The CAPE system launches April 20, 2026. Most importers think they are preparing for a refund. They should be preparing for a review.
The result of the Supreme Court's decision*, an estimated $165 to $175 billion in unlawfully collected duties must be returned to roughly 330,000 importers across more than 53 million entries. The Court of International Trade directed CBP to begin processing refunds, and CBP responded by building a purpose-built system called CAPE -- the Consolidated Administration and Processing of Entries -- inside its Automated Commercial Environment (ACE) portal.
*Supreme Court's landmark 6-3 ruling in Learning Resources v. Trump on February 20, 2026, the International Emergency Economic Powers Act (IEEPA) was determined not to be a valid way to impose tariffs. The IEEPA's broad "regulate" language does not convey taxing authority via tariffs.
What is CAPE: Consolidated Administration and Processing of Entries (CAPE) refunds process with the ACE Portal. CAPE is not a payment tool. It is a review engine with a refund function attached.
On the surface, the process looks straightforward: upload a CSV of entry numbers, wait 60 to 90 days, receive your refund electronically via ACH. But trade compliance professionals who have studied the mechanics of the system are sounding alarms.
CBP has described CAPE as having four integrated components:
Claim Portal: Importers or their authorized brokers upload a CSV file listing entry numbers (up to 9,999 per declaration). The system validates the file format, confirms the filer's authorization, and checks each entry number against ACE records.
The critical distinction is in the third step. The real process is not "upload then refund." It is "upload, then review, then liquidation or reliquidation, then refund." That middle step -- the review -- is where things get complicated.
Trade professionals who have been tracking the CAPE development through court filings and CBP declarations from Brandon Lord, Executive Director of Trade Programs at CBP, are pointing to several features that reveal CAPE's true design intent.
CBP has been conducting intensive testing across the four CAPE components. In plain terms, they are stress-testing how the system handles entries where the data does not align cleanly -- mismatched classifications, inconsistent country of origin declarations, or duty calculations that do not reconcile.
Entries subject to antidumping or countervailing duties are excluded from Phase 1 automation entirely. When they are eventually processed, a human reviewer will walk through each entry line by line. For importers with complex duty structures, this is a significant bottleneck.
CBP has been candid with the Court about the operational challenge. The agency is not going to review every single entry with the same intensity. Instead, the system is designed to flag entries that warrant closer examination -- the ones that look worth reviewing.
Every CAPE claim, every adjustment, every recalculation, and every decision is now recorded in one place. CBP has not characterized this as an audit mandate. But it is a system that evaluates claims before money moves, can revisit them after money moves, and applies pressure where something does not look right.
The biggest mistake you can make is treating this like a refund exercise. It is an audit you have not had yet.
The CSV upload is the simplest part of the entire process. The complexity begins once ACE starts recalculating your entries without IEEPA duties.
When the system strips the IEEPA Chapter 99 codes, it does not just reduce your total. It recalculates the entire entry through ACE's standard validation logic -- the same logic that reviews every commercial entry filed in the United States. That means your HTS classifications, your declared values, your country of origin determinations, and your duty calculations are all exposed to fresh scrutiny.
Importers with clean entries and accurate classifications should move through the process without incident. But those who may have used IEEPA tariff codes to sidestep obligations under other programs -- Section 232 steel and aluminum duties, Section 301 China tariffs, or country of origin requirements -- face real exposure.
One trade expert put it bluntly: if CBP catches incorrect tariff classifications where importers were paying IEEPA to avoid 232, 301, or proper country of origin determinations, the consequences extend well beyond a delayed refund.
Each piece of data submitted through CAPE flows into ACE, where it runs against audit criteria that CBP has been building and refining for years. These are not new capabilities -- ACE has long had internal tools to flag anomalies and concerns on entries. The CAPE data is not processed in isolation. It feeds directly into the same system, and newly recalculated entries will undergo the same data reviews as any other filing. It is iterative: submit, validate, recalculate, review, and potentially flag.
Beyond compliance risk, there is a practical operational concern that is not getting enough attention: system capacity.
An estimated 23,000 importers (or their brokers) are expected to begin filing CAPE declarations on April 20. If a significant portion attempt to upload on day one, the ACE Portal could face serious strain. CBP has been transparent about the phased development timeline and the intensive testing underway, but the real-world load of tens of thousands of simultaneous filings is an untested variable.
Importers and brokers should plan their filing strategy with this in mind. There is no advantage to being first in line if the system is overwhelmed. A measured approach -- ensuring data quality before uploading -- will serve importers far better than a rush to file.
The compliance community is also watching for longer-term consequences. Several legal experts have noted that the CAPE process could generate referrals for formal audit activity or even enforcement actions.
Refund claims of this magnitude will attract scrutiny. Large-scale recovery efforts tied to a high-profile Supreme Court decision are precisely the kind of activity that draws focused reviews. Companies that proactively validate their import practices and documentation will be far better positioned than those who treat CAPE as a simple administrative exercise.
Some attorneys have raised the possibility that the review process could eventually feed enforcement through mechanisms like the False Claims Act, particularly where refund claims are found to rest on inaccurate underlying data. The key shift in thinking is that refunds trigger scrutiny, not closure. The process does not end when money moves -- it starts there.
As one observer noted, this is CBP's opportunity to demonstrate that its audit capabilities can identify discrepancies efficiently. The agency has been investing in auditors and data analytics for years. CAPE gives them a structured, centralized dataset to work with.
For businesses shipping goods into the United States -- including Canadian companies managing US import compliance -- the action items are clear:
CBP no longer issues paper refund checks. All refunds are electronic. If your banking information is not on file in ACE, your refund will sit in reject status until it is. As of late March, roughly 78 percent of affected importers had completed ACH enrollment.
Do not submit a CAPE declaration until you have reviewed the underlying data. Verify HTS classifications, country of origin declarations, and duty calculations. If any entries relied on questionable classification strategies, address those issues before they are exposed during recalculation.
Phase 1 covers most unliquidated entries and entries liquidated within the last 80 days -- approximately 63 percent of all affected entries. Entries involving AD/CVD duties, drawback claims, reconciliation, or final liquidation beyond the 80-day window are excluded and will be addressed in future phases.
This is not a task for any single function. The refund has financial planning implications, compliance risk implications, and potential legal exposure. Treating it as a cross-functional project is the only responsible approach.
There is no benefit to filing on day one if your data is not clean. A well-prepared submission filed in the second or third week will process more smoothly than a rushed filing that triggers rejection or review flags.
CBP deserves credit for building CAPE as quickly and logically as they have. Returning $165 billion or more to 330,000 importers across 53 million entries is an unprecedented operational challenge, and the phased, systematic approach reflects serious institutional effort.
But importers need to understand what they are walking into. CAPE is not a refund portal in the way most businesses are imagining it. It is a structured process with a review engine at its core. The CSV upload is the front door. What matters is what happens on the other side.
Those who treat this as a compliance exercise -- with defensible positions, clean data, and coordinated preparation -- will recover their money efficiently. Those who treat it as a CSV upload problem will discover that they have not just filed for a refund. They have created a file with their name on it.
