Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derivative salts thereof
Salts of acyclic polyamines like tetraethylene pentamine derivatives fall under 2921.30 per Chapter 29 note on salt classification.
If imported as a formulated mixture with solvents
Solutions exceeding Chapter 29 note (e) transport limits or rendered suitable for specific uses classify as chemical preparations in Chapter 38.
If ethylenediamine-based with fewer ethylene units
Closely related acyclic monoamines or diamines like ethylenediamine are classified earlier in 2909, but polyamines with 4+ units go to 2921.
