Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If simple aromatic ketone without acetic acid chain
Other aromatic ketones fall under 2918.21, but phenylacetic structure with formyl makes this specific ester classification.
If with added stabilizer exceeding Chapter 29 incidental limits
Excess stabilizers make it a preparation of Chapter 38 rather than pure compound with necessary preservative.
If organo-metallic derivative
Organo-inorganic compounds with metals linked to carbon go to 2931 per chapter notes.
