Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stabilizer (acetic acid) dominates character
If addition renders it an acetate ester, Chapter note on esters classifies to later numerical heading.
If stabilizer added for specific use beyond transport
Chapter note (g) excludes if additions make suitable for specific use.
If forms aromatic carboxylic acid derivative
Salts of aromatic acids could shift if acetic acid salt predominates.
