WASHINGTON — The U.S. Court of International Trade ruled Thursday that President Donald Trump had the legal authority to eliminate the de minimis tariff exemption, which had allowed goods valued at $800 or less to enter the United States duty-free. Three judges sitting on the court upheld Trump's 2025 decision to rescind the exemption, handing the administration a legal win on one of the most contested edges of its tariff agenda.
The court found that Trump acted lawfully when he invoked the International Emergency Economic Powers Act—a 1977 law that grants presidents broad authority to regulate international commerce during a declared national emergency—to close what he described as a loophole. The ruling is notable because a separate federal court had struck down Trump's broader "liberation day" tariffs in April 2025 on IEEPA grounds, making Thursday's outcome a split in the developing body of trade-court case law on presidential tariff power.
Trump suspended the de minimis exemption as part of his wider tariff campaign targeting dozens of trading partners. He argued that the provision allowed importers to circumvent his levies by shipping goods in small parcels that fell below the $800 threshold, effectively nullifying duties on high-volume, low-cost imports. The administration framed the exemption as a structural flaw that undermined the entire tariff architecture.
The de minimis rule had been a fixture of U.S. customs law for decades, with Congress raising the threshold from $200 to $800 in 2016 to reduce administrative burden on small shipments. In practice, the higher threshold fueled an explosion in direct-to-consumer e-commerce from overseas sellers, particularly Chinese platforms. U.S. Customs and Border Protection processed more than one billion de minimis shipments in fiscal year 2023 alone, a volume that overwhelmed inspection capacity and drew bipartisan complaints in Congress about counterfeit goods and fentanyl precursors moving through the channel.
The ruling does not resolve every legal question surrounding Trump's tariff program. The April 2025 court decision blocking the liberation day tariffs—which covered broad country-by-country levies imposed under the same IEEPA authority—remains on appeal, and the administration has argued consistently that the president's emergency trade powers are sweeping and largely unreviewable. The de minimis case gave the administration a narrower but cleaner win: the court found that rescinding a specific statutory privilege fell within IEEPA's scope.
Retailers and logistics companies that built business models around the de minimis exemption face a changed operating environment. Platforms that relied on small-parcel shipping from overseas warehouses to U.S. consumers without collecting duties must now collect and remit tariffs on those shipments. The practical effect falls hardest on high-volume importers who used the exemption to price aggressively against domestic competitors.
Congress had debated closing the de minimis loophole legislatively for years before Trump acted unilaterally. Both parties acknowledged that the 2016 threshold increase had unintended consequences, but efforts to pass a statutory fix stalled repeatedly over disagreements about the threshold level, enforcement mechanisms and trade partner reactions. Trump's executive action short-circuited that debate, and Thursday's ruling removes the clearest legal path challengers had to reverse it through the courts.
The administration's legal team will use the ruling to defend the broader IEEPA tariff program still under challenge. The argument is straightforward: if the court accepts that IEEPA authorizes the president to eliminate a specific customs exemption, that same logic supports using the statute to impose duties across the board. Challengers will argue the two situations are legally distinct—that closing a privilege is categorically different from imposing new levies—and that argument will now play out in appellate proceedings.
Absent a reversal on appeal or an act of Congress, goods valued under $800 are subject to applicable duties when they enter the United States. The court has spoken on the president's authority to make that change, and the exemption that processed more than a billion shipments a year is gone.
