Import Tips
• Provide salt formation assay (Cl- content verification) to distinguish from free base under amine-function classification rules
• Label as UN 2683 (corrosive solid) with proper PG II packaging to meet IMDG/49CFR hazardous materials regulations
• Confirm no anti-caking agents exceed Chapter 29 note (f) stabilizer thresholds to maintain pure salt status
