WASHINGTON D.C. – United States Customs and Border Protection (CBP) is in the process of establishing a system intended to return duties paid on certain tariffs, a move that could bypass the need for importers to engage in legal action. Officials stated in a court filing that they aim to have this refund process operational within 45 days. This development follows a recent Supreme Court decision that invalidated several tariffs previously imposed under the Trump administration.

"The agency's computer system is not equipped to immediately process the crush of refunds, but that it's working on a streamlined process that would not require importers to file individual lawsuits."
The CBP's declaration to the U.S. Court of International Trade indicates that the agency's existing infrastructure is not prepared for the anticipated volume of refund requests. Consequently, they are developing a more direct method. While the timeline for processing these refunds remains unstated, the CBP has signaled an inability to meet an earlier court order demanding immediate compliance. The absence of automatic refunds means importers must take formal steps to reclaim overpaid duties, potentially involving filings like Post Summary Corrections (PSCs) for unliquidated entries or Protests for liquidated entries, provided they are within the stipulated protest window.

The tariffs in question are primarily those related to national security and emergency trade actions. Executive Order 14289, signed in April, specifically prohibits the cumulative application of certain tariffs. Importers seeking refunds are advised to review entries made on or after March 4, 2025, for overlapping tariff applications. This includes tariffs related to Section 232 auto and auto parts, as well as aluminum and steel, and duties targeting illicit drug flows from Canada and Mexico under the International Emergency Economic Powers Act (IEEPA).

Refund Process Details Remain Murky
While the CBP is developing a new system, the specifics of how refunds will be calculated and distributed are not entirely clear. The court's order did not dictate a specific refund methodology, leaving some smaller importers concerned about the potential costs and time involved in navigating the process. It has been noted that the CBP is not issuing automatic refunds, and importers must validate their Harmonized Tariff Schedule (HTS) classifications and maintain records to support their claims. The scope of the Supreme Court's decision primarily affects IEEPA-based tariffs and certain Section 232 tariffs, with other duties, such as Section 301 tariffs on China, remaining in effect.

Legal Landscape and Importer Options
The legal aftermath of the Supreme Court's tariff decision has been unfolding. Previously, importers had options that included awaiting the Supreme Court's ruling and subsequent implementation guidance from the Court of International Trade (CIT), or filing Protests and PSCs. The CIT's authority to order refunds has been confirmed. However, the effectiveness of these avenues and the possibility of late participation hinge on the specifics of the Supreme Court's ruling and the CIT's subsequent framework for implementation. Some importers were previously advised to monitor developments and assess their participation once clearer guidance emerged from the CIT.
