2936.90.01.10 - Provitamins

This HTS category, 2936.90.01.10, specifically encompasses provitamins. Provitamins are compounds that the body can convert into vitamins. This classification includes substances that are not themselves vitamins but serve as precursors, fulfilling a vital role in nutritional supplements and pharmaceutical preparations. Examples within this category might include beta-carotene, which the body converts to Vitamin A, or ergocalciferol precursors.

This specific subheading distinguishes itself from its sibling, 2936.90.01.50, which covers "Other" items within the broader "Other, including provitamins and natural concentrates" grouping. While both fall under the same parent category, 2936.90.01.10 is dedicated solely to provitamins, whereas 2936.90.01.50 would likely capture other non-vitaminous substances or mixtures not specifically itemized elsewhere within the provitamin and vitamin heading. The key distinction lies in the direct precursor relationship to a vitamin for the goods classified under 2936.90.01.10.

As a leaf node, this category does not have further subdivisions. Therefore, the focus for classification under 2936.90.01.10 rests on accurately identifying the substance as a provitamin, meaning it is capable of being converted into a vitamin by biological processes, and is not itself an active vitamin or a vitamin concentrate. The classification hinges on the chemical structure and the inherent biological function of the imported material as a provitamin.
