Wrong Manufacturer, Wrong ADCVD Rate: The Factory Name That Cuts the Duty

Where this happens on the Entry Summary (CBP Form 7501)

13. Manufacturer ID

Using the wrong manufacturer’s antidumping duty rate can cut an importer’s bill even when the entry names the right country. The importer buys from one factory and declares another that qualifies for a lower rate. The country field is accurate, and the government is still short. For someone in purchasing, quality control or customs brokerage, the decisive fact may be simple: you know which plant made the goods, and it is not the plant on the entry.

That is a form of antidumping duty fraud that hides inside the producer’s name. The American industry the order protects loses that protection. An honest importer has to compete against a price that leaves out part of the duty bill.

When the Actual Manufacturer Differs From the AD/CVD Entry Producer

When the actual manufacturer differs from the AD/CVD entry producer, the comparison starts with the factory that made the goods and the identity used to claim the rate. A seller’s invoice, a shipper’s name and a brand on a catalog answer different questions.

The distinctions already exist in the shipping paperwork. For ocean cargo, the Importer Security Filing separately identifies the seller, buyer, manufacturer or supplier, country of origin and container stuffing location. The broker files the entry for the importer. The business selling the goods, the plant producing them and the company supplying the broker’s instructions need to be connected to the same shipment.

The question is which business actually earned the treatment claimed on the entry, under the order that covered those goods.

Which Producer’s AD/CVD Rate Applies?

The applicable antidumping or countervailing duty rate depends on the order, the relevant producer or exporter and the period when the goods entered. The Department of Commerce sets company-specific rates for businesses it examines individually. Other producers may fall under an all-others rate.

That makes the legal company name more than a purchasing detail. We compare the declared producer and exporter with the order’s rate instructions for the entry period. Solar tariff evasion inquiries connect the actual producer to rates such as the 534.67% assigned to Solarspace in Commerce’s April 25, 2025 Cambodia determination.

How Do I Know If ADD CVD Applies?

ADD CVD applies when the goods match the written scope of the duty order. An HTS number alone does not settle coverage. The product’s materials, construction and processing need to be compared with that description before the producer’s rate can answer the duty question.

The Cash Deposit and the Final Duty Can Differ

The importer deposits estimated duties when the goods enter. Commerce can later review the period, and U.S. Customs and Border Protection computes the final duty through liquidation. The result can be higher or lower than the deposit. The Government Accountability Office’s examination of unpaid antidumping and countervailing duties explains that final bills can substantially exceed the initial deposits.

The wrong deposit rate and the duty ultimately left unpaid are connected through those same entries.

What Evidence Is Needed to Prove Fraud?

Evidence of using another producer’s antidumping deposit rate must tie the real factory to the imported goods and to the producer and rate declared to Customs. The company’s instructions and response to questions help show why the names differ.

A purchase order can identify the commercial seller. Production records can identify the plant. The entry shows what Customs was told. We join those records by product, shipment and date, then compare them with the applicable order and rate instructions. That is how a factory fact becomes a duty-loss question.

If your inspection files, lot records or factory messages identify who made a particular batch, we examine how firmly they connect that batch to the imported goods. Where a plant’s ability to produce the shipments is in question, we work through the production and factory-capacity evidence with you. Knowing which plant really made the goods is enough to start that conversation.

The same comparison extends to payment and filing instructions. What did the business buy, which producer did it claim, and who supplied that name? An insider may be the person who can connect records kept in different departments.

China-Wide Rate Versus Separate Rate: What a False Manufacturer Hides

A false manufacturer name can conceal whether the goods qualify for a separate rate or fall under the China-wide rate. To qualify for a separate rate, a Chinese producer must show it is independent of state control. The name used on the entry therefore has to be tested against both the production history and the rate eligibility.

Commerce’s August 17, 2026 review results for Chinese aluminum extrusions treated 18 companies as part of the China-wide entity at 86.01 percent because they had not supplied the documentation needed for separate-rate eligibility. For a suspected manufacturer substitution, we examine whether the importer claimed another company’s treatment for the goods actually purchased.

Evolutions Flooring Put Manufacturer Identity Inside the Case

Evolutions Flooring agreed to an $8.1 million settlement over alleged duty evasion on Chinese multilayered wood flooring. The Justice Department’s March 25, 2025 announcement describes allegedly false manufacturer identities and country-of-origin information for imports from September 1, 2019 through July 31, 2022. The duties at issue included antidumping, countervailing and Section 301 duties. A company brought the qui tam case that led to the settlement.

Customs visited factories in Thailand. Its flooring experts reviewed identified shipments, and its auditors analyzed import records and data. Customs also participated in witness interviews. The work connected the claimed production story with physical facilities, particular shipments and people who knew the trade.

Routing goods through another country does not change where they were made. Production records answer what work happened there. That is why the factory visit matters to this subject: the manufacturer’s identity is a claim about what happened on a production floor.

Who Gave the Broker the Manufacturer Name?

The broker’s instructions and correspondence can connect the declared manufacturer to the person or business that supplied the name. We compare what the importer knew about production with what it passed to the broker, including questions, warnings and later corrections. That is where knowledge and deliberate ignorance become concrete.

Grosfillex shows why the internal instruction matters. The government alleged that the furniture company presented Chinese aluminum components as finished furniture kits and left earlier declarations uncorrected after learning they were false. The whistleblower’s complaint quotes an engineering manager discussing the planned kit presentation:

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.

United States of America ex rel. Edward Wisner v. Grosfillex, Inc., whistleblower’s complaint

The message concerns how the purchase would appear to Customs. In a manufacturer case, we look for the corresponding choice about the factory name: what the business knew internally and what it instructed someone to declare.

If your job was to key in or send that name on instructions, your own part is something we handle with you. A customs fraud whistleblower may know exactly where the production account and the entry account parted company.

What a Competitor Can See

A competitor knows the product, its costs and the prices it keeps losing to. That commercial knowledge can give a factory or rate discrepancy its context. Public Commerce case documents can supply the order’s side of the comparison, while production and purchasing records supply the business’s side.

Sigma Corporation sold Chinese welded outlets while declaring them as steel couplings with no antidumping duty. A competitor brought the qui tam case, and a jury found Sigma liable. The court’s account of the product descriptions shows the value of reading the sales description beside the customs declaration. The manufacturer comparison asks an equally direct question about who made those goods.

Trade totals can help focus an inquiry. The insider’s production knowledge supplies the factory detail. Open-source information in combatting undervaluation and tax non-compliance, published in Customs Scientific Journal in 2024, found weight and value discrepancies between Ukraine’s tobacco import figures and its trading partners’ export figures. The study explains how comparisons by trading partner, period and product code can focus closer examination. We can use those patterns to focus the search for shipment and production records.

What a Wrong-Rate Whistleblower Case Can Pay

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. We assess with you how the false producer information, unpaid duty and company’s decisions fit that case.

Wrong-rate allegations also appear in Customs’ Enforce and Protect Act investigations. Its statistics as of April 8, 2026 listed use of the wrong AD/CVD rate in 17 of 462 investigations that had reached interim measures or an evasion determination.
