U.S. imports of unwrought hafnium, hafnium powders, waste and scrap (HS 811231) totaled $11.7M in July 2026, traded with 9 countries.
Importers of Unwrought Hafnium, Hafnium Powders, Waste and Scrap paid $808K in duties in July 2026 — an effective duty rate of 8.9% on $9.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Unwrought Hafnium, Hafnium Powders, Waste and Scrap imports of $11.7M in July 2026 ran 16% below the year-to-date monthly average of $14.0M.
Last updated: July 2026 dataHafnium in unwrought form and powder — entered under 8112310000 — is a rare, dense metal extracted as a co-product of zirconium refining and valued for its exceptional neutron-absorption cross-section in nuclear reactor control rods and its high-k dielectric properties in advanced semiconductor gate oxides. Germany is the leading US import source, followed by Thailand and China, a supply pattern shaped by the limited number of facilities worldwide capable of separating hafnium from zirconium to nuclear-grade purity. Given hafnium's dual-use sensitivity in nuclear applications, exporters in source countries may require government export authorization.

Hafnium is chemically nearly identical to zirconium and occurs with it in nature, requiring costly fractional distillation or liquid-liquid extraction to separate them. Germany hosts advanced zirconium-hafnium separation and refining capacity serving the nuclear and semiconductor industries, which explains its prominence as a supplier of high-purity hafnium to the US market.
Hafnium is a dual-use material controlled under the Nuclear Suppliers Group guidelines and is subject to export licensing requirements in many countries. US importers should confirm that the exporting country's government has issued any required export authorization and that the shipment is accompanied by appropriate end-use certificates. CBP may request these documents at entry for nuclear-grade material.
