Import Tips
• Small quantity research imports (<25kg/year) may qualify for EPA de minimis exemption from HFC quotas
• Include institutional end-user statement and SDS with GC-MS purity analysis for customs clearance
• Avoid declaring as 'commercial refrigerant' which triggers stricter industrial quotas and documentation
