8101.10.00.00 - Powders

This HTS category, 8101.10.00.00, specifically covers tungsten (also known as wolfram) in the form of powders. This designation applies to tungsten material that has been processed into fine granular particles. The particle size and physical form are key determining factors for classification under this subheading, differentiating it from other forms of tungsten.

In contrast to its sibling category, "Other," which would encompass all other forms of tungsten and articles thereof not specifically classified elsewhere, this subheading is dedicated solely to the powdered state of the metal. Therefore, any tungsten product that is not in powder form, such as ingots, bars, wire, or finished articles, would fall under different subheadings within Chapter 81.

As this is a leaf node, there are no further subcategories to subdivide this classification. Classification under 8101.10.00.00 is definitive once the material is confirmed to be tungsten powder. This includes powders intended for various industrial applications, such as in the manufacturing of carbide tools, filaments for incandescent lamps, or as alloying elements.
