Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If acylated or containing amino-acid functions
Amine-function compounds with added oxygen-functions from Chapter 29 notes classify in later headings like 2922.
If pesticide-grade with biocidal additives
Herbicide or plant growth regulator formulations containing TEPA shift to Chapter 38 pesticide headings.
If ethyl alcohol esters present
Esters of polyamines with ethanol follow acid-function classification rules per Chapter 29 note on esters.

Import Tips & Compliance
• Include distillation process certificates and GC-MS analysis to confirm chemical identity and purity
• Verify no added functional groups that would reclassify under oxygen-function amine headings like 2922
• Package in UN-approved drums; declare exact stabilizer content to comply with Chapter 29 note (f)
