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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If diameter exceeds typical wire gauge (e.g., >5mm)
Thicker tungsten products classify as bars or rods, not wire, per tariff distinctions in heading 8101.
If coated with flux for welding electrodes
Flux-coated tungsten wire becomes a welding electrode preparation under Chapter 83, changing from unwrought articles.
If it's a tungsten-copper alloy wire
Alloys with <99% tungsten content classify under copper or other base metals, not pure tungsten in Chapter 81.

Import Tips & Compliance
• Verify tungsten purity exceeds 99% by weight to confirm classification under Chapter 81; alloys shift to other base metal headings
• Provide mill test certificates documenting chemical composition and mechanical properties to avoid misclassification as scrap
• Ensure wire diameter and tolerance specs match 'wire' definition, as thicker forms may classify as bars under 8101.94
