2906.13.50.00 - Other

This HTS code, 2906.13.50.00, falls under the broader category of "Sterols and inositols," specifically encompassing "Other" cyclanic, cyclenic, or cycloterpenic alcohols and their derivatives. It serves as a residual classification for sterols and inositols that do not fit into more specific subcategories within this group. This includes a wide array of complex cyclic alcohol compounds with distinct biological roles and chemical structures, primarily derived from plants and animals, or synthesized.

It is crucial to distinguish this category from its sibling, 2906.13.10.00, which specifically covers "Inositols." While both fall under sterols and inositols, this "Other" category is intended for sterols and any other related cyclanic, cyclenic, or cycloterpenic alcohols and their derivatives that are not inositols. The classification will depend on the precise chemical structure and identification of the compound in question.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, proper classification within 2906.13.50.00 relies heavily on the definitive identification of the chemical substance as a sterol or a related cyclanic, cyclenic, or cycloterpenic alcohol derivative, and its exclusion from the more specifically defined "Inositols" category. Import and export declarations should accurately identify the specific chemical compound to ensure correct tariff application.
