2803.00.00 - Carbon (carbon blacks and other forms of carbon not elsewhere specified or included)

This HTS category, 2803.00.00, encompasses various forms of carbon that are not specifically classified elsewhere in the Harmonized Tariff Schedule. It primarily includes carbon blacks, which are finely divided forms of amorphous carbon produced by the incomplete combustion or thermal decomposition of hydrocarbons. This category also covers other elemental carbon products not meeting the definitions of more specific headings, such as graphite in certain forms or activated carbon if not otherwise classified under Chapter 38.

Distinguishing this category from its siblings at the root level of the HTS is straightforward, as those relate to entirely different product groups, such as live animals (Chapters 01). Within Section VI, which covers products of the chemical or allied industries, Chapter 28 specifically addresses inorganic chemicals. Therefore, the products under 2803.00.00 are distinct due to their elemental carbon nature and their primary use, often as pigments, reinforcing agents, or additives in various industrial applications.

The subcategories for 2803.00.00 further refine the classification based on the specific type of carbon. "Carbon black" (2803.00.00.10) accounts for the vast majority of goods falling under this heading, differentiated by its production method and particle size. The residual category, "Other" (2803.00.00.50), is intended for any other forms of elemental carbon not specifically designated as carbon black and not elsewhere specified or included in other HTS headings. This subdivision ensures that all forms of elemental carbon are appropriately accounted for within the tariff system.
