2707.99.90 - Other

This HTS category, 2707.99.90, encompasses "Other" products derived from the distillation of high-temperature coal tar, where the weight of aromatic constituents surpasses that of non-aromatic ones. It serves as a residual category for such products that do not fit into the more specifically defined subcategories of 2707.99.

While sibling categories at this level (2707.99.10, 2707.99.20, 2707.99.40, and the phenols group) account for distinct classes like light oil, picolines, carbazole, and phenols, this particular "Other" designation captures any remaining aromatic-rich coal tar distillation products that don't meet the specific criteria for those other classifications. It is crucial to analyze the precise chemical composition and intended use to differentiate these products from those specifically enumerated under preceding subheadings.

Within this category, further subdivisions exist to refine the classification of these residual products. The subcategories 2707.99.90.10 and 2707.99.90.90 distinguish between carbon black feedstocks and other remaining "other" substances, respectively. This allows for a more granular accounting of the diverse range of products that fall under the broad umbrella of aromatic-rich coal tar distillates not otherwise specified.
