Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as a derivative salt like diethylenetriamine hydrochloride
Salts of acyclic polyamines are classified under 2921.30 per chapter note on salts following the base compound.
If imported as aqueous solution exceeding transport-only concentrations
Solutions not solely for safety/transport fall outside Chapter 29 per note 2(e) into mixtures of Chapter 38.
If put up in measured doses as pharmaceutical intermediate
Organic compounds prepared for medicinal use shift to Chapter 29 heading 2942.

Import Tips & Compliance
• Provide certificate of analysis confirming purity >98% to verify classification as chemically defined compound under Chapter 29
• Ensure proper hazardous material declaration (UN2051, Corrosive) for DOT/IMDG compliance during import
• Avoid misclassification as mixtures; single-compound DETA must not exceed 1% impurities per chapter notes
