Perfectus Aluminum and Related Companies Agree to Pay More than $500 Million to Resolve Antidumping Duty Evasion Allegations
On May 12, 2026, the United States Department of Justice (DOJ) announced that Perfectus Aluminum Inc. and five related companies (collectively, the “Perfectus Companies”) had agreed to pay $549.5 million to resolve allegations that they violated the False Claims Act (FCA) by knowingly evading antidumping duties (ADDs) and countervailing duties (CVDs) on aluminum extrusions imported from China.
The core allegations against the Perfectus Companies are not new. Rather, they stem from a series of qui tam complaints that date back to 2015 and that were further developed through civil and criminal investigations and prosecutions that culminated in a guilty verdict, criminal forfeitures, and a $1.83 billion restitution award. Still, the announced settlement now stands as the largest FCA resolution ever for tariff evasion and it underscores the DOJ’s newfound focus on detecting, deterring, and punishing trade fraud.
Background
In 2011, the United States imposed ADDs and CVDs on certain Chinese extruded aluminum products. The Perfectus Companies responded to these duties by spot-welding certain aluminum products together so that they might appear to be finished products—which, if true, meant that the products would not have been subject to the ADDs and CVDs. In fact, however, the products were not finished goods at all, so the scheme allowed the importer to avoid more than $1.8 billion in ADDs and CVDs.
Beginning in 2015, three different sets of relators filed sealed complaints under the FCA. That appears to have triggered a broader investigation. In 2017 and 2018, the US Attorney’s Office for the Central District of California filed a series of civil forfeiture actions against the Southern California warehouses used by Perfectus to store the pallets and the pallets themselves, some of which had been seized by Customs and Border Protection (CBP). And then, in 2019, that same Office filed an indictment against the Perfectus Companies, its Chinese parent company, and various Chinese nationals.
Following a 2021 criminal trial, a jury found the companies guilty of one count of conspiracy, nine counts of wire fraud, and seven counts of passing false and fraudulent papers through a customhouse. Two of the companies were also found guilty of money laundering. At sentencing, the court ordered the companies to pay more than $1.8 billion in restitution, and ordered them to forfeit the warehouses and the aluminum products that were used to perpetuate the scheme.
On May 13, the DOJ announced a further civil resolution under the FCA. Specifically, the Perfectus Companies agreed to pay $549.5 million to resolve allegations that they knowingly evaded antidumping and countervailing duties owed on aluminum extrusions imported from China. The alleged civil misconduct included false statements on customs forms that misrepresented more than 2.2 million aluminum extrusions as finished merchandise not subject to duties, even though they were allegedly spot-welded together to look like pallets.
Why the FCA Action Matters
The criminal sanctions against the Perfectus Companies were already substantial, so the FCA settlement may not have a material impact on the overall penalties. But the FCA settlement is significant because it provides a window into DOJ’s evolving enforcement strategies. Not long ago, tariff or duty evasion was viewed as a pure Customs issue. But today, the DOJ is focused on trade fraud, and violations are met with multiple tools, including criminal charges, civil and criminal forfeitures, administrative claims, and FCA remedies.
1. The FCA adds treble damages and penalties to unpaid-duty risk.
The Customs laws have always provided for significant penalties for duty evasion, including up to the domestic value of the merchandise for fraud, up to the lesser of domestic value or four times lost duties for gross negligence, and up to the lesser of domestic value or two times lost duties for negligence. The FCA adds a separate remedial framework: civil penalties plus three times the government’s damages. That gives the government options in terms of how it addresses evasion efforts and the potential to maximize recoveries.
2. The FCA creates qui tam and competitor-driven enforcement risk.
The Customs laws enforced by the government through customs procedures and, if necessary, proceedings in the Court of International Trade. The FCA, by contrast, allows private persons—known as “relators”—to bring actions on behalf of the United States under the statute’s qui tam provisions. The financial incentives for relators are significant: depending on whether the government intervenes in the case, a successful relator may recover between 15% and 30% of the total settlement or judgment. In the Perfectus matter, for example, the relators who filed the initial complaints beginning in 2015 will receive 17.5% of the $549.5 million recovery. These incentive structures encourage whistleblowers to come forward with credible allegations, even if doing so carries personal or professional risk.
In the customs context, who can serve as a relator is a critical enforcement variable. Competitors, current or former employees, customs brokers, freight forwarders, logistics providers, warehouse operators, or other supply-chain participants can all become enforcement catalysts by filing qui tam suits. This is particularly significant because supply-chain actors often have direct knowledge of misclassifications, false country-of-origin statements, undervaluation schemes, or ADD/CVD evasion tactics—information that CBP may not discover through routine audits or port-of-entry inspections.
3. The FCA reduces dependence on CBP detection.
Traditional customs enforcement depends heavily on CBP review, audits, investigations, and administrative penalty processes—all of which require government resources, initiative, and prioritization. FCA qui tam enforcement fundamentally supplements that model by creating financial incentives for insiders and competitors to identify and litigate alleged duty evasion. Because relators can file under seal while DOJ investigates, companies may face exposure without any initial awareness that an investigation is underway.
The Perfectus matter illustrates how competitor or insider actions can trigger and accelerate FCA investigations. In that case, multiple qui tam complaints were filed beginning in 2015—years before criminal charges were brought. Those relator filings provided an early roadmap of the alleged scheme, identified key players and evidence, and ultimately supported both criminal prosecution and the civil FCA settlement. For companies, this timeline demonstrates that qui tam filings may precede—and shape—subsequent government enforcement, making early detection of compliance failures critical.
Bottom Line
FCA liability expands customs-fraud exposure by making customs compliance an FCA issue, not just a CBP penalty issue. The biggest expansions are treble damages, qui tam relator incentives, competitor suits, parallel DOJ enforcement, and the ability to characterize false customs entries as false records used to avoid payment obligations to the United States. For companies in the supply chain, the increased enforcement risk is clear: any actor with knowledge of noncompliance—competitors, employees, brokers, or logistics providers—may have both the information and the financial incentive to file a qui tam complaint.
The limiting principles are still important: FCA liability requires materiality and knowing conduct, and it should not convert every customs mistake into an FCA case. But where there is evidence of deliberate misclassification, false origin, undervaluation, AD/CVD evasion, or concealment after learning of an error, the reverse FCA theory materially increases both monetary exposure and the likelihood that someone other than CBP will initiate the case. Companies should treat trade compliance as an enterprise risk management priority, with robust internal controls designed to detect and address issues before relators or competitors do.
