Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with solvents or stabilizers exceeding 1% by weight
Solutions or preparations of polyamines not meeting Chapter 29 purity standards fall under prepared chemical mixtures.
If when imported pre-mixed as epoxy curing agent
Adhesives containing triethylenetetramine as principal active ingredient are classified in Chapter 35.
If containing heterocyclic impurities >0.5%
Presence of heterocyclic compounds changes classification from acyclic polyamines to other heterocycles.

Import Tips & Compliance
• Provide detailed chemical analysis certificates confirming purity >98% to avoid reclassification as mixtures under Chapter 38
• Ensure SDS and REACH compliance documentation for hazardous material handling during customs clearance
• Declare exact CAS number (112-24-3) and avoid packaging that suggests retail sale to prevent Chapter 38 misclassification
