Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the nitro group dominates over amino-alcohol function
Amino-acid nitriles or derivatives prioritize nitrogen functions in 2922.50, but oxygen function rules here per notes.
If pure diol without prominent amino or nitro substitution
Other polyhydric alcohols classify in 2905; amino addition shifts to 2922 oxygen-function amino-compounds.
If esterified form imported
Saturated acyclic monocarboxylic acid esters go to 2915 per note 3(A), classified by later heading.

Import Tips & Compliance
• Include spectroscopic data (NMR, IR) to confirm identity, as nitro groups require note compliance for nitrated derivatives
• Label clearly as research chemical to prevent confusion with finished drugs; ensure no therapeutic claims in documentation
• Check for anti-dumping on nitro compounds; provide origin certificates to avoid penalties
