Products classified under Tariff item 8109.31.00.00
Aerospace Zirconium Alloy Borings
Fine borings generated from drilling zirconium components used in aircraft engines. These are classified as waste and scrap under tariff item 8109.31.00 because they are fragmented, not usable as original articles, and contain less than 1 part hafnium to 500 parts zirconium by weight, making them suitable for remelting into high-purity alloys.
8109.31.00Lab Equipment Zirconium Scrap
Broken crucibles and boats used in analytical laboratories, made of low-hafnium zirconium. These items are no longer usable for their original purpose due to breakage, classifying them as waste and scrap under tariff item 8109.31.00, provided they meet the hafnium content requirement.
8109.31.00Low-Hafnium Zirconium Turning Scrap
Machining turnings and chips from zirconium alloy aerospace parts, with hafnium content below the 1:500 ratio. These are fragmented and unsuitable for direct use, qualifying as waste and scrap under tariff item 8109.31.00, distinct from wrought articles.
8109.31.00Naval Zirconium Propeller Scrap
Scrap from corroded zirconium propeller shafts used in submarines, with low hafnium content. The material is waste and scrap under tariff item 8109.31.00 because it is no longer usable as a shaft due to corrosion, and it meets the hafnium specification.
8109.31.00Pharmaceutical Reactor Zirconium Scrap
Cuttings and offcuts from zirconium vessels used in pharmaceutical API synthesis, with hafnium content compliant with the 1:500 ratio. These are fabrication waste, classified as waste and scrap under tariff item 8109.31.00, not as usable articles.
8109.31.00Salt Bath Furnace Liners Scrap
Degraded zirconium liners from heat treating furnaces, with low hafnium content. The liners are no longer functional due to wear and thermal damage, classifying them as waste and scrap under tariff item 8109.31.00.
8109.31.00Test Sample Zirconium Clippings
Small clippings from quality control tests on zirconium sheets for medical implants, with hafnium content under the limit. These are lab-generated scrap, classified under tariff item 8109.31.00 as waste and scrap.
8109.31.00Zirconium Anode Scrap
Spent sacrificial anodes from electroplating tanks, made of low-hafnium zirconium. The anodes are depleted and no longer functional, classifying them as waste and scrap under tariff item 8109.31.00.
8109.31.00Zirconium Chemical Processing Vessel Scrap
Demolished fragments from zirconium-lined reaction vessels used in corrosive chemical production, with hafnium content under 1:500. The material is heavily corroded and disassembled, classifying it as waste and scrap under tariff item 8109.31.00, not as articles.
8109.31.00Zirconium Extrusion Scrap Billets
Rejected extrusion billets from zirconium tube production, with hafnium content below 1:500. The billets have surface defects that make them unusable for further processing, classifying them as waste and scrap under tariff item 8109.31.00.
8109.31.00Zirconium Foil Trimmings
Edge trimmings from zirconium foil rolling for electronics, with hafnium content compliant with the 1:500 ratio. These trimmings are waste and scrap under tariff item 8109.31.00 because they are offcuts not usable as foil.
8109.31.00Zirconium Heat Exchanger Scrap
Scrap from failed plate heat exchangers in petrochemical plants, made of low-hafnium zirconium sheets and tubes. The material is pitted and has weld failures, making it non-repairable and classifying it as waste and scrap under tariff item 8109.31.00.
8109.31.00Zirconium Powder Press Scrap
Reject pressed shapes from zirconium powder metallurgy, with low hafnium content. These are waste and scrap under tariff item 8109.31.00 because they failed quality control and are not usable as articles.
8109.31.00Zirconium Scrap from Nuclear Reactor Components
Waste zirconium material recovered from decommissioned nuclear fuel cladding, containing less than 1 part hafnium per 500 parts zirconium by weight. This is classified as waste and scrap under tariff item 8109.31.00 due to its non-usable state after decommissioning.
8109.31.00Zirconium Welding Rod Waste
Overrun and defective welding rods from nuclear fabricators, with low hafnium content per the 1:500 ratio. These are waste and scrap under tariff item 8109.31.00 because they are quality rejects and not usable as welding rods.
