Import Tips & Compliance

Obtain EPA Significant New Alternatives Policy (SNAP) approval and ensure proper labeling as required under 40 CFR Part 82

Provide Safety Data Sheets (SDS) and verify HFC content to avoid reclassification; common pitfall is missing Phaseout Management Plan documentation

Declare exact composition percentages as blends vary; use DOT-approved cylinders for transport to comply with hazardous materials regulations
