IEEPA Refunds May Start May 12, But the Replacement-Tariff Picture Just Got Messier

U.S. Customs and Border Protection now says IEEPA refund ACH transactions may begin as early as Tuesday, May 12 — one day later than the “on or about May 11” timing that came out of CBP’s April 28 status update to the Court of International Trade. The new date appeared in CSMS #68536553, the May 4 message outlining the ACE reports importers and brokers can use to monitor CAPE refund claims.

What that date is actually telling importers is more nuanced than the headline suggests. As of April 26 — six days into the CAPE rollout — importers and brokers had submitted roughly 75,300 CAPE Declarations. About 47,300 passed file-level validation, covering more than 11.2 million entries that entered processing. The narrower refund-stage number was about 1.74 million entries: those accepted entries that had already been liquidated and were in the refund process. That is the operational read for the week ahead: May 12 is when the cleanest, already-liquidated filings start cycling into ACH disbursement. For everyone else, the date is a forcing function for what gets fixed this week.

Below is the checklist a trade-compliance lead should be working through before Friday, the three policy storylines that change the universe of exposed HTS lines, and the next two procedural deadlines that matter — the early June appeal window on Judge Eaton’s underlying refund order (DOJ’s deadline lands around June 6 per ST&R’s reading), and the now-contested July 24 expiry on the Section 122 tariffs that have stepped in where IEEPA used to sit.

What CBP actually said on May 4

The Reuters wire that picked up the May 12 date traces back to CBP’s May 4 CSMS message, which lists several ACE reports now relevant to CAPE refund monitoring. Four are worth knowing by name, because they cover different stages of the refund lifecycle:

ES-022 CAPE Entry Summary Report — links CAPE Declaration, entry, and refund numbers, and breaks refund amounts out into principal and interest. This is the first place to look to confirm a CAPE filing has produced a refund record at all.
REV-603 Trade Refund Report — tracks refund status after Treasury receives the approved claim, including states like Sent to Treasury, Treasury Issued, Funds Diverted, and Check/ACH Returned. Not just successful refunds — also where you’ll find diversions and returns.
REV-613 ACH Rejected Refunds Report — flags refunds rejected specifically because ACH refund enrollment is incomplete. The clean diagnostic for “filing was correct, payment couldn’t land.”
REV-615 CAPE Details Refunds Report — entry-summary-level detail tied to CAPE Declarations that have been transmitted to Treasury. Useful for reconciling refund line-items against the original entry list.

All four live under ACE Reports for Importer sub-account users. The practical sequence: ES-022 first to confirm CAPE → entry → refund linkage, REV-603 for Treasury status, REV-615 for line-item detail once funds are moving, and REV-613 separately if you suspect ACH rejection is the blocker. If your team has not yet pulled any of them, that is the first thing on the list before May 12.

One more piece of context that the headline tends to flatten: $166 billion is the upper bound of CBP collections subject to refund, against a universe court filings put at roughly 330,000 importers and more than 53 million entries. Phase 1 is deliberately scoped to the cleanest segment of that universe — certain unliquidated entries and entries within 80 days of liquidation. The categories explicitly outside Phase 1 are not part of the May 12 window at all: reconciliation entries (including Type 09 reconciliation summaries), entries subject to AD/CVD pending liquidation under 19 U.S.C. § 1504(d), entries with final liquidation older than 80 days, Type 08 duty deferral, Type 23 TIB, drawback-flagged entries, and entries currently under open or suspended protest. Those will be addressed in later phases or through alternative remedies.

The five-day checklist

For trade-compliance and customs leads filing direct (or supervising a broker who is), this is the work that determines whether your entries are positioned for the earliest ACH window beginning May 12 or pushed into a later refund cycle.

1. Confirm ACE Portal access and who’s filing

Confirm who has ACE Portal access for the relevant IOR, who is responsible for filing, and who is responsible for monitoring CAPE activity. CBP allows the IOR or the broker that filed the original entry summaries to submit CAPE Declarations — not both, and not a third party. The CAPE tab is exposed to the Importer, Organizational Broker, and Filer sub-accounts. Importer sub-account access is the relevant one for monitoring the four ACE reports above. ACH refund enrollment is a separate concern, covered in the next item, and is the more common payment-stage failure point.

2. Verify ACH banking is current

CAPE refunds are issued electronically by ACH under CBP’s electronic refund rule; ACH enrollment is required to avoid disbursement delay (limited hardship waivers exist under 31 CFR Part 208 but should not be assumed for normal cases). Bank account information has to be designated for refunds inside the ACE Portal before disbursement triggers — if it is missing or stale, the refund will surface in REV-613 as a rejection rather than in REV-603 as a payment, which means the filing was correct but the money cannot land. This is the single most preventable failure mode in the system.

3. Pull the IEEPA exposure list from ES-003

The Entry Summary Details Report (ES-003) in ACE is where to filter on HTSUS Chapter 99 provisions 9903.01.XX and 9903.02.XX to surface entries that carried IEEPA duties. Trade compliance teams that have not yet built this list should treat it as the master input to every CAPE Declaration this quarter, not a one-time exercise.

4. Make the protest-vs-CAPE decision before filing

Entries currently under protest are excluded from Phase 1 CAPE processing. CBP has indicated that protests filed solely to preserve IEEPA refund rights can be withdrawn so the underlying entries can move through CAPE — but the choice has to be made deliberately, and in some cases the protest may need to be unsuspended before it can be withdrawn. Any entries you want positioned for the earliest May 12 ACH window with active protests need that decision made this week.

5. Verify the data before you file — do not amend after

CAPE Declarations cannot be amended. A formatting error or a wrong entry number can cause the submission to fail validation, and rejected entries have to be corrected and resubmitted on a separate Declaration. Each Declaration caps at 9,999 entry numbers; brokers can include entries from multiple IORs in a single file. CBP’s validation list also screens out a long set of non-Phase-1 categories: reconciliation, drawback, Type 08 duty deferral, Type 23 TIB, open or suspended protests, AD/CVD entries pending liquidation, entries more than 80 days past final liquidation, and entries with goods-value issues on the IEEPA HTS line. The gap between the 11.2 million entries in processing and the 1.74 million already in the refund process is therefore not just a payment-timing issue — it reflects liquidation status, eligibility, and processing stage, and the work to close it has to happen at the entry level, not the declaration level.

If your team is reconciling tariff-line exposure across hundreds of inbound entries while CBP and your broker are working different copies of the truth, a 30-minute walkthrough of how shipment-level milestone visibility ties back to entry numbers in your TMS might cut the reconciliation cycle.

Three policy storylines stacked behind May 12

The May 12 date is happening inside a wider tariff environment that is still moving. None of the items below changes the CAPE filing checklist for this week — but each of them changes either which HTS lines are exposed next, or whether the refund process itself faces appellate stay risk.

USTR’s four-day Section 301 hearing on excess factory capacity

The U.S. Trade Representative opened a four-day hearing on Tuesday, May 5, on its Section 301 investigation into structural excess capacity in 16 economies — including China, the European Union, Japan, South Korea, Mexico, and Vietnam. Domestic industries are pushing for higher tariffs to slow imports from countries with overhang capacity; import-dependent and agriculture groups are pushing back. Per Reuters’ coverage of the hearings, trade watchers widely expect the probe to lead to new import duties as the administration looks to rebuild the tariff leverage lost after the Supreme Court’s February 20, 2026 ruling against the IEEPA-based program — though that is an expectation about likely outcome, not a formal USTR result. For sourcing teams, the operational read is which HTS lines could pick up Section 301 exposure if and when this probe yields measures, and the shape of the answer will start to come into focus this week.

EU auto tariff: delayed, not defused

On Friday, May 1, President Trump threatened to raise tariffs on EU-made cars and trucks from 15% to 25%, accusing the EU of reneging on the trade accord struck last year. That immediate threat has since been pushed out: on May 7, Trump gave the EU until July 4 to approve and implement the deal before facing “much higher” tariffs. European Commission President Ursula von der Leyen said both sides remain committed to the agreement, while EU implementing legislation remains unfinished. For BCO importers and forwarders moving EU-origin autos, parts, or assemblies, this remains an operational story to watch — separate from CAPE, but no longer on a this-week tariff-hike timeline.

Early June — the appeal window on Judge Eaton’s order

The government’s appeal window on Judge Richard Eaton’s amended order — the order directing CBP to liquidate or reliquidate IEEPA entries without regard to those duties, including entries already finally liquidated — runs into early June. ST&R identifies June 6 as the Department of Justice deadline. A successful appeal could result in a stay of the broader refund process and significantly delay payments. Phase 1 is structured around the cleanest, least-contested entries precisely because of this appellate exposure: CIT has suspended the order’s immediate-compliance requirement to allow phased rollout, but the underlying ruling remains live until the appeal window closes.

What’s replacing IEEPA in the meantime

One detail worth flagging because it tends to fall out of refund-focused coverage: with IEEPA no longer available as a tariff authority for the struck-down program, the administration has leaned on other trade statutes — but those replacement tools now carry their own legal and timing risk.

The clearest example is Section 122, which authorizes temporary import surcharges for up to 150 days unless Congress extends them. The current Section 122 tariffs took effect February 24 and are still scheduled to terminate July 24, 2026. But on May 7, the Court of International Trade ruled that the administration’s 10% global tariffs under Section 122 were not justified. The ruling was narrow in remedy: it blocked collection only for the two private importers and the State of Washington that brought the case. For other importers, the 10% Section 122 tariffs remain in place while appeal risk plays out. The operational point is that Section 122 is no longer just a countdown issue; it is also a litigation-risk issue.

Section 232 and Section 301 remain the more durable replacement avenues. Section 232 has already been used for major industrial categories such as steel, aluminum, autos, and auto parts, while other strategic sectors remain under active policy attention. Section 301 is where new exposure is most likely to come from in the next 90 days, as this week’s excess-capacity hearing feeds into eventual Federal Register notices. For a trade-compliance team, the practical implication is that even if a CAPE refund clears in the 60-90 day window CBP has set, the same product line may pick up new duties under a different statutory authority before the refund hits.

The exposure picture for the next 90 days is therefore a reshuffling by HTS line, with different appeal and refund dynamics attached to each statutory authority — not a clean unwind of the IEEPA-era duty stack.

The decision a compliance lead should be defending Friday

Three things, sequenced:

First, the queue position for May 12. Which entries on your IEEPA exposure list have been filed in CAPE, which have been validated, and which are stuck in REV-613 because of ACH setup. If validated, already-liquidated entries exist and ACH is current, those are the entries best positioned to disburse on or shortly after May 12. If anything is in REV-613, that is the most immediately fixable failure mode this week.

Second, the protest decisions. Each entry that sits under a protest filed only to preserve IEEPA rights is one decision: withdraw the protest and route through CAPE for faster refund, or hold the protest because it is preserving something else. The status quo (protest active, CAPE blocked) is the worst position to leave entries in past this week.

Third, the forward exposure map. Pull a current view of which inbound product lines could pick up Section 232 inclusions or Section 301 duties from this week’s USTR hearing, and which lines are still exposed to the contested Section 122 surcharge while appeals play out. The operational point is not to predict the outcome but to know which HTS lines you would need to re-cost if any of three things happen: EU vehicle tariffs are revived after the July 4 deadline, the USTR probe yields product-specific Section 301 measures, or the IEEPA appeal lands a stay before the early-June DOJ deadline.

None of those three is a hypothetical for next quarter. Two of them are decisions that will start being made this week.
