Trade Fraud Whistleblowers: Why Importers Face FCA Risk

A whistleblower filed a lawsuit against an importer in 2022. The case stayed sealed for years. In December 2025, the importer paid $54.4 million to settle. The whistleblower walked away with $9.75 million. This is not a rare event anymore. The U.S. Department of Justice is using the False Claims Act to turn customs violations into federal fraud cases. Anyone with evidence can file. And anyone who files can get paid.

What Is the False Claims Act and How Does It Apply to Trade?

The False Claims Act (FCA) is a federal law that punishes fraud against the U.S. government. It applies to any false statement that causes the government to lose money. In trade, that means customs declarations. If you misclassify a product, fake the country of origin, or undervalue goods to reduce duties, those false statements on your entry documents can trigger FCA liability.

The law imposes treble damages — three times the amount the government lost. On top of that, each false claim carries a civil penalty of $11,665 to $23,331 per violation (31 U.S.C. § 3729). For importers filing hundreds of entries per year, the exposure adds up fast.

Until recently, most customs enforcement stayed within CBP's administrative penalty system under 19 U.S.C. § 1592. That system caps penalties based on the value of the goods. The FCA has no such cap. According to the DOJ, customs fraud is now a civil fraud risk with unlimited exposure.

How Does a Qui Tam Whistleblower Case Work?

A qui tam case starts when a private person files a lawsuit on behalf of the U.S. government. The case is filed "under seal," which means it stays secret. The defendant does not know about it. Only the DOJ and the court see the complaint. The government then investigates — sometimes for years — before deciding whether to join the case.

If the government intervenes, federal prosecutors take over. If the government declines, the whistleblower can still pursue the case independently. Either way, the whistleblower keeps a share of whatever the government recovers.

This secrecy is what makes qui tam cases dangerous for importers. According to the DOJ's Trade Fraud Task Force, cases can remain under seal for multiple years while the government builds its evidence. By the time you learn about the lawsuit, the investigation may already be complete.

How Much Can a Trade Fraud Whistleblower Earn?

Under 31 U.S.C. § 3730, a successful whistleblower receives 15% to 30% of the total recovery. The exact percentage depends on two factors: whether the government intervenes, and how much the whistleblower contributed to the case.

If the government intervenes, the whistleblower's share is 15% to 25%. If the government does not intervene and the whistleblower proceeds alone, the share rises to 25% to 30%.

In December 2025, the DOJ announced the largest customs-related FCA settlement in history. Ceratizit USA LLC, a North Carolina-based importer, paid $54.4 million to resolve allegations of origin fraud and tariff misclassification (DOJ, 2025). The whistleblower, Mark Stover, received approximately $9.75 million of the settlement proceeds.

The conduct in question stretched back to 2015 — a full decade before the settlement. The FCA's statute of limitations allows cases to reach back up to 10 years. Past compliance failures do not expire quickly.

Who Can File a Trade Fraud Whistleblower Case?

Almost anyone. The FCA does not limit qui tam filings to employees. Competitors, suppliers, freight forwarders, customs brokers, former employees, and even people who participated in the fraud can file. You do not need to be a U.S. citizen. You do not need direct access to the company's records. You need evidence that false claims were submitted to the government.

According to the National Whistleblower Center, competing companies are among the most common qui tam filers in trade fraud cases. A competitor who loses market share to a company evading duties has both the motive and the knowledge to build a case.

The DOJ's Corporate Whistleblower Awards Pilot Program, expanded in May 2025, now covers trade, customs, and tariff violations. This gives whistleblowers an additional channel beyond traditional qui tam lawsuits.

What Types of Customs Violations Trigger FCA Liability?

The DOJ has pursued FCA cases involving several categories of customs fraud. Based on settlements and enforcement actions in 2025, the most common violations include:

Origin fraud (transshipment). Routing goods through a third country to disguise the true origin. In the Ceratizit case, Chinese-made tungsten carbide was shipped through Taiwan and declared as Taiwanese to avoid Section 301 tariffs.

Tariff misclassification. Using incorrect HTS codes to reduce duty rates. Ceratizit also used wrong HTS codes to bring the general duty rate to zero on certain products.

Undervaluation. Declaring a lower value on entry documents to reduce the duty base. CBP's AI targeting tools now flag value anomalies across shipments.

Marking violations. Failing to mark goods with the correct country of origin before distributing them in the U.S. market.

According to CBP, the agency had 1,200 active investigations into revenue-focused trade violations through its e-Allegations portal as of late 2025. These investigations feed directly into DOJ's enforcement pipeline.

Why Is DOJ Increasing Trade Fraud Enforcement in 2026?

On August 29, 2025, the DOJ and the Department of Homeland Security launched a cross-agency Trade Fraud Task Force. The Task Force brings together DOJ's Civil and Criminal Divisions, CBP, and Homeland Security Investigations. Its stated goal: to aggressively pursue anyone who evades tariffs or customs duties.

The Task Force delivered results fast. On a single day in December 2025, DOJ announced three enforcement actions totaling more than $100 million in settlements and penalties. CBP issued a transshipment alert on the same day, signaling expanded enforcement through supply chain audits and Enforce and Protect Act investigations.

According to trade law firm Akin Gump, DOJ treats customs fraud as a top-two enforcement priority in its white-collar crime agenda. The Task Force uses the FCA, criminal prosecution under Title 18, and administrative penalties in parallel. CBP is also investing in AI-powered supply chain mapping to detect transshipment and undervaluation patterns automatically.

For importers and exporters, the message is clear. Document accuracy is no longer just a compliance best practice. It is a legal shield against whistleblower lawsuits, treble damages, and criminal prosecution.

Frequently Asked Questions

Can a competitor really file a whistleblower case against me?

Yes. Under the False Claims Act, any person or entity with evidence of fraud against the government can file a qui tam lawsuit. Competing companies are common filers in trade fraud cases because they have industry knowledge and financial motivation.

What is the statute of limitations for trade fraud under the FCA?

The FCA allows cases to be filed up to six years after the violation, or three years after the government learns of the fraud, whichever is later. The absolute limit is 10 years from the date of the violation.

Does voluntary disclosure reduce FCA penalties?

It can. DOJ's Corporate Enforcement and Voluntary Self-Disclosure Policy provides for reduced penalties — and in some cases, declination of criminal prosecution — when companies voluntarily disclose violations, cooperate fully, and implement remediation measures. In the Ceratizit case, a related company that self-disclosed received a criminal declination.

How do I protect my company from a trade fraud whistleblower case?

Start with accurate documentation. Verify your HTS classifications, country of origin determinations, and declared values against source records. Conduct periodic internal audits. Establish internal reporting channels so employees raise concerns internally before going to outside counsel.
