In February the Supreme Court held that the President cannot impose open-ended tariffs under emergency economic powers. That created one of the largest refund obligations in the history of US customs administration — and, six months on, a process that is still working out who gets paid, in what order, and whether an appeal can undo any of it.

Short answer: what the February ruling triggered
Short answer: On February 20, 2026, the Supreme Court ruled 6-3 that the International Emergency Economic Powers Act does not authorise the President to impose tariffs of indefinite scope. Estimates put the resulting refund exposure at up to roughly $175 billion. The ruling itself did not order refunds — it held the collection unlawful, which opened the door to claims. A Court of International Trade order on March 4, 2026 directed Customs and Border Protection to process refunds through normal administrative channels rather than requiring each importer to litigate.

| What was struck down | Tariffs imposed under IEEPA |
| Estimated refund exposure | Up to ~$175 billion |
| Enabling order | US Court of International Trade, March 4, 2026 |
| Claim mechanism | CAPE Declarations submitted through the CAPE portal |

What CAPE is and what it replaces
CAPE is the claim process CBP stood up to handle IEEPA refunds administratively. An importer of record — or a licensed customs broker acting for one — submits a declaration identifying the affected entries, and CBP processes the refund without the importer having to file suit.
The alternative would have been the ordinary route: a protest on each liquidated entry, or a case before the Court of International Trade. For an exposure spanning hundreds of thousands of importers and tens of millions of individual entries, that would have taken years and generated enormous legal cost on both sides. The administrative channel exists because the conventional one could not absorb the volume.
Who is first in line
Not all entries sit in the same position, and the difference determines both timing and certainty.
- Entries already protested. Importers who filed protective claims before the ruling preserved their rights explicitly and sit in the strongest position.
- Unliquidated entries. Still open at CBP, so the duty amount can be adjusted directly rather than refunded after the fact. Administratively the simplest category.
- Liquidated entries within the protest window. Liquidation generally becomes final 180 days after it occurs unless protested, so this category is time-sensitive.
- Liquidated entries past the window. The hardest category, and where most of the genuine legal uncertainty sits.
The practical consequence is that importers who did nothing while the litigation was pending may recover less, later, or not at all — while those who filed protective protests preserved the strongest claim. That asymmetry is a recurring feature of customs litigation and it rewards process discipline over legal insight.
The appeal and timing risk
Neither the Supreme Court decision nor the executive order revoking the tariffs resolved the refund question directly, which left it to renewed proceedings at the Court of International Trade. Continued procedural wrangling can extend payment timelines well beyond initial expectations, and reporting through mid-2026 has consistently described the refund position as unsettled rather than resolved.
For anyone modelling this, the useful framing is that the entitlement is considerably more certain than the timing. Assuming cash arrives in a particular quarter is the assumption most likely to be wrong.
Second-order effects: margins, working capital, importer earnings
A refund is a one-time cash inflow against duties already expensed, which means the accounting and the economics diverge in ways worth watching in earnings reports.
Companies that absorbed tariff costs into cost of goods sold will book recoveries as a benefit, often below the operating line or as a discrete item — which flatters reported earnings without indicating any improvement in the underlying business. Companies that passed tariffs through to customers face a more awkward question about whether the recovery belongs to them at all. And the working capital effect is real regardless: importers financed these duties for as long as two years, and getting that cash back materially changes the balance sheet of a duty-heavy importer.
The forward-looking question is separate and larger. If the effective tariff rate under replacement authorities settles lower than under IEEPA, gross margins improve prospectively. If it settles at a similar level through other statutes, the refund is a one-time item and nothing structural has changed.
Risks, uncertainty, and limits
The $175 billion figure is an estimate of total exposure, not a determined liability, and published estimates vary. How much is ultimately paid depends on how many importers file valid claims within the applicable windows and how the remaining proceedings resolve.
This is a general description of a process that is still developing and is not customs, legal or tax advice. Importers with exposure should be working from CBP guidance and their own counsel, not from a summary — the deadlines are entry-specific and missing one is not recoverable.
