Import Tips & Compliance
• Obtain Safety Data Sheets (SDS) and purity certificates to confirm chemical definition per Chapter 28 Note 1; impurities may shift classification
• Comply with DOT/UN 1080 hazardous material regulations for transport; ensure cylinders meet 49 CFR specifications
• Verify EPA reporting requirements under SF6 emission rules; improper documentation can lead to penalties
