CBP's April 2026 CAPE Guidance: The Rules Importers Need Before Filing

May 2026 update: CAPE Phase 1 is now live, and the first operating data shows why importers should treat CBP’s April guidance as a filing checklist rather than background reading. By the first week, trade reporting cited more than 75,000 CAPE declarations and millions of accepted entries, but also a large rejected-entry pool. Importers can now use ACE report ES-022 to monitor CAPE claim status and ES-701 to review reliquidations with refund and interest detail. For the reporting workflow, see our ES-022 and ES-701 claim status guide. If your file was rejected or only partly accepted, request an entry review before relying on CAPE alone.

CBP’s latest CAPE guidance changed the tone of the discussion.

Until early April, most commentary about CAPE focused on the headline: CBP was finally giving importers an electronic way to seek IEEPA refunds. That part is still true. But the April 10 and April 13, 2026 releases are more useful because they explain how the system will actually behave when filers start uploading claims.

The main takeaway is straightforward: CAPE simplifies submission, not judgment. That matches the current trade commentary as well. Baker Tilly framed CAPE as an intake system that moves the complexity downstream into validation, review, and refund defensibility. Husch Blackwell’s April 13 summary likewise focused on the strict validation rules and filing mechanics that importers now need to respect.

1. CAPE Is Not an “Any Broker, Any Spreadsheet” Tool

CBP’s April 13 guidance imposes two ownership rules that matter immediately:

• The filer must be the importer of record or the broker that filed the entry summary
• The upload must be a CSV of entry numbers only

That means a company cannot assume a new advisor can log in, dump a custom spreadsheet, and clean everything up inside ACE later. The filing party and the underlying entry data have to match from the start.

2. Phase 1 Has a Standard Lane and a Special-Handling Lane

The standard Phase 1 lane is still what most importers expected:

• Unliquidated entries can be set to liquidate 45 days after CAPE acceptance
• Recently liquidated entries can be reliquidated the next business day

But the April 13 guidance adds useful nuance:

• Extended, suspended, and under-review entries can remain in those statuses
• Warehouse and warehouse withdrawal entries stay on the normal warehouse liquidation track

So “not on the fast lane” and “fully excluded” are not always the same thing.

3. The Most Important Rejection Rules Are Now Public

CBP has made the validation logic far more concrete. A CAPE declaration can fail because the file is malformed, because the filer is not the correct party, or because individual entries fail the entry-level checks.

The most common blockers importers should screen for before filing are:

• No IEEPA Chapter 99 number on the entry
• Reconciliation flags or entry type 09
• Drawback activity or entry type 47
• Type 08 USMCA duty deferral
• Open or suspended protests
• Temporary importation under bond entries
• Pending-liquidation AD/CVD entries
• Entries more than approximately 80 days past liquidation

One practical result is that a CAPE declaration may be accepted only in part. ACE can remove the rejected entries and let the remaining entries continue. That makes pre-filing cleanup much more valuable than many importers first assumed.

4. ACH Setup Is Not a Minor Administrative Detail

This point deserves more attention than it usually gets.

CBP moved to electronic-only refunds on February 6, 2026. In the March 27 CSMS reminder, CBP said more than 12,300 certified refunds had already been rejected because the recipient did not have valid banking information on file.

For CAPE filers, that means:

• The refund recipient needs valid U.S. bank information in ACE before payment
• The recipient can be the importer or a designated 4811 notify party
• A technically valid CAPE declaration can still lead to a delayed payment if the ACH setup is incomplete

5. CAPE Does Not Eliminate Protest Strategy

This is where the filing strategy gets more subtle.

Many trade lawyers have been telling importers not to rely on CAPE alone, and the April 13 guidance reinforces that point. At the same time, CBP now says an open or suspended protest will cause CAPE to reject the entry.

That creates a practical fork:

• A protest can preserve rights inside the 180-day window
• But if the protest was filed solely for IEEPA refund purposes and the entry is still within CAPE’s 80-day lane, CBP says the importer may withdraw the protest and then use CAPE

That is not a contradiction. It is a sequencing problem, and importers should treat it that way.

For entries that fall outside the clean Phase 1 lane, use our CAPE, protest, or CIT decision framework before withdrawing a protest or assuming CAPE will solve the refund.

6. Refunds Will Be Consolidated, Not Paid Entry by Entry

CBP’s newer guidance is explicit that accepted refunds will be consolidated by:

• Importer of record or 4811 party
• Liquidation date

That means the payment you receive may not line up neatly with a single CAPE declaration. One refund can include entries from different declarations, especially where liquidation timing is uneven. CBP also says it checks for unpaid debts before issuing the refund, so the final payment can be lower than a simple “duties paid” total.

What Importers Should Do This Week

Before CAPE filing opens, the highest-value work is not waiting for launch day. It is operational cleanup:

1. Confirm who will file: the importer or the original broker
2. Confirm the refund recipient and ACH setup in ACE
3. Build an entry-number-only CSV from clean source data
4. Remove protest, drawback, reconciliation, and timing issues where possible
5. Decide how CAPE fits with protests and possible CIT litigation
6. Monitor ES-022 and ES-701 after filing so rejected entries do not sit unnoticed

That preparation work is what turns CAPE from a headline into an actual refund path.
