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

The timeline here is unusually compressed for trade policy. The Supreme Court's February ruling against the previous tariff regime left the administration needing a legally durable replacement, not just a temporary one. Section 122 filled the immediate gap because it could be invoked without a lengthy investigation, but Congress built a 150-day limit into the law specifically to stop a president from running a long-term tariff programme on emergency authority alone. That clock runs out around July 24, which is why the Section 301 process, comment period closing July 6 and hearing on July 7, needed to move so quickly.

Section 301 works differently from both of the authorities it is replacing. Rather than citing a national emergency or a balance-of-payments problem, it requires the US Trade Representative to formally investigate and find that a trading partner is engaged in an "unfair" trade practice. In this case, USTR built its investigation around forced labour enforcement, finding that 59 countries and the European Union have not adequately banned or enforced prohibitions on importing goods made with forced labour. That finding, whatever one thinks of its substance, gives the administration a statutory basis that does not carry Section 122's rate cap or Section 122's 150-day clock.

The proposed rates split trading partners into two tiers: 10% for a smaller group of 14 economies, and 12.5% for the remaining 46, a group that includes India. For India specifically, that would mean a rate higher than the 10% it currently pays under Section 122, reversing part of the relief exporters had gotten since the IEEPA tariffs, which had reached 18% for India, were struck down in February.

For businesses, the compressed timeline leaves very little room to plan. Companies that adjusted pricing and sourcing decisions around the 10% Section 122 rate now have to model a scenario where their effective tariff rises again within weeks, without knowing for certain whether the July 7 hearing will change the proposed 10% or 12.5% figures before they take effect. Trade lawyers advising importers have generally counselled clients to prepare for the proposed rates to go into effect close to as published, since Section 301 investigations of this kind have historically resulted in tariffs close to the rates originally proposed.

There's also a legal-durability argument underlying the entire sequence. IEEPA tariffs, with no rate cap and no time limit, proved constitutionally vulnerable precisely because they looked like an unbounded delegation of Congress's taxing power to the presidency. Section 122 tariffs are safer but only ever temporary. Section 301, because it flows from a specific investigative finding under a decades-old trade statute that Congress itself passed and has repeatedly reauthorised, has survived legal challenges in the past, most notably the tariffs imposed on Chinese goods in 2018 and 2019 under the same authority, which were narrowed somewhat in litigation but ultimately upheld.

That history is precisely why the administration is leaning on Section 301 now rather than trying to extend Section 122 through Congress or defend IEEPA further at the Supreme Court. A tool that has already survived a round of litigation is a safer long-term foundation for tariff policy than one the Supreme Court has just struck down or one that is legally temporary by design.

None of this resolves the underlying trade dispute with any of the 59 countries involved, since a forced-labour finding is, in a formal sense, distinct from the balance-of-payments or national-security rationale used previously. Trading partners named in the investigation, India among them, are left negotiating on two tracks simultaneously: disputing the specific forced-labour findings against them, while also absorbing whatever tariff rate emerges from a process that is more about giving the administration a durable legal tool than about the underlying labour-practice allegations themselves.
