Products classified under HTS 8103.30.00.00
Tantalum Chemical Reactor Scrap
Corroded sections removed from tantalum-lined chemical reactors exposed to aggressive acids. This heavy scrap qualifies as HTS 8103.30.00.00 tantalum waste.
Tantalum Evaporation Boat Scrap
Deformed and spent tantalum boats used for vacuum evaporation of metals in thin film coating. Classified as tantalum waste and scrap HTS 8103.30.00.00.
Tantalum Implant Manufacturing Scrap
Precision-machined waste from tantalum orthopedic screws and plates production, including sprues and flashings. HTS 8103.30.00.00 for medical-grade tantalum scrap.
Tantalum Etching Residue
Particulate tantalum residue recovered from chemical etching baths in circuit board fabrication. This wet scrap dries to powder form, classified as HTS 8103.30.00.00 waste.
Tantalum Furnace Linings Scrap
Eroded tantalum fragments from high-temperature vacuum furnace crucibles used in superalloy production. Recovered as waste and scrap under HTS 8103.30.00.00.
Tantalum Scrap from Capacitor Manufacturing
Waste tantalum material generated during the production of electrolytic capacitors, consisting of shavings, clippings, and rejected components containing at least 99% tantalum by weight. Classified under HTS 8103.30.00.00 as tantalum waste and scrap due to its unprocessed form unfit for direct use.
Tantalum Machining Turnings
Fine curls and chips of tantalum produced from lathe and milling operations on tantalum rods or sheets for aerospace components. This waste and scrap is classified under HTS 8103.30.00.00 as it meets the criteria for tantalum scrap unfit for immediate fabrication.
Tantalum Foil Trimmings
Edge trimmings and offcuts from tantalum foil used in chemical processing equipment, containing high-purity tantalum. Falls under HTS 8103.30.00.00 as waste and scrap generated during sheet fabrication.
Spent Tantalum Sputtering Targets
Depleted tantalum discs used in semiconductor thin-film deposition, no longer viable for sputtering after erosion. Classified as tantalum waste and scrap under HTS 8103.30.00.00.
Tantalum Wire Scrap
Short lengths and tangled remnants of tantalum wire from medical implant production, recoverable for remelting. HTS 8103.30.00.00 covers this as tantalum waste and scrap.
Tantalum Sheet Clippings
Irregular clippings from tantalum sheets cut for corrosion-resistant heat exchangers in chemical plants. This material is tantalum waste and scrap per HTS 8103.30.00.00.
Tantalum Powder Waste
Oversized or contaminated tantalum powder from atomization processes for additive manufacturing feedstock. Classified under HTS 8103.30.00.00 as waste and scrap.
Rejected Tantalum Ingots
Off-specification tantalum ingots from electron beam melting, cracked or impure, destined for remelting. HTS 8103.30.00.00 applies to such manufacturing scrap.
Tantalum Superalloy Pour Scrap
Overflow and chill scrap from tantalum-containing superalloy investment casting for turbine blades. Segregated tantalum-rich portions as HTS 8103.30.00.00 scrap.
Tantalum Electrolyte Anode Scrap
Spent basket anodes from tantalum anodizing processes for capacitor leadwires, heavily pitted. Recovered as waste and scrap under HTS 8103.30.00.00.
