Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If deemed 'other' saturated acyclic ester
Non-aromatic propionic esters go to 2915.90; disputes over phenyl ring impact arise without proof.
If for paint/lacquer solvent use
Flavor/fragrance esters lose Chapter 29 status if primarily chemical prep for specific industry.
If sugar ester derivative
Sugar esters of propionic derivatives fall to 2940 per Chapter note (c).

Import Tips & Compliance
• Label with exact IUPAC name and structure diagram; customs often challenges aromatic vs aliphatic distinction
• Ship with stabilizer disclosure; anti-dusting agents allowed only if not rendering specific-use per note (g)
• Avoid bulk packaging mimicking mixtures—separate pure compound to prevent 3824 shift
