The Costco CPG Brand IEEPA Tariff Refund Strategy 2026 Guide: How to Claim Your Share of $175 Billion in Duty Refunds Before the Window Closes
The Costco CPG brand IEEPA tariff refund strategy 2026 opportunity is one of the most commercially significant and most time-sensitive financial recovery opportunities available to CPG brands that imported goods into the United States between February 2025 and February 2026.
The legal and commercial background: in February 2025, the Trump administration imposed tariffs on a broad range of imports under the International Emergency Economic Powers Act (IEEPA) — a legal authority that has never previously been used to impose broad-based tariffs. In December 2025, Costco joined several other major companies in suing the Trump administration over the IEEPA tariffs. In February 2026, a federal judge ordered U.S.
Customs and Border Protection to begin issuing refunds to affected importers after finding the IEEPA tariff authority legally problematic under the framework established in prior case law.
The financial scale of what this legal development means for CPG brands: it is estimated that up to $175 billion in potential refunds on IEEPA duties collected between February 2025 and February 2026 are due. Whom those refunds flow to — the importer of record, the manufacturer, the retailer that absorbed tariff surcharges, or the consumer whose prices reflected them — is a question that CBP's refund process is still establishing as of mid-2026.
For CPG brands that paid IEEPA duties on imported ingredients, packaging components, or finished goods during the covered period, the refund opportunity is real and potentially significant — but it is a first-wave opportunity. CBP is developing the refund process, and brands that prepare their documentation now will be positioned to file in the first wave of claimants rather than waiting for the process to be fully established and competing in a later, potentially more contested filing environment.
The IEEPA Tariff Landscape: What Was Collected and What Is Refundable
The February 2025 to February 2026 IEEPA Duty Period
The IEEPA tariffs that are the subject of the refund action were imposed beginning in February 2025 and ran through February 2026 — when the Section 122 replacement tariff structure took effect, replacing the IEEPA authority with a different legal basis.
The IEEPA tariffs' specific commercial impact on CPG brands: the tariffs applied to a broad range of imports based on country of origin rather than product category — meaning the CPG brand that imported ingredients, packaging, or finished goods from tariff-affected countries during the covered period paid IEEPA duties on those imports.
The tariff rates that applied during the IEEPA period varied by country and product category, but for CPG brands with significant import volumes from China, Mexico, Canada, and other affected countries, the annual duty exposure during the 12-month IEEPA period was potentially significant.
What the Refund Covers
The IEEPA refund covers the specific duty amounts paid on imports that were subject to the IEEPA authority — distinct from Section 232 tariffs on steel and aluminum (which were imposed under separate legal authority and are not subject to the IEEPA refund), Section 301 tariffs on China (which were also imposed under separate authority and are not subject to the IEEPA refund), and the new Section 122 tariffs that replaced the IEEPA structure in February 2026 (which are in-force under a different legal authority).
The refund eligibility assessment requires the CPG brand to identify, for every import during the covered period: the specific tariff authority under which the duty was paid, the entry number at CBP, the duty amount paid, and the legal basis for refund eligibility.
This classification exercise — the HTS code audit that the tariff refund process requires — is the foundational first step that positions the brand for an accurate and defensible refund claim.
The Importer of Record Question
The most commercially consequential legal question in the IEEPA refund process: who is the importer of record, and therefore who is the party entitled to file for the refund?
The importer of record is the entity that filed the import entry with CBP at the time the goods entered the United States — the entity that was legally responsible for paying the duties at the time of importation. For CPG brands that import directly — purchasing ingredients or finished goods from international suppliers and filing their own CBP entries — the brand is the importer of record and the direct party entitled to file for refund.
For CPG brands that purchase from a domestic supplier that imports on their behalf — where the supplier is the importer of record and the CPG brand purchases at a domestic price that includes the tariff cost — the legal refund entitlement belongs to the supplier rather than the brand. The brand's commercial opportunity in this scenario is to negotiate with the supplier for a portion of the supplier's refund — arguing that the tariff cost was passed through to the brand in the purchase price and that the refund should flow back through the same commercial relationship.
The documentation requirement for the importer of record determination: the CBP entry summary documents from every import during the covered period, which identify the importer of record by name and EIN/Tax ID number.
The HTS Code Audit: The Foundation of the Refund Claim
The Four-Column Import Classification Audit
The HTS code audit that the IEEPA refund process requires is a structured classification exercise that the CPG brand must complete for every import during the February 2025 to February 2026 period.
For every significant input, packaging component, and finished goods import, identify the 10-digit HTS code, the current applicable tariff rate and its legal authority (Section 232, Section 301, Section 122, or IEEPA), the sourcing country, and the annual purchase volume in dollars.
The four-column audit format:
Import | 10-Digit HTS Code | Tariff Authority | Duty Rate | Duty Paid During IEEPA Period |
Sunflower oil (ingredient) | 1512.11.0000 | IEEPA (Ukraine origin) | Variable | $[amount] |
Aluminum packaging component | 7612.90.1020 | Section 232 (not IEEPA) | 50% | Not refundable |
China-origin finished goods | 2106.90.9998 | Section 301 (not IEEPA) | 25% | Not refundable |
IEEPA-only ingredient (other origin) | [specific HTS] | IEEPA only | [rate] | $[amount] |
The audit's commercial output: the total IEEPA-authority duty paid during the covered period — the maximum refundable amount that the brand can claim, before any adjustments for downstream absorption (where the brand passed the tariff cost through to customers rather than absorbing it internally).
The Sourcing Country Impact
The IEEPA tariffs' geographic scope was broader than the Section 301 China tariffs that preceded them — covering goods from countries not previously subject to significant Section 301 exposure. CPG brands whose ingredient sourcing included materials from Vietnam, Cambodia, India, Mexico (for goods not covered by USMCA), and other affected countries may have significant IEEPA duty exposure that the Section 301 China-focused tariff analysis missed.
The geographic audit scope: every country of origin for every import during the covered period should be assessed for IEEPA tariff exposure — not just the China-origin goods that received the most commercial attention.
The CBP Documentation Requirements: Preparing the Refund Claim File
The Foundational Documents
The CBP refund process — which as of mid-2026 is still being formally established — will require, at minimum, the following documentation for each import entry in the refund claim:
CBP Entry Summary (Form 7501): the official CBP entry document that records the entry number, the import date, the HTS classification, the country of origin, the declared value, and the duty paid. This is the primary legal document that establishes the duty payment and the authority under which it was paid.
Commercial Invoice: the supplier's commercial invoice for the imported goods, establishing the purchase price, the quantity, the country of origin, and the description of goods. The commercial invoice is the primary evidence of the goods' identity and value.
Bill of Lading or Airway Bill: the shipping document that establishes the goods' physical movement from the country of origin to the U.S. port of entry.
Certificate of Origin: the country of origin certification that establishes that the goods qualify as originating from the IEEPA-affected country under the applicable rules of origin.
Proof of Duty Payment: the CBP statement or receipt confirming that the duty was paid at the assessed rate — the financial record that establishes the refundable amount.
The Documentation Retention Requirement
CBP's standard documentation retention requirement is five years from the date of importation. For imports during the February 2025 to February 2026 IEEPA period, the five-year retention window extends to February 2030 and February 2031 respectively.
The practical implication: the CPG brand that does not currently have organized, accessible records for every import during the covered period must reconstruct those records from the available sources — the customs broker's records, the supplier's invoices, and the brand's own accounting records — before the CBP refund process is finalized and the filing window opens.
The urgency of this documentation reconstruction: CBP will likely establish a filing deadline for the IEEPA refund claims. The brand that has its documentation package assembled before the filing window opens is positioned to file in the first wave. The brand that begins the documentation reconstruction after the filing window opens may miss the first-wave deadline and compete in a later, potentially more administratively constrained filing environment.
The Customs Broker Partnership
The CPG brand that has an established relationship with a licensed customs broker has the most efficient access to the entry summary documents that the refund claim requires — because the customs broker maintains the import entry records on the brand's behalf and can retrieve specific entries by entry number, date range, or HTS classification.
For brands that do not have a customs broker relationship — including brands that used freight forwarders or third-party logistics providers who managed import entries on their behalf — reconstructing the entry documentation may require direct inquiry to CBP through the Freedom of Information Act (FOIA) request process, which adds significant time to the documentation assembly.
The recommendation for brands without established customs broker relationships: engage a licensed customs broker immediately to reconstruct the entry documentation from the covered period. The customs broker's access to the ACE (Automated Commercial Environment) database — CBP's official entry tracking system — provides the most efficient pathway to the complete entry documentation that the refund claim requires.
The Pass-Through Absorption Analysis: The Refund's Financial Allocation Question
Who Actually Absorbed the Tariff Cost
The IEEPA refund's most commercially complex legal question — and the one that the CBP refund process has not yet fully addressed as of mid-2026 — is how the refund should be allocated when the tariff cost was passed through multiple commercial relationships before reaching the end consumer.
The pass-through scenario: a CPG brand paid $200,000 in IEEPA duties on imported ingredients. To maintain the Costco wholesale price that the good value test requires, the brand absorbed $100,000 of the tariff cost internally (accepting lower channel margin) and passed through $100,000 of the tariff cost to Costco through a wholesale price increase. Costco then absorbed a portion of the pass-through internally rather than raising member prices.
In this scenario, the importer of record (the CPG brand) paid the $200,000 in duties and is the legal refund claimant for the full $200,000. But the economic argument can be made that the brand's downstream commercial relationships — Costco and ultimately the member — absorbed a portion of the economic burden of the tariff.
The practical commercial implication for CPG brands: file for the full refund as the importer of record and manage the downstream commercial relationship implications separately. The CBP refund process will not automatically redirect a portion of the refund to Costco. The commercial relationship between the brand and Costco regarding any tariff-related pricing adjustments is a separate commercial negotiation.
The Costco Pricing Adjustment Consideration
CPG brands that increased their Costco wholesale price to pass through IEEPA tariff costs should assess whether a refund creates an obligation — implicit or explicit in the commercial relationship — to reduce the wholesale price back to its pre-tariff level now that the tariff authority has been vacated.
The commercial relationship management guidance: be proactive. If the wholesale price was increased specifically due to IEEPA tariff exposure and the brand is receiving a refund of those duties, a proactive conversation with the Costco buyer — framing the situation transparently and discussing whether a wholesale price adjustment is appropriate — is the commercially sophisticated response that the buyer relationship's trust foundation rewards.
The buyer who discovers that a vendor received a tariff refund without proactively discussing its commercial implications is a buyer who will raise the question themselves — in a less commercially favorable context than the proactive conversation.
The First-Wave Filing Strategy: The Time-Sensitive Commercial Opportunity
Why First-Wave Matters
CBP is developing the IEEPA refund process, and the brand that has its documentation package assembled and its claim prepared before the formal process is finalized is positioned to file in the first wave of claimants.
The first-wave advantage is not merely administrative efficiency. In large-scale government refund programs, first-wave claimants typically receive faster processing, lower risk of documentation deficiency rejection (because the process's administrative requirements are clearest at the beginning), and less competition for administrative attention from the refund processing team.
The three-step first-wave filing preparation:
Step 1: Complete the HTS code audit — identify every IEEPA-authority duty paid during the covered period, segregated from Section 232 and Section 301 duties that are not refundable.
Step 2: Assemble the documentation package — retrieve all CBP Entry Summary documents, commercial invoices, bills of lading, and proof of duty payment for every IEEPA-refundable import.
Step 3: Engage trade counsel — work with a licensed customs attorney to review the assembled documentation for completeness, assess the importer-of-record qualification, prepare the refund claim in the format CBP's process will require, and monitor the CBP regulatory guidance for the formal filing window opening.
