The Supreme Court Killed IEEPA Tariffs — Trump's Section 122 Surcharge Is the Replacement
The Court ruled IEEPA doesn't authorize tariffs, striking down roughly 70% of the US tariff architecture overnight. The replacement — a Section 122 surcharge — comes with a hard 150-day clock.
On February 20, 2026, the Supreme Court dismantled the legal foundation underneath most of the United States' tariff regime in a single ruling — and the scramble to replace that foundation is still an active, unresolved story heading into Q4 2026.
The ruling that changed everything
In Learning Resources, Inc. v. Trump, the Court ruled 6-3 that the International Emergency Economic Powers Act (IEEPA) does not authorize tariffs at all — that power, Chief Justice Roberts wrote (invoking the major questions doctrine), belongs to Congress, not the executive branch acting under emergency economic powers. The scale of the impact is hard to overstate: IEEPA tariffs had made up roughly 70% of the entire US tariff architecture at the time of the ruling.
The replacement: Section 122
The administration didn't wait. It proclaimed a new 15% global tariff under Section 122 of the Trade Act of 1974 — a genuinely different legal authority with a built-in constraint the IEEPA tariffs never had: Section 122 caps any surcharge at 15% and 150 days, unless Congress affirmatively extends it.
The part worth tracking right now
That 150-day clock is the detail that makes this a live story rather than settled history. Depending on the exact proclamation date, the Section 122 surcharge's sunset window falls somewhere in the current quarter — meaning the tariff authority actually taxing a huge share of US imports right now has a built-in expiration that Congress would need to act to extend.
The rest of the toolkit is filling the gap
While Section 122 covers the broad global surcharge, Sections 301 and 232 tariff activity — narrower, sector- and country-specific authorities that survived the IEEPA ruling untouched — has grown substantially since February, as the administration uses every remaining legal tool available to maintain tariff coverage the IEEPA mechanism used to provide.
Why this matters for Indian exporters specifically
For any business with US-bound trade exposure — and that includes a large share of Indian exporters — the practical problem isn't a single tariff rate, it's that the legal authority actually taxing your goods keeps changing. A shipment taxed under IEEPA in January might be taxed under Section 122 by spring, and under Section 301 or 232 by year-end, each with different rate structures, exemptions, and renewal mechanics. Trade counsel advising exporters should be tracking which specific authority currently applies to each product category, not just the headline tariff percentage — because the headline percentage is the one thing likely to keep changing as this plays out through Congress and the courts.
