U.S. Court of International Trade

The U.S. Court of International Trade (CIT) is a specialized Article III federal court based in New York City with exclusive nationwide jurisdiction over civil actions arising from customs duties, import transactions, and trade remedy determinations. For any importer challenging a tariff classification, any domestic industry fighting a dumped-goods decision, or any company caught in an antidumping or countervailing duty dispute, the CIT is the mandatory forum — there is no choosing a different court. Its decisions shape the practical economics of international commerce for American businesses and their foreign trading partners.

Current Law (2026)

Legal Authority

• 28 U.S.C. § 251 — Establishment (the Court of International Trade is established under Article III; consists of a chief judge and eight other judges; sits in New York City but may hold court at any port of entry or elsewhere in the United States)
• 28 U.S.C. § 252 — Tenure and salaries (judges serve during good behavior and receive the same salary as district court judges — Article III protections apply)
• 28 U.S.C. § 253 — Duties of chief judge (the chief judge has administrative authority over the court; assigns judges to cases and manages the docket)
• 28 U.S.C. § 255 — Three-judge panels (the chief judge may designate three-judge panels for particularly significant cases involving the constitutionality of an Act of Congress)
• 28 U.S.C. § 1581 — Civil actions against the United States (exclusive jurisdiction over challenges to Customs and Border Protection decisions on tariff classification, valuation, and admissibility; antidumping and countervailing duty orders; embargoes; exclusion orders; and other import-related agency actions)
• 28 U.S.C. § 1582 — Civil actions commenced by the United States (the CIT also has jurisdiction when the government brings suit to recover unpaid customs duties or to enforce trade laws)
• 28 U.S.C. § 1583 — Counterclaims (parties may bring counterclaims that would otherwise fall within CIT jurisdiction)
• 28 U.S.C. § 1585 — Powers in law and equity (the CIT has all the powers of a district court — including injunctions, declaratory judgments, and mandamus — enabling it to stay agency actions and order relief)

How It Works

The CIT's docket runs in two main streams. The first is customs litigation — disputes between importers and CBP over how goods are classified under the Harmonized Tariff Schedule, their value for duty purposes, and admissibility. A few percentage points' difference in tariff classification can mean millions of dollars for high-volume importers, making these cases economically significant even when they turn on technical classification questions. The second stream is trade remedy review — challenges to Commerce and ITC determinations in antidumping and countervailing duty investigations. Domestic industries petition Commerce and the ITC; importers and foreign governments can then challenge adverse determinations in the CIT. Most trade remedy cases are reviewed on the administrative record: the CIT examines whether Commerce or the ITC decision was supported by substantial evidence and was legally consistent, with parties submitting briefs rather than live witnesses. Customs classification cases may take additional evidence since they involve a direct dispute between importer and CBP rather than review of a regulatory proceeding. After Loper Bright (2024), courts must exercise independent judgment on statutory interpretation — a development particularly relevant to CIT cases where the meaning of tariff schedule provisions is contested.

The International Trade Commission (ITC) is an independent federal agency, not a court — it investigates whether imports injure domestic industries and conducts Section 337 IP proceedings. The CIT reviews ITC determinations on appeal; it does not independently investigate injury. ITC exclusion orders in Section 337 cases are reviewable by the CIT but also subject to presidential override for policy reasons. CIT decisions are appealed to the U.S. Court of Appeals for the Federal Circuit, which has exclusive jurisdiction over CIT appeals and provides nationwide uniform trade law — critical given the global commercial stakes. From the Federal Circuit, parties can petition the Supreme Court.

Key Numbers / Thresholds

• 9 judges with lifetime tenure (same as district judges)
• Appeals go to the Federal Circuit, not a geographic circuit court
• Antidumping duty orders can impose tariffs of hundreds of percent on targeted imports
• Commerce's final antidumping determinations typically take about 280 days (statutory deadline)
• The CIT can grant injunctions staying liquidation of entries pending litigation — a powerful remedy for importers
• Section 1581(a) customs protests must be filed with CBP within 180 days of liquidation before CIT jurisdiction attaches

How It Affects You

If you're an importer facing a CBP tariff classification or valuation dispute: After exhausting CBP's administrative protest process (you must file a protest within 180 days of liquidation), the CIT is your mandatory forum. There is no choosing a friendlier district court. Customs litigation typically turns on how goods are classified under the Harmonized Tariff Schedule — a few percentage points of difference can mean millions of dollars annually for high-volume importers. The court reviews classification questions de novo on the law, though CBP's factual findings get some deference. Customs brokers and import specialists deal with these cases routinely; the CIT bar is small and highly specialized.

If you're a domestic manufacturer facing dumped or subsidized imports: The antidumping and countervailing duty system — administered by the Commerce Department and the ITC — is your trade remedy tool. If you believe foreign competitors are selling below cost or receiving government subsidies, your industry coalition petitions Commerce and the ITC. If orders are issued, importers challenging the orders can appeal to the CIT; you can intervene as a domestic interested party. Defending antidumping orders before the CIT is as important as winning the original agency proceeding.

If you're a retailer, importer, or consumer goods company: Tariff classifications for clothing, electronics, footwear, and household goods are frequently contested — the difference between a 5% and a 20% duty on a container of goods is economically significant at scale. The CIT's decisions on classification affect retail pricing across supply chains. In periods of broad tariff increases (2018-2019 Section 301 tariffs, 2025 IEEPA tariffs), the CIT becomes a central forum for challenging the legal authority for the tariffs themselves, not just the classification of specific goods.

Pending Legislation

• HR 3292 (Rep. Kim, R-CA) — REPORT Act: would require 48-hour public notice and a 7-day congressional briefing before the President may impose emergency or discretionary tariffs under IEEPA or Section 232 — creating a legislative check on the executive tariff authority that generated the current wave of CIT litigation. Status: Introduced.
• HR 2842 (Rep. Gray, D-CA) — Stop Raising Prices on Food Act: would require congressional approval before certain new or higher tariffs on agricultural imports from top U.S. trading partners take effect — directly limiting presidential tariff authority litigated before the CIT. Status: Introduced.
• S 1867 (Sen. Whitehouse, D-RI) — Closing the De Minimis Loophole Act: would end the small-package customs exception (currently $800 per shipment) that allows many imports to enter without tariff collection or full CBP screening, requiring stricter entry data and HTS coding — significantly expanding CIT's customs enforcement docket. Status: Introduced.
• S 1449 (Sen. Peters, D-MI) — Trade Adjustment Assistance Reauthorization Act of 2025: would extend and update TAA to assist workers displaced by increased import competition, including clarifying petition windows. Status: Introduced.

Recent Developments

• IEEPA tariff litigation became the CIT's defining challenge (2025–2026), then resolved by the Supreme Court: President Trump's April 2025 executive orders imposing broad tariffs using the International Emergency Economic Powers Act — including a 10% baseline tariff on imports from most countries and much higher rates on Chinese goods (E.O. 14257) — immediately generated major CIT litigation. The central legal question: whether IEEPA grants the President authority to impose tariffs (IEEPA's text authorizes "regulating" imports in national emergencies, but tariff authority traditionally requires congressional delegation). Multiple importers and trade associations filed cases. The CIT and Federal Circuit issued conflicting rulings, and the Supreme Court resolved the question in Learning Resources, Inc. v. Trump, 607 U.S. ___ (Feb. 20, 2026), holding 6-3 (Roberts, C.J.) that IEEPA does not authorize tariffs under the major questions doctrine. The CIT now faces a wave of refund and liquidation-reopening proceedings flowing from the vacated IEEPA orders; Section 232 and Section 301 tariff dockets continue unaffected.
• Section 301 China tariff litigation generated thousands of refund claims: The Biden administration's continuation (and in some cases expansion) of Trump-era Section 301 tariffs on Chinese goods — first imposed in 2018 — generated a massive litigation backlog at the CIT. Importers filed tens of thousands of cases seeking refunds and challenging the procedural validity of the tariff lists. The Federal Circuit's upholding of the tariff authority in In re Section 301 Cases (2022) resolved the core authority question, but individual classification and exclusion disputes continue generating substantial CIT docket entries.
• De minimis exemption litigation picking up: Congress targeted the $800 per-shipment de minimis customs exemption (which allows goods shipped directly to consumers — primarily from China — to enter without tariff collection or full customs screening). Multiple bills to narrow or eliminate de minimis have been introduced; some have been included in executive tariff orders. The CIT will likely see litigation over any statutory or regulatory changes to de minimis treatment, particularly from e-commerce platforms and direct-to-consumer Chinese retailers.
• Loper Bright (2024) expanded CIT's independent review role: The Supreme Court's 2024 decision in Loper Bright Enterprises v. Raimondo, overruling Chevron deference, requires courts to exercise independent judgment on questions of statutory interpretation — not defer to agency interpretations of ambiguous statutes. For the CIT, which routinely reviews Commerce Department and ITC determinations, Loper Bright means judges must independently interpret ambiguous provisions of trade statutes rather than accepting agency constructions. This increases the CIT's significance as a venue where trade law questions are definitively resolved.
