The U.S. Supreme Court has rejected certain tariffs imposed under the International Emergency Economic Powers Act (IEEPA), creating a path for businesses to potentially reclaim billions of dollars. However, the exact process and timeline for these refunds remain unclear, leaving companies in a state of anticipation and facing numerous challenges in recovering their paid tariff costs. The decision has opened the door for claims, but legal experts and economists suggest the path forward will likely involve lengthy legal proceedings.

Key Points
The Supreme Court ruled certain IEEPA tariffs illegal.
Businesses that paid these tariffs may be eligible for refunds.
The process for obtaining refunds is currently unclear and is expected to be complex.
Legal battles over refunds could extend for years.
Insurers may delay refunds as they assess their own exposure.
Context of the Ruling and Refund Potential
The Supreme Court's decision impacts tariffs imposed by the Trump administration under the International Emergency Economic Powers Act (IEEPA). These tariffs, previously the subject of legal challenges, have now been invalidated by the nation's highest court. This ruling opens a window for companies that paid these specific tariffs to seek reimbursement. The total value of potential refunds is estimated to be in the hundreds of billions of dollars, according to trade attorneys.

Tariff Eligibility: Refunds are specifically for tariffs applied under the IEEPA. Businesses that did not directly pay these tariffs are not eligible.
Legal Basis: The Supreme Court's decision effectively removes a significant legal barrier that prevented claims for refunds on these tariffs.
Timeline for Claims: Under U.S. trade law, importers have a two-year window to file lawsuits for refunds.
Challenges in Securing Refunds
Despite the Supreme Court's ruling, obtaining these refunds presents considerable obstacles for businesses. The lack of a clear procedural roadmap from the court means that companies must navigate a complex legal and administrative landscape.

Court Processes: The Court of International Trade is the usual venue for such refund claims. However, both the court and the U.S. government will need time to establish procedures for managing a potentially massive volume of refund requests.
Insurer Involvement: Companies often paid tariffs through bonds or collateral managed by insurers. These insurers may be hesitant to issue refunds quickly, as they need to ensure they are not liable for the tariff payments themselves. This could lead to delays in recovering funds paid as collateral.
Legal Fees: For smaller importers, the cost of legal and court fees associated with pursuing a refund claim could outweigh the potential amount recovered. This may lead some to abandon their claims, even if eligible.
Legal Avenues and Future Proceedings
The Supreme Court's decision did not provide explicit instructions on how refunds should be processed. This has led to considerable ambiguity.

Dissenting Opinions: While the majority opinion focused on the legality of the tariffs, Justice Brett Kavanaugh noted in his dissenting opinion the lack of clear next steps for refunds, highlighting the uncertainty.
Ongoing Litigation: Importers had previously filed suits at the U.S. Court of International Trade to pause the final tariff payment determination while the Supreme Court case was pending. The denial of these requests suggests that a significant period of litigation may still lie ahead.
Expert Estimates: Trade attorneys and economists predict that the process of resolving these refund claims could take as long as five years, underscoring the protracted nature of the recovery effort.
The Role of Customs Brokers
For many small businesses engaged in international trade, customs brokers are expected to play a crucial role in the refund process. These intermediaries are often the first point of contact for businesses and will likely be at the forefront of assisting them in identifying eligible tariffs and navigating the refund application procedures.
Expert Perspectives
Trade attorneys and economists offer varying insights into the potential outcomes for companies seeking refunds. While some acknowledge the opportunity for recovery, others emphasize the significant hurdles that remain.

Monitoring Developments: Closely following rulings and guidance from the Court of International Trade and U.S. Customs and Border Protection will be critical.
