2936.29.50.20 - Vitamins D and their derivatives

This HTS subcategory, 2936.29.50.20, specifically covers Vitamins D and their derivatives. This includes various forms of Vitamin D, such as Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol), as well as their synthesized or naturally derived forms. The classification applies to these vitamins and their derivatives when they are unmixed and not part of a vitamin intermixture, and are primarily intended for their vitamin properties.

Within the broader category of "Other vitamins and their derivatives," this subcategory differentiates itself from its siblings. For instance, 2936.29.50.30 is exclusively for Biotin, a specific B vitamin. Similarly, 2936.29.50.50 encompasses "Other" vitamins and derivatives not otherwise specified, meaning this 2936.29.50.20 is the designated classification for the Vitamin D family and their immediate derivatives.

As a leaf node, 2936.29.50.20 has no further subcategories. Therefore, classification decisions within this code will rely on the precise identification of the substance as a form of Vitamin D or a derivative thereof, and the absence of mixing with other vitamins or substances. Examples of covered items could include calciferol, calcitriol, and related compounds primarily recognized for their role in calcium metabolism and bone health.
