High-Purity Zr Granules Low-Hafnium
High-purity zirconium granules in unwrought form, containing less than 1 part hafnium per 500 parts zirconium by weight. These granules are used as melting stock for vacuum arc melting to produce sputtering targets and thin-film deposition materials.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the hafnium content is documented with a certificate of analysis to confirm it meets the <1:500 ratio
• Declare the granules as unwrought zirconium, not as articles, to avoid misclassification
• Check if the granules qualify for duty-free treatment under a free trade agreement

Low-Hafnium Zirconium Ingots
Low-hafnium zirconium ingots in unwrought form, with hafnium content below 1 part per 500 parts zirconium by weight. These ingots are used in nuclear reactor components and chemical processing equipment due to their high purity and corrosion resistance.
Reactor-Grade Zirconium Billets
Reactor-grade zirconium billets with hafnium content of 0.018% or less, meeting the <1:500 ratio. These semi-finished billets are in unwrought form, not yet hot or cold worked, and are intended for forging into tubesheets for pressurized water reactors.
Zirconium Pigs Nuclear Grade
Cast zirconium pigs produced via the Kroll process, with hafnium content below 0.2% (less than 1:500 ratio). These unwrought pigs weigh 25-50 kg each and are used as primary material for remelting into reactor cladding.
Zirconium Powder 99.5% Pure Low-Hafnium
Atomized zirconium powder with 99.5% purity and hafnium content below the 1:500 ratio. This unwrought powder, with particle size -100 mesh, is used in powder metallurgy and additive manufacturing applications.
Zirconium Sponge Low-Hafnium Nuclear
Kroll process zirconium sponge in porous, unwrought form, with hafnium content below 0.2% (less than 1:500 ratio). This vacuum-distilled sponge is a standard precursor for Zircaloy fuel cladding and has not been pressed or compacted.
