Import Tips
• Include detailed chemical analysis certificates confirming isomer structure and compliance with Chapter 29 purity requirements
• Ensure proper hazardous material declaration (UN 2387) and DOT compliance for transport
• Check for REACH-like restrictions if transshipping from EU; distinguish from CFCs which have separate quotas
