2917.14.10.00 - Derived in whole or in part from benzene or other aromatic hydrocarbons

This HTS category, 2917.14.10.00, specifically classifies maleic anhydride that is derived in whole or in part from benzene or other aromatic hydrocarbons. Maleic anhydride itself is a dicarboxylic acid anhydride with the formula C4H2O3. Its primary applications include its use as a raw material in the production of unsaturated polyester resins, alkyd resins, and as a comonomer in various polymerization processes. The defining characteristic for this specific classification is the origin of its synthesis, requiring a traceable link to aromatic hydrocarbon precursors.

In contrast to its sibling category, 2917.14.50.00 ("Other"), which broadly covers any maleic anhydride not fitting the criteria of this subheading, 2917.14.10.00 demands a precise origin of manufacture. The "Other" category would encompass maleic anhydride produced from different feedstocks, such as n-butane or benzene derived through non-aromatic routes, where the aromatic hydrocarbon link is absent or not the primary source. Therefore, careful consideration of the manufacturing process and starting materials is crucial for correct classification.

As this is a leaf node within the HTS structure, there are no further subcategories for maleic anhydride derived from benzene or other aromatic hydrocarbons. Classification at this level is final, and shipments falling under 2917.14.10.00 are not subject to further subdivision. Importers and exporters must be prepared to provide documentation verifying the aromatic hydrocarbon origin to support the classification under this specific code.
