Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains saturated HFOs like HFO-1234ze(E) ≥30%
Presence of specified saturated HFOs shifts classification to dedicated hydrofluoroolefin subheading.
If sold pre-charged in complete AC systems
Refrigerant mixtures integral to finished refrigerators/AC units classified with the machinery, not separately.
If higher lubricant content for industrial use
Organic composite solvents with significant oil content move to heading 3814.

Import Tips & Compliance
• Include Safety Data Sheet (SDS) specifying HFC-134a percentage and PAG/POE oil content; DOT approval required for pressurized cans
• Verify no HCFC contaminants via lab analysis; common pitfall is improper venting during customs inspection
• Register with EPA for HFC imports and track allocations under phasedown schedules
