Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as hydrochloride salt
Salts of oxygen-function amino-compounds classified with parent compound per chapter note, but aromatic amine salts may shift to 2924 if nitrogen-function predominates.
If for industrial dye manufacturing use
If specifically prepared and put up for dye production, may fall under heterocyclic compounds in 2933 per exclusions.
If considered derivative of ketone without prominent amino function
Material composition emphasis on sulfonated/nitrated ketone derivatives could reclassify under earlier oxygen-function headings.

Import Tips & Compliance
• Verify purity certificate and CAS number (122-80-5) match import declaration; ensure SDS includes handling for sensitizing properties
• Common pitfall: misclassifying as non-aromatic if ring substitution unclear
• Register with CBP for note 3 chemicals if volume exceeds thresholds
