Import Tips

• Provide retrofit compatibility certificates; common issue is oil miscibility testing not documented

• Label with exact HFO/HFC ratios as HFOs may trigger separate regulations under 2903 if predominant

• Use temperature-compensated filling scales for accurate charge weights during customs weigh-in
