2936.29 - Other vitamins and their derivatives:

Category 2936.29 encompasses vitamins and their derivatives that are not specifically enumerated under the preceding subheadings within the "Vitamins and their derivatives, unmixed" group. This includes a broad range of essential vitamins and compounds that exhibit vitamin activity but do not fall into the more specific categories like Vitamins A, B1, B2, B5, or B6. The primary defining characteristic is their chemical nature as vitamins or their direct derivatives, intended for human or animal nutrition, or for other industrial uses where their vitamin properties are paramount.

Distinguishing this category from its siblings is crucial for accurate classification. While siblings like 2936.21 (Vitamins A) or 2936.22 (Vitamin B1) address specific, well-defined vitamin families, 2936.29 acts as a residual category for other unmixed vitamins and their derivatives not otherwise specified. This means goods classified here are typically those that have distinct chemical structures from the explicitly listed vitamins and are not covered by more granular headings.

The subcategories within 2936.29 further refine this classification based on specific vitamin types. For instance, 2936.29.10.00 specifically addresses Folic acid (Vitamin B9), while 2936.29.16 covers Niacin and niacinamide (Vitamin B3). The residual "Other" category within this group is for any remaining unmixed vitamins and their derivatives that do not fit into these more specific subdivisions, ensuring a comprehensive classification of all unmixed vitamin products.
