2936.29.20.00 - Aromatic or modified aromatic

This HTS category, 2936.29.20.00, encompasses provitamins and vitamins, both natural and synthetically produced, along with their derivatives primarily used as vitamins. This includes any mixtures of these substances, regardless of whether they are dissolved in a solvent. The scope extends to natural vitamin concentrates.

The distinguishing factor for this specific subcategory lies in its inclusion of "aromatic or modified aromatic" vitamins and their derivatives, which are not explicitly covered by other more specific sub-classifications within the broader "Vitamins and their derivatives, unmixed: Other vitamins and their derivatives: Other" heading.

As this is a leaf node, there are no further subdivisions. Therefore, classification under this code is determined by the presence of aromatic or modified aromatic structures in the vitamin or provitamin, provided it meets the general definition of the parent categories. Examples would include specific synthetic vitamin derivatives exhibiting aromatic ring structures that are not classified elsewhere.
