Products classified under HTS 8112.31.00.00
Unwrought Hafnium Metal Ingot
A pure hafnium ingot in unwrought form, typically produced by vacuum arc melting for use in nuclear reactor control rods and aerospace components. It falls under HTS 8112.31.00.00 as unwrought hafnium, which includes bars, rods, profiles, and unwrought forms excluding powders.
Hafnium Metal Powder
Fine hafnium powder used in powder metallurgy for manufacturing high-strength alloys and thermal spray coatings in aerospace turbines. Classified under HTS 8112.31.00.00 explicitly covering powders of hafnium.
Hafnium Scrap from Reactor Manufacturing
Waste and scrap hafnium clippings and turnings generated during machining of nuclear control rod components. Falls under HTS 8112.31.00.00 as hafnium waste and scrap.
Hafnium Turning Waste
Machining turnings and swarf from hafnium rod production for superalloys. Included in HTS 8112.31.00.00 as unwrought waste and scrap of hafnium.
Pure Hafnium Sponge
Porous hafnium sponge produced by reduction of hafnium tetrachloride, an intermediate unwrought form before further processing. Classified under HTS 8112.31.00.00 as unwrought hafnium.
Hafnium Powder for Additive Manufacturing
Spherical hafnium powder optimized for laser powder bed fusion in 3D printing aerospace parts. Falls under HTS 8112.31.00.00 as hafnium powders.
Recycled Hafnium Clippings
Clean hafnium clippings from precision machining operations, suitable for remelting. Classified as hafnium waste and scrap under HTS 8112.31.00.00.
