Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing longer chain alkyl groups like hexyl
Longer chain monoamines fall under the 'other' acyclic monoamines category outside the specific propyl/butyl listing.
If imported as a formulated mixture with solvents
Mixtures of amines with other substances are classified in Chapter 38 as chemical preparations, not pure compounds.

Import Tips & Compliance
• Provide detailed chemical purity certificates and SDS to verify it meets Chapter 29 criteria for chemically defined compounds
• Ensure proper UN packaging for flammable liquids (Class 3) and include safety data for transport
• Avoid misclassification as mixtures; confirm single isomer content to prevent reclassification to Chapter 38
