Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not halogenated/sulfonated/nitrated/nitrosated
Parent aromatic ketones without reactive group modifications fall under the non-derivatized subheading.
If primarily used as pharmaceutical intermediate
Certain heterocyclic derivatives or hormone precursors may shift to Chapter 29 subchapter for specific uses.
If imported as mixture with solvents exceeding transport tolerances
Solutions beyond safety/transport exceptions per chapter note (e) classify as chemical preparations.

Import Tips & Compliance
• Provide detailed chemical analysis (NMR, GC-MS) confirming aromatic structure and halogenation to avoid reclassification
• Ensure SDS and purity certificates; impurities may trigger review under chapter note (a)
• Verify not excluded under chapter note (g) if containing colorants beyond identification purposes
