A recent procedural ruling from the U.S. Court of International Trade could significantly raise the stakes in litigation over federal tariff collections. The court reportedly allowed importers seeking refunds of tariffs imposed under the International Emergency Economic Powers Act (IEEPA) to proceed on a class basis, a development that may transform what might otherwise be a set of individual refund disputes into a much broader challenge with greater financial and strategic impact.

In practical terms, class treatment matters because tariff cases often involve many importers paying similar duties under the same government action.

The Justice Department has announced a $549.5 million settlement with Perfectus Aluminum Inc. and related companies to resolve allegations that they evaded customs duties on imported aluminum products by submitting false entry paperwork. The recovery stands out both for its size and for what it signals about the government’s continued willingness to use the False Claims Act as a tool in trade and customs enforcement.

According to the government, the misconduct centered on false statements and documentation affecting duties owed on aluminum imports.
