Customs Fraud FAQ: When the Paperwork Tells a Different Story

Customs fraud means knowingly avoiding duties owed on imported goods. The supplier gets paid the full price, but Customs sees a smaller invoice. The catalog names the product, but the entry calls it something cheaper to import. If you know where those accounts part company, you may know the fact that makes a whistleblower case.

What Are the Red Flags for Tariff Evasion?

Red flags for tariff evasion include import records that contradict each other: the supplier’s payment against the declared value, the catalog against the customs description, or the claimed origin against factory records. An audit warning followed by the same underpayment adds another question: who knew, and what did they do next?

In the Barco Uniforms apparel case, the Justice Department alleged double invoicing and continued underpayment after an outside auditor recommended checking the duty calculations. Its complaint puts the price difference plainly:

But, the duty rate was applied to the falsified, lower price (“Custom FOB”), not the real price.

United States’ complaint, United States ex rel. Lee v. Barco Uniforms Inc., et al.

The allegation concerns the number the rate was applied to. Getting the rate right would still leave Customs short if the price underneath it was false.

What Evidence Is Needed to Prove Fraud?

Useful customs fraud evidence connects the shipment, the duty and the people who knew. Entry summaries, invoices, payments, product specifications, factory records and communications become stronger when they describe the same goods.

The trade creates those records in different places. For ocean cargo, the Importer Security Filing records the manufacturer or supplier, origin and other shipment details before arrival. The entry summary carries the declared value, classification and duty rate. A supplier payment ledger exceeding the customs invoice, or a manufacturer in the security filing that conflicts with the origin story on the entry, gives us something specific to investigate.

Customs relies primarily on importers to report the duties they owe. An insider may know the payment or production facts missing from that account.

Accounts payable may hold the real price. Sourcing may know the factory. A broker may have the instruction to use another description. We connect those accounts with you, including the warning, the response and any later entries or corrections.

Can Public Trade Data Help a Competitor?

Yes. Shipping data, catalogs and market knowledge can identify the shipment or product that deserves a closer look. For a competitor without internal invoices, that can be the beginning of a case.

The World Bank’s 2016 paper The Use of Detailed Statistical Data in Customs Reform, studying Madagascar, found that comparing exporting and importing countries’ records with patterns in customs declarations helped identify high-risk operators. Comparing declared unit values with international market prices highlighted probable fertilizer misclassification. The useful connection is between the trade pattern and the product someone actually knows.

Who Can Be a Whistleblower?

Employees, competitors, suppliers, brokers and industry groups can bring useful knowledge of customs fraud. The person who sees the false declaration may work somewhere different from the person who knows what the factory made or received in payment.

A competitor brought the case against Sigma Corporation. Sigma sold welded outlets and declared steel couplings. Its catalog and customs forms gave different names to the same goods. The competitor took the case to trial, and a jury found Sigma liable under the False Claims Act. An honest importer had been competing against a price that left out the duty.

A former employee started the Barco case, and the government joined it. Your own part in the conduct, if any, belongs in our conversation about the case and the team it needs.

Can a Whistleblower Bring a False Claims Act Case Over Unpaid Tariffs?

Yes. A False Claims Act qui tam case can recover knowingly avoided customs duties. A reverse false claim means keeping money owed to the government. The importer need never ask the government for a payment.

The court’s Sigma opinion explains why the duty obligation exists when goods arrive, even before the final amount is fixed. What the company knew matters too: actual knowledge, deliberate ignorance and reckless disregard can support the case. An instruction to lower the invoice, an ignored audit or a decision to leave known errors uncorrected can connect the unpaid money to that knowledge.

What Is the Penalty for Customs Fraud?

A False Claims Act violation can bring triple damages and civil penalties. In the Sigma case, the jury found more than $8 million in damages before the law tripled them. The customs penalty system has its own rules, which we assess against the conduct involved.

How Much Is a Whistleblower Claim Worth?

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. Your potential customs whistleblower reward rests on the recovery and your share of it.

The Justice Department announced approximately $9.75 million for the whistleblower in the Ceratizit USA case. That case concerned alleged false origin declarations, misclassification and unpaid marking duties on tungsten carbide products. We assess the duties and evidence behind your case rather than apply an average payout to it.

What Is Included in Customs Value?

Customs value starts with the price actually paid or payable and can include payments outside the supplier’s invoice. Under customs valuation law, assists, qualifying royalties and money returned to the seller can add to the price used for duty.

Customs undervaluation can therefore run through several accounts. The supplier’s ledger, a payment made on its behalf or a debt offset can explain why the customs invoice understates what the seller received. A supplier’s claim that everyone understates value leads us back to the transactions and instructions it actually knows.

What Is an Assist in Customs?

An assist is something the buyer supplies free or at reduced cost for making the imported goods. Tooling, molds, components and qualifying design work performed outside the United States can add value that never appears on the factory invoice.

We examine assists, royalties and seller proceeds alongside the purchase. A royalty required as a condition of sale can belong in customs value. With related-party customs valuation, the company’s internal price and later price adjustments need to be connected to what it declared.

Does Customs Value Include Freight?

International freight and insurance are excluded from the price used for customs value. An inflated freight charge can shrink the declared value, so the freight bill and the amount deducted belong beside the supplier payment when we examine suspected undervaluation.

How Do You Prove Country of Origin?

Production records establish where the goods were made and what processing occurred before export. Routing goods through another country does not change where they were made. In Ceratizit’s case, the Justice Department alleged that Chinese tungsten carbide passed through Taiwan and was declared Taiwanese to avoid duties.

Marking origin, free-trade preferences and trade-remedy origin can involve different rules. We match the factory, components and processing behind the certificate to the rule the importer claimed. A certificate unsupported by production records leaves the central question unanswered.

How Do US Customs Verify Country of Origin?

Customs can examine factories, shipments, import records and witness accounts. In the Evolutions Flooring case, the Justice Department alleged false manufacturer and origin information on Chinese multilayered wood flooring. Investigators visited factories in Thailand and had product experts review shipments. The inquiry reached the place the product was supposedly made.

What Happens If You Use the Wrong HTS Code?

Knowingly using a false Harmonized Tariff Schedule classification to avoid duty can support a False Claims Act case. The product itself may contradict the description used to obtain the lower rate.

In Ceratizit’s case, the government alleged that the company misclassified tungsten carbide products to pay lower duties. The product description and the tariff code need to tell the same story.

What Are Antidumping and Countervailing Duties?

Antidumping duties address imports sold below fair value, while countervailing duties offset foreign subsidies. Both protect domestic producers. Coverage turns on the written order and the actual goods, with the manufacturer or exporter and entry period affecting the rate.

A wrong manufacturer can therefore mean the wrong AD/CVD rate. We compare the actual producer with the producer claimed on the entry and the duty order covering that product. In Evolutions’ case, the alleged false manufacturer and origin information affected imports subject to antidumping, countervailing and Section 301 duties. A false declaration can reach several parts of the same duty bill.

How Can a False Product Description Evade a Duty Order?

Calling components finished goods can conceal that a duty order covers them. The alleged pallet and furniture-kit schemes show how a product description can change the duty bill.

Perfectus Aluminum allegedly spot-welded aluminum extrusions into apparent pallets and claimed they were finished goods outside the duty orders. The Justice Department said the supposed pallet business had no customers and sold no pallets.

Grosfillex allegedly packaged aluminum furniture parts as sham kits to avoid duties. The whistleblower’s complaint quotes an engineering manager’s instruction:

We are also trying to avoid to show anything that could indicate we are buying separate components. The less info is visible, the best [sic] it is. We are buying kits: not seats and backs.

Engineering manager’s words quoted in the whistleblower’s complaint, United States of America ex rel. Edward Wisner v. Grosfillex, Inc.

What the company planned to assemble and sell gives the declared kit something concrete to answer to.

Who Can Be Responsible Beyond the Importer of Record?

The companies that direct or supply false declarations can matter alongside the named importer. In its settlement announcement, the Justice Department alleged that Allied Stone misrepresented Chinese quartz as marble or crystallized glass and failed to ensure that manufacturers and third-party importers declared and paid the duties. The goods reached Allied Stone’s warehouses or jobsites.

Who Pays Anti-Dumping Duty?

The importer of record owes the duty, even when a broker handles the entry. Paying the broker does not discharge that debt if the money never reaches Customs. The initial antidumping deposit is an estimate, and the final assessment may be different.

Who Is the Importer of Record for a DDP Shipment?

The entry identifies the importer of record. A delivered-duty-paid promise puts costs on the seller under the purchase contract, but the filed importer identity still needs to be checked. Customs cases have involved a buyer’s importer number used without its knowledge.

For suspected misuse of an importer number, we examine the contract, power of attorney, filing instructions and duty payments with you. The seller’s promise and the money Customs received are separate parts of the account.

What Happens After Entry, Release and Liquidation?

Release lets the goods move. Liquidation fixes the duty amount. The duty obligation starts when the goods arrive, and liquidation does not erase duties avoided through false declarations. The Sigma opinion makes that point directly.

What Happens When an Importer Reports Its Own Customs Errors?

Self-reporting can still end in a False Claims Act settlement. Global Plastics and Marco Polo International disclosed incorrect origin and value declarations for Chinese resin and agreed to pay $6.8 million.

Grosfillex shows the other decision: the Justice Department alleged that it left earlier false forms uncorrected after learning they were wrong. What happened after discovery can be the part an insider knows best.

Are Section 301 Tariffs Still in Effect?

Yes. Section 301 duties remain part of the duty calculation. A tariff action addressing foreign forced-labor practices took effect July 24, 2026. We match the product, origin and entry date to the applicable action and exclusions. The country a shipment passed through does not by itself answer the origin question.

What Is the $800 Rule?

It was the commercial de minimis exemption for low-value shipments. The all-country suspension took effect August 29, 2025. A Customs rule published June 24, 2026 indefinitely suspended the exemption for nonpostal shipments, with international postal shipments handled separately. We assess suspected order-splitting or false-value schemes against the rules for those shipments’ entry dates.

Are Section 301 Tariffs Eligible for Drawback?

Yes. Customs confirms that Section 301 duties are eligible for drawback. A knowingly false drawback claim seeks money back from the government. The export and refund records then become part of the evidence we examine.

What Does the Trade Fraud Task Force Do?

The Justice Department and Department of Homeland Security coordinate trade-fraud enforcement through the Trade Fraud Task Force. The effort brings Customs and Justice Department resources to cases involving unpaid tariffs and duties.
