Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed primarily as quaternary ammonium salt precursor
Imine-function compounds take precedence over amine classification per numerical order rule in Chapter 29.
If for pesticide or herbicide formulations containing DETA
Pesticide preparations exclude from Chapter 29 per note 2(k), moving to Chapter 38.
If acetylated derivative like N,N-bis(2-aminoethyl)acetamide
Acetylated amines with oxygen functions classify under earlier 2903 amine headings.
