IEEPA Tariff Refunds: What $175 Billion Means
The Supreme Court struck down IEEPA tariffs 6-3. $175 billion in refunds are in play, but replacement tariffs may erase the gains.
On February 20, the Supreme Court ruled 6-3 that the International Emergency Economic Powers Act does not authorize tariffs. The decision invalidated duties that had generated an estimated $175 billion to $179 billion in revenue since their imposition, according to the Penn Wharton Budget Model. That sum exceeds the combined FY2025 budgets of the Department of Transportation and the Department of Justice. And now, importers want it back.
The ruling itself is straightforward. IEEPA grants the president broad emergency powers over financial transactions, but the Court held that those powers do not extend to imposing duties on imported goods. That authority belongs to Congress. The practical consequence is equally straightforward: every dollar collected under IEEPA tariff orders is potentially refundable.
But “potentially” is doing a lot of work in that sentence. The administration moved within days to replace the voided tariffs with new ones drawn from different statutes. Whether the refunds will matter, or whether they will be swallowed by replacement duties before importers ever see a check, is the real question.
How Do Importers Get Their Money Back?
U.S. Customs and Border Protection is standing up a refund portal expected to go operational by mid-April. The initial phase will cover roughly 63% of the 53 million unliquidated import entries subject to IEEPA duties. Importers whose entries have already been liquidated will need to file formal protests under 19 U.S.C. Section 1514, and they have 180 days after liquidation to do so.
The logistics are significant. CBP processes millions of entries per year, and the agency has never attempted a retroactive refund of this scale. The 180-day clock creates urgency for importers who may not realize their entries have already been liquidated. Companies with large import volumes, particularly in retail, manufacturing, and agriculture, could recover substantial sums. But the bureaucratic pipeline will take months, possibly over a year, to clear.
What Replaced the IEEPA Tariffs?
The administration did not leave a vacuum. Within a week of the ruling, the White House issued an Executive Order terminating IEEPA duties and replacing them with a temporary 10% across-the-board duty under Section 122 of the Trade Act of 1974. That provision allows the president to impose duties of up to 15% for 150 days in response to balance-of-payments emergencies.
On top of that, new Section 232 tariffs took effect April 6. The structure is aggressive:
| Category | Tariff Rate | Authority | Effective Date |
|---|---|---|---|
| Steel articles | 50% flat | Section 232 | April 6, 2026 |
| Aluminum articles | 50% flat | Section 232 | April 6, 2026 |
| Copper articles | 50% flat | Section 232 | April 6, 2026 |
| Steel/aluminum/copper derivatives | 25% | Section 232 | April 6, 2026 |
| All other imports | 10% | Section 122 | Immediate |
Treasury Secretary Scott Bessent told reporters that the combination of Section 122, Section 232, and existing Section 301 duties “will result in virtually unchanged tariff revenue.” In other words, the administration intends to collect the same amount of money, just under different legal authorities.
Does the Refund Actually Help the Economy?
In theory, $175 billion flowing back to importers could provide meaningful stimulus. Many of those importers passed tariff costs through to consumers. The Tax Foundation estimates that tariffs added roughly $1,500 per household in annual costs during 2026. A refund wave could ease some of that burden, at least temporarily.
But the timing matters. If $175 billion floods back into the economy over a compressed period, it could add inflationary pressure at exactly the wrong moment. The Fed is already navigating a narrow path between cooling inflation and slowing growth. A sudden cash injection, even one that technically represents money that should never have been collected, could complicate rate decisions through the second half of the year.
And if the replacement tariffs are generating “virtually unchanged” revenue, then importers are paying new duties at roughly the same rate they are recovering old ones. The net effect on consumer prices could be close to zero. For a deeper look at how tariff policy has shaped 2026 markets, see our analysis of Liberation Day tariffs one year later.
Is Section 122 on Firmer Legal Ground?
This is where the story gets uncomfortable. Section 122 has never been used at this scale. The statute was designed as a short-term emergency tool, not a replacement architecture for a multi-hundred-billion-dollar tariff regime. Legal scholars are already divided on whether the administration’s invocation of balance-of-payments authority will survive judicial review.
The 150-day time limit creates its own problem. If Section 122 duties expire without a Congressional replacement, the administration would need yet another statutory basis to maintain tariff revenue. The legal ground may be shifting rather than stabilizing.
Multiple trade associations have signaled they intend to challenge the Section 122 tariffs on the same delegation grounds that brought down the IEEPA duties. If those challenges succeed, the cycle could repeat: collection, litigation, invalidation, refund.
What Is Happening Outside the United States?
While Washington cycles through legal authorities, the rest of the world is adapting. Marketplace reports that multiple countries are actively negotiating bilateral trade agreements that exclude the United States. The EU, Japan, South Korea, and several ASEAN nations have accelerated tariff reductions among themselves, building supply chains that route around American trade barriers.
The long-term risk is structural. Tariffs are designed to create leverage at the negotiating table. If other nations simply build around U.S. trade policy rather than negotiate through it, the leverage diminishes regardless of which statute the duties are collected under. American exporters may face a world where barriers are falling everywhere except for them.
What Comes Next?
The next 90 days will determine whether the IEEPA refund is a real economic event or a legal footnote offset by replacement duties. Three variables to watch:
CBP portal operations. If the mid-April launch goes smoothly and refunds begin processing, small and mid-size importers could see meaningful cash flow relief by summer. Delays or backlogs would push the timeline into Q4 or beyond.
Section 122 litigation. Any successful challenge would invalidate the replacement tariffs and trigger a second round of refund claims. The administration would face the same constitutional question under a different statute.
Congressional action. If Congress legislates a permanent tariff framework, it could moot the delegation challenges entirely. But trade legislation moves slowly, and the current session has shown little appetite for broad tariff reform.
The Supreme Court’s IEEPA ruling resolved one constitutional question cleanly. The economic consequences, though, remain unsettled. $175 billion in refunds sounds like a windfall. Whether it functions as one depends entirely on what replaces the revenue, and whether that replacement survives its own day in court.
