2849.90.30.00 - Of tungsten

This HTS category, 2849.90.30.00, specifically classifies carbides that are composed of tungsten, whether or not they have undergone specific chemical definition. Tungsten carbides are known for their exceptional hardness, wear resistance, and high melting point, making them valuable in various industrial applications. This classification applies to pure tungsten carbides as well as compounds where tungsten is the primary constituent element of the carbide.

This category is distinct from its siblings, 2849.90.10.00 (Of boron) and 2849.90.20.00 (Of chromium), as it exclusively covers carbides where tungsten is the defining metallic element. The sibling category 2849.90.50.00 (Other) would encompass carbides of metals not explicitly listed in the preceding subcategories, such as silicon carbide or titanium carbide, differentiating it from the specialized tungsten carbide classification.

As a leaf node, there are no further subcategories under 2849.90.30.00. Classification at this level is determined by the presence of tungsten as the key component of the carbide. Examples include tungsten carbide powders, sintered tungsten carbide articles (before further working into tools or machinery parts), and chemical compounds where tungsten carbide is the primary constituent, provided they are not specifically covered under a more precise HTS heading for finished goods.
