On April 14, 2026, US Customs and Border Protection opened the CAPE portal for IEEPA tariff refund claims. The portal is the federal mechanism for administering refunds to importers who paid IEEPA tariffs that the Supreme Court determined in early 2026 had been unlawfully collected. The total refundable amount across all eligible importers is approximately $166 billion. The structural problem is that the average refund claim requires customs counsel, archived entry summaries, supplier-side documentation, and a four-step procedural compliance that most small importers are not staffed to execute. Roughly 97% of US importers are small businesses. A meaningfully smaller share has access to customs counsel.

For merchants in district corridors who paid IEEPA tariffs in 2024 and 2025, the refund eligibility is real as a matter of law and substantially harder to access as a matter of practice. The piece is the merchant-side guide to the CAPE process: what is recoverable, what the documentation requirements actually are, the four-step compliance task list, the cost-benefit math for engaging counsel versus filing pro se, and the structural critique that the refund mechanism as designed favors importers with established trade compliance infrastructure.

What the SCOTUS decision did

The Supreme Court's February 2026 decision on the IEEPA tariff legality question (Plat Street covered the decision in PC·RW·1·2·2 platcard in Issue 2) determined that certain IEEPA-imposed tariffs had been unlawfully collected. The decision created legal entitlement to refund for importers who paid the unlawfully collected tariffs. The decision did not create a refund delivery mechanism. The mechanism was developed by CBP in the months following the decision and went live with the CAPE portal opening on April 14.

The mechanism's structure follows standard CBP refund administration practice. Importers who believe they have refund eligibility file claims through the CAPE portal, providing documentation that supports the eligibility determination. CBP reviews the claims, validates the documentation, and processes refunds for claims that meet the procedural requirements. The procedural requirements are non-trivial. They presume that the importer maintains entry summaries, supplier invoices, classification documentation, and payment records in a form that supports backward reconciliation against the IEEPA tariff payments at issue.

Why most small importers cannot execute

For small importers, the procedural barrier is meaningful at multiple points in the refund claim process.

First, the entry summary documentation. Customs entry summaries are the formal records of merchandise entering the United States, with classifications, valuations, and tariff calculations. Importers are required to maintain entry summaries for five years under standard CBP recordkeeping rules. In practice, small importers who use customs brokers often rely on the broker to maintain the documentation, and the importer's own files may not contain the entry summaries in the form needed for refund claims. Reconstructing the documentation from broker records is often possible but requires broker engagement and time.

Second, the supplier-side documentation. Refund claims require documentation tying the imported merchandise to the IEEPA tariff classifications at issue. The documentation typically includes supplier invoices, country-of-origin certifications, and classification-supporting product specifications. Small importers who source from multiple suppliers often have the documentation distributed across supplier relationships, with varying degrees of organization. Assembling the documentation across suppliers requires sustained outreach and time.

Third, the procedural compliance steps. The CAPE portal's claim process involves four sequential steps with specific deadlines and content requirements. Each step requires the importer to assemble specific documentation, format it to CBP's specifications, and submit it within the prescribed window. Errors in formatting, omissions in documentation, or missed deadlines result in claim denial or delay. Small importers without customs counsel typically lack the procedural familiarity to execute the steps efficiently.

Fourth, the dispute resolution capacity. When CBP denies a claim or requests additional documentation, the importer must respond on a defined timeline. Importers without customs counsel often lack the capacity to respond effectively, particularly when the denial cites technical procedural defects rather than substantive eligibility issues. The dispute resolution capacity is the difference between an eligible claim that gets paid and an eligible claim that gets denied.

The cost-benefit math

For a small importer evaluating whether to engage customs counsel for a refund claim, the cost-benefit math depends on the refund amount at stake, the documentation burden the importer can execute internally, and the importer's tolerance for procedural risk.

Customs counsel typically charges between $250 and $600 per hour for refund claim work, with engagement scope ranging from limited assistance to full claim management. A typical full-claim engagement for a small importer with one to three years of IEEPA tariff payments might run between $4,000 and $15,000 in counsel fees, depending on documentation availability and claim complexity. The fee is separate from any contingent fee arrangement, which some customs counsel will accept on larger refund claims.

For an importer whose IEEPA tariff payments at issue are below approximately $20,000 to $25,000, the counsel cost is a meaningful share of the refund amount. The importer's rational economic decision is often to file pro se, accepting the higher procedural risk. For an importer whose payments are above approximately $50,000, the counsel cost is a smaller share of the refund amount and the procedural risk reduction typically justifies the engagement. Between $25,000 and $50,000, the decision is a judgment call that depends on the importer's internal documentation discipline and tolerance for delay.

For corridor merchants whose IEEPA tariff exposure was distributed across many small entries, the cumulative refund eligibility may be substantial even when no single claim crosses the counsel-engagement threshold. The strategy in those cases is to consolidate claims across entries, filing a single refund claim that covers multiple entries with shared documentation. The consolidation reduces the per-claim procedural burden and improves the cost-benefit math for counsel engagement.

The four-step compliance task list

For importers proceeding with refund claims (with or without counsel), the four-step compliance task list is the operational backbone of the claim process.

Step one is documentation assembly. The importer assembles the entry summaries, supplier invoices, classification documentation, and payment records that support the refund claim. The assembly typically requires outreach to customs brokers, suppliers, and internal accounting staff. The assembly should be complete before the claim itself is initiated, because mid-claim documentation requests produce delay and procedural risk.

Step two is eligibility verification. The importer (or counsel) reviews the assembled documentation against the SCOTUS decision's eligibility scope, identifying which entries and which tariff payments are eligible for refund. The verification produces a defined refund amount that the claim will pursue. The verification should be conservative, excluding marginal eligibility cases that would create dispute risk during CBP review.

Step three is claim preparation and submission. The importer assembles the documentation and the eligibility analysis into the CAPE portal's required claim format and submits the claim. The submission process is technical and benefits from familiarity with CBP procedural requirements. First-time filers should plan for a meaningful learning curve, particularly in formatting requirements that the portal does not consistently flag in advance.

Step four is post-submission management. After submission, the importer manages CBP communications, including any requests for additional documentation, classification questions, or eligibility disputes. The post-submission management can extend over months. The importer who plans for sustained post-submission engagement produces meaningfully better outcomes than the importer who treats submission as the end of the process.

The structural critique

The refund mechanism as designed produces a predictable distributional outcome. Importers with established customs counsel relationships, sophisticated trade compliance infrastructure, and large enough refund amounts to justify counsel engagement will recover a meaningful share of the refunds they are eligible for. Small importers without those resources will recover meaningfully less, often leaving substantial eligible refunds uncollected.

The structural critique is not that the mechanism is improper. CBP's refund administration practice is consistent across categories of refund claims, and the procedural requirements reflect legitimate documentation needs. The structural critique is that the SCOTUS decision created an entitlement whose distributional effect depends on access to professional services that small importers cannot affordably engage. The result is that the population of importers most affected by the IEEPA tariffs (small importers in corridor retail, food and beverage, and general merchandise) recovers a smaller share of their refund eligibility than larger importers do.

For district managers and merchant association leaders, the structural critique suggests an opportunity. Coordinated refund claim assistance, organized at the district level, can produce economies of scale that individual small importers cannot achieve. A district that organizes a shared customs counsel engagement, pools documentation work across multiple member merchants, and centralizes the post-submission management can deliver refund recovery to merchants who would not otherwise pursue claims. The model has been used in other CBP refund contexts and is technically straightforward. The barrier is organizational rather than legal.

What merchants should be doing now

For merchants who paid IEEPA tariffs in 2024 and 2025, three operational steps follow inside the next 60 days.

First, conduct a documentation inventory. Identify the entry summaries, supplier invoices, classification documentation, and payment records that exist in the merchant's files for the relevant period. The inventory determines the feasibility of refund claims and identifies the documentation gaps that need to be addressed before claim filing.

Second, calculate the cumulative IEEPA tariff exposure across the relevant entries. The calculation produces the refund amount that potential claims could pursue. The amount determines the cost-benefit math for counsel engagement.

Third, decide whether to pursue refund claims individually, as part of a coordinated district-level effort, or not at all. The decision should be made deliberately. Merchants who default to inaction by not making the decision typically leave substantial refund eligibility uncollected.

For district managers and merchant association leaders, the operational step is to assess whether district-level refund claim coordination would benefit member merchants. The assessment requires understanding how many member merchants paid IEEPA tariffs, what their cumulative refund eligibility looks like, and whether shared counsel engagement is feasible. The assessment can be done in May and June. Districts that complete the assessment before summer can launch coordinated efforts in time to recover meaningful refunds before procedural deadlines compress the available window.
