Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If quaternized to permanent cation
Quaternary ammonium salts shift to Chapter 29 nitrogen-function compounds outside amino-alcohols.
If complexed with heavy metals
Organometallic derivatives classify later in Chapter 28 per coordination compound rules.
If technical grade with >5% impurities
Technical mixtures not meeting 'chemically defined' criteria of Chapter 29 note (a) classify in 3824.

Import Tips & Compliance
• Specify counterion (HCl) and protonation evidence via NMR/IR spectra in technical documentation
• White crystalline form distinguishes from liquid free base; include melting point (100-110°C)
• TSCA inventory verification mandatory; pre-register if novel salt form for US market
