Tariff Enforcement at the Forefront: Importer Agrees to Pay $549.5 million in Largest-Ever Trade-Related False Claims Act Settlement

On May 12, 2026, the Department of Justice (“DOJ”) announced a $549.5 million settlement with Perfectus Aluminum Acquisitions LLC and four affiliated companies to resolve allegations that they violated the False Claims Act (“FCA”) by evading customs duties. This settlement is the largest trade-related settlement under the FCA.

The action was initiated by qui tam cases brought by individuals who worked for U.S.-based competitors and the Aluminum Extrusion Counsel and ultimately coordinated through the DOJ’s Trade Fraud Task Force, which involved cooperation between DOJ and the Department of Homeland Security. This case highlights the increasing use of the FCA to hold importers liable for the underpayment of customs duties, the Administration’s commitment to enforcing U.S. customs laws, and the potential for competitors and former employees to harness the FCA to motivate federal investigations into allegations of trade fraud.

This post examines the settlement and discusses its implications for importers, manufacturers, and other companies facing customs and trade enforcement risk.
