The Supreme Court Just Struck Down IEEPA Tariffs — What Amazon Sellers Need to Know — Astra Blog
What Just Happened , And What Didn't
The Supreme Court ruled in Learning Resources, Inc. v. Trump that the International Emergency Economic Powers Act (IEEPA) does not authorize the president to impose tariffs. Six justices agreed, including two Trump appointees. Chief Justice Roberts wrote that the word "regulate" in the statute cannot bear the weight of a sweeping, open-ended tariff regime.
Within hours of the ruling, Trump signed a new proclamation imposing a 10% global tariff under Section 122 of the Trade Act of 1974, a different law. The next day, he raised it to 15%, the statutory maximum. The effective U.S. tariff rate before the ruling was around 13.7%. After Section 122, estimates put it around 8%, still nearly triple the ~3% rate pre-Trump.
The one-sentence version for sellers:
The legal mechanism changed. The tariff burden didn't disappear. And uncertainty, the most damaging thing of all for inventory planning, is still very much in play.
The Tariff Landscape Right Now
| Tariff Type | Status | What It Means |
|---|---|---|
| IEEPA Reciprocal Tariffs ("Liberation Day") | Struck Down | Invalidated. No longer collected. No refund process announced yet. |
| IEEPA Fentanyl Tariffs (China/Canada/Mexico) | Struck Down | Same ruling. Gone, but refunds in limbo at Court of International Trade. |
| Section 122 Global Tariff (15%) | In Effect | Trump's immediate replacement. Expires 150 days unless Congress extends. |
| Section 232 (Steel, Aluminum) | In Effect | Not touched by the ruling. Still in place. Further expansion signaled. |
| Section 301 (China-specific) | In Effect | Not touched. China tariffs remain some of the highest in the stack. |
| IEEPA Tariff Refunds | Unresolved | Returns to Court of International Trade, could take months or years. |
What About Refunds?
The Supreme Court's ruling opened the door to refunds for IEEPA tariffs paid since 2025, estimated at $160–$179 billion, but it did not order them. The Court left the refund question for lower courts. Treasury Secretary Bessent has already signaled the administration has little interest in writing big checks back.
If you paid IEEPA tariffs on imports over the past year, talk to a customs broker or trade attorney about preserving your claim. But don't build your Q2 inventory plan around a refund arriving anytime soon.
