U.S. imports of tungsten wire (HS 810196) totaled $1.8M in July 2026, traded with 13 countries.
Importers of Tungsten Wire paid $281K in duties in July 2026 — an effective duty rate of 15% on $1.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Tungsten Wire imports of $1.8M in July 2026 ran 37% below the year-to-date monthly average of $2.9M.
Last updated: July 2026 dataDrawn to extremely fine gauges and valued for its high melting point and tensile strength, tungsten wire is a specialized product used in incandescent and halogen lamp filaments, thermocouple supports, and semiconductor manufacturing equipment. India leads US import supply, followed by Japan and China. Fine-gauge tungsten wire is a technically demanding product where diameter tolerance, surface finish, and tensile strength are tightly specified, and suppliers typically provide mill certifications that importers should retain for both quality and customs-classification purposes.

Tungsten wire (8101960000) is distinguished by its circular cross-section and the drawing process used to produce it, typically resulting in diameters from a few micrometers up to several millimeters. Bars and rods with non-circular cross-sections, or those produced by sintering alone, fall under different subheadings. When the cross-section is circular but the diameter is large, the line between 'wire' and 'rod' can be ambiguous — CBP generally looks at the production method and commercial designation.
India has developed a substantial wire-drawing industry that processes imported tungsten intermediate products — such as rods or sintered blanks — into finished wire. This downstream processing capability, combined with competitive labor costs, allows Indian manufacturers to supply fine-gauge wire competitively. Importers should verify that wire processed in India from Chinese-origin intermediates qualifies for Indian origin under CBP's substantial-transformation standard.
