Subheadings
Products classified under Tariff item 8103.30.00
Rejected Tantalum Ingots
Off-specification tantalum ingots from electron beam melting, exhibiting cracks or impurities, are destined for remelting. These ingots are not usable as finished articles due to their defects, qualifying them as waste and scrap under tariff item 8103.30.00.
Spent Tantalum Sputtering Targets
Spent tantalum sputtering targets, depleted after use in semiconductor thin-film deposition, are no longer viable for their original purpose. Their eroded and contaminated state renders them unusable as targets, qualifying them as waste and scrap under tariff item 8103.30.00.
Tantalum Chemical Reactor Scrap
Corroded sections removed from tantalum-lined chemical reactors, exposed to aggressive acids, are no longer usable in their original form. This heavy scrap is definitively not usable as reactor components, qualifying as waste and scrap under tariff item 8103.30.00.
Tantalum Electrolyte Anode Scrap
Spent basket anodes from tantalum anodizing processes for capacitor leadwires, heavily pitted from use, are no longer functional. These anodes are definitively not usable as such due to wear, qualifying as waste and scrap under tariff item 8103.30.00.
Tantalum Evaporation Boat Scrap
Deformed and spent tantalum boats used for vacuum evaporation of metals in thin film coating are no longer usable for their intended purpose. Their deformation and contamination render them waste and scrap under tariff item 8103.30.00.
Tantalum Foil Trimmings
Edge trimmings and offcuts from tantalum foil used in chemical processing equipment are generated during sheet fabrication. These trimmings are high-purity tantalum but are not usable as foil, qualifying as waste and scrap under tariff item 8103.30.00.
Tantalum Furnace Linings Scrap
Eroded tantalum fragments from high-temperature vacuum furnace crucibles used in superalloy production are no longer usable as crucibles. Their erosion and structural degradation qualify them as waste and scrap under tariff item 8103.30.00.
Tantalum Implant Manufacturing Scrap
Precision-machined waste from tantalum orthopedic screws and plates production, including sprues and flashings, is generated during manufacturing. This material is not usable as medical devices, qualifying as waste and scrap under tariff item 8103.30.00.
Tantalum Machining Turnings
Fine curls and chips of tantalum produced from lathe and milling operations on tantalum rods or sheets for aerospace components are typical machining waste. These turnings are not usable as components, qualifying as waste and scrap under tariff item 8103.30.00.
Tantalum Powder Waste
Oversized or contaminated tantalum powder from atomization processes for additive manufacturing feedstock is not usable for its intended purpose. This powder is waste and scrap under tariff item 8103.30.00, as it fails to meet specifications.
Tantalum Scrap from Capacitor Manufacturing
Waste tantalum material from electrolytic capacitor production, including shavings, clippings, and rejected components containing at least 99% tantalum by weight, is generated during manufacturing. This material is not usable as capacitors, qualifying as waste and scrap under tariff item 8103.30.00.
Tantalum Sheet Clippings
Irregular clippings from tantalum sheets cut for corrosion-resistant heat exchangers in chemical plants are generated during fabrication. These clippings are not usable as sheet, qualifying as waste and scrap under tariff item 8103.30.00.
Tantalum Superalloy Pour Scrap
Overflow and chill scrap from tantalum-containing superalloy investment casting for turbine blades, with segregated tantalum-rich portions, is generated during casting. This scrap is not usable as turbine blades, qualifying as waste and scrap under tariff item 8103.30.00 if it meets the definition.
Tantalum Wire Scrap
Short lengths and tangled remnants of tantalum wire from medical implant production are recoverable for remelting. These remnants are not usable as wire, qualifying as waste and scrap under tariff item 8103.30.00.
