Consumers have hauled Nike into federal court in Portland, accusing the company of quietly hanging on to tariff-related price hikes even after the U.S. Supreme Court voided the emergency tariffs that drove those increases in the first place.
In a proposed class-action suit, the plaintiffs say Nike bumped prices on some footwear by $5 to $10 and raised certain apparel by $2 to $10 while the company was paying roughly $1 billion in import duties. Now that those duties may be refunded, the suit asks a judge to make sure Nike does not keep both the consumer-paid increases and any federal refund, casting the dispute as a basic fairness fight over who should keep money collected under an unlawful government policy. Lawyers for the consumers say the case could force retailers and brands across the country to decide whether any tariff refunds belong with shoppers or on corporate balance sheets.
What the complaint says
The complaint, filed May 8, quotes the plaintiffs as saying, "Nike has made no legally binding commitment to return tariff-related overcharges to the consumers who actually paid them," and warns the company "stands to recover the same tariff payments twice" if the court does not step in. The filing seeks class certification along with an order barring Nike from retaining federal refund money that the company could seek through the government portal.
As reported by Reuters, the suit was brought in U.S. District Court in Portland and asks the court to act before federal refund checks start flowing.
How refunds are being processed
While the lawsuit gets underway, the federal refund machinery is already spinning up. U.S. Customs and Border Protection has created a process for importers to reclaim duties that courts have since ruled unlawful.
On April 20, CBP launched the CAPE (Consolidated Administration and Processing of Entries) functionality inside the ACE portal, giving importers or the customs broker who filed an entry a way to upload consolidated CSV "CAPE Declarations" to request refunds. Phase 1 is limited to certain unliquidated and recent entries while CBP works through more complex cases and data validations. Covington & Burling has laid out the launch details and filing requirements for importers and brokers.
Why plaintiffs say Nike shouldn't keep refunds
The plaintiffs argue that Nike did not simply absorb the tariffs as a cost of doing business but instead folded them into end consumer prices. The complaint points to $5 to $10 price hikes on some shoes and $2 to $10 increases on certain apparel as evidence of that pass-through.
Nike has acknowledged that it paid roughly $1 billion in tariffs and told investors in late March that tariffs remained a material headwind to gross margin through the quarter ending in August 2026. According to the suit, that combination of admitted tariff payments plus higher retail prices sits at the core of the consumers' unjust-enrichment and restitution claims.
Reuters has reported the complaint's central allegations, including the warning that Nike could benefit twice: once from higher prices paid at the register and again from federal refunds.
Legal questions ahead
The case plugs into the broader legal fallout from the Supreme Court’s February ruling that the International Emergency Economic Powers Act (IEEPA) does not authorize presidential tariffs. That decision cleared the way for refund claims but left a big unanswered question: who ultimately gets the money.
The high court’s opinion in Learning Resources, Inc. v. Trump supplies the constitutional and statutory backdrop for the refund fight. Trade-law analysts say consumer plaintiffs are likely to lean on unjust-enrichment theories and state consumer-protection statutes, while companies will argue they had no binding duty to return anything until a government refund was actually paid.
For those tracking the legal underpinnings, the opinion text is available through the Supreme Court archive at LII, and deeper analysis appears from DLA Piper.
A broader wave of suits and administrative work
Nike’s lawsuit is one piece of a much larger national puzzle. It sits alongside consumer claims against other big sellers, and plaintiffs have targeted companies including Costco and EssilorLuxottica over the same alleged problem of tariff-related overcharges and potential double recoveries.
Those cases arrive on the heels of court filings and agency work suggesting the total refund pool could reach into the hundreds of billions of dollars. Court documents and reporting place the exposure at roughly $166 billion in duties paid by more than 330,000 importers, creating what amounts to a nationwide accounting headache for retailers, carriers and brokers as CAPE processing ramps up.
Some carriers have already said they plan to pass any recoveries back to the original payors, while many brands have yet to spell out how they will handle refunds if and when they arrive. Coverage of the broader wave of litigation and the sheer scale of possible refunds appears in outlets such as Fox Business and The Guardian.
For now, the Portland case is at an early stage. Plaintiffs will push for class certification and may ask for preliminary relief to block any government refund money from being disbursed to, or used by, Nike until the court decides who owns it. Expect months of motion practice ahead as importers, carriers and retailers try to reconcile CAPE filings, liquidation timelines and competing claims over who really bore the cost of the now-invalidated tariffs.
