Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dominant HFO-1234yf component
Hydrofluoroolefins like HFO-1234yf are unsaturated derivatives under 2903, shifting from HFC mixtures.
If for used/recycled blends with impurities
Contaminated refrigerants may qualify as 'other' hazardous mixtures in 3824.
If derived from petroleum and sold as light oil
Petroleum-based solvent mixtures exclude chemical preparations, per chapter notes.

Import Tips & Compliance
• 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
