CBP Is Rejecting 15% of CAPE Refund Claims. Here's Why — And How to Not Be One of Them

The Number That Should Alarm Every Importer

CBP has now officially confirmed: 15% of all CAPE Declarations filed since April 20, 2026 have been rejected.

With approximately 56,497 importers pre-registered and tens of thousands of declarations filed in the first 10 days, a 15% rejection rate means thousands of companies are now scrambling to figure out what went wrong — while their 80-day window keeps running.

A rejection is not the end. You can file a new CAPE Declaration with the corrected entries. But every day you spend diagnosing the rejection, fixing the data, and resubmitting is a day off the clock for entries near the 80-day liquidation cutoff.

For a company with $2 million in refunds across 500 entries, a rejection that delays filing by three weeks could mean dozens of entries aging out of Phase 1 eligibility entirely.

The Five Reasons CBP Rejects CAPE Claims

Based on CBP guidance, law firm analysis from Baker Tilly, Snell & Wilmer, and Norton Rose Fulbright, and the specific error codes CBP has published, here are the five most common rejection causes:

1. Data mismatch at the line level. The single most common rejection trigger. CAPE compares your submission against CBP's original entry summary records at the individual line item level. If your HTS code, entered value, or quantity is even slightly off from what CBP has on file — the "Unable to calculate duty" error fires and that entry is rejected or routed to manual review.

Post Summary Corrections (PSCs) are a common culprit. If your broker filed a PSC after the original entry, your data may reflect the original values while CBP's system shows the corrected values. CAPE cannot reconcile the difference automatically.

2. Including ineligible entry types. Phase 1 has a specific list of entry types it will not process: entries with final liquidation outside the 80-day window, entries flagged for reconciliation under 19 USC 1484b, entries with open protests, entries subject to AD/CVD orders (approximately 166,000 entries totaling $2.9 billion in IEEPA duties), warehouse entries, and extended or suspended entries (these can be included but won't be processed until their status resolves).

Including any of these in your CAPE Declaration does not reject your entire declaration — but those specific entries get rejected, and if the errors are widespread enough, they can trigger validation failures that affect clean entries.

3. ACH not enrolled before filing. CBP has now confirmed: if you do not have ACH bank enrollment completed in your ACE Importer sub-account before filing, your refund cannot be issued even if your declaration is accepted. Some importers filed declarations before completing ACH enrollment. Their claims are technically accepted but payment is blocked.

4. Duplicate entries. Each entry can only appear on ONE accepted CAPE Declaration. If you submitted multiple declarations and the same entry number appears on more than one, all subsequent declarations containing that entry will be rejected for that entry. This is particularly common for brokers filing on behalf of multiple clients where the same entry was filed by different parties.

5. Account and authorization issues. Only the original IOR or the licensed customs broker who originally filed those entries can submit a CAPE Declaration. Companies that hired new brokers or legal counsel to handle their CAPE filing — but whose original entries were filed by a different broker — may face authorization rejections.

What a Rejection Actually Means for Your Timeline

When CBP rejects a CAPE Declaration entry, here is what happens:

You receive a rejection notification in ACE. The rejected entries are NOT locked — you can file a new CAPE Declaration with corrected data. But you cannot include those entries on a new declaration until you have fixed the underlying issue.

The clock does not stop while you diagnose and fix.

If you have entries from late January or early February 2026 that are approaching the 80-day window, and your declaration was rejected on April 25, you may have as few as 2-3 weeks to fix the data and resubmit before those entries age out.

For large importers with complex supply chains, diagnosing which of the five causes triggered the rejection — and at which line items — is not a weekend project. It requires someone with direct ACE access and experience reading CBP entry summary data.

The Math on What a Rejection Costs You

Take a company with $3 million in estimated refunds across 800 entries.

15% rejection rate applied to their filing = approximately 120 entries rejected.
120 entries × average $3,750 refund per entry = $450,000 in refunds blocked.

If those 120 entries are near the 80-day window and can't be resubmitted and accepted in time, that $450,000 moves to Phase 2 — which has no announced timeline — or requires litigation in the Court of International Trade.

A pre-filing audit that catches those 120 problematic entries costs a fraction of $450,000.

What to Do If You've Already Been Rejected

If your CAPE Declaration was rejected:

Step 1. Log into ACE and pull the rejection report. Identify which specific entries were rejected and what error codes fired.

Step 2. For "Unable to calculate duty" errors — pull the original CF 7501 for each rejected entry and compare line by line against your submission data.

Step 3. For ineligible entry type rejections — remove those entries from your next declaration. They won't qualify for Phase 1 regardless.

Step 4. Check your liquidation status on all rejected entries. Any approaching the 80-day window need to be prioritized immediately.

Step 5. Fix the data, build a corrected CSV, and resubmit a new CAPE Declaration. You cannot amend the rejected one — a new declaration is required.

Step 6. If you cannot identify the cause of the rejection or lack direct ACE access, get professional help before the window closes.
