Known Customs Errors Left Uncorrected: What Happened After the Company Knew

A knowing failure to correct a customs entry can become a False Claims Act case even if the company never submits another false document. Knowingly keeping that money can be a reverse false claim all by itself.

Failure to Correct a Customs Entry Under the False Claims Act

Grosfillex agreed to pay $4,936,732 over alleged customs duty evasion that included leaving false entry forms uncorrected after learning they were wrong. For an insider, that is the part of the story worth pursuing: who knew the duties were unpaid, and who decided to leave them that way.

What management does after finding out that it left duties unpaid matters: correct the old entries and pay, or leave the government short.

Grosfillex Allegedly Left Known False Customs Forms Uncorrected

Grosfillex, a patio furniture company importing Chinese aluminum parts, allegedly failed to correct customs forms after learning they falsely denied antidumping and countervailing duty coverage. Its settlement agreement covered entries from January 2014 through December 2021.

The Department of Justice’s announcement separates the conduct into different groups of furniture parts. Some allegedly arrived packaged as sham finished furniture kits to conceal the duty-covered aluminum. For a different group, Grosfillex allegedly learned that its earlier forms were false and left them alone. The government pursued the decision to leave those entries uncorrected alongside the false declarations themselves.

A former employee brought the qui tam case. The settlement provided for a 20% whistleblower reward from the government’s recovery. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

Global Plastics Reported Its Customs Errors and Still Faced a Bill

Global Plastics and Marco Polo International reported problems they found with their plastic resin entries and still faced a False Claims Act settlement. Their settlement agreement records a disclosure to U.S. Customs and Border Protection in May 2024 and a separate disclosure to federal prosecutors that November.

The government alleged that some Chinese resin had been declared as originating in Taiwan, Saudi Arabia or the United States. Other entries involved missing country-of-origin markings or incorrect values. The alleged shortfalls reached China tariffs, ordinary import duties and merchandise processing fees.

The government gave them FCA cooperation credit for an independent investigation, supplying facts and a damages analysis, disciplining staff and improving compliance. The civil settlement announced in July 2025 required $6,896,094.

The cooperation included preserving and disclosing facts the government did not already know. Reporting the problem did not make the bill disappear. It changed how the government treated the companies. Put that beside the failure to correct alleged at Grosfillex, and the difference is plain in what the companies did after they knew.

Barco’s Auditor Warning and the Alleged Underpayments That Followed

Barco Uniforms allegedly continued underpaying customs duties after an outside auditor advised it to check the duty calculations behind its supplier prices. Barco sells uniforms to restaurants and health care providers. The Department of Justice’s complaint announcement describes alleged apparel undervaluation through double invoicing and false entry summaries that understated the value of garments bought from foreign suppliers.

The warning concerned the calculations behind prices Barco had agreed to pay. That puts the purchasing decision and the customs declaration in the same story. A former director of product commercialization brought the whistleblower case, and the government joined it.

A compliance officer who saw customs valuation audit findings ignored may recognize the sequence. The warning and the response together can help show what the company knew or deliberately avoided finding out.

What Evidence Is Needed for Qui Tam?

The useful customs fraud evidence connects what management knew with the affected entries, its decision about correcting them and the money still unpaid. Internal reviews can show what the company learned and who received the findings. Approvals and broker instructions can show what management decided. Corrections, disclosure letters and payment records show what reached Customs and what was actually paid.

The commercial information can sit outside the broker’s file. A buyer may have paid separately for molds supplied free to a factory, or for a royalty required as a condition of the sale. Those costs can belong in the value declared to Customs. Accounts payable, tooling purchases and royalty agreements can show the amounts behind the declaration. Factory production records can connect the claimed country of origin to where the goods were actually made. An audit that brings those records together can also show when the company learned its entries were wrong.

The Importer’s Information Reaches the Broker

A customs broker whistleblower may have seen the importer supply information it already had reason to doubt. Samsung C&T America admitted that it had reason to know invoices and other documents misstated the materials and construction of imported footwear. It passed that information to its customs brokers without verifying it, knowing they would use it to prepare the entries. The resulting classifications understated duties on many shipments.

A 2011 World Customs Journal paper, Reversing the trend: low cost and low risk methods for assuring proper duty payments, described how clearing agents with incomplete product information often reuse a code from an earlier shipment. The same classification can travel from one entry to the next. In a known-error case, the instructions to the customs broker help show whether the importer passed on the correction or kept the old information moving.

The money has its own trail. Under Customs’ importer-payment rule, paying the broker leaves the importer owing the duty if the broker never pays Customs.

Purchasing Can Know What the Entry Leaves Out

High Life’s settlement admissions show how purchasing decisions can control the values reported to Customs. After Customs detained apparel shipments in December 2015, High Life changed from buying at prices that included freight and duties to taking responsibility for importing the garments itself. Some orders were already in production at agreed prices.

High Life then worked backward from those prices to calculate the factory prices it wanted to declare to Customs. Its employees directed revisions to supplier spreadsheets, and the resulting declared values produced lower duty payments. The purchase orders, agreed prices and revised spreadsheets connected the commercial decision to the customs figure.

A commercial buyer can also receive the warning while another company handles the imports. Garment wholesaler Notations admitted failing to act on multiple signs that its importing business partners were undervaluing goods and underpaying duties. Knowledge can sit with the customer as well as the company named on the entry.

New Filing Instructions Do Not Pay Old Customs Duties

International Vitamin Corporation admitted correcting classifications for future imports while leaving earlier underpayments unresolved. The company imported vitamins and nutritional supplements from China. In its settlement admissions, it acknowledged using duty-free classifications for 32 products that should have carried duties as food preparations.

Customs had already sent Notices of Action in 2016 and 2017 flagging the same classification error on similar products. International Vitamin kept supplying the wrong codes to its brokers.

A consultant supplied corrected classifications in fall 2018. The company waited more than nine months to use them. Even then, it left the earlier duties unpaid apart from payments in response to several individual Customs notices. It had fixed tomorrow’s paperwork while keeping yesterday’s money.

The whistleblower’s complaint described a finance executive’s response to the past underpayments:

we don’t want to bring attention to that $10 million ‘bad guy.’

A finance executive, as alleged in the complaint in United States of America ex rel. Zachary Welin v. International Vitamin Corporation, Continental Agency, Inc., and MAC Customs Brokerage, Inc., paragraph 57

That alleged instruction was about the money already owed. The later settlement required $22,865,055. A better filing policy had left the old bill unpaid.

Customs Liquidation Does Not Erase Evaded Duties

Customs liquidation, when Customs fixes the final duty bill, does not erase duties the importer knowingly evaded. An importer initially deposits estimated antidumping duties, and the final amount can be higher or lower. The duty is owed when the goods arrive, before the final amount is fixed.

For someone inside the business, the useful comparison is between the entries the company knew were wrong and the corrections and payments it actually made.

Does a Customs Prior Disclosure Stop a False Claims Act Case?

Not by itself. A customs prior disclosure can shrink the customs penalty, while a False Claims Act settlement can still follow. Global Plastics disclosed, cooperated and agreed to pay. The credit it received was part of the resolution.

If your company is preparing or has made a customs prior disclosure, our whistleblower experts assess with you what it means for a possible False Claims Act case, including which old entries stayed unpaid.

Selecta Corporation, which does business as Dickies Medical Uniforms, shows what a customs interest penalty looks like beside an FCA settlement. It disclosed misclassification and undervaluation of imported apparel, principally medical scrubs and lab coats. It paid back the duties and fees. In January 2019, the trade court set its negligence penalty at $51,102, calculated as interest on the underpayments. That was a customs penalty case. Global Plastics’ resolution addressed False Claims Act claims as well.

Who Can File a Qui Tam Lawsuit?

An employee or a competitor with knowledge of customs fraud can bring a qui tam case. The Sigma case began with a competitor, Island Industries, whose prices kept being undercut by Chinese imports.

The trial evidence described by the court showed Sigma calling its products welded outlets in its catalog and on its website, but steel couplings on customs forms. Its competitor’s sales manager found the relevant antidumping order and product ruling within 24 hours. Sigma’s executive testified that the company had not seen those documents until 2017 or 2018, although both dated to 1992.

The competing business knew the product and the price. That knowledge led to the documents showing why the declared duty treatment was wrong. Taxpayers were left without money the importer owed.

A customs fraud whistleblower inside the business may know the part nobody outside it can see: when management learned of the problem and what it decided to do about it. You may know who approved leaving the old entries untouched even if you cannot calculate the entire duty bill.
