U.S. imports of depleted uranium, thorium & related compounds (HS 284430) totaled $88K in April 2026, traded with 3 countries.
Importers of Depleted Uranium, Thorium & Related Compounds paid $4K in duties in April 2026 — an effective duty rate of 5.0% on $88K in dutiable value, based on actual customs collections rather than the published tariff schedule. Depleted Uranium, Thorium & Related Compounds imports of $88K in April 2026 ran 204% above the year-to-date monthly average of $29K.
Last updated: April 2026 dataDepleted uranium (DU) — uranium from which most U-235 has been removed during enrichment — and thorium compounds occupy this heading, covering forms ranging from DU metal (2844305010) and uranium oxide depleted in U-235 (2844302010) to thorium compounds (2844301000) and mixed materials (2844305050). DU's high density makes it commercially valuable for radiation shielding, counterweights, and certain armor applications, while thorium is of interest for advanced nuclear fuel research. France and Australia are the leading US suppliers. NRC licensing requirements apply to source material quantities, and thorium compounds may also be subject to IAEA safeguards considerations.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Depleted uranium's extremely high density — approximately 1.7 times that of lead — makes it valuable for radiation shielding in medical and industrial radiography equipment, aircraft counterweights, and certain defense applications. These non-nuclear end uses account for much of the commercial trade flow, distinct from the nuclear fuel cycle applications associated with enriched uranium.
Yes. Thorium is classified as source material under the Atomic Energy Act, and NRC import licensing requirements apply to thorium compounds above de minimis quantities, just as they do for uranium. Importers should confirm current NRC thresholds and obtain the appropriate license before shipment, as requirements can differ by compound form and intended use.
