Products classified under HTS 8109.31.00.00
Low-Hafnium Zirconium Turning Scrap
Machining turnings and chips from zirconium alloy aerospace parts, with hafnium below 1:500 ratio by weight. Falls under HTS 8109.31.00.00 as zirconium waste and scrap, distinct from wrought articles due to fragmented, contaminated state requiring remelting.
Zirconium Heat Exchanger Scrap
Scrap from failed plate heat exchangers in petrochemical plants, low hafnium zirconium sheets and tubes. HTS 8109.31.00.00 as waste due to pitting and weld failures rendering it non-repairable.
Pharmaceutical Reactor Zirconium Scrap
Cuttings and offcuts from zirconium vessels in pharma API synthesis, hafnium-compliant for 8109.31.00.00. Classified as scrap for its fabrication waste nature.
Zirconium Welding Rod Waste
Overrun and defective welding rods from nuclear fabricators, low hafnium per HTS 8109.31.00.00. Waste status from quality rejects.
Test Sample Zirconium Clippings
Small clippings from quality control tests on zirconium sheets for medical implants, under hafnium limit. HTS 8109.31.00.00 as lab-generated scrap.
Zirconium Extrusion Scrap Billets
Rejected extrusion billets from tube production, hafnium <1:500. Scrap under 8109.31.00.00 due to surface defects.
Naval Zirconium Propeller Scrap
Scrap from corroded zirconium propeller shafts in submarines, low hafnium. 8109.31.00.00 for military surplus scrap.
Zirconium Foil Trimmings
Edge trimmings from zirconium foil rolling for electronics, hafnium compliant. Scrap per 8109.31.00.00.
Lab Equipment Zirconium Scrap
Broken crucibles and boats from analytical labs, low hafnium zirconium. Waste under HTS 8109.31.00.00.
Zirconium Powder Press Scrap
Reject pressed shapes from powder metallurgy, hafnium low. Scrap classification 8109.31.00.00.
Salt Bath Furnace Liners Scrap
Degraded zirconium liners from heat treating furnaces, low hafnium. HTS 8109.31.00.00 scrap.
Zirconium Anode Scrap
Spent sacrificial anodes from electroplating tanks, hafnium <1:500. Waste/scrap 8109.31.00.00.
Zirconium 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. Classified under HTS 8109.31.00.00 as zirconium waste and scrap due to its low hafnium content and unsuitability for direct reuse without refining. This scrap is commonly recycled for new zirconium alloy production.
Zirconium Chemical Processing Vessel Scrap
Demolished fragments from zirconium-lined reaction vessels used in corrosive chemical production, hafnium content under 1:500. HTS 8109.31.00.00 covers this as waste and scrap, not articles, due to heavy corrosion and disassembly.
Aerospace Zirconium Alloy Borings
Fine borings from drilling zirconium components for aircraft engines, strictly low hafnium per 8109.31.00.00 specs. As waste and scrap, it's valued for remelting into high-purity alloys.
