Import Tips
• Provide detailed blend composition certificate showing ≥15% HFC-143a; customs often requires GC-MS analysis verification
• Register with EPA's HFC phasedown program and maintain chain-of-custody records from manufacturer to importer
• Avoid classifying as 'used refrigerant' which requires different waste handling under 3825; ensure virgin product status
