Companies that collected tariffs passed along to consumers are now facing class action lawsuits based on a straightforward legal theory: they will receive refunds from the government while keeping the higher prices they already charged customers—a form of “double recovery” that plaintiffs argue is unfair and potentially illegal. Following the U.S. Supreme Court’s February 20, 2026 ruling that tariffs imposed under the International Emergency Economic Powers Act (IEEPA) exceeded presidential authority, federal law requires the government to refund the $133.5 billion in tariff duties that were collected through December 14, 2025. However, companies like FedEx, Costco, and UPS that passed those tariff costs to their customers—or increased prices under the cover of tariff pressures—now face the uncomfortable position of potentially collecting government refunds while customers demand the prices be lowered or refunds be issued directly to consumers.
This legal exposure emerged almost immediately after the Supreme Court decision. Between late February and March 2026, at least 17 lawsuits have been filed, with 11 of those targeting FedEx alone. The cases allege that major retailers and logistics companies will achieve an unfair windfall if they simply pocket government refunds without passing the money back to the people and businesses that originally bore the cost of the tariffs. This article explains why companies are being sued, what the lawsuits claim, what major corporations have said about handling refunds, and what risks remain as the government attempts to process an unprecedented volume of refund claims.

Why Are Companies Facing Tariff Refund Class Action Lawsuits?
The core legal complaint is straightforward. When tariffs were in effect, companies like shipping and logistics providers, retailers, and manufacturers paid the duties to U.S. Customs and Border Protection (CBP). Rather than absorb those costs themselves, most businesses passed them along to their customers through higher prices, surcharges, or cost adjustments—the normal business practice.
Costco, for example, was specifically accused in lawsuits of “wrongfully increasing prices to recoup the economic burden of tariff-related charges.” Now that a court has ruled those tariffs were unlawful, the government must refund the money—but if companies simply keep the refunds while maintaining the prices customers already paid, they will have collected payment twice for the same tariff cost. Class action lawyers have identified this as a consumer injury. They argue that customers in the United States paid inflated prices for shipped goods, retail products, and services because companies built tariff costs into their pricing. When those tariffs are refunded to the company, and the company keeps the refund without lowering prices or issuing credits to customers, the company has effectively been made whole twice—once by the consumer and once by the government. The legal frameworks being cited include state consumer protection laws and unjust enrichment doctrines, which prohibit parties from profiting unfairly from breaches of law.
The “Double Recovery” Allegation and Consumer Claims
The term “double recovery” appears in nearly every lawsuit filed so far and represents the central claim. Plaintiffs’ attorneys allege that companies will obtain a windfall by receiving full refunds from the government while retaining the higher prices or surcharges already paid by consumers and businesses. This differs from a situation where a company absorbed tariff costs itself and simply gets a refund—in those cases, there would be only one recovery. But if the company passed the tariff cost to customers and then receives a government refund, the company ends up compensated for an expense it never actually bore. The lawsuit targets include FedEx (which paid approximately $1 billion in tariffs), Costco, UPS, Oakley, and Fabletics, among others.
However, the strength of these lawsuits depends on whether plaintiffs can prove that companies actually passed tariff costs to individual consumers. For FedEx and UPS, much of the tariff burden was borne by shipping customers—small businesses, e-commerce sellers, and individual retailers who use those services. For Costco, the claim is that price increases to members reflected the tariff cost increase. For Oakley and other direct-to-consumer brands, the allegation is that consumer prices rose in line with tariff pressures. If a company can show it absorbed tariff costs itself and is simply receiving the government refund it is entitled to, the “double recovery” claim becomes weaker. This is one reason why company communications about their refund intent matters so much in defending these suits.
How Much Money Are We Talking About?
The tariff collection numbers are enormous, making the potential refunds and litigation stakes extraordinarily high. The IEEPA duties collected totaled $133.5 billion through December 14, 2025, and the broader tariff collection efforts across all authorities reached approximately $180 billion total. That scale explains why plaintiffs’ firms moved so quickly after the Supreme Court decision. The potential refunds represent real money, and the companies at the center of supply chains and consumer retail have significant exposure.
FedEx’s $1 billion estimated tariff burden represents just the tariffs it paid to CBP; the broader amounts passed to consumers or recouped through pricing are likely higher. Costco’s membership base of over 65 million households provides a large potential class of consumers for any lawsuit settlement. The rapid filing of multiple lawsuits—at least four different lawsuits filed by five different plaintiffs’ firms between February 26 and March 16, 2026 alone—reflects confidence that these cases have economic substance and potential class damages in the hundreds of millions to billions of dollars. These are not boutique legal claims; they are being pursued aggressively by some of the nation’s largest class action law firms. For consumers, this means there is a real possibility of recovery if they were customers of these companies during the tariff period.
What Companies Are Pledging to Do with Refunds
Rather than fighting the concept of passing refunds along to consumers, several major companies have publicly committed to returning the money—though their exact mechanisms and timelines vary. FedEx made the most explicit commitment, pledging that “if refunds are issued to FedEx, we will issue refunds to the shippers and consumers who originally bore those charges.” UPS similarly stated it would “support our customers in obtaining IEEPA tariff refunds due from the government.” Costco CEO went on record on the company’s March 5, 2026 earnings call, committing to “find the best way to return this value to our members through lower prices and better values,” though he did not specify exactly when or how. These public commitments are significant because they reduce litigation risk if the companies actually follow through.
However, the difference between them illustrates a key tension: FedEx is committing to issue refunds to “shippers and consumers who originally bore those charges,” which could mean trying to trace tariff costs through supply chains and issue credits or refunds to specific customers. Costco is committing to return value “through lower prices and better values,” which is vague—lower prices could be interpreted as a general benefit to all future members, not a specific refund or credit to people who paid the higher tariff-adjusted prices. UPS’s commitment to “support our customers” in obtaining refunds from the government is the most passive, essentially offering assistance in the refund claim process rather than pledging company refunds. The gap between these promises will likely matter in settlement negotiations and, if settlements are reached, in determining who gets paid and how much.
Government Refund Processing Delays and Their Legal Impact
A major complication is that the government itself has not yet begun issuing refunds at scale. Customs and Border Protection chief Brandon Lord stated on March 6, 2026 that the agency was “not able to comply” with refund demands due to unprecedented volume overwhelming the agency’s technology infrastructure. CBP was working toward launching an online refund system expected to be operational within 45 days of that March 6 statement, placing the earliest operational date around mid-April 2026. As of March 19, 2026, the four system components required for processing were between 45% and 80% functional, meaning the refund effort was still weeks away from full deployment.
This government processing delay creates legal pressure for companies to be proactive. If customers cannot readily obtain government refunds through CBP and the companies have not yet issued their own refunds, the appearance of “keeping the tariff windfall” grows stronger. Companies may feel pressure to issue refunds or credits to customers ahead of government refunds becoming available, simply to avoid the narrative that they are waiting out government delays while consumers are left waiting. Additionally, if a company receives a government refund before its customers have received refunds or price reductions from the company, it strengthens the “double recovery” argument in pending lawsuits. Law firms filing these suits will certainly cite any gap between government refund processing and company refunds as evidence of unfair retention.
Companies’ Disclosure Obligations and Litigation Risks
Beyond the lawsuits themselves, major law firms—Ballard Spahr, Arnold & Porter, Covington & Burling, Troutman Pepper, and Morgan Lewis—have issued advisories warning companies of serious disclosure and litigation risks. These firms have flagged that companies face obligations to disclose material information to investors, customers, and stakeholders about tariff refund obligations and potential liability. If a company does not adequately disclose the risk of having to refund tariffs or the likelihood of class action litigation, it may face additional shareholder derivative claims or regulatory inquiries from the SEC.
Additionally, public statements by company leaders—like Costco’s CEO commitment to return value to members—can be used against the company in litigation if the company later takes a narrow interpretation of what that promise entails. Companies are essentially walking a tightrope between making reassuring public statements to avoid outrage and customer defection, while also protecting themselves legally by avoiding promises that could be construed as contractual obligations to refund specific amounts to specific people. This tension explains why some companies have made explicit refund pledges (FedEx) while others have been vaguer (Costco, UPS).
What Happens Next in the Tariff Refund Landscape
The immediate next phase is the April 2026 launch of CBP’s refund system and the flow of government refunds to companies and importers. Once companies begin receiving refunds, the legal pressure to pass them along will intensify. Plaintiffs’ lawyers will monitor how quickly and comprehensively companies issue refunds or credits to consumers, and any significant delays will be highlighted in the litigation and public discourse.
Companies that move quickly to issue refunds may reduce litigation exposure; companies that move slowly will face heightened class action pressure. Beyond the immediate refund issuance, broader questions remain unsettled. Will some companies settle these lawsuits to avoid the cost and publicity of extended litigation? Will settlements involve direct refunds to identified consumers, across-the-board price reductions, or credits toward future purchases? How will courts handle claims involving millions of retail customers where individual harm is diffuse? These issues will likely define the tariff refund litigation landscape for the next 12 to 24 months and could result in settlements affecting how major retailers, logistics providers, and manufacturers handle compliance with tariff refunds.
Frequently Asked Questions
Did all companies definitely pass tariff costs to consumers?
No. Some companies may have absorbed tariff costs themselves through lower profit margins rather than raising prices. However, lawsuits specifically target companies where plaintiffs can allege that prices rose in line with tariff costs or where surcharges were explicitly tariff-related. Companies that absorbed costs themselves are less vulnerable to these lawsuits.
What is the difference between a company refund and a class action settlement?
If a company voluntarily issues refunds (like FedEx says it will), customers may receive money directly without needing to join a lawsuit. If a company is sued and settles, the settlement will set terms for how money is distributed to class members. Some customers may receive more in a settlement than in a voluntary company refund, depending on the settlement terms.
How do I know if I’m eligible to claim a refund?
Eligibility depends on the specific company and lawsuit. Generally, if you purchased from or shipped through the company during the tariff period (roughly 2025 to early 2026) and paid prices you believed included tariff costs, you may be eligible. Check class action registries and company websites for specific information as lawsuits and settlements develop.
Can I file my own lawsuit or do I have to join a class action?
You can theoretically file your own lawsuit, but class actions are more practical for consumers with diffuse, smaller individual claims. Joining an existing class action is usually the path of least resistance and often results in faster recovery.
Why is the government taking so long to issue refunds?
CBP stated in March 2026 that the volume of refund claims is unprecedented and the agency’s technology systems were overwhelmed. The agency is building a new online system expected to be operational by mid-April 2026. The delay is partly why companies are under legal pressure to issue their own refunds to consumers first.
If a company issued a voluntary refund, does that end the class action lawsuit?
Not automatically. A class action lawsuit alleges the company wrongfully retained refunds and harmed consumers. A voluntary refund issued after a lawsuit is filed may reduce damages but does not necessarily eliminate the lawsuit unless the company reaches a formal settlement agreement with the class.
