Detroit Axle Lawsuit Over De Minimis Tariff Elimination

Detroit Axle’s lawsuit over the elimination of the de minimis tariff exemption challenges the Trump administration’s executive orders that ended duty-free entry for imports valued under $800, a change that pushed the Michigan auto parts retailer’s effective import tax rate from 2.5% to as high as 72.5%. The case, Axle of Dearborn, Inc. v. Department of Commerce, is pending in the U.S. Court of International Trade, with oral argument on cross-motions for summary judgment set for June 23, 2026.¹

Why the Exemption Mattered to Detroit Axle

Detroit Axle sells replacement brakes, axles, suspension components, and steering gears to mechanics, dealerships, and do-it-yourself consumers across the United States. About 75% of its parts are imported from China. The company routed shipments through a facility in Juárez, Mexico, keeping individual package values below the $800 de minimis threshold set by Section 321 of the Tariff Act of 1930 and raised to $800 by the Trade Facilitation and Trade Enforcement Act of 2016. That structure kept duties at 2.5% and prices low.²³

When the exemption disappeared, CEO Mike Musheinesh described paying $725,000 in tariffs on $1 million worth of product. The company’s annual tariff bill rose from $12.5 million in 2024 to between $80 million and $90 million.⁴⁵

The Executive Orders Being Challenged

On April 2, 2025, President Trump signed Executive Order 14256, eliminating the de minimis exemption for goods from China and Hong Kong effective May 2, 2025. The stated justification was the synthetic opioid crisis, with the administration arguing that Chinese shippers were hiding illicit substances in low-value packages that bypassed customs scrutiny. The administration cited the International Emergency Economic Powers Act (IEEPA) as its legal authority.⁶

A second executive order, issued July 30, 2025, extended the suspension to all countries worldwide effective August 29, 2025. Congress separately codified the repeal in the One Big Beautiful Bill Act, signed July 4, 2025, but set the effective date at July 1, 2027, nearly two years later than the executive orders required.⁷

What Detroit Axle Is Arguing

Detroit Axle filed suit on May 16, 2025, in the U.S. Court of International Trade (Case No. 1:25-cv-00091). Defendants include the Department of Commerce, the Department of Homeland Security, the Department of the Treasury, U.S. Customs and Border Protection, and the United States itself. The company is represented by Gibson, Dunn & Crutcher, with Thomas H. Dupree Jr. as lead counsel.¹

The complaint makes three main arguments:

Congress set a mandatory $800 floor for the de minimis exemption in 19 U.S.C. § 1321, and the President cannot unilaterally override it by executive order. Any change to the threshold must go through the Secretary of the Treasury by formal notice-and-comment rulemaking, which the administration did not do.
The action was arbitrary and capricious under the Administrative Procedure Act. The government failed to consider the reliance interests of businesses that had structured operations around the century-old exemption, including Detroit Axle’s investment in its Mexico facility.
IEEPA does not authorize tariffs. The statute lets the President “regulate” imports during emergencies, but eliminating a tariff exemption is functionally the same as imposing a new tariff, which IEEPA does not permit.

Detroit Axle is seeking an injunction against the suspension and a refund of roughly $44 million in tariffs it says it has paid under the challenged orders. About $9 million of that relates directly to IEEPA tariffs, with the rest tied to other duty categories.⁸⁹

The Government’s Defense

In a May 2026 filing, the Justice Department argued that suspending the de minimis exemption is not a new tariff at all. It simply allows existing tariff rates to apply to shipments that had previously entered duty-free. The DOJ also challenged Detroit Axle’s standing to seek compensation, contending the company chose to act as the “importer of record” and pay duties directly rather than pass them to customers.⁹

The government raised a further practical objection: Detroit Axle’s auto parts imports from Mexico may not have qualified for de minimis treatment in the first place, because auto parts are subject to National Highway Traffic Safety Administration regulations that disqualify them from the simplified customs entry process the exemption relies on. Earlier in the case, the DOJ also argued Detroit Axle had delayed filing suit for two weeks after the policy took effect, undermining its claim of irreparable harm.³

How the Supreme Court’s IEEPA Ruling Changed the Case

The case was largely on hold for months while a separate challenge to IEEPA tariffs moved up the appellate ladder. On July 28, 2025, a three-judge panel denied Detroit Axle’s preliminary injunction, finding the requested relief redundant of an existing injunction in V.O.S. Selections, Inc. v. United States, and stayed the rest of the case pending that appeal.¹⁰

The Federal Circuit affirmed the invalidation of the IEEPA tariffs en banc on August 29, 2025, holding that authority to “regulate” imports does not include the power to levy tariffs, and noting that IEEPA contains no reference to “tariffs,” “duties,” or “taxes.” On February 20, 2026, the U.S. Supreme Court affirmed 6-3. Chief Justice Roberts, writing for the majority, applied the major questions doctrine and concluded that Congress would not have delegated something as consequential as the power to tax through IEEPA’s ambiguous language.¹¹

Despite that ruling, President Trump signed a new executive order the same day directing Customs and Border Protection to continue suspending de minimis treatment. The administration’s position is that the de minimis suspension rests on legal grounds distinct from the tariff authority the Supreme Court struck down.⁴

The Court of International Trade lifted the stay on March 5, 2026, and allowed Detroit Axle to file an amended complaint incorporating the Supreme Court decision and the One Big Beautiful Bill Act. Dupree said publicly that “the Supreme Court’s decision made clear that the de minimis repeal was unlawful.”¹²

Can Detroit Axle Get Its Money Back?

The refund question turns on a related ruling. In AGS Company Automotive Solutions v. U.S. Customs and Border Protection (December 2025), the Court of International Trade confirmed it has the power to order “reliquidation” of entries and issue refunds if IEEPA tariffs are ultimately deemed unlawful. The government did not oppose that authority in AGS, and the court held the government judicially estopped from reversing course, because it had used the promise of future refunds to argue in both V.O.S. Selections and the Detroit Axle case that importers were not suffering irreparable harm.¹³

The DOJ has nonetheless resisted Detroit Axle’s specific refund claims, arguing that eliminating a tariff exemption is not the same as imposing a tariff. If that distinction holds, the Supreme Court’s IEEPA ruling would not directly reach the de minimis suspension.⁹

What a Win Would and Would Not Fix

The One Big Beautiful Bill Act permanently eliminates the de minimis exemption on July 1, 2027, regardless of how the lawsuit turns out. A ruling for Detroit Axle would only affect the window between the executive orders and that legislative cutoff. For a company that has paid tens of millions of dollars in tariffs during that window, the financial stakes are still substantial.⁵

Where the Case Stands Now

Cross-motions for summary judgment are fully briefed. Oral argument is scheduled for June 23, 2026, at the James L. Watson Courthouse in New York. The three-judge panel will decide whether the executive suspension of the de minimis exemption was lawful, whether IEEPA provided adequate authority, and whether Detroit Axle is entitled to the refund it seeks.¹
