Customs Fraud Cases and Settlements: The Same Schemes Across Different Businesses

Customs fraud cases expose the gap between what a business sells and what it tells Customs. Welded outlets become couplings. Quartz becomes marble. Aluminum parts become finished goods, the factory moves on paper, or the invoice loses part of the price. If you know the product, the supplier or the payment, you may recognize the scheme before anyone outside the business knows which declaration to question.

The scale changed when Perfectus Aluminum agreed to a $549.5 million settlement on May 12, 2026. That superseded the $54.4 million Ceratizit USA resolution that the Justice Department’s fact sheet accompanying its January 16, 2026 annual results had called the largest customs fraud resolution under the False Claims Act.

Tariff Evasion Cases Start With the Importer’s Declaration

Tariff evasion cases begin with information the importer supplies itself: product description, tariff classification, origin, value and duty owed. U.S. Customs and Border Protection recorded 50.1 million entry summaries in fiscal 2025, a system built around those declarations. A customs broker may file them, but the importer of record remains responsible. The broker’s instructions and the information supplied by the business matter as much as the entry summary, CBP Form 7501, that reaches Customs.

Importers deposit estimated duties before the final bill is fixed, so an understated declaration gives the business a price advantage while the goods are being sold. In the Sigma case, the court held that the duty obligation arose when the goods arrived. Waiting for the final calculation did not erase it.

What Happens If You Use the Wrong HTS Code?

A false HTS code that hides duties can lead to a False Claims Act judgment. Sigma Corporation sold welded outlets while declaring them as steel couplings, and a jury found it violated the law. The court’s account put the customs forms beside Sigma’s own catalog and website, which called the products welded outlets. The goods did not change between the sales desk and the port. Their description did.

Island Industries, its competitor, brought the qui tam case. Repeated undercutting by Chinese imports led an Island salesperson to investigate. He found the antidumping order within a day. Sigma had made no inquiry into whether it owed antidumping duties on its welded outlets. The government declined to join, and Island took the case to trial. The jury found more than $8 million in unpaid duties before the law tripled the damages.

Allied Stone allegedly turned quartz into marble or crystallized glass on its import paperwork. Its August 19, 2025 settlement was $12.4 million. The allegations reached a countertop supplier’s dealings with manufacturers and third parties serving as importers of record. These customs misclassification cases connect the product the customer buys to the description that determines the duty.

The paper Customs Tariff Classification and the Use of Assistive Technologies, published in World Customs Journal in 2024, reports shortcuts described by practitioners, including copying the supplier’s invoice code or reusing the code from the last shipment. It identifies a commercial incentive behind one of them:

The paper also describes companies tying tariff codes to product numbers in their own systems. That connection gives the sales catalog, purchasing record and customs declaration a common product to follow.

DOJ Tariff Fraud Cases Follow the Factory Behind the Shipment

DOJ tariff fraud cases involving Ceratizit and Evolutions Flooring show why both the country of origin and the manufacturer’s identity matter. The shipping route, the origin printed on the goods and the origin that determines the duty each answer a different question.

Ceratizit distributes tungsten carbide, a hard, wear-resistant material used in cutting tools. In its December 18, 2025 announcement, the Justice Department alleged that Chinese-made products traveled through Taiwan and entered as Taiwanese to avoid tariffs on Chinese goods. The settlement also covered allegedly incorrect tariff codes and unpaid duties on merchandise lacking country-of-origin markings. A whistleblower brought the case and was awarded approximately $9.75 million from the settlement proceeds.

Evolutions settled for $8.1 million on March 25, 2025 over allegedly false manufacturer and origin information for Chinese multilayered wood flooring. Its amount reflected ability to pay. The flooring carried antidumping duties, countervailing duties and additional tariffs on Chinese goods. Customs visited factories in Thailand, had flooring specialists review shipments and examined import records. A company brought the whistleblower case.

The country on a shipping document cannot tell that whole story. Production records show what a factory actually did to the goods.

The Customs Invoice Can Leave Part of the Price Out

Global Plastics and Marco Polo International agreed to a $6.8 million settlement on July 23, 2025 covering allegedly incorrect origin and value declarations for Chinese plastic resin. The comparison runs from what the importer paid to what it declared.

Barco Uniforms sells apparel to restaurants and health care providers. The Justice Department’s April 18, 2025 complaint announcement alleged a double-invoicing scheme in which false entry summaries understated the value of imported garments. A former director of product commercialization brought the whistleblower case, and the government joined it.

Customs undervaluation can also concern payments outside the invoice. A buyer may pay separately for packing, molds or royalties that belong in the declared value. The accounting records can explain a payment the customs invoice leaves out.

What Is an Assist in Customs?

An assist is something the buyer supplies free or at reduced cost for making the imported goods, such as components, tools or molds. Its value belongs in the customs value even though the factory did not charge for it. That puts a tooling purchase or production agreement beside the merchandise invoice in an undervaluation inquiry.

Does Customs Value Include Freight?

Separately identified international freight, insurance and associated shipping charges are excluded from the price used for U.S. customs valuation. The customs valuation law makes the distinction. The underlying freight bill matters when a declared deduction reduces the value on which duty is paid.

Aluminum Parts Become Finished Goods on Paper

The alleged aluminum extrusion schemes at Perfectus and Grosfillex asked Customs to accept a finished product the underlying business did not support. Their civil settlements concerned the antidumping and countervailing duties on Chinese aluminum extrusions.

The Justice Department alleged that Perfectus imported more than 2.2 million extrusions spot-welded into supposed pallets and claimed they were finished merchandise outside the duty orders. It said there were no customers for the pallets, and none was ever sold. Whistleblowers brought the civil cases.

Grosfillex, a patio furniture company, allegedly packaged some aluminum parts as sham furniture kits. Its whistleblower complaint quotes an engineering manager discussing how the imports should look:

The complaint alleges that imported barstool bases and backs would usually be separated and paired with different parts. That is why the intended use inside the factory matters: the purported kit and the product actually assembled can tell different stories. Grosfillex’s July 24, 2025 settlement was $4.9 million. An employee brought the case, and the settlement provided a 20% whistleblower share.

What the Company Did After the Warning Matters

Leaving known customs errors uncorrected was a separate allegation in the Grosfillex settlement. The Justice Department said the company learned that earlier forms falsely excluded certain aluminum parts from the duties and failed to correct them. That allegation concerned different parts from those packaged as sham kits.

In Barco, the government alleged that underpayments continued after a third-party auditor identified risks and recommended rechecking the duty calculations behind supplier prices. An insider may know who received that advice and what happened to the affected entries afterward.

CBP Duty Evasion Cases Under the Customs Penalty Law

CBP duty evasion cases also reach court as government claims for unpaid duties and customs fraud penalties. The product mismatch can look familiar while the court decides a different kind of case.

NYWL Enterprises imported coaxial cable under incorrect tariff lines, including duty-free welding wire. The court’s April 16, 2021 decision described product labels, boxes and invoices showing the cable. It also traced earlier imports through Win Long, where correct tariff classifications had been crossed out and replaced with the classification for welding wire. After the company failed to defend the case, the court entered judgment for fraud.

Six Star’s wire hangers entered as clothing racks, and its plastic carrier bags entered without their antidumping duties too. The court entered judgment for negligence on January 18, 2019 after Six Star failed to defend the case, awarding $529,684 in unpaid duty and penalties. The same mismatch between goods and descriptions appears in cases with different findings and bills.

Wanxiang settled allegations that it misclassified Chinese automotive components, including wheel hub assemblies containing tapered roller bearings. The Justice Department reported collecting more than $53 million on December 18, 2025, including all the lost revenue it sought and more than $30 million in civil penalties.

Univar USA settled for $62.5 million on April 9, 2019 over allegedly routing Chinese saccharin through Taiwan to evade antidumping duties. Rupari declared Chinese crawfish tail meat as Thai, and the court entered a fraud judgment on March 9, 2018. This false-origin pattern reaches across products as different as sweetener and seafood.

Duty Evasion Lawsuits Put Business Knowledge to Work

Duty evasion lawsuits connect what someone in the business knows to what the importer told Customs and the duty it left unpaid. Sigma’s verdict, Barco’s complaint and the settlements show different outcomes from following that connection.

Who Can File a Qui Tam Lawsuit?

An employee or a competitor can bring a customs qui tam case. Sigma’s competitor knew the product and the market. The employees behind Barco and Grosfillex knew the business from inside. A supply-chain insider may hold the supplier instructions, invoice history or factory correspondence that explains how the declaration came to be made.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. The reward follows the recovery specified for that case: Perfectus’s announced share was about 18% of settlement proceeds returned to Customs.

What Evidence Is Needed for Qui Tam?

The useful evidence connects particular imports to the actual product, payment, factory and decisions inside the company. A catalog gives the commercial description. Supplier invoices and payment records show the price. Production records show what happened at the factory. Earlier warnings can show what the company knew when it kept using the declaration.

The industry creates those records at different times. Before ocean cargo is loaded, the importer supplies manufacturer and origin information in a security filing. The carrier separately files a manifest. We work with you to connect those records to the declaration and the business behind it.

Mirror Analysis and Revenue Fraud, published by the World Customs Organization in 2015, sets out a way to compare a country’s imports with its trading partners’ reported exports. Gaps in quantity, weight or value help identify flows for investigation. The paper describes vehicles declared as spare parts: a shortfall under one product code can appear beside excess imports under a cheaper code.

The losses fall on the competitor that paid its duties, the American industries the orders were meant to protect and taxpayers. The dishonest saving happens while the goods are being sold. The settlement comes afterward.
