Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coated or covered
Coated tungsten wire falls under subheading 8101.97, while uncoated plain wire remains in 8101.96.
If imported as interchangeable tool for EDM machines
Wire designed as a consumable tool part may classify under Chapter 82 tools rather than base metal articles.
If for tungsten-rhenium alloy EDM wire
Alloyed wire with significant rhenium content (<99% tungsten) moves out of Chapter 81 to copper alloys.

Import Tips & Compliance
• Include technical datasheets specifying tensile strength and diameter to distinguish from rod forms
• Check for any coatings; uncoated wire stays in 8101.96, but coated may shift to 8101.97
• Declare intended use as EDM to preempt scrutiny, but note classification is material-based, not end-use

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 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.
Pure Tungsten Lamp Wire
99.95% pure tungsten wire drawn for use in specialty lighting filaments, offering superior durability. It is explicitly 'wire' under HTS 8101.96.00.00 within tungsten articles.
Tungsten Welding Wire
Straight or coiled tungsten wire for TIG welding electrodes, prized for arc stability. Classified as plain wire under HTS 8101.96.00.00 before any electrode processing.
