2936.29.50.30 - Biotin

This category encompasses Biotin, a specific vitamin classified under provitamins and vitamins and their derivatives. Biotin, also known as Vitamin B7 or Vitamin H, is a water-soluble vitamin essential for various metabolic processes, including fatty acid synthesis, amino acid metabolism, and carbohydrate metabolism. It is primarily used for its nutritional and health benefits and is found in a wide range of food sources and dietary supplements.

This specific subcategory, 2936.29.50.30, is distinguished from its sibling category, 2936.29.50.20, which specifically covers Vitamins D and their derivatives. While both fall under "Other vitamins and their derivatives," this classification is reserved solely for Biotin, ensuring its distinct treatment from other vitamin groups. The sibling category 2936.29.50.50, "Other," would encompass any remaining unmixed vitamins and their derivatives not otherwise specified.

As this node represents a leaf node in the HTS classification structure, there are no further subcategories. Therefore, the focus remains on precisely identifying Biotin for import and export purposes, ensuring accurate declaration and adherence to customs regulations. Classification at this level relies on the precise identification of the chemical compound itself, Biotin, as a distinct and recognized vitamin.
