On August 13, 2026, the U.S. Court of International Trade (USCIT) issued a significant decision for importers that have relied on Section 321 de minimis treatment. In Axle of Dearborn, Inc. d/b/a Detroit Axle v. Department of Commerce, Slip Op. 26-94, a three-judge panel (Katzmann, Reif, and Restani, JJ., per curiam) granted summary judgment for the government, upholding the President's rescission of duty-free de minimis treatment under the International Emergency Economic Powers Act (IEEPA). Although the challenge originated with the China-specific orders, the amended complaint — and the court's holding — reaches the worldwide suspension of de minimis treatment under Executive Order 14324 (effective August 29, 2025) and Executive Order 14388 (continuing the suspension following the Supreme Court's decision in Learning Resources).

The court's reasoning turned on IEEPA's authorization for the President, during a declared national emergency, to "nullify, void, prevent or prohibit . . . exercising any right, power, or privilege" with respect to property in which a foreign country or national has an interest. The court held that the de minimis exemption is, by its own statutory terms, a "privilege": 19 U.S.C. § 1321 twice describes duty-free entry in exactly those words, and Congress reinforced that characterization in the One Big Beautiful Bill Act's legislative history. Suspending that privilege therefore falls squarely within IEEPA's text.

The court distinguished Learning Resources, where the Supreme Court held that IEEPA does not authorize the President to impose tariffs. Suspending the de minimis exemption, the court reasoned, imposes no new duties — it merely subjects low-value goods to the same duties Congress has already imposed on identical goods valued above $800. The suspension accordingly implicates neither the power of the purse at issue in Learning Resources nor the legislative power at issue in Clinton v. City of New York; the court analogized instead to the tariff-suspension authority upheld in Field v. Clark.

Importantly for the broader trade bar, the court articulated a limiting principle: because Congress expressly designated de minimis treatment a "privilege," the holding has no implication for trade statutes not so designated. The court specifically rejected the argument that this reading would let the President override provisions such as Section 122's 15 percent, 150-day limits, which it characterized as restrictions on presidential authority rather than importer privileges.

The court also rejected Detroit Axle's Administrative Procedure Act challenge. Applying Franklin v. Massachusetts, it held that agency actions implementing the President's directive were purely ministerial — the implementing agencies exercised no discretion — and are therefore not subject to APA arbitrary-and-capricious review. Such actions remain reviewable as presidential action for constitutional or statutory excess, but not under the APA.

Notably, the court declined to grant the government summary judgment on Detroit Axle's remaining count challenging the IEEPA tariffs themselves, deferring judgment in light of Learning Resources. The court observed that a separate order in V.O.S. Selections directing CBP to liquidate and reliquidate entries without regard to IEEPA duties is currently on appeal at the Federal Circuit — the proceeding importers seeking IEEPA duty refunds should be watching.

Implications for importers. The decision confirms that the de minimis suspension stands on independent legal footing from the invalidated IEEPA tariffs, and the practical runway is short in any event: CBP's June 24, 2026 interim rules suspend the exemption indefinitely by regulation, and the One Big Beautiful Bill Act repeals the statutory exemption outright effective July 1, 2027. Any successful appeal would therefore matter principally for duties paid on low-value shipments between August 29, 2025 and July 1, 2027. Companies that built low-value direct-to-consumer, marketplace fulfillment, or cross-border parcel models around Section 321 should treat the suspension as durable, quantify the historical duty exposure and potential refund position for that window, and assess de minimis exposure separately from ordinary tariff exposure — including classification, origin, entry type, data quality, and customs broker readiness.
