Overview
Category 2936 encompasses a broad range of provitamins and vitamins, whether naturally occurring or synthetically produced, along with their natural concentrates and derivatives. This classification also includes mixtures of these substances, regardless of whether they are dissolved in a solvent. The key defining characteristic is their primary use as vitamins, intended for nutritional supplementation or as active pharmaceutical ingredients.
This category is distinct from its siblings within Section VI, which cover a diverse array of chemical products, and specifically from other organic chemicals in Chapter 29. Unlike raw materials or intermediate chemical compounds, goods classified under 2936 are recognized for their specific biological function as vitamins. For instance, while certain organic compounds might be precursors to vitamins, they would only fall under 2936 if they are explicitly provitamins or derivatives used *primarily* as vitamins.
Subdivision within 2936 allows for further specificity. The primary subcategory addresses vitamins and their derivatives when they are presented in an unmixed form. This distinction is crucial for accurate duty assessment and trade statistics. Any remaining items, including provitamins and natural vitamin concentrates that do not fit into the "unmixed" subcategory, or specific intermixtures, are classified under the "Other" designation, ensuring comprehensive coverage of all relevant vitamin-related products.
