Aluminum Extrusions and the False Claims Act: AD/CVD, Section 232, and Transshipment Fraud

Aluminum extrusions from China have been subject to antidumping and countervailing duty orders since 2011, with combined duty rates that can exceed 300 percent. In October 2023, the U.S. Aluminum Extruders Coalition filed new AD/CVD petitions covering fifteen additional countries, requesting duties as high as 256 percent. The combination of punishing duty rates, broad product scope, and widespread evasion has made aluminum extrusions one of the most litigated product categories in customs fraud—and one of the most promising for False Claims Act whistleblowers.

A Product That Touches Everything

Aluminum extrusions are produced by forcing heated aluminum alloy through a die to create profiles with fixed cross-sections—channels, angles, tubes, bars, and custom shapes used in virtually every sector of the economy. They appear in window frames and curtain walls, shower doors and bathroom enclosures, solar panel mounting systems, heat sinks for electronics, automotive trim and structural components, furniture, fencing, railings, and thousands of industrial applications. The United States imports billions of dollars in aluminum extrusions annually, and China has historically been the dominant supplier.

The breadth of the product category is itself a source of classification and compliance complexity. The AD/CVD orders on aluminum extrusions from China have one of the widest scope definitions in trade law. The scope covers shapes and profiles “whether or not finished,” including those that have been “fabricated, i.e., heat treated, anodized, painted, or otherwise coated or finished.” It covers extrusions that are parts or subassemblies of larger products—even when those products are not themselves made of aluminum. If a refrigerator shelf subassembly contains extruded aluminum framing, the aluminum component is within the scope of the orders even though the finished product is a refrigerator part, not an “aluminum extrusion” in any common-sense understanding of the term.

The Duty Landscape: Three Layers of Exposure

Importers of aluminum extrusions may face three independent layers of duties, each creating its own evasion incentive.

First, the AD/CVD orders. The original 2011 orders on aluminum extrusions from China imposed antidumping duties ranging from roughly 33 to over 374 percent, plus countervailing duties. For importers without an individually determined rate, the “China-wide” rate effectively prices Chinese-origin extrusions out of the U.S. market at lawful duty levels. In October 2023, the U.S. Aluminum Extruders Coalition filed new petitions targeting fifteen additional countries—Colombia, the Dominican Republic, Ecuador, India, Indonesia, Italy, Malaysia, Mexico, South Korea, Taiwan, Thailand, Turkey, the UAE, and Vietnam—requesting antidumping duties as high as 256 percent. This dramatic expansion aims to close the transshipment routes that opened after the 2011 orders made direct importation from China uneconomical.

Second, Section 232 tariffs. Since 2018, aluminum articles imported into the United States have been subject to a 10 percent tariff under Section 232 of the Trade Expansion Act of 1962. Unlike AD/CVD duties, Section 232 tariffs apply regardless of the country of origin (subject to limited exclusions and quota arrangements). An importer that successfully evades AD/CVD duties by transshipping Chinese extrusions through a third country still owes Section 232 duties—but an importer that undervalues the extrusions or misclassifies them as a non-aluminum product can evade both.

Third, Section 301 tariffs. Chinese-origin goods, including aluminum extrusions, are also subject to Section 301 tariffs that currently reach 25 percent. An importer that falsely declares a Chinese-origin extrusion as a product of Vietnam evades the Section 301 tariff in addition to the AD/CVD duties.

The arithmetic is staggering. An aluminum extrusion that should lawfully bear antidumping duties of 33 percent, countervailing duties of 20 percent, Section 232 duties of 10 percent, and Section 301 tariffs of 25 percent would owe combined duties exceeding 88 percent of its declared value. A China-wide-rate extrusion could face combined duties well over 400 percent. The incentive to evade is correspondingly enormous.

Tai Shan Golden Gain: The Landmark FCA Aluminum Case

The leading False Claims Act case on aluminum extrusion transshipment is United States ex rel. Valenti v. Tai Shan Golden Gain Aluminum Products Ltd. Four U.S. manufacturers of shower doors and enclosures allegedly colluded to evade AD/CVD duties on aluminum extrusions they imported from the Chinese manufacturer Tai Shan Golden Gain. The defendants created a shell company in Malaysia—Northeastern Aluminum Corp.—to serve as a front. Chinese-manufactured extrusions were shipped to Malaysia, repackaged, relabeled as Malaysian in origin, and re-exported to the United States. No substantial transformation occurred in Malaysia.

The fraud was discovered by a Florida-based trade consultant who worked in the Asia-Pacific aluminum trade. He filed a qui tam lawsuit in 2013. The government intervened, and the defendants settled for a total of $4.5 million. The largest single settlement was $1.1 million by Ohio-based Basco Manufacturing Co. The whistleblower received 18 percent of the recovery—approximately $555,000—as his share under the FCA’s qui tam provisions.

The case illustrates several features that recur in aluminum extrusion fraud. The shell company in the transshipment country. The minimal or nonexistent processing that fails to constitute substantial transformation. The false country-of-origin declarations on CBP Form 7501. And the qui tam whistleblower who, by virtue of his position in the industry, could see the fraud that CBP could not.

Harman International: When the Product “Isn’t” an Extrusion

A different evasion strategy surfaced in the Harman International case, which settled in late 2025 for $11.8 million. Harman International Industries—the audio electronics company behind JBL, Harman Kardon, and Mark Levinson—imported heat sinks containing extruded aluminum from China. The government alleged that Harman knowingly failed to declare the merchandise as subject to AD/CVD orders and failed to pay the required cash deposits—for over a decade, from June 2011 through March 2023.

The Harman case highlights a particularly insidious form of evasion: scope avoidance. Because the AD/CVD scope covers aluminum extrusion components even when they are incorporated into larger products, importers of finished goods containing extruded aluminum parts must determine whether their products fall within the orders’ scope. The scope language is extraordinarily broad and has been the subject of numerous Commerce Department scope rulings. An importer that classifies a product as a “heat sink” or “electronic component” rather than an “aluminum extrusion” may avoid triggering AD/CVD duties on paper—but if the aluminum component is within the orders’ scope as a matter of law, the entry is false.

CBP observed that the case “underscores CBP’s commitment to enforcing the customs and trade laws and ensuring the protection of revenue to promote the U.S. economic security.”

EAPA: CBP’s Administrative Enforcement Tool

Beyond the False Claims Act, CBP has its own administrative enforcement mechanism for AD/CVD evasion: the Enforce and Protect Act (EAPA), enacted in 2016. EAPA allows domestic manufacturers or other interested parties to file allegations of evasion directly with CBP, which then investigates and can impose interim measures—including suspension of liquidation and cash deposit requirements—within 90 days.

Aluminum extrusions have been among the most frequent subjects of EAPA investigations. In one recent case, CBP issued determinations against Florida Aluminum Extrusion LLC, Hialeah Aluminum Supply, and Global Aluminum Distributor for evading AD/CVD orders by transshipping Chinese-origin extrusions through third countries. The EAPA archive at CBP reflects a steady stream of aluminum-related investigations, often involving the same transshipment corridors—Malaysia, Vietnam, Thailand, and the UAE—that the new 2023 petitions seek to close.

For potential whistleblowers, EAPA and the FCA are complementary tools. An EAPA filing targets the specific shipments and triggers CBP investigation. An FCA qui tam action targets the broader pattern of false claims and provides the whistleblower with a financial incentive—a share of the government’s treble damages recovery—that EAPA does not offer. In some cases, information developed through an EAPA investigation can support or supplement an FCA complaint.

What Employees Should Watch For

The aluminum extrusion supply chain involves manufacturers, trading companies, freight forwarders, customs brokers, and end-user fabricators. Employees at any point in this chain may observe indicators of fraud:

Unexplained routing through a third country. Aluminum extrusions manufactured in China that are shipped to Vietnam, Malaysia, or the UAE before re-export to the United States—particularly if the intermediate stop involves nothing more than repackaging or relabeling.

Products entered without AD/CVD declarations. If an importer brings in aluminum extrusions from any source and the entry documentation does not reflect an AD/CVD case number or cash deposit, the importer may be evading the orders—either by misrepresenting the country of origin or by claiming the product is outside the scope.

Scope determinations that seem too convenient. Finished products containing obvious aluminum extrusion components—heat sinks, frames, brackets, mounting systems—that are entered without any AD/CVD assessment. The question is always whether the aluminum extrusion component falls within the orders’ scope, and the answer is frequently yes.

Misclassification to avoid Chapter 76 entirely. An importer that classifies an aluminum extrusion under a heading for “parts” of another product (e.g., Chapter 84 for machinery parts or Chapter 94 for furniture parts) rather than under Chapter 76 (aluminum and articles thereof) may be attempting to avoid both AD/CVD flagging and Section 232 duties.

The expansion of AD/CVD coverage to fifteen new countries signals that the U.S. government and domestic industry recognize the scale of the evasion problem. As traditional transshipment routes face new duties, importers will seek new routes and new evasion strategies. Employees with knowledge of these schemes can play a critical role in enforcement—and the False Claims Act provides both the legal mechanism and the financial incentive to do so.
