Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in ribbon or foil form for deposition
Thin foil-like tungsten classifies as 'other articles,' not round wire.
If gold-plated for bonding
Plated micro-wire for electronics falls under Chapter 85 fitted electrical conductors.
If as chemical vapor deposition precursor wire
Wire used in thin-film deposition processes may classify as chemical elements/plates.

Import Tips & Compliance
• Provide SEM images or specs for wire diameter to confirm micro-wire status
• Avoid classification as sputter target material under 8101.99 if in ribbon form
• Declare cleanroom packaging to prevent contamination claims during customs

Tungsten Filament Wire
Thin tungsten wire used primarily as filaments in incandescent light bulbs and halogen lamps. It falls under HTS 8101.96.00.00 as it is wire made from tungsten (wolfram), distinct from rods or bars.
Tungsten EDM Wire
High-precision tungsten wire for electrical discharge machining (EDM), valued for its high melting point and conductivity. Classified under HTS 8101.96.00.00 specifically as tungsten wire, separate from coated or profiled variants.
Tungsten Thermocouple Wire
Tungsten-rhenium alloy wire used in Type C thermocouples for high-temperature measurement up to 2300°C. Though alloyed, if tungsten-dominant (>99% per note exclusion), it fits HTS 8101.96.00.00 as tungsten wire.
