The Department of Justice has secured what it describes as the largest trade-related False Claims Act settlement in history, and the case is a flashing warning light for any government contractor whose supply chain reaches across the Pacific. As detailed in the Sidley False Claims Act Blog, Perfectus Aluminum Inc., Perfectus Aluminum Acquisitions LLC, and four affiliated warehousing companies agreed to pay $549.5 million to resolve allegations that they evaded antidumping and countervailing duties on Chinese aluminum. DOJ announced the resolution on May 12, 2026.

The defendants here are importers, not federal prime contractors. But the mechanics of the case, the enforcement architecture behind it, and the qui tam dynamic that drove it all map directly onto the customs exposure that contractors carry whenever they bring foreign components into the United States. The settlement signals that the government now treats duty evasion as a fraud problem worth pursuing at headline-grabbing scale.

The Scheme: Pallets That Were Not Pallets

According to the government's allegations, from 2011 to 2014 the defendants imported more than 2.2 million aluminum extrusions from China. Rather than declare them as the extrusions they were, the defendants spot-welded the pieces together so they resembled "pallets" and declared them as finished merchandise. That distinction mattered enormously: finished pallets fell outside the 2011 antidumping and countervailing duty orders covering aluminum extrusions, while the underlying extrusions did not.

The vehicle for the evasion was CBP Form 7501, the entry summary that importers file with U.S. Customs and Border Protection to declare merchandise and calculate duties owed. By falsely characterizing the welded assemblies as exempt finished goods on that form, the defendants allegedly avoided the AD/CVD duties that would otherwise have applied. As the Morgan Lewis analysis explains, misstatements on the Form 7501 are the precise conduct that converts an ordinary customs underpayment into a False Claims Act exposure under a reverse false claims theory, where a defendant is accused of improperly avoiding an obligation to pay the government.

This was not the government's first encounter with Perfectus. A related criminal case, United States v. Perfectus Aluminum Inc. in the Central District of California, produced an August 2021 jury conviction and an order of roughly $1.8 billion in restitution to CBP. The Ninth Circuit affirmed that result in July 2024. The civil FCA settlement now layers a $549.5 million recovery on top of that criminal history, underscoring that the government is willing to pursue both criminal and civil tracks against the same duty-evasion conduct. For contractors, the lesson is that a customs misclassification is not a one-time accounting error to be quietly corrected; it can generate parallel liability that compounds over years.

The Enforcement Architecture Behind the Record

What makes this case instructive for contractors is who built it. The resolution was coordinated by the DOJ Civil Division, the DOJ Trade Fraud Task Force, U.S. Customs and Border Protection, and the Department of Homeland Security. The Trade Fraud Task Force is the operational expression of a clear policy choice: tariff and duty evasion is now a priority fraud-enforcement target, pursued with the same interagency muscle the government brings to healthcare and procurement fraud.

Equally important is how the case originated. It was not a government-initiated audit but a set of qui tam whistleblower suits. The relators, who included officers of a Perfectus competitor along with an aluminum extruders trade group, are slated to receive 17.5 percent of the recovery, roughly $96 million. Three separate qui tam cases were consolidated in December 2025 before the settlement was reached. The competitor-as-relator dynamic is the part contractors should sit up and notice: the people most motivated to report your customs practices are the firms bidding against you, and the statute pays them handsomely to do it.

The size of the relators' share, nearly $100 million, is itself a deterrence message. It tells the market that the financial incentive to surface duty-evasion schemes is enormous, and that trade groups and rival companies are willing to act as private enforcers when they believe a competitor is undercutting them through illegal duty avoidance.

What It Means for Contractors

Government contractors do not have to be importers of record to be exposed. Many primes and subcontractors source components, subassemblies, raw metals, and electronics from suppliers who import from China and other AD/CVD-covered origins. If those goods are misclassified or duties are evaded somewhere upstream, and the contractor benefits from the resulting cost advantage or makes representations about country of origin and compliance, the False Claims Act can reach the contractor. The reverse false claims theory used against Perfectus, avoiding an obligation to pay duties owed to CBP, applies to anyone in the chain who participates in or knowingly benefits from the evasion.

The qui tam competitor-relator dynamic should reshape how contractors think about compliance risk. A $96 million relator award demonstrates that rivals and industry groups have every reason to scrutinize a competitor's pricing and sourcing and to file suit when the numbers look too good to be honest. In tightly contested federal procurements, where margins and bid pricing are visible and disputed, an unusually low component cost can become the seed of a whistleblower complaint. The Trade Fraud Task Force then provides the coordinated CBP, DHS, and DOJ Civil Division firepower to turn that complaint into a record-setting recovery.

The practical takeaway is supply-chain due diligence. Contractors should map where imported components enter their products, confirm that suppliers are correctly classifying merchandise and paying applicable AD/CVD duties, and document that diligence. Where pricing from an overseas-sourced supplier looks materially below market, that gap may reflect evaded duties rather than genuine efficiency, and a contractor that accepts it without inquiry inherits the risk. Country-of-origin certifications, Form 7501 accuracy in the upstream chain, and contractual compliance representations from suppliers are no longer back-office paperwork; they are FCA risk controls. With the largest-ever trade-related FCA settlement now on the books and a dedicated task force actively hunting duty evasion, the cost of ignoring customs compliance in the supply chain has never been higher.
