How the CAPE Refund System Works
U.S. Customs and Border Protection (CBP) has recently unveiled its strategy for processing CAPE refund claims on duties collected under the International Emergency Economic Powers Act (IEEPA). Specifically, in a March 12, 2026 filing with the Court of International Trade (CIT), the agency detailed the CAPE system—a new, purpose-built platform designed to manage refunds at scale.
The CAPE refund system (Consolidated Administration and Processing of Entries) operates within CBP’s existing Automated Commercial Environment (ACE) framework. Related: Our analysis of the Supreme Court IEEPA ruling explains how IEEPA duties ended on February 24, 2026. By understanding how the CAPE refund process works—and by preparing your data now—you will position yourself to secure your refund quickly once the system launches.
What Is the CAPE Refund System?
The CAPE refund system is a dedicated module within ACE that CBP designed specifically to manage IEEPA duty refunds at scale. Rather than processing refund requests manually and one-by-one, the CAPE refund process enables bulk submissions, automated validations, and systematic refund distribution.
Key advantage: The system handles massive volumes simultaneously, allowing CBP to return refund money to the market as quickly as possible. For importers dealing with substantial IEEPA duty exposure, the CAPE refund system represents a dramatic improvement over manual processing.
The Four Pillars of the CAPE Refund System
CAPE’s architecture rests on four integrated functional components:
1. CAPE Refund Claim Portal
First, a web-based interface serves as the starting point where importers and customs brokers submit IEEPA refund requests—called CAPE Declarations—directly into the system. Importantly, this portal functions as the single entry point for all CAPE refund claims. Learn more about ACE Portal access requirements.
2. Mass Processing via CSV Upload
Second, rather than submitting entries individually, filers upload a Comma-Separated Values (CSV) file containing all entry summaries eligible for CAPE refund processing. Notably, this capability allows ACE to process massive volumes of entries in a single batch operation.
3. Review and Liquidation in the CAPE Refund System
Subsequently, ACE systematically removes the specific IEEPA Chapter 99 line items from each entry, recalculates the duties owed, and schedules entries for liquidation or reliquidation. Crucially, CBP conducts internal reviews during a designated holding period before finalizing the duty calculations in the CAPE refund process.
4. Electronic CAPE Refund Distribution
Finally, once entries are liquidated or reliquidated, they flow into ACE Collections. From there, the system consolidates payments by importer and date, then distributes CAPE refunds electronically to the designated recipient. For more details on ACE Collections, consult CBP’s official guidance.
How the CAPE Refund System Workflow Operates
Understanding the step-by-step CAPE refund process will help you anticipate processing timelines and structure your submission data correctly.
Step 1: File Validations for CAPE Refund Submissions
When you upload a CAPE Declaration for the CAPE refund system, ACE immediately performs a series of file-level validations:
- Technical checks: ACE verifies the CSV file is properly formatted and uncorrupted
- Authorization checks: The system confirms that the filer is either the Importer of Record (IOR) or an authorized customs broker
- Completeness checks: ACE ensures all required information is present
If validation fails: Consequently, ACE rejects the entire CAPE refund submission and highlights the specific errors for correction. Clearly, you must then fix these errors and resubmit.
Step 2: Entry-Level Validations in CAPE Refund Processing
Once the file passes, the system evaluates every individual entry in the CSV:
- Existence check: ACE confirms the entry actually exists in the ACE database
- IEEPA content check: The system verifies that at least one IEEPA Chapter 99 Harmonized Tariff Schedule (HTS) line item appears on that entry
If an entry fails: ACE removes it from the batch, but importantly, processing continues for valid entries in your CAPE refund system submission. Notably, you can correct and resubmit failed entries in a subsequent CAPE Declaration.
Step 3: Mass Processing & Recalculation via CAPE Refund System
Next, validated entries move into automated processing. CAPE then:
- Strips away all IEEPA Chapter 99 tariff lines
- Recalculates final duty amounts as if IEEPA duties had never existed
- Runs standard duty validations again
This batch processing approach enables CBP to handle large volumes simultaneously. Consequently, the CAPE refund process returns money to importers far more rapidly.
Step 4: Review and Liquidation/Reliquidation in CAPE Refunds
After processing is completed, the entries are scheduled for liquidation or reliquidation—but notably, not immediately. ACE sets a designated holding period, which allows CBP officers to conduct internal reviews if necessary. Throughout this cycle:
- ACE updates final duty totals
- The system automatically calculates interest owed to the importer
- Processing schedule: CBP processes liquidation actions Monday through Thursday only each week
Step 5: Electronic Distribution of CAPE Refunds
In the final step, once entries liquidate or reliquidate, they flow into ACE Collections. Here, the CAPE refund system:
- Groups refunds by liquidation date and Importer of Record number
- Routes funds to the designated recipient (the importer or, if you specified via CBP Form 4811, an authorized customs broker)
- Issues CAPE refund payments electronically via Automated Clearing House (ACH)
Phased Implementation of the CAPE Refund System
Important: Not all entries will process immediately through the CAPE refund system. CBP is implementing CAPE in phases, with the initial phase focusing on standard, uncomplicated entries.
Phase One: CAPE Refund Processing for Standard Entries
By prioritizing straightforward entries first, CBP can return the largest volume of refund money to the market as quickly as possible. Subsequently, the agency will address complex entries in later phases of the CAPE refund process.
Excluded from Phase One of CAPE Refunds
The following entry types will notably not qualify for initial CAPE refund processing:
- Antidumping/Countervailing Duties (AD/CVD): CBP excludes entries subject to AD/CVD determinations
- Suspended/Extended Liquidation: CBP does not process entries with liquidation statuses marked as suspended, extended, or under review
- Warehouse Withdrawals: CBP leaves goods withdrawn from bonded warehouses for later phases
- Drawback Claims: CBP excludes entries associated with duty drawback claims
Prepare Now for CAPE Refund System Submission: Critical Planning Steps
While CAPE remains under development and CAPE refund submissions are not yet open, importers should begin preparing immediately. Taking action now will accelerate your refund once the CAPE refund system launches. [See also: Our guide on the Supreme Court IEEPA tariff ruling].
1. Verify ACE Portal Access for CAPE Refunds
First, the CAPE refund system requires active ACE portal credentials so you can identify impacted entries, pull necessary reports, and submit CAPE Declarations.
Action: Check your login credentials today. If your access has expired, contact CBP or your customs broker to restore it immediately. Learn more about ACE Portal requirements.
2. Identify and Segment Your IEEPA Entries for CAPE Refund Eligibility
Second, use ACE reporting tools or your customs broker’s analytics platform to locate every entry impacted by IEEPA duties. This step is essential for the CAPE refund process.
Critical: Segment your data carefully:
- Standard, simple entries (eligible for Phase One CAPE refund processing)
- Complex entries (AD/CVD, drawback-related, suspended liquidation, warehouse withdrawals)
This segmentation approach enables you to submit your clean entries immediately when Phase One of the CAPE refund system opens. Importantly, you can note which entries will require later phases and follow up on them then.
3. Verify Financial Routing Information for CAPE Refund Distribution
Finally, CBP issues CAPE refunds electronically based on ACE payment information. You must ensure accuracy:
- Confirm your ACH details: Verify that your Automated Clearing House banking information is correct and current in ACE now
- Review CBP Form 4811 designations: If you’ve designated a customs broker to receive CAPE refund payments on your behalf, confirm that the Form 4811 is active and up to date
Why CAPE Refund System Preparation Matters Now
By organizing your entry data and verifying your financial details now, you eliminate friction from the CAPE refund process. When Phase One of the CAPE refund system opens, you’ll be ready to submit immediately—allowing your refund to move through the system without delays. Essentially, preparation today directly determines refund speed tomorrow.
