On December 19, 2025, the Department of Justice (DOJ) announced a $54.4 million settlement with Ceratizit USA, LLC, a distributor of tungsten carbide products, resolving allegations that the company violated the False Claims Act (FCA) by evading customs duties on products imported from China. This settlement is believed to be the largest ever customs-related FCA resolution, and this high-water mark underscores the government’s heightened enforcement focus on tariff evasion.

On August 29, 2025, the Department of Justice (DOJ) and the Department of Homeland Security (DHS) launched a cross-agency Trade Fraud Task Force to expand efforts to target importers and other parties committing trade-related fraud. As stated in a press release issued on August 29, the Task Force will augment the existing coordination mechanisms within the DOJ and DHS, for instance through partnerships with CBP and Homeland Security Investigations, to “aggressively” take enforcement measures against parties that commit tariff evasion or attempt to smuggle prohibited goods into the U.S.

On June 23, 2025, the Ninth Circuit issued a long-awaited decision in Island Industries Inc. v. Sigma Corp. affirming a $26M False Claims Act (“FCA”) judgment against the defendant importer.  Sigma had appealed the judgment after a jury found the company violated the FCA by failing to pay customs duties owed to U.S. Customs and Border Protection (“CBP”).  The Ninth Circuit’s decision addresses an important jurisdictional issue and illustrates the significant financial exposure importers can face under the FCA at a time of increased tariffs and enforcement by the government.  

In recent years, there has been a steady rise in the number of lawsuits brought under the False Claims Act (FCA) alleging that importers have concealed obligations to pay duties to U.S. Customs and Border Protection. The increase in the number of qui tam suits filed by whistleblowers, combined with the current administration’s protectionist policies, suggests that U.S. importers could face increased FCA risks for years to come.
