2849.90.20.00 - Of chromium

This HTS category, 2849.90.20.00, specifically classifies carbides that are not chemically defined and are composed of chromium. This includes various forms of chromium carbide, which are inorganic chemical compounds characterized by the presence of chromium and carbon. These materials are typically hard and resistant to heat and wear, finding applications in areas such as cutting tools, wear-resistant coatings, and as a component in advanced ceramics and cermets.

This classification is distinct from its siblings, which cover other specific metallic carbides. For instance, 2849.90.10.00 pertains to boron carbides, while 2849.90.30.00 covers tungsten carbides. The "Other" category at the same level (2849.90.50.00) would encompass carbides of metals not specifically listed elsewhere in this sub-heading. Therefore, the key distinguishing factor for this category is the exclusive presence of chromium as the metallic element within the carbide compound.

As a leaf node, this classification does not have further subdivisions. Classification within this code hinges on the positive identification of the carbide as being *of chromium*. Importers and exporters should ensure that their documentation accurately reflects the elemental composition of the carbide in question to facilitate correct customs processing.
