The $12,405,000 Allied Stone customs settlement covered a simple allegation: quartz for the customer, marble or crystallized glass for Customs. Allied Stone is a Dallas supplier of countertops and cabinetry. The former processing executive who brought the customs fraud case described having to unwrap slabs and match their crate to a packing list to identify the stone.
The Department of Justice alleged antidumping duty fraud: Allied Stone misrepresented Chinese quartz surfaces as marble or crystallized glass to evade antidumping and countervailing duties. Its August 19, 2025 settlement announcement covered imports from September 29, 2018 through February 7, 2023.
In the government’s account, the marble and glass descriptions carried lesser duties than the Chinese quartz actually imported. The business could sell quartz while presenting Customs with a different material.
The written duty order describes the goods it covers.
The incentive to change a product’s description shows up in trade data, too. Measuring Tariff Evasion and Smuggling, published in NBER Reporter in 2009, reported evidence from Hong Kong exports to mainland China that goods were being declared as similar products carrying lower tariffs. The Allied allegation concerns Chinese goods entering the United States, with the same basic incentive to give the product a less expensive name at the border.
We connect customs entry evidence to the actual product, shipment and people who supplied its description. Allied’s whistleblower brought the product knowledge of a processing executive.
Her account of one crate makes the alleged concealment tangible:
Further, the slabs inside Crate Number 26 were unlabeled and covered with several layers of paper and plastic. [The processing executive] had to remove the layers of paper and plastic and compare the sparse information on the crate label with the information on Allied’s packing list for container number ZCSU2696618, Ex. 12, to discover that these slabs were, in fact, “Blizzard” quartz.
That comparison gave a physical slab a product name and a shipment identity. The complaint also alleges that quartz crate labels omitted the stone type, intended use, color name and origin. Those details mattered to the people getting countertops into a building, too.
The processing executive said her job required her to assemble stone drawings, accessories such as sinks, stone colors and estimated installation dates. She sent them to senior management, but typically heard nothing back about container numbers, packing lists or arrival dates until the day after a container arrived and delivery had to be arranged. The person planning the installation was allegedly being kept from the information needed to receive the stone.
A warehouse change opened part of the shipping trail. The complaint says she persuaded Allied to use a third-party logistics company because slabs stored on job sites were easily broken. Only then did she gain access to container numbers. The logistics company also struggled to get shipping information. According to the complaint, import data showed Allied bringing in dozens of containers of Chinese quartz a month until the duties came in during fall 2018, then seemingly stopping. Yet Chinese quartz containers were arriving again by 2020, and the ones she saw did not appear in Allied’s data.
The customs entry summary records the declared value, classification and duty rate. A crystallized glass description on a Chinese quartz entry is the kind of mismatch we trace through supplier messages and internal approvals to whoever directed the switch.
There is a concrete quartz example in Customs’ November 2021 determination involving other importers. Customs matched GHS Group’s product drawings and shipping records to its customs declaration. It found that GHS had declared quartz surface products as bathroom vanities under a wooden-furniture classification.
Customs Tariff Classification and the Use of Assistive Technologies, published in World Customs Journal in 2024, describes how companies attach tariff classifications to product identifiers such as catalog numbers and stock-keeping units. It also reports supplier invoice codes and previous shipment codes being reused as classification shortcuts. That makes a product identifier useful beyond the warehouse: it can connect the specifications and purchase records to the description passed along for customs filing.
Production records, the factory’s capabilities and the form of the finished product connect a claimed country of origin to what was actually made there. In stone processing, a factory exporting full slabs and one supplying quartz cut to a project’s dimensions are doing different work.
The Allied whistleblower’s complaint described a Singapore route alongside the product-description allegations. It alleged that Allied Supply concealed Chinese quartz as granite and routed it through Singapore using Richen Stone as a newly created dummy importer in the United States. The whistleblower also alleged false Singapore origin declarations for quartz supplied to a multifamily housing project.
The complaint questioned a claimed Philippine source on a more specific ground. The whistleblower alleged that, as of June 2020, Philippine quartz factories were exporting full slabs to the United States, but none exported cut-to-size quartz products. Her point was about the form of the stone the project needed and whether the claimed source supplied it.
The distinction between making quartz and cutting it mattered in Customs’ separate 2021 investigation of Malaysian shipments. Customs explained that cutting or further fabricating Chinese quartz in Malaysia did not make it Malaysian-origin under the duty orders. The quartz had to be produced there from raw materials. It also found that Stone Direct’s documented raw-material purchases fell short of the quartz in the matching production records.
The Evolutions Flooring case shows how an asserted manufacturing location can be checked. The government alleged false manufacturer and origin information for Chinese flooring. The Justice Department’s announcement described factory visits in Thailand, shipment reviews by flooring specialists and import-record analysis.
The Justice Department also alleged that Allied Stone and its president failed to ensure that manufacturers and third parties serving as importers of record declared and paid the applicable duties. The allegation reached the people responsible for the arrangements as well as the company named on the entry.
The complaint describes information passing through management and intermediaries before it reached the people doing the work. It alleges that identifying information was redacted from documents sent to Allied’s drafting team and that a Singapore intermediary concealed the Chinese factory’s location. Those allegations make what the participants knew a practical question about who supplied, changed or withheld information.
We compare the purchasing and production records with the customs broker’s instructions and filed entry. That connects the stone to the decisions behind its declaration. Under the False Claims Act, knowingly avoiding a duty bill supports a whistleblower case even though the importer never asked the government to pay it.
The whistleblower alleged that Allied was winning bids at prices at or below Republic Elite’s own cost to buy the quartz. Her complaint attributed that account to a Republic Elite contact and its management. She also alleged that paying the duties would have made Chinese quartz uneconomic for one project. The alleged advantage reached the project bid, not just the customs form.
Competitors paying the duties have to cover a cost the evader leaves out, and taxpayers lose the money owed to them. The American quartz producers the duties protect lose that protection when covered imports enter under another description.
A competitor brought the case against Sigma Corporation, which marketed Chinese welded outlets as welded outlets while describing them to Customs as steel couplings and declaring that no antidumping duty applied. A jury found Sigma liable under the False Claims Act. The commercial name and the customs name described the same goods. Someone who knew the product could recognize the difference.
The settlement agreement assigns $12,300,000 to Allied Stone and $105,000 to its president.
The Justice Department announced about $2.2 million of the settlement as the customs fraud whistleblower reward. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.
Here, the whistleblower inside the stone business brought knowledge of processing, project requirements and the shipments she encountered. A slab, a drawing and a packing list were part of her ordinary work. They also gave her a way to challenge the account of what Allied was importing.
