Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived primarily from petroleum hydrocarbons
Maleic anhydride from butene oxidation falls under non-aromatic derivation subheading.
If finishing agents containing maleic anhydride >30% by weight
Mixtures for textile finishing classified in Chapter 38 as chemical preparations.
If imported as purified acyclic polycarboxylic acid without anhydride function
Maleic acid (not anhydride) classified under other acyclic polycarboxylic acids.

Import Tips & Compliance
• Verify certificate of analysis confirming aromatic hydrocarbon derivation to meet HTS 2917.14.10.00 specificity
• Ensure proper UN packaging (Group II corrosive) and include Material Safety Data Sheets (MSDS)
• Avoid misclassification as petroleum-derived (2917.14.20.00) which has different duty rates
