Import Tips
• Provide third-party assay confirming HFC-134a ≥30% and absence of unsaturated HFOs; customs often requires gas chromatography reports
• Ensure UN pressure vessel certification (e.g
• DOT 39 cylinders); avoid delays from missing reclaim documentation
• Monitor CARB and state-level HFC bans that may restrict certain blends post-import
