The Real IEEPA Refund Fight Is Over Finally Liquidated Entries
The Supreme Court invalidated the administration's claimed IEEPA tariff authority in February, but it did not decide how refunds must be paid. The June 10 Wyden and Markey letter adds political pressure, yet the binding fight is judicial, over whether CBP must refund finally-liquidated entries held by importers who never brought suit.

The refund fight has moved from tariff authority to remedial reach
On June 10, 2026, Finance Committee Ranking Member Ron Wyden and Small Business Committee Ranking Member Ed Markey sent CBP Commissioner Rodney Scott a letter demanding that International Emergency Economic Powers Act tariff refunds be paid without further delay, with written answers due June 24. The letter is factually grounded and politically sharp, but it is non-binding minority-party oversight. The constraint actually shaping CBP behavior is the litigation in front of Judge Richard Eaton at the Court of International Trade and the government appeal now at the Federal Circuit. The Supreme Court invalidated the administration's claimed IEEPA tariff authority on February 20, 2026, but it did not decide how refunds must be paid. What is still live is the remedy, and its hardest part is whether CBP must refund finally-liquidated entries held by importers who paid the tariffs but never filed suit.
That distinction controls how an importer should act. A refund path that is settled for one category of entries is contested for another, and the senators' framing of refunds as legally owed and automatic describes what they argue the CIT orders require rather than a refund obligation CBP currently accepts across the board.
The letter is a narrow two-signer demand, not a multi-committee instruction
This is a Wyden and Markey letter signed by the two of them, and it should not be conflated with the earlier multi-signatory letters or with the Tariff Refund Act co-sponsor list. It accuses the administration of intentionally slowing refunds, stating that the episode raises questions about whether the administration is slowing the process to retain access to what the senators describe as unlawfully collected funds, and that CBP has slow-rolled implementation from the outset. It poses eleven questions. The first few track timing and dollars. The sharper ones reach past timing into internal CBP refund-prioritization guidance, CBP and DOJ communications about litigation strategy, Treasury and OMB communications about retaining or repurposing unreimbursed tariff revenue, and a category-by-category breakdown of refund progress across unliquidated, non-final liquidated, and finally-liquidated entries.
The letter's dollar figures are the ones to cite for the senators' demand, roughly $20.6 billion refunded, about $146 billion remaining, and about $166 billion collected in total. Those figures should still be treated as moving implementation numbers rather than a live CBP status report. Commissioner Scott is Senate-confirmed and accountable to these committees, which is why the senators can demand written answers, but the demand carries no enforcement mechanism of its own.
The Supreme Court held IEEPA did not authorize the tariffs and left the refund mechanics to the CIT
On February 20, 2026 the Supreme Court held 6-3 in Learning Resources v. Trump, consolidated with the V.O.S. Selections case, that IEEPA does not authorize tariffs. The majority did not address refunds. Only the dissent flagged the refund exposure and warned the process would be a mess. The mechanics fell to the Court of International Trade, where Judge Eaton has run implementation through a sequence of lead cases. Through the March refund-order sequence, Eaton directed CBP to process affected entries without the invalidated tariffs, and the later amended order brought finally-liquidated entries into the remedial frame. He suspended immediate compliance to let CBP build its refund system, then on May 27 issued an order to show cause and ordered testimony from CBP.
The government is fighting the reach of that order. It moved at the CIT on May 29 and pursued Federal Circuit review in early June, arguing under CASA that the CIT cannot extend relief to non-party importers through a universal refund injunction, particularly for finally-liquidated entries. The testimony dispute narrowed along the way. The court allowed substitute testimony from senior CBP officials, the government withdrew its mandamus petition, and CBP Executive Assistant Commissioner Susan Thomas testified at the June 9 hearing.
The contested category is finally-liquidated entries held by importers who did not sue
The government sorts the roughly $166 billion into three buckets. Unliquidated entries are refunded through the new system. Finally-liquidated entries where the importer sued are acknowledged as owed, pending system work. The third bucket, finally-liquidated entries of importers who did not litigate, is the contested one, and the government argues it exceeds CIT jurisdiction and equity under CASA. This is the live fault line, and it tracks the same distinction the senators drew in their eleventh question.
The dispute also drew a class-certification move. On June 4, Terry Precision Cycling and others moved to certify a class of importers whose refund claims are not currently eligible for the consolidated refund path, seeking to extend that path to class members. The government response is due June 25, and Eaton signaled reluctance at the June 9 hearing. The class question is unresolved as of June 13, 2026.
How the refund actually moves, and why it is not automatic
Refunds run through liquidation and reliquidation, consolidated in the CBP CAPE process inside ACE. On an accepted CAPE declaration, the system strips the IEEPA Chapter 99 lines, recalculates, and reliquidates with a consolidated refund to the importer of record. Interest runs under 19 U.S.C. 1505(c), compounded daily, at quarterly rates. For the second quarter of 2026 the overpayment rates fell to 6 percent for non-corporate filers and 5 percent for corporate filers, down from 7 and 6 percent in the first quarter. On a payment held a year or more, that interest reaches tens of thousands of dollars per million refunded. Interest partly offsets delay, but it does not remove the need to preserve the correct refund path.
Phase 1 launched on April 20, 2026 and covers roughly 63 percent of entries, including unliquidated entries and recently liquidated entries within the CAPE Phase 1 path. Importers should not treat the outer edge of the 90-day voluntary reliquidation period as a safe filing target, and the more conservative operating assumption is that CAPE timing and protest timing must be calendared separately. Refunds generally arrive 60 to 90 days after acceptance, by ACH only, which means the importer of record must have ACE and banking details ready. More than 1,800 refunds have stalled for missing bank information alone. This is the core of the senators' grievance, because CAPE is consolidated but it is not a fully automatic refund process for every affected importer. Until a court or CBP requires a broader automatic process, entry-level action and deadline monitoring remain necessary.
The phase timeline does not resolve the legal-authority question
At the June 9 hearing, Thomas testified that Phase 2 for reconciliation entries launches June 29, and that Phase 3 programming for finally-liquidated entries may be technically ready by late July. The timing matters, but technical readiness is not the same as authority to pay. CBP has separately asserted that it lacks authority to refund finally-liquidated entries absent an importer-specific judgment, a position the Sheppard Mullin analysis describes as a reversal from its earlier signaling of later-phase handling. So late July is a programming milestone, not an automatic resolution of the contested category. Whether those importers get paid without their own judicial relief depends on the Federal Circuit appeal, a new CIT order, or class certification rather than on CBP finishing its software.
What importers should do now
The practical rule is entry-level triage rather than treating IEEPA refund as one bucket. For unliquidated entries or entries still within the CAPE Phase 1 path, importers should assess CAPE declarations first, because that is the fastest administrative route and it captures roughly 63 percent of entries, with interest, once ACE and ACH enrollment is in place. For entries outside that path but still within 180 days of liquidation, importers should consider protective protests under 19 U.S.C. 1514 where the protest path remains available, and should calendar the protest deadline separately, because a CAPE filing should not be treated as preserving protest rights and a rejected or delayed declaration may not toll that clock. For finally-liquidated entries outside the current path, the question becomes litigation posture, because under the government's current position a non-litigating importer in this category may need importer-specific judicial relief unless the Federal Circuit appeal, a new CIT order, or class certification changes the posture, and the two-year CIT statute under 28 U.S.C. 2636 is the outer limit to watch.
Beyond triage, keep entry summaries, proof of payment, and classification and valuation support, and expect netting against Section 232 and Section 301 underpayments, AD/CVD, and debts owed to CBP. Refunds reach only the importer of record or a Form 4811 notify party, so downstream parties that actually bore the tariff cost have no direct CBP claim and must recover by contract. AD/CVD-suspended and reconciliation entries sit outside Phase 1 and require manual processing. The live dates to track are the senators' answer deadline on June 24, the class-certification response due June 25, Phase 2 on June 29, Phase 3 readiness in late July, and any Federal Circuit action on the pending appeal. A Federal Circuit stay could suspend the consolidated refund path entirely.
Bottom line
The Supreme Court invalidated the administration's claimed IEEPA tariff authority in February, but the refund fight is unresolved, and it is being decided in court rather than by Senate oversight. CBP is paying unliquidated entries through CAPE while arguing it cannot administratively refund finally-liquidated entries held by importers who did not sue. The June 10 Wyden and Markey letter sharpens the political pressure and sets a June 24 answer deadline, yet the binding pressure on CBP is judicial, coming from Eaton and the Federal Circuit. Importers should sort their entries by liquidation status now, assess CAPE where eligible, preserve protest rights separately, and weigh litigation exposure for finally-liquidated entries rather than wait for an automatic refund that may not come for the contested category.
Caveats
Several figures are moving targets and should be refreshed against the latest CBP declaration before relying on them, including the amount in process, the amount moved to Treasury, and the validated and reliquidated entry counts. The June 10 letter is minority oversight rather than a binding instruction, and its legally owed and automatic framing reflects the senators' reading of the CIT orders, which are themselves partly suspended and under appeal. The Phase 3 late-July date is technical readiness, not a commitment to pay the contested category. The Federal Circuit could act on the appeal at any time, including a stay that suspends the consolidated refund path, and the class-certification ruling could change which importers have a route to refund.
