Supreme Court Strikes Down Trump's Tariffs: What the IEEPA Ruling Means for Importers
In a landmark 6–3 decision, the Supreme Court ruled that IEEPA does not authorize the President to impose tariffs, striking down the Liberation Day and fentanyl tariffs. Over $175 billion in refunds may be at stake — here's what importers need to know and do right now.
⚡ Updated: February 21, 2026 — One day after the ruling, Trump announced a new 15% global tariff under Section 122 of the Trade Act of 1974, effective immediately. See updated tariff table and analysis below.
In a landmark 6–3 decision handed down this morning, the U.S. Supreme Court ruled that President Trump exceeded his authority when he used the International Emergency Economic Powers Act to impose sweeping tariffs on imports. The case, Learning Resources, Inc. v. Trump, invalidates every tariff imposed under IEEPA — including the "Liberation Day" tariffs and the fentanyl-related duties on China, Canada, and Mexico.
Chief Justice John Roberts, writing for the majority, did not mince words: "Based on two words separated by 16 others in IEEPA — 'regulate' and 'importation' — the President asserts the independent power to impose tariffs on imports from any country, of any product, at any rate, for any amount of time. Those words cannot bear such weight."
The ruling doesn't end all tariffs. Section 232 duties on steel and aluminum remain in place. But for the more than 200,000 small business importers who have been paying IEEPA duties since early 2025, this decision opens the door to billions in potential refunds — and raises urgent questions about what comes next.
What Did the Court Actually Decide?
The Supreme Court held that IEEPA does not grant the President authority to impose tariffs. Period.
Roberts was joined by Justices Sotomayor, Kagan, Gorsuch, Barrett, and Jackson. In a section joined by Gorsuch and Barrett, Roberts invoked the major questions doctrine — the principle that Congress must speak clearly when delegating authority over issues of vast economic significance. Imposing tariffs worth hundreds of billions of dollars, the Court said, is exactly that kind of issue.
"The fact that no President has ever found such power in IEEPA is strong evidence that it does not exist," Roberts wrote.
The three dissenters — Justices Thomas, Alito, and Kavanaugh — argued that IEEPA's broad language does encompass tariff authority. Kavanaugh warned in his dissent that the ruling could create a "mess" when it comes to refunding what the government has already collected.
Which Tariffs Were Struck Down?
Estimate your refund: TariffCenter's free IEEPA Refund Estimator calculates how much you could recover from CBP based on your total IEEPA duties paid, the percentage attributable to struck-down tariffs, and whether your entries are still unliquidated or in protest. Takes under a minute.
The ruling eliminates all tariffs imposed under IEEPA, not just the ones that were directly argued before the Court. The defect the Court identified — lack of statutory authority — applies to every IEEPA-based tariff regardless of country, rate, or duration.
Here's what's gone and what remains:
| Tariff Program | Legal Authority | Status After Ruling |
|---|---|---|
| "Liberation Day" tariffs (57 countries) | IEEPA | Struck down |
| Fentanyl tariffs (China, Canada, Mexico) | IEEPA | Struck down |
| Section 232 (steel and aluminum) | Trade Expansion Act | Unaffected |
| Section 301 (China) | Trade Act of 1974 | Unaffected |
| MFN base duties | Tariff Act of 1930 | Unaffected |
| Antidumping/CVD duties | Title VII | Unaffected |
The Tax Foundation estimates that IEEPA tariffs have raised more than $160 billion since they took effect. According to the Cato Institute, over 60 percent of total tariff revenue last year came from IEEPA duties. With those gone, economists estimate the average U.S. tariff rate will drop from roughly 16% to about 7%.
The Refund Question: $175 Billion at Stake
The immediate question for every importer: will I get my money back?
The answer is: probably, but it won't be quick or simple.
The Court remanded the case to the U.S. Court of International Trade (CIT) to work out refund procedures. More than 1,000 lawsuits have already been filed by importers seeking refunds, and a flood of new cases is expected. Economists told Reuters on Friday that over $175 billion in tariff collections are at risk of being refunded.
The U.S. Chamber of Commerce called for "swift refunds of the impermissible tariffs," adding that getting money back "will be meaningful for the more than 200,000 small business importers in this country."
But there are complications. Justice Kavanaugh flagged one in his dissent: some importers passed tariff costs on to consumers. Whether they can still recover is a question the lower courts will need to sort out. And smaller businesses may face a tougher road — lawyers have noted that some smaller importers might abandon potential refunds rather than pay thousands in legal and court fees.
What You Need to Do Right Now
If you paid IEEPA tariffs at any point since they took effect, here are the steps to protect your refund eligibility:
1. Inventory your IEEPA duty exposure. Pull records of every import entry where you paid reciprocal tariffs or fentanyl tariffs. Separate these from Section 301, Section 232, and MFN base duties — those aren't affected.
2. Check your liquidation status. Entries that haven't been liquidated yet are in the strongest position. CBP should now liquidate these without the IEEPA duties. For entries that have been liquidated, you'll need to file a protest.
3. File protests on liquidated entries. You have 180 days from liquidation to file a protest using CBP Form 19 through the Automated Commercial Environment (ACE). Given today's ruling, customs attorneys are recommending filing protests immediately to preserve your rights.
4. Consider joining a CIT case. Importers can also file directly with the Court of International Trade under Section 1581(i). You have two years from the date of entry to bring a claim. Many trade attorneys recommend a "belt-and-suspenders" approach — file both administrative protests and CIT complaints.
5. Update your banking information with CBP. When refunds start flowing, you'll want to make sure CBP has your current electronic banking details to avoid delays.
6. Consult a customs broker or trade attorney. For refund amounts above $10,000, professional guidance is worth the investment. The process will be complex and importers who act early will likely be in a better position.
How Long Will Refunds Take?
Nobody knows for certain. The CIT has overseen large-scale refund processes before — after the Supreme Court struck down part of the harbor maintenance tax in 1998, the CIT managed refunds involving more than 100,000 claimants. But the IEEPA refund will be significantly larger in both dollar terms and number of affected importers.
International trade lawyer Joyce Adetutu of Vinson & Elkins told reporters that issuing a broad-scale refund with the "push of a button" is unlikely. Instead, those who have preserved their claims through protests or CIT filings will be able to seek refunds. Those who don't act may forfeit their right to recovery.
Kuehne + Nagel's Greg Tompsett was more blunt: "We believe it may take months, if not years, to be decided by the CIT."
What This Means for Tariff Policy Going Forward
The ruling is a check on executive power, but it doesn't end tariffs. The administration retains other legal tools:
- Section 301 of the Trade Act of 1974 allows tariffs against countries engaged in unfair trade practices, though it requires investigation and findings by the U.S. Trade Representative.
- Section 232 of the Trade Expansion Act of 1962 allows tariffs for national security reasons, subject to Commerce Department review.
- Congressional action: The President could ask Congress to pass new tariff legislation, though that would require bipartisan support in a divided Congress.
The administration moved within hours. On February 20, Trump announced a new 10% global tariff; by February 21 he raised it to 15% — the maximum rate permitted under Section 122. Trump characterized the Court’s ruling as “ridiculously written and anti-American” and vowed to pursue “new and legally permissible” permanent tariffs in the months ahead.
Morgan Stanley analysts noted that while Section 122 provides a bridge, its 150-day time limit means the tariff landscape could shift again before summer.
A Quick Example: What Changes for Your Business
Before the ruling: A small business importing $500,000 of furniture from Vietnam was paying:
| Duty Layer | Rate | Amount |
|---|---|---|
| MFN base rate | 0% | $0 |
| IEEPA reciprocal tariff | 46% | $230,000 |
| Total duties | $230,000 |
After the ruling: That $230,000 IEEPA tariff is gone. The business now pays only the MFN base rate — $0 in duties on the same shipment. And the $230,000 previously paid? That's now a potential refund claim.
For importers paying multiple layers of tariffs, the math is more nuanced. A business importing electronics from China, for example, still owes Section 301 tariffs even after the IEEPA duties are struck down.
Trump’s Response: New 15% Global Tariff Under Section 122 {#trumps-response}
Updated: February 21, 2026
The Trump administration replaced the struck-down IEEPA tariffs within hours by invoking Section 122 of the Trade Act of 1974 — a statute that explicitly authorizes a presidential import surcharge, but with hard constraints that IEEPA lacked:
- 150-day limit: Section 122 tariffs expire automatically without a Congressional vote to extend them
- 15% rate ceiling: The statutory maximum under Section 122 — exactly where Trump set it
- Exemptions apply: Goods from Canada and Mexico covered under USMCA are largely exempt; certain agricultural products (beef, tomatoes, oranges) are excluded
Current tariff landscape as of February 21, 2026:
| Tariff Program | Authority | Rate | Status |
|---|---|---|---|
| IEEPA “Liberation Day” tariffs | IEEPA | 10–50% | ❌ Struck down |
| IEEPA fentanyl tariffs (China/Canada/Mexico) | IEEPA | 10–25% | ❌ Struck down |
| Section 122 global surcharge | Trade Act of 1974 | 15% | ✅ In effect |
| Section 232 (steel and aluminum) | Trade Expansion Act | 25% / 10% | ✅ Unchanged |
| Section 301 (China) | Trade Act of 1974 | 7.5–25% | ✅ Unchanged |
Updated example — what Vietnam furniture imports look like now:
| Before ruling (IEEPA) | After ruling (Section 122 now) | |
|---|---|---|
| Tariff rate on $500K shipment | 46% = $230,000 | 15% = $75,000 |
| Net duty savings vs. IEEPA | — | $155,000 |
Meaningful relief — but not zero, and the 150-day clock is running. Trump has signaled he will pursue expanded Section 301 investigations and potentially new Congressional tariff legislation to make duties permanent before Section 122 expires.
