Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically maleic anhydride-derived
Certain production methods trigger specific subheading within fumaric acid.
If pre-polymerized into unsaturated polyester resins
Polymerized forms shift to Chapter 39 plastics heading.
If optical isomers (L- or D-fumaric acid)
Stereoisomers may fall under general acyclic polycarboxylic acids.

Import Tips & Compliance
• Provide particle size distribution data to distinguish from food-grade fine powders
• Declare exact CAS number (110-17-8) and purity to avoid mixture classification
• Watch for anti-dumping duties if sourced from certain Asian manufacturers
