The Supreme Court tariff refund ruling: a procedural roadmap

As of July 18, 2026, the practical question is no longer whether the IEEPA tariffs survived. They did not. The Supreme Court’s February 2026 decision in Learning Resources struck down the IEEPA-based tariffs, while leaving the refund mechanics to be fought out elsewhere.[1] That distinction matters because the ruling did not disturb Section 232 tariffs on steel, aluminum, and autos or Section 301 tariffs on China; those duties remain outside this refund process.[2]

The missing remedial paragraph has done most of the subsequent work. Importers now have to map paid IEEPA duties against entry status, liquidation posture, CBP portal eligibility, and litigation-preservation choices. The Court of International Trade’s nationwide refund order, CBP’s CAPE portal, and the government’s pending Federal Circuit appeal do not describe one clean refund lane. They describe several lanes, with different consequences if an entry has already liquidated and if the statutory window to reliquidate has closed.

The dollar figures explain why the process is crowded, but they do not identify which entries are recoverable. Penn Wharton Budget Model estimated up to $175 billion in potential refunds, while the government cited $166 billion in its own filing.[3] CBP, by contrast, reported that approximately $85 billion in IEEPA tariff refunds was being processed through CAPE by late May 2026, with valid refunds generally issued within 60 to 90 days of filing.[4] Those are different measures: potential exposure, government-cited exposure, and money already moving through an administrative channel.

The entry status question comes first

The CIT order created the broad remedial frame, but entry status determines where the work begins. The useful first cut is not by importer, product, or amount paid. It is by whether the entry is unliquidated, liquidated within the 80-day voluntary reliquidation window, or liquidated outside that window.

That table is deliberately procedural. A paid IEEPA duty is not the same thing as a refund already available through CAPE. An entry within CAPE’s current scope is not the same thing as an entry insulated from appellate risk. And an importer that benefits from the CIT’s nationwide order may still have to decide whether to preserve a claim separately before a limitations period closes.

What the CIT order tried to do

Judge Eaton’s March 4, 2026 order at the Court of International Trade attempted to translate the Supreme Court’s merits ruling into nationwide refund administration. The order covered three groups: unliquidated entries, entries still within 80 days of liquidation, and entries already past that 80-day period.[5]

The third group is where the order moves from difficult administration into jurisdictional controversy. Customs law gives CBP a limited voluntary reliquidation window. Once that period has passed, the government’s position is that the CIT cannot simply order universal refunds for everyone; individual importers must have their own properly filed cases if they want relief outside that window.[5]

That is why the post-ruling docket filled even after a nationwide order. Law firm updates have reported thousands of CIT cases, with figures varying by source and timing; the research materials describe the range as roughly 2,000 to nearly 4,000 filed actions.[6] The filings are not just constitutional aftershocks. For many importers, they are preservation vehicles against the possibility that the Federal Circuit narrows the CIT’s nationwide remedy.

CAPE is processing refunds, but only for defined categories

CBP’s CAPE portal is the most concrete refund mechanism now operating. Phase 1 opened on April 20, 2026, for unliquidated entries and entries within 80 days of liquidation. Phase 2 opened on June 29, 2026, adding entries flagged for reconciliation where no reconciliation entry was on file.[4]

The portal matters because it turns the ruling into entry-by-entry payment processing. CBP’s late-May status figure, approximately $85 billion being processed through CAPE, shows that refunds were not merely theoretical by then.[4] But it also shows the danger of treating the portal as coextensive with the entire legal dispute. CAPE Phase 1 and Phase 2 do not yet answer every refund question raised by the CIT order.

CBP’s own guidance leaves several categories for further evaluation: entries involving drawback claims, entries with open protests, and entries not yet in ACE.[4] Those are not marginal details for brokers or in-house teams reconciling large client populations. They are the entries most likely to break a simple spreadsheet model because the refund record, protest posture, or data location may not line up with the portal’s current intake rules.

The portal sequence

For entries that fit the portal’s current rules, the operational question is whether the claim data matches CBP’s records closely enough to be processed. For entries outside current CAPE coverage, the question becomes preservation: whether the importer waits for a later phase, uses a protest or court filing, or has already done enough to keep the claim alive.

Why the 80-day line is doing so much work

The 80-day reliquidation window is not a convenience deadline. It is the boundary the government has chosen for its appellate attack on universal refunds. DOJ’s June 2, 2026 appeal to the Federal Circuit argues that the CIT lacks authority to order universal refunds for entries past that voluntary reliquidation window, and that importers outside it must pursue individual lawsuits.[5]

That appeal leaves three materially different positions as of July 18, 2026. First, some entries are already moving through CAPE. Second, some entries may be covered by the CIT’s nationwide order but remain exposed to a narrower appellate ruling. Third, some importers are filing individual CIT actions because relying on the nationwide order alone may not preserve the same position if the government succeeds.

The distinction is easy to lose in headline treatments of the Supreme Court ruling. The Supreme Court resolved the validity of the IEEPA tariffs. It did not issue entry instructions, override the liquidation system, or decide how far a nationwide refund remedy can reach once normal customs finality rules have attached.[1][5]

Preservation choices before early 2027

The limitations clock is the least forgiving part of the process. Norton Rose Fulbright’s refund analysis identifies a two-year statute of limitations running from the date of each entry, which means importers with the earliest February 2025 entries face deadlines beginning in early 2027.[7] That deadline exists even while the Federal Circuit appeal remains unresolved.

The preservation routes described in the cited materials are not interchangeable labels. Depending on entry posture, importers that have not already filed suit may look to a CBP protest, a direct action in the CIT, or, for unliquidated entries, a prior disclosure of clerical error.[6] Which path is available turns on facts the headline ruling does not supply: the entry date, liquidation date, protest status, prior filings, and whether CBP’s portal currently accepts the record.

This is also where the large lawsuit count becomes more understandable. If the government is right that entries past the 80-day window require individual actions, then waiting for CAPE expansion or appellate clarity could leave some importers with fewer options. If the CIT’s nationwide order survives intact, some filings may look redundant in hindsight. The problem is that hindsight will arrive after some entry-specific deadlines.

Interest is part of the refund calculation, not an afterthought

CBP guidance states that refund interest is calculated at IRS-determined quarterly rates from the date of estimated duty deposit to liquidation or reliquidation.[4] That means interest depends on the timing of the importer’s deposits and the entry’s liquidation or reliquidation history, not merely on the date of the Supreme Court decision.

For accounting and reserves, that timing can matter across a large entry population. Two importers with the same IEEPA duty total may not have the same interest amount if their deposits and liquidation dates differ. The cited guidance supports the calculation rule; it does not support a universal interest estimate.

What the appeal can still change

The Federal Circuit appeal is not a replay of the Supreme Court merits fight over IEEPA authority. The government’s June 2 filing targets the CIT’s remedial authority, especially as applied to entries outside the 80-day reliquidation window.[5] A ruling for the government would not necessarily disturb refunds already falling within CAPE’s narrower administrative categories, but it could substantially reshape the universe of entries entitled to relief without individual litigation.

That is the unresolved fault line beneath the current refund process. CBP is processing some claims. The CIT has ordered broader relief. Importers are filing protective suits. The appellate court has not yet resolved how much of the nationwide remedy survives ordinary customs finality rules.

Consumer class actions and broader tariff-policy consequences sit outside this procedural map. The research materials note more than 80 class actions filed, but no merits ruling on their core theories as of mid-2026. Those cases may matter elsewhere. They do not tell a customs broker whether an entry is in CAPE Phase 1, inside the 80-day window, or nearing a two-year limitations deadline.

The state of play

The Supreme Court’s February ruling created the entitlement question; the refund process now turns on source, status, and timing. Unliquidated entries and entries within 80 days of liquidation have a functioning CAPE route. Reconciliation-flagged entries without a reconciliation entry on file entered the portal in Phase 2. Drawback claims, open protests, and entries not yet in ACE remain in categories CBP has identified for further evaluation.[4]

For entries outside the cleanest portal categories, preservation remains live because the government’s appeal could narrow the CIT’s nationwide remedy. The early-2027 limitations pressure for February 2025 entries makes that uncertainty operational rather than academic.[7] The current refund process is therefore neither a simple mass payment nor a closed courthouse fight. It is a deadline-sensitive recovery process moving through CAPE, the CIT docket, and the Federal Circuit at the same time.
