike Section 122, which the administration could impose unilaterally within hours of the Supreme Court's ruling, Section 301 requires the investigation-and-comment process to have at least nominally run its course before tariffs can take effect, even on an expedited timeline.

For India, the sequence illustrates how much of its US tariff exposure is currently determined by domestic US legal mechanics rather than by anything specific to the India-US trade relationship. The rate India faces has moved from an IEEPA-era country-specific tariff, to a flat 10% under Section 122, and would move again to 12.5% under the proposed Section 301 action, three different numbers inside of five months, each set by a different US legal authority responding to a different court ruling or investigative finding rather than by a negotiated bilateral agreement. The interim US-India trade understanding reached in late 2025, which assumed the IEEPA framework would remain the operative one, has not been updated to reflect any of these subsequent shifts.

Two Federal Circuit appeals remain pending in the background of this entire sequence: one over the scope of IEEPA tariff refunds, and one over whether Section 122 was validly invoked at all. Neither is likely to be resolved before the Section 301 rates take effect, which means the tariff structure that stabilises by late July will rest on Section 301 even as separate litigation over the two authorities it replaced continues to work through the courts.
