False Free-Trade Preference Claims: When the Factory Changes but the Certificate Does Not

False free-trade preference claims let an importer pay less duty by claiming that goods meet origin requirements their production does not support. The problem can start with an ordinary sourcing change: a different factory, different materials, an old certificate still going to the broker. The serious problem starts when the company learns the goods no longer qualify and keeps claiming the benefit. Sourcing knows the production changed. U.S. Customs and Border Protection keeps getting the old story.

What Is False Certificate of Origin Customs Fraud?

False certificate of origin customs fraud means knowingly using false origin information to obtain a duty benefit the goods do not qualify for. A complete certificate can tell a false story about production. The signature cannot do the manufacturing.

The materials, processing, costs and dates have to support the certificate. Knowingly using a false certificate of origin to escape duty cheats the competitor that paid the full duty and taxpayers. A customs whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

What Is the Difference Between Preferential and Non-Preferential Origin?

Preferential origin determines whether goods qualify for a trade agreement or preference program’s lower duty. Non-preferential origin serves other purposes, including ordinary duty treatment and country-of-origin marking. Country of origin fraud has to be tested against the rule behind the particular claim.

Marking and duty rules can give different answers for the same article. Country of origin marking duty fraud concerns a separate duty obligation when goods lack the required marking.

Non-preferential origin can turn on substantial transformation: whether processing created an article with a new name, character and use. Preference rules can use tariff classifications and regional value content, the qualifying value the producer added. Production evidence in a country of origin fraud case has to answer the applicable question.

The product’s tariff classification matters here too. Customs Tariff Classification and the Use of Assistive Technologies, published in World Customs Journal in 2024, explains that commodity codes underpin preferential origin rules and that a deliberately wrong code can produce a more favorable preference outcome.

USMCA Certificates Need Facts Behind the Form

A USMCA claim rests on the importer’s assertion that the goods qualify. Customs’ USMCA guidance permits certification in any format containing nine minimum data elements. A regional value-content claim depends on the producer’s bill of materials and costs. The importer may be making a claim about a foreign production process it never ran.

Customs verifies the origin records afterward. If those records fail to support the preference, the ordinary rate applies retroactively.

Supplier Changed Factory but Origin Certificate Unchanged

When a supplier changed factory but the origin certificate stayed unchanged, the question is which production requirement changed with it. A manufacturing-country change can leave an old preference claim attached to goods that no longer qualify. The certificate, production records and entry dates have to describe the same imports.

The story runs through the sourcing change, the affected production, the certificate sent to the customs broker, and the instruction to claim the benefit. A supplier invoice identifies a commercial transaction. The factory’s materials and processing records explain what happened to the goods.

An internal email can reveal what the extra stop was for. In the whistleblower’s complaint against Everlight Electronics, an employee questioned the delay in shipping Chinese LED products through Taiwan:

Our lead-time increase 1 week because HQ needs to send to Taiwan to switch label from China? We don’t have anything directly [s]hip from China, is that true?

Internal email quoted in the whistleblower’s complaint, United States ex rel. Tao Wang v. Everlight Electronics Co., Ltd., et al.

The complaint alleges that the company changed Chinese origin labels to Taiwanese ones without substantial changes to the products. In transshipment tariff evasion cases, shipping time and internal instructions can expose the purpose of the route. Here, the email puts the label change inside the company’s discussion of delivery time.

What Evidence Is Needed to Prove Fraud?

For a false preference claim, the evidence connects the certificate to the actual production, the duty left unpaid and what the company knew. A whistleblower inside the supply chain may see the crucial connection before anyone compares the files.

Sourcing knows the factory, the producer holds the bill of materials, and finance has the costs behind a value-content claim. Logistics sees the route. A customs broker whistleblower may know who supplied the certificate and instructed the preference claim.

Ocean cargo leaves several accounts of the same shipment. Before loading abroad, the Importer Security Filing identifies the seller, buyer, manufacturer or supplier, and origin. The carrier files a separate manifest. The bill of lading, invoice and entry summary come from different participants at different times. Connecting them can show where the account of the goods changed.

That comparison needs shipment-level precision. The 2020 Center for Economic Studies paper Are Customs Records Consistent Across Countries? Evidence from the U.S. and Colombia matched only 27% of U.S. transactions within its buyer-seller pairs using product codes, export dates and values. It recommends common invoice or manifest numbers to connect the records.

The paper also explains that shipping country and country of origin are separate fields: Colombian goods passing through a Panamanian wholesaler can carry Panama as shipping country and Colombia as origin. We follow the transaction back to its production, rather than treating the last port as the factory.

Jewelry Import Duty Fraud and False Preferences

Jewelry import duty fraud can turn on the value added in the country named in the preference claim. In its June 2018 resolution, Temple St. Clair, LLC agreed to pay $796,000 over customs practices that included improper Generalized System of Preferences claims on jewelry from Thailand and Sri Lanka from 2011 through July 2016. The company admitted underpaying customs duties and failing to mark merchandise properly.

The historical requirement included a 35% regional-value threshold. That puts the producer’s materials and costs at the center of the preference question. The same resolution also addressed undervaluation, undeclared hand-carried commercial jewelry and missing origin markings. Each practice changes a different part of the duty bill.

The unit on the invoice can matter as much as the country. In a separate civil case, TSI Accessories Group allegedly declared a card holding several pairs of earrings as a single pair. That increased the stated value per pair and put the Chinese earrings in a lower-duty category. For a jewelry insider, the distinction between a card, a pair, the materials and the finished piece can explain why the duty calculation is wrong.

What Other Customs Cases Show

False trade preferences have already featured in a substantial civil whistleblower settlement. Linde GmbH and Linde Engineering North America LLC agreed to pay more than $22.2 million in September 2020 over allegations involving the nature, classification, value and free-trade eligibility of imports used in construction projects. The goods themselves were valued at more than $500 million. The whistleblower’s share was approximately $3.7 million.

A claimed factory can also be tested against what it actually produces. In the Evolutions Flooring case, the government alleged false manufacturer and origin information for Chinese multilayered wood flooring. Customs’ investigation included factory visits in Thailand, shipment reviews by flooring specialists, import-record analysis and witness interviews. That is what examining the production behind the paperwork looks like.

Production changes can also change the alleged mechanism. The Everlight settlement announcement describes Chinese LEDs allegedly routed through Taiwan from July 2018 to January 2022. For January 2022 through November 2025, it describes a different problem: LED dice of different origins allegedly were not segregated to support the declared origin. The same country on successive declarations can rest on different production facts.

When the Company Knows the Certificate Is Wrong

Knowledge connects the production failure to a whistleblower case. In customs fraud, deliberate ignorance can matter alongside an explicit instruction. The certificate, the warning and the entries made afterward belong in the same account of what the company knew.

Customs may also create a dated record of the question. Its Form 28 requests support for a declaration, while Form 29 announces a proposed or completed change to classification, value or rate. An insider may know what the company had already learned before that inquiry arrived.

What the company did after learning the claim was wrong belongs in that same timeline. In the Grosfillex settlement, the government alleged that earlier customs declarations remained uncorrected after the company learned they were false. The relevant decisions include both the new claims and the unpaid duties attached to old ones.

Under the customs refund law, a preference refund claimed after import still depends on the goods qualifying when they entered. A later signature cannot supply a production step that never happened.

The importer remains responsible for its duties when a broker files. The Justice Department also says its trade-fraud work reaches brokers, distributors and commercial users who knowingly profit from improperly imported goods. The person who presses submit may be only one participant in the decision to claim the preference.
