Import Tips

• Obtain EPA Significant New Alternatives Policy (SNAP) approval and verify compliance with HFC phase-down schedules under the AIM Act before importing

• Ensure cylinders meet DOT 49 CFR pressure vessel specifications with proper DOT/UN markings; include Safety Data Sheets (SDS) in English

• Declare exact purity levels (>99%) to avoid reclassification; common pitfall is insufficient documentation of non-ozone depleting status
