The mistake many importers make after a major court decision is assuming policy momentum stops. It usually does not. In the weeks after the Supreme Court ended IEEPA tariffs, the administration shifted the trade conversation into other statutes that do not depend on IEEPA at all.
The Immediate Replacement: Section 122
On February 20, 2026, the White House issued a proclamation imposing a temporary 10 percent import surcharge under Section 122 of the Trade Act of 1974. The surcharge took effect on February 24, 2026 and is scheduled to run for 150 days, through July 24, 2026, unless Congress extends it.
For importers, that means the post-IEEPA period still contains a broad-based cost story. It is just being routed through a different legal authority.
Why Section 122 Is Different
Section 122 is temporary by design and comes with statutory limits. The February 20 proclamation also states that the surcharge does not stack on top of tariffs imposed under Section 232 for the same portion of an import.
That creates a more technical planning exercise than the headline might suggest. Teams need to separate:
— Products already touched by Section 232
— Products exposed only to the temporary Section 122 surcharge
— Products that may later be affected by a different authority altogether
The Next Pipeline: Section 301
On March 11, 2026, USTR initiated Section 301 investigations into structural excess capacity and production in manufacturing sectors across a broad list of economies. USTR said public hearings would begin on May 5.
This is not an immediate tariff bill in the way a proclamation is. It is a policy pipeline. But it is a serious one, because Section 301 investigations are how future trade actions become more concrete.
Why Importers Should Care Before Any Final Action
The USTR fact sheet listed sectors that importers should read as an early warning map: aluminum, automobiles, batteries, chemicals, electronics, semiconductors, solar modules, steel, machinery, and others. If a company buys into one of those lanes from one of the investigated economies, it should not wait for the final measure to start scenario planning.
The better discipline is to build a quick exposure grid now:
— Supplier country
— HTS chapter or product family
— Current duty stack
— Section 232 exposure, if any
— Margin sensitivity if another trade action lands
What the Blog Opportunity Is
This is exactly the type of trade content that should sit beside refund education. Importers are not only asking how to recover old duties. They are also asking which authority may create the next layer of landed-cost pressure.
That means topical blog coverage should track both sides of the problem: recovery from invalidated duties and preparation for replacement duties.
