Last updated: August 2026 dataNuclear-grade zirconium powder — defined by a hafnium-to-zirconium ratio of less than 1:500 by weight — is a tightly specified material used primarily in nuclear fuel cladding and reactor components, where hafnium's high neutron-absorption cross-section must be minimized. China is the leading US supplier of this grade, and imports from China are subject to Section 301 tariffs; France and Germany are also significant sources. Because this material can intersect with nuclear nonproliferation controls, importers should confirm whether any applicable export licensing or end-use certificate requirements were satisfied in the country of export before entry.

The 1:500 hafnium-to-zirconium threshold is the defining split between nuclear-grade (low-hafnium) and commercial-grade zirconium in the US tariff schedule. Nuclear-grade material with hafnium below this threshold is classified under 8109210000, while zirconium powders not meeting this specification fall under the NESOI heading 8109290000. Chemical analysis documentation from the producer is essential to support the correct classification at entry.
Low-hafnium zirconium powder intended for nuclear applications may be subject to Nuclear Regulatory Commission (NRC) or Department of Energy oversight depending on the specific end use and destination. Importers should verify whether the foreign supplier obtained any required export authorization and whether the US end user holds the appropriate NRC license. Consulting a licensed customs broker with experience in nuclear materials is strongly advisable.
