2917.14.50.00 - Other 🖩

This HTS category, 2917.14.50.00, encompasses "Other" maleic anhydride derivatives that do not fall under the specifically enumerated sibling category. It serves as a residual classification for maleic anhydride derivatives that possess acyclic polycarboxylic acid structures but lack the specific derivation from benzene or other aromatic hydrocarbons specified elsewhere at this level. The scope of this classification is broad, covering various chemical modifications or forms of maleic anhydride that are not otherwise categorized.

The key distinction of this category from its sibling, 2917.14.10.00, lies in the origin of the precursor materials. While 2917.14.10.00 specifically targets maleic anhydride derivatives synthesized from benzene or other aromatic hydrocarbons, this category is for those not meeting that specific aromatic origin criterion. This classification therefore applies to maleic anhydride derivatives that might be produced through alternative synthetic pathways or from non-aromatic feedstocks, as long as they maintain the structural characteristics of acyclic polycarboxylic acid derivatives.

As this node is a leaf node within the HTS structure, there are no further subcategories. Therefore, the practical application of this classification relies on a careful analysis of the chemical composition and origin of the product to ensure it does not qualify for a more specific, preceding HTS code and also does not meet the criteria for the specified sibling category. Examples could include certain unsaturated polyester resins or other chemical intermediates where maleic anhydride is a key component but the manufacturing process does not involve aromatic hydrocarbon precursors.
