Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when produced via butane/butene catalytic air oxidation
Petrochemical process changes derivation source from aromatic hydrocarbons.
If heterocyclic oxygen compounds containing anhydride groups
Structural changes creating heterocyclic rings shift to different chapter heading.
If imported as unsaturated polyester resin containing >50% maleic anhydride
Polymerized forms classified as plastics rather than chemical monomers.

Import Tips & Compliance
• Include GC-MS analysis confirming <0.5% maleic acid content for pure anhydride classification
• Declare proper flash point (104°C) and autoignition temperature on shipping papers
• Monitor for fumaric acid impurities that could affect duty classification
