Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nitrogen function (diethylamino) is principal characteristic
Aromatic amines with subordinate ketone groups classify under Chapter 29 nitrogen functions per numerical order rule.
If for bulk industrial ketone use without photoinitiator purity specs
Cyclic ketones like substituted benzophenones go to 2914 if not specifically note 3 compounds.
If when imported for direct use in synthetic dye manufacture
Disperse dyes and preparations put up for specific coloring use exclude from Chapter 29 per note 2(g).

Import Tips & Compliance
• Submit detailed structural formula and NMR/GC purity data to confirm classification over nitrogen-function headings
• Check for TSCA registration; common error is shipping without proper amino compound hazard labeling
• Avoid describing as 'dye intermediate' which could trigger 3204 classification
