Subheadings
Products classified under Tariff item 8101.97.00
Tungsten Alloy Turning Scrap
Machining turnings and borings from high-density tungsten alloy parts used in aerospace and defense. These are waste and scrap of tungsten, as the alloy is predominantly tungsten by weight, and the material is not usable as-is.
Tungsten Carbide Scrap
Discarded tungsten carbide inserts and tooling bits from machining operations. Tungsten carbide is a cermet, but as waste and scrap, it is classified under tungsten waste and scrap, not as a separate article.
Tungsten Crucible Scrap
Broken or worn crucibles from high-temperature metallurgy and semiconductor production. These are tungsten articles that are no longer usable, qualifying as waste and scrap under this tariff item.
Tungsten Electrode Scrap
Discarded tungsten electrodes from TIG welding operations, often with minor wear. These are waste and scrap of tungsten, as they are no longer usable as electrodes.
Tungsten Heat Sink Scrap
Scrap from machined tungsten-copper composite heat sinks for power electronics. If tungsten predominates by weight, this is classified as tungsten waste and scrap.
Tungsten Lamp Filament Scrap
Scrap filaments recovered from spent incandescent and halogen lamps. These are tungsten waste and scrap, not lamp parts, as they are no longer usable.
Tungsten Powder Mill Scale Scrap
Oversized particles and dust collected from tungsten powder milling for metallurgy. Despite the powder-like form, these are treated as waste and scrap under this tariff item.
Tungsten Radiation Shielding Scrap
Discarded high-density tungsten alloy plates from medical imaging and nuclear shielding. These are waste and scrap of tungsten articles, as they are no longer usable.
Tungsten Sheet and Foil Scrap
Trimmings and rejects from tungsten sheet used in electronics and heat shields. These are waste from articles of tungsten, classified under this tariff item.
Tungsten Wire Scrap
Waste tungsten wire trimmings and rejects from electrical filament and lamp manufacturing. These are waste and scrap of tungsten, separate from bars, rods, or profiles.
