Products classified under Tariff item 8109.2
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.
8109.21.00Low-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.
8109.21.00Reactor-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.
8109.21.00Zirconium 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.
8109.21.00Zirconium 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.
8109.21.00Zirconium 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.
8109.29.00Aerospace-Grade Zirconium Powder
Ultra-fine zirconium powder (10-50 micron) for additive manufacturing of aircraft engine parts, valued for corrosion resistance. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
8109.29.00Industrial Zirconium Powder 99% Purity
Technical-grade zirconium powder (100-300 micron) for pyrotechnics, welding electrodes, and depilatory agents. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
8109.29.00Medical Implant Zirconium Powder
Biocompatible zirconium powder for orthopedic implants and dental prosthetics via metal injection molding. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
8109.29.00Nuclear Reactor Zirconium Powder
Low-impurity Zr-702 powder for nuclear fuel cladding fabrication, offering neutron transparency and hafnium-reduced properties. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
8109.29.00Research-Grade Zirconium Powder
Ultra-high purity (99.99%) zirconium nanopowder for scientific research in hydrogen storage and catalysis. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
8109.29.00Zirconium Alloy Powder Zr-2.5Nb
Zr-2.5% niobium alloy powder for pressure tube applications in CANDU reactors. It is classified as unwrought zirconium powder under tariff item 8109.29.00 because zirconium predominates by weight and the alloy is treated as zirconium under Section Note 5.
8109.29.00Zirconium Getter Powder
High-surface-area zirconium powder used as vacuum getters in electronic tubes and space vacuum systems. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
8109.29.00Zirconium Pigment Powder
Fine zirconium metal powder for metallic effect pigments in automotive paints and decorative coatings. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
8109.29.00Zirconium Powder 99.5% Purity
High-purity zirconium powder (99.5%) for powder metallurgy in aerospace and nuclear precision components. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
8109.29.00Zirconium Sponge Powder
Powder derived from crushed zirconium sponge, used as a precursor for further reduction processes. It is an unwrought zirconium powder, not alloyed, and falls under tariff item 8109.29.00 as 'Other' unwrought zirconium powders.
