N-Ethylethylenediamine
N-Ethylethylenediamine is a derivative of ethylenediamine with one amine group mono-substituted by ethyl (H2NCH2CH2NHCH2CH3), remaining an acyclic polyamine. Classified under HTS 2921.21.00.00 as it retains the essential ethylenediamine structure with minimal derivatization.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If di-substituted forming symmetrical diethyl derivative
Higher alkyl substitution moves to other acyclic monoamines or polyamine derivatives in 2921.19.
If cyclic polymerized form used as epoxy curing agent
Polymerized/cyclized derivatives excluded from acyclic polyamines, moving to heterocyclic compounds.

Import Tips & Compliance
• Submit NMR/GC assay confirming >95% purity and ethyl substitution pattern to validate polyamine heading
• Classify as UN 2922 (corrosive liquid, flammable) requiring steel drums with UN certification for ocean transport
• Watch for reclassification if ethyl content >50% shifts material to monoamine-dominant structures
