Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ester of a non-enumerated phenolic acid
Esters classify with the latest numerical parent, but non-listed acids go to residual.
If classified primarily as an ether rather than ester
Ether function might take precedence if not clearly carboxylic ester per oxygen function notes.

Import Tips & Compliance
• Confirm ester linkage via spectroscopic data; ethyl esters would follow note 3(A)(B) but phenyl follows parent; avoid solvent solutions unless for safety per note (e)
