A de minimis exemption ruling by a three-judge panel of the US Court of International Trade has upheld the Trump administration’s authority under the International Emergency Economic Powers Act (IEEPA) to suspend duty-free treatment for imports valued under $800, dealing a defeat to a Michigan auto-parts company that had relied on the exemption to source cheaper components from China.
The court issued summary judgment in favour of the government on 13 August 2026 in Axle of Dearborn, Inc. d/b/a Detroit Axle v. Department of Commerce, rejecting constitutional and statutory challenges brought by the plaintiff in May 2025.
The De Minimis Exemption Ruling and the IEEPA Boundary
Detroit Axle had argued that President Trump’s invocation of IEEPA to rescind the de minimis exemption was unlawful in light of the Supreme Court of the United States’s decision in Learning Resources, Inc. v. Trump. That ruling, handed down on 20 February 2026 by a 6-3 majority in an opinion authored by Chief Justice John Roberts, held that IEEPA does not authorise the president to impose tariffs.
The plaintiff contended that the same logic should bar the president from eliminating the exemption under 19 U.S.C. § 1321(a)(2)(C), which permits individual importers to bring in goods below the threshold without paying duties. The court disagreed, drawing a distinction between imposing an entirely new levy and withdrawing a statutory privilege.
IEEPA permits the president to ‘nullify [or] void’ the ‘exercising of any…privilege with respect to’ transactions involving ‘any foreign country or national thereof,’ provided an ‘unusual and extraordinary threat’ has prompted a national emergency declaration. The court held that the plain text of the relevant federal statutes categorises the de minimis exemption as precisely such a privilege, and that nothing in IEEPA’s legislative history suggested Congress intended to confine that word to traditionally recognised property rights.
Because rescinding the exemption withdraws a privilege rather than exercises a legislative taxing power, the court held the action was not analogous to the tariff imposition struck down in Learning Resources, as SCOTUSblog reported when that decision was handed down. The Skadden analysis of that February ruling noted that, on the very day the Supreme Court issued its opinion, President Trump signed a fresh executive order titled ‘Continuing the Suspension of Duty-Free De Minimis Treatment for All Countries,’ expressly invoking IEEPA to keep duties running on shipments that would otherwise have qualified.
Nondelegation and the Administrative Procedure Act Claims
Detroit Axle pressed two further arguments. First, it contended that permitting the president to suspend the exemption violated the nondelegation doctrine by transferring Congress’s ‘power of the purse’ to the executive, or amounted to something akin to a line-item veto. The court rejected both formulations, finding that IEEPA supplies an ‘intelligible principle’ by restricting presidential action to the nullification of ‘privileges,’ and that bringing low-cost imports within general tariff controls during a declared emergency did not substantially alter the existing congressional tariff scheme.
Second, Detroit Axle argued that the agencies implementing the rescission had acted unlawfully under the Administrative Procedure Act (APA). The court dismissed this ground on the basis that agency action that ‘merely implements a lawful Presidential exercise of discretion… is… not subject to the APA.’
Separately, on Detroit Axle’s challenge to the IEEPA tariffs themselves (as distinct from the de minimis rescission) the court declined to rule for the government and deferred judgment, given that the Supreme Court had already resolved that question. Detroit Axle had obtained relief on that count, including reliquidation of entries without the invalid duties.
Stakes for Detroit Axle and the Wider Sector
The consequences for the plaintiff are concrete. Detroit Axle has historically sourced auto parts from Chinese manufacturers, relying on the de minimis exemption to keep retail prices down. According to Supply Chain Dive, the company stated in March 2025 that elimination of the exemption had exposed it to a 52.5% tariff on its China-sourced imports. President Trump celebrated the ruling in a Truth Social post, stating that ending the exemption makes the country safer, better protects workers, and drives additional tariff revenue to the United States.
The exemption’s legislative history runs in the opposite direction. Congress raised the de minimis threshold from $200 to $800 in 2015 through the US Trade Facilitation and Trade Enforcement Act, citing benefits to businesses, consumers, and the broader economy. The average value of most de minimis shipments has remained well below that ceiling.
The executive branch moved first. President Trump signed Executive Order 14324 on 30 July 2025, suspending duty-free de minimis treatment across all countries and all modes of entry, as recorded in the Federal Register. Congress then followed legislatively: the One Big Beautiful Bill Act, signed on 4 July 2025, statutorily repeals the de minimis exemption with effect from 1 July 2027. The Act also creates civil penalties of up to $5,000 for a first offence and up to $10,000 for each subsequent violation of the de minimis provision, per Kroll’s trade and customs analysis.
Subject to any onward appeal, the 13 August 2026 ruling confirms that the executive suspension of the de minimis exemption remains operative. With statutory repeal already enacted and set to take effect in mid-2027, importers and retailers that have structured supply chains around the $800 threshold face a narrowing window to adjust their customs and pricing models.
