Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If misdeclared as simple cyclic alcohol ester
Cyclic alcohols esters are 2902, but aldehyde function and carboxylic acid derivation place it later in 2918.
If polycarboxylic acid derivative
Aromatic polycarboxylic acids go to 2917, but single chain with aldehyde specifies 2918.30.
If fertilizer additive form
Chapter 29 excludes mineral/chemical fertilizers of Chapter 31.
