Import Tips
• Obtain EPA Significant New Alternatives Policy (SNAP) approval documentation if intended for refrigerant use
• Declare exact purity levels (>99%) to distinguish from formulated mixtures that might classify elsewhere
• Ensure proper UN hazardous materials classification for fluorinated gases during import clearance
