Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is an amino-phenol rather than an amino-ketone
Amino-phenols with one oxygen function fall under heading 2922.29, but the enone structure makes 2922.39 more specific.
If the product is converted to a heterocyclic compound before import
If the product is imported as a flavone or other heterocyclic compound, it would fall under heading 29.33.
