The Emerging Wave of Tariff Refund Class Action Lawsuits Poses Significant Risks for Businesses Across Supply Chains

A complex and rapidly expanding legal challenge is gripping businesses across diverse sectors: a wave of consumer class action lawsuits alleging unjust enrichment stemming from tariffs. At the heart of these cases is a singular, overarching legal theory: companies that passed tariff costs onto consumers while simultaneously seeking and retaining government refunds for those same tariffs may be liable for unjust enrichment. This litigation targets not just direct importers but entities throughout the supply chain, from food manufacturers to logistics providers, signaling a broad exposure to risk for any business that navigated the tumultuous waters of recent trade policy.

The Core Legal Theory: Unjust Enrichment and Double Recovery

The central tenet of these lawsuits, as articulated by legal experts from firms like Foley & Lardner, is straightforward yet potent: a business cannot profit twice from the same economic event. When tariffs were imposed, many companies adjusted their pricing, incorporating "tariff surcharges" or simply raising prices to cover the additional import duties. Subsequently, legal challenges to certain tariffs created avenues for businesses to apply for and receive refunds from the government for duties already paid. The plaintiffs in these class actions contend that if a company collected the tariff cost from consumers and then received a refund from the government, it has been "unjustly enriched" by effectively recouping the cost twice.

Foley & Lardner lawyers Erik Swanholt and Kelsey Boehm emphasized the non-industry-specific nature of this legal theory: "Plaintiffs have filed class actions against companies across varying industries and points in the supply chain from food manufacturers to logistics providers. The specific allegations in each case differ, but the primary legal theory is the same: companies cannot pass tariff costs to consumers and retain government refunds for the same tariffs." This broad applicability means that any enterprise, regardless of its specific product or service, that found itself in this dual-recovery scenario could become a target.

Holland & Knight lawyers further underscored this widespread vulnerability in a legal alert, stating unequivocally that "any business that both passed tariff costs through to customers and is pursuing government refunds could become a litigation target." This warning sends a clear signal to corporate legal departments and financial officers to meticulously review their tariff-related cost recovery and refund strategies.

Background to the Tariffs: Section 301 and the Path to Refunds

To fully understand the current legal landscape, it’s essential to revisit the context of the tariffs themselves. The bulk of these lawsuits pertain to the Section 301 tariffs imposed by the United States on a vast array of goods imported from China, initiated under the Trump administration starting in 2018. These tariffs, authorized under Section 301 of the Trade Act of 1974 and often justified by the International Emergency Economic Powers Act (IEEPA), were a response to alleged unfair trade practices, intellectual property theft, and forced technology transfers by China.

The Section 301 tariffs were implemented in several tranches or "lists," escalating over time and ultimately impacting hundreds of billions of dollars worth of Chinese imports. Businesses across the U.S. supply chain, from retailers and manufacturers to component suppliers, faced significant new costs. Many responded by absorbing some of the costs, seeking alternative suppliers, or, critically, passing these costs through to consumers via price increases or specific tariff surcharges.

The opportunity for refunds arose from successful legal challenges to the tariffs, particularly at the U.S. Court of International Trade (CIT). While the Supreme Court has not issued a blanket invalidation of these tariffs, specific procedural challenges at lower courts did raise questions about the U.S. Trade Representative’s (USTR) compliance with administrative procedures when modifying or extending certain tariff lists. For instance, in September 2021, the CIT ruled in Huaiyang County Fuan Foodstuff Co. v. United States that the USTR had failed to adequately explain its decision to impose "List 3" and "List 4A" tariffs, remanding the matter back to the agency for further justification. While this did not outright "invalidate" the tariffs in the sense of making them immediately unlawful for all purposes retroactively, it created a legal pathway for importers to argue for refunds on duties paid, particularly for those lists. The anticipation and eventual realization of these refund opportunities, combined with the earlier passing of costs to consumers, established the foundation for the current wave of unjust enrichment claims.

The Chronology of Tariff Impact and Litigation:

• 2018-2019: U.S. imposes Section 301 tariffs on Chinese goods in multiple tranches. Businesses begin adjusting pricing, often passing costs to consumers.
• 2020-2021: Legal challenges to the tariffs mount, primarily at the Court of International Trade, questioning the USTR’s authority and procedural compliance.
• Late 2021-Early 2022: Key CIT rulings, such as Huaiyang County Fuan Foodstuff Co. v. United States, create pathways for businesses to seek refunds on certain tariff payments.
• 2022-Present: Companies begin receiving tariff refunds from the government. Simultaneously, consumer class action lawsuits emerge, alleging unjust enrichment against companies that both passed on costs and received refunds.
• Ongoing: Litigation intensifies, with companies like Nintendo moving to compel arbitration and legal experts advising on defense strategies.

Businesses Scramble for Defenses: Contractual Agreements and Legality at Time of Charge

With lawsuits still in their nascent stages, no court has yet issued a definitive ruling on the core legal theories, leaving businesses and their legal counsel to develop robust defense strategies. Holland & Knight lawyers have highlighted several potential avenues for defense.

One primary defense revolves around the existence of an express contract between the parties. In many jurisdictions, the doctrine of unjust enrichment is deemed inapplicable when an explicit contract governs the relationship. "In many jurisdictions, unjust enrichment is unavailable where an express contract governs the parties’ relationship," noted Holland & Knight partners Ashley Akers and Austin Rainwater. This implies that if a company’s terms of service or purchase agreements clearly stipulated the possibility of tariff-related surcharges or price adjustments, and consumers agreed to these terms, the claim of unjust enrichment might be significantly weakened. The success of this defense will likely hinge on the clarity, conspicuousness, and enforceability of such contractual provisions.

Another significant defense challenges the premise of retroactive unlawfulness. Businesses can argue "that the challenged charges were imposed while the IEEPA tariffs remained legally effective and enforceable." According to this view, the subsequent legal developments or rulings that allowed for refunds do not automatically render charges collected before those decisions unlawful or create a retroactive obligation to refund amounts previously paid. The argument posits that at the time of the transaction, the tariffs were valid government-imposed duties, and passing them on was a legitimate business practice. The legal complexities here involve distinguishing between a tariff being procedurally flawed (leading to a refund opportunity) and being fundamentally unlawful ab initio.

Nintendo’s Arbitration Push: A Key Litigious Tactic

As the legal battles unfold, companies are employing various procedural tactics to manage and potentially mitigate their exposure. A prominent strategy involves compelling arbitration, a move already initiated by Nintendo. Arbitration clauses, often buried in a company’s terms and conditions, require disputes to be resolved through private arbitration rather than through public court proceedings or class actions.

Nintendo, facing a lawsuit from Hoffert, filed a motion to compel arbitration, citing evidence that the plaintiff had "affirmatively accepted contractual agreements with Nintendo at least twice." This proactive stance by a major corporation like Nintendo highlights the industry’s intent to enforce these pre-dispute resolution mechanisms. In another related action, Nintendo indicated in its motion to dismiss that it "expressly reserves the right to move to compel Mr. Sharan’s claims to arbitration if discovery reveals his claims are arbitrable."

The success of such motions is critical for businesses. Arbitration generally offers several advantages: it is typically faster, less expensive, and, most importantly for defendants, it often precludes class action lawsuits. If courts uphold arbitration clauses, it would fragment the class actions into individual arbitrations, significantly reducing the aggregate liability and logistical burden for companies. However, the enforceability of arbitration clauses, particularly in consumer contexts, can vary by jurisdiction and the specifics of how the agreement was presented and accepted.

Breach of Contract Claims: A Parallel Legal Threat

Beyond unjust enrichment, some tariff-related lawsuits, particularly within the shipping and logistics sectors, are also advancing claims of breach of contract. "This is the principal claim in many shipping and logistics cases," states the Holland & Knight alert. Plaintiffs in these cases allege that "tariff-related surcharges were not authorized under applicable shipping agreements, terms of service or tariff schedules."

This legal theory is distinct from unjust enrichment. It focuses not on whether a company received a double benefit, but whether it had the contractual right to impose the surcharge in the first place. If a shipping agreement, for example, did not explicitly permit the addition of a "tariff surcharge" or a mechanism for adjusting prices based on new duties, then imposing such a charge could be construed as a breach of the agreed-upon terms. This underscores the importance for businesses, especially those in service industries with complex contractual relationships, to review and update their terms and conditions to explicitly address unforeseen costs like tariffs.

Broader Impact and Implications for Businesses

The implications of this wave of litigation are far-reaching, extending beyond immediate financial exposure to encompass reputational damage and a re-evaluation of business practices.

• Financial Liability: The sheer volume of tariffs collected and subsequently refunded represents billions of dollars. If class actions are successful, the cumulative liability for businesses could be substantial, requiring significant payouts to consumers. Even if individual consumer refunds are small, the aggregate could be immense.
• Litigation Costs: Defending against multiple class action lawsuits, regardless of their outcome, incurs significant legal fees and internal resource drain.
• Reputational Risk: Allegations of "double dipping" or unjustly profiting from government refunds can severely damage a company’s public image and consumer trust, potentially leading to boycotts or diminished brand loyalty.
• Contractual Scrutiny: Businesses will face increased pressure to ensure their terms and conditions are transparent, comprehensive, and legally sound, particularly regarding pricing mechanisms and surcharges. The ambiguity surrounding "tariff surcharges" has proven to be a significant vulnerability.
• Supply Chain Management: Companies will need to meticulously track tariff costs, their pass-through to customers, and any subsequent refunds, maintaining clear documentation to defend against future claims. This requires enhanced internal accounting and legal review processes.
• Arbitration Landscape: The prevalence and enforceability of arbitration clauses will be rigorously tested. The outcomes of motions to compel arbitration will significantly shape the future of consumer class action litigation in many sectors. If arbitration is widely enforced, it may shift the battleground from federal courts to private arbitration panels, fundamentally altering the dynamics of consumer disputes.

Consumer Protection and Future Outlook

For consumers, these lawsuits represent an opportunity to potentially recoup monies they believe were unfairly collected. The success of these actions would set a precedent for greater transparency from businesses regarding how government-imposed costs are handled and how subsequent refunds are managed. It underscores the power of collective action in addressing perceived corporate overreach.

From a regulatory and policy perspective, this litigation highlights the complex interplay between trade policy, corporate pricing strategies, and consumer protection. While the tariffs themselves were a government measure, the handling of their costs and refunds by private entities has now become a central point of legal contention.

As these cases progress, the legal community will closely watch for judicial rulings on the core theories of unjust enrichment, the validity of contractual defenses, and the enforceability of arbitration clauses. The ultimate outcomes will not only determine significant financial liabilities for businesses but also reshape the landscape of consumer litigation in an increasingly globalized and tariff-impacted economy. Businesses are advised to proactively assess their exposure, consult with legal counsel, and prepare robust defense strategies to navigate this challenging legal environment.
