2917.19.15.00 - Derived in whole or in part from aromatic hydrocarbons 🖩

This HTS category, 2917.19.15.00, specifically classifies fumaric acid when it is derived in whole or in part from aromatic hydrocarbons. Fumaric acid is an organic compound, a dicarboxylic acid, that serves various industrial purposes, including as a food additive (acidulant and flavoring agent), in the production of resins, and as a precursor in pharmaceutical manufacturing. The key defining characteristic for classification under this subheading is the origin of the fumaric acid, necessitating an examination of its synthesis pathway.

This subheading is distinct from its sibling category, 2917.19.17.00, which covers other acyclic polycarboxylic acids and their derivatives. While both fall under the broader heading of acyclic polycarboxylic acids, the "Other" subheading at 2917.19.17.00 is intended for compounds that do not meet the specific derivational criteria of 2917.19.15.00, meaning fumaric acid not derived from aromatic hydrocarbons, or other acyclic polycarboxylic acids and their related derivatives.

As this is a leaf node, there are no further subcategories to explore within this specific classification. Classification decisions at this level will therefore hinge on definitively establishing whether the fumaric acid in question has an aromatic hydrocarbon origin. This often requires reviewing product specifications, manufacturing process documentation, or laboratory analysis to confirm the presence or absence of aromatic hydrocarbon precursors in its synthesis.
