IEEPA Tariff Refund Eligibility: 6 Criteria Every U.S. Importer Needs to Check

The U.S. Supreme Court’s landmark ruling on February 20, 2026, in Learning Resources, Inc. v. Trump, determined that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) were unlawful. This decision has significant implications for U.S. importers who paid duties under the IEEPA regime, prompting a comprehensive review of past payments and potential recovery options. However, determining IEEPA tariff refund eligibility is not a straightforward process. It depends heavily on multiple procedural and legal factors within the U.S. customs framework.

Why Refund Eligibility Is Not Automatic

The Supreme Court’s ruling vacated the basis for the IEEPA tariffs but did not automatically establish a refund program. While the Court of International Trade (CIT) has asserted its jurisdiction and begun to issue orders directing U.S. Customs and Border Protection (CBP) to remove these duties, the practical implementation of refunds remains in development. On March 6, 2026, CBP indicated it requires approximately 45 days to build the necessary automated functionality to process the estimated $166 billion in collected duties across more than 53 million import entries.

Recovery rights for importers are contingent upon strict adherence to U.S. customs procedures and statutory deadlines. The administrative landscape is evolving rapidly, with the CIT actively engaging with CBP on establishing a concrete mechanism for relief. This situation means that while the legal basis for the tariffs has been invalidated, the pathway to an IEEPA tariff refund is not yet fully defined and requires importers to navigate existing customs regulations and anticipate forthcoming guidance

The Six Key Criteria Importers Should Evaluate

Importers seeking to understand their potential IEEPA tariff refund eligibility must meticulously examine several critical factors for each affected entry.

1. Whether the Duties Were Actually Assessed Under IEEPA

It is paramount to confirm that the duties in question were indeed imposed under IEEPA authority. The Supreme Court ruling specifically addresses IEEPA-based tariffs, including those related to China, Canada, Mexico, and global reciprocal tariffs. Duties collected under other trade remedy statutes, such as Section 232 (e.g., steel and aluminum) or Section 301 (e.g., China-specific tariffs), are separate and unaffected by this decision. Importers must review their entry data to identify specific Harmonized Tariff Schedule of the United States (HTSUS) Chapter 99 codes associated with IEEPA tariffs to isolate eligible payments.

2. Entry Liquidation Status

The liquidation status of an import entry is a central determinant of the available refund pathway. Liquidation represents CBP's final calculation of duties, taxes, and fees owed on an entry.

• Unliquidated Entries: For entries that have not yet undergone final liquidation, adjustments are generally more accessible. These entries are still "open" in the customs system.
• Liquidated Entries: For entries that have already been liquidated, the process becomes more complex, often requiring formal protests or, in some cases, litigation in the CIT. The CIT has directed CBP to reliquidate non-final liquidated entries, but the administrative implementation remains under review. Understanding the exact liquidation date for each entry is therefore crucial.

3. Protest Deadlines

Under U.S. customs law (19 U.S.C. § 1514), importers typically have 180 days from the date of liquidation to file an administrative protest with CBP. If a protest is not filed within this window, the liquidation becomes final and conclusive, generally precluding further administrative or judicial challenge. While the CIT’s March 4 order may effectively bypass the need for protests for non-final liquidations by directing CBP to reliquidate, it is a prudent safeguard for importers with significant exposure on liquidated entries to track and, if appropriate, file protests within the statutory timeframe to preserve their rights.

4. PSC Eligibility for Unliquidated Entries

For unliquidated entries, importers may file a Post Summary Correction (PSC) to adjust the declared information, including duty amounts. A PSC can typically be filed within 300 days of the date of entry or up to 15 days prior to the scheduled liquidation date, whichever comes first. This administrative tool presents a direct method to amend entries and seek removal of IEEPA duties before they become finalized. Importers must ensure their entries remain unliquidated and meet other CBP criteria for PSC submission.

5. Importer of Record Status

The legal right to challenge duty assessments and receive refunds typically rests with the Importer of Record (IOR). The IOR is the entity legally responsible for ensuring customs compliance and for the payment of duties at the time of import. If a refund is issued by the U.S. government, it will generally be paid directly to the IOR. Importers should verify their IOR status for each entry and ensure that their Automated Commercial Environment (ACE) portal account is active and set up for Automated Clearing House (ACH) refunds. If a customs broker is authorized to receive refunds on behalf of the IOR, proper documentation (e.g., CBP Form 4811) and broker ACH enrollment are necessary.

6. Contractual Allocation of Tariff Costs

While the U.S. government will pay any determined refunds to the IOR, the ultimate economic beneficiary of these refunds may be subject to commercial agreements. Many importers passed on IEEPA tariff costs to their suppliers or downstream purchasers through contractual provisions. Importers must review their supply agreements, purchase orders, invoices, and other commercial documents to understand how tariff risk and costs were allocated. Clauses related to tariff pass-through, change-in-law, and pricing adjustments will be critical in determining who ultimately retains the refunded funds. This contractual analysis determines the true economic IEEPA tariff refund eligibility within the commercial ecosystem.

Why Entry-Level Data Matters

U.S. customs procedures, including duty assessment, collection, and potential refunds, operate at the individual entry level. Each shipment has its own unique characteristics, including classification, valuation, country of origin, and associated HTSUS codes, all of which influence its specific duty calculation and liquidation timeline. Companies that have historically tracked duties at an aggregate level will find it challenging to determine precise IEEPA tariff refund eligibility without granular detail. A thorough analysis requires access to and review of entry summaries (CBP Form 7501), commercial invoices, bills of lading, proof of duty payment, and specific liquidation dates for each affected entry. This detailed, entry-by-entry data is indispensable for identifying eligible entries, accurately quantifying potential refunds, and executing the correct procedural steps.

Preparing for an Evolving Regulatory Environment

The current environment is dynamic. CBP has outlined a proposed automated refund process, indicating it could be operational within 45 days from its March 6, 2026, statement. However, the exact parameters, required importer submissions, and timeline for this process are still being finalized. Further court decisions, including potential appeals of the CIT's orders, and subsequent administrative guidance from CBP may continue to shape how refund claims are handled. Rather than waiting for definitive instructions, importers should proactively audit their import records now. Reviewing and organizing entry-level data, understanding liquidation statuses, and identifying all IEEPA-affected entries will position importers to act swiftly and effectively once official refund mechanisms are fully established, maximizing their potential for IEEPA tariff refund eligibility.

Determining IEEPA tariff refund eligibility necessitates a meticulous and systematic review of individual customs entries, their liquidation timelines, and the procedural rights associated with each. The core step for U.S. importers today is to thoroughly understand their data and the specific status of every affected entry, rather than assuming an automatic or universally applicable refund.
