Import Tips

• Verify compliance with EPA regulations under the AIM Act for HFC imports, including mandatory reporting of production and consumption allowances

• Ensure cylinders meet DOT pressure vessel standards (49 CFR) and include Safety Data Sheets (SDS) detailing GWP of 14,700

• Avoid misclassification as a CFC by confirming zero chlorine/ bromine content; common pitfall is confusing with Chapter 27 hydrocarbons
