Import Tips
• Submit NMR/GC assay confirming >95% purity and ethyl substitution pattern to validate polyamine heading
• Classify as UN 2922 (corrosive liquid, flammable) requiring steel drums with UN certification for ocean transport
• Watch for reclassification if ethyl content >50% shifts material to monoamine-dominant structures
