2915.90.14.00 - Valproic acid

This classification covers valproic acid, a saturated acyclic monocarboxylic acid. It falls under the broader category of "Other" monocarboxylic acids and their derivatives, specifically within the subcategory for "Acids." This means it is a specific chemical compound identified by its unique structure and properties, and it is not a salt, ester, or other derivative of valproic acid, nor is it a mixed product containing valproic acid as a primary component.

The distinction between this specific HTS code and its sibling, 2915.90.18 ("Other"), lies in the precise identification of the chemical substance. While 2915.90.18 would capture other miscellaneous saturated acyclic monocarboxylic acids and their derivatives not specifically enumerated elsewhere, this node is dedicated solely to valproic acid. Classification here is determined by the presence and chemical identity of valproic acid as the principal constituent, based on analytical testing and documentation.

As this is a leaf node, there are no further subcategories. The classification of valproic acid terminates at this level, meaning all forms and purities of valproic acid, when imported as the pure chemical substance, will be classified under 2915.90.14.00. This ensures a consistent and specific classification for this particular organic chemical.
