Import Tips
• Obtain EPA Significant New Alternatives Policy (SNAP) approval and verify HFC-143a percentage via lab analysis before import
• Include Safety Data Sheets (SDS) and refrigerant purity certificates; common pitfall is mislabeling blends leading to reclassification
• Comply with AIM Act allocations for HFC production/import quotas; ensure proper venting prohibition documentation
