Products classified under Tariff item 8101.96
Pure Tungsten Lamp Wire
Pure tungsten lamp wire, drawn to 99.95% purity, is used in specialty lighting filaments where high melting point and durability are essential. It qualifies as tungsten wire under tariff item 8101.96.00, being a drawn product of uniform solid cross-section, not further worked into articles.
8101.96.00Tungsten EDM Wire
Tungsten EDM wire is a high-precision, drawn tungsten wire used in electrical discharge machining, valued for its high melting point and electrical conductivity. It falls under tariff item 8101.96.00 as tungsten wire, provided it is not coated or otherwise processed beyond drawing.
8101.96.00Tungsten Filament Wire
Tungsten filament wire is thin, drawn tungsten wire used as filaments in incandescent and halogen lamps. It is classified under tariff item 8101.96.00 as tungsten wire, distinct from rods or bars, and is not yet formed into finished filaments.
8101.96.00Tungsten Heating Element Wire
Tungsten heating element wire is resistive tungsten wire designed for industrial furnace heating coils, capable of operating up to 3000°C. It qualifies as tungsten wire under tariff item 8101.96.00, being a drawn product of uniform cross-section, not yet formed into heating elements.
8101.96.00Tungsten Medical X-Ray Wire
Tungsten medical X-ray wire is high-density tungsten wire used for X-ray tube anodes and targets in medical imaging. It is classified as tungsten wire under tariff item 8101.96.00 before machining into targets or anodes.
8101.96.00Tungsten Microelectronics Wire
Tungsten microelectronics wire is ultra-fine tungsten wire, down to 10μm, used for bonding in semiconductor packaging. It falls under tariff item 8101.96.00 as tungsten wire, provided it is not coated or processed beyond drawing.
8101.96.00Tungsten Thermocouple Wire
Tungsten thermocouple wire is a tungsten-rhenium alloy wire used in Type C thermocouples for high-temperature measurement up to 2300°C. It is classified under tariff item 8101.96.00 as tungsten wire, as tungsten predominates by weight and the alloy is treated as tungsten under section note 5.
8101.96.00Tungsten Welding Wire
Tungsten welding wire is straight or coiled tungsten wire used for TIG welding electrodes, prized for arc stability. It is classified as tungsten wire under tariff item 8101.96.00 before any electrode processing, such as grinding or doping.
