HFC-134a Refrigerant Blend R-134a/R-1234yf 70/30
A refrigerant mixture containing 70% HFC-134a (1,1,1,2-tetrafluoroethane) and 30% HFO-1234yf by mass, used in automotive air conditioning systems. It falls under HTS 3827.64.00.00 because it contains 30% or more HFC-134a without unsaturated HFOs as the primary component, though minor HFO presence is allowed if HFC-134a dominates. This blend serves as a transitional low-GWP refrigerant.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing ≥30% difluoroethane (HFC-152a) instead
Mixtures dominated by HFC-152a fall under separate simple HFC subheading, shifting from HFC-134a-specific classification.
If for industrial solvent use, not refrigerant
End-use as prepared binder or chemical mixture outside refrigerant headings moves to residual chemical preparations.
If imported as pure HFC-134a, not mixture
Pure fluorinated hydrocarbons are classified as single chemicals in Chapter 29, not mixtures in Chapter 38.

Import Tips & Compliance
• Obtain EPA Significant New Alternatives Policy (SNAP) approval and ensure mixture composition certification to verify ≥30% HFC-134a content
• Comply with AIM Act HFC import quotas; provide K-139 certificate from supplier confirming no CFCs/HCFCs and HFO content below threshold
• Label cylinders with exact mass percentages and GWP; avoid misclassification by confirming no dominant unsaturated HFOs
