R-404A Refrigerant Blend
R-404A is a zeotropic HFC refrigerant mixture containing R-125, R-143a, and R-134a, used in commercial refrigeration systems like supermarket display cases. It falls under HTS 3827.69.00.00 as a mixture containing hydrofluorocarbons (HFCs) without CFCs or HCFCs. This classification applies to its role as a non-ozone-depleting cooling agent.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as unmixed single HFC component
Individual fluorinated hydrocarbons like pure R-134a are classified under Chapter 29 as halogenated derivatives, not mixtures.
If contaminated with listed persistent organic pollutants
Mixtures containing specific banned substances like PCBs or endosulfan fall under 3824 subheadings per legal notes.
If specifically prepared as anti-freeze or heat transfer fluid
HFC-based formulations designed for automotive or industrial cooling are classified under heading 3811 for anti-freezing preparations.

Import Tips & Compliance
• Obtain EPA Significant New Alternatives Policy (SNAP) approval and ensure proper labeling as required under 40 CFR Part 82
• Provide Safety Data Sheets (SDS) and verify HFC content to avoid reclassification; common pitfall is missing Phaseout Management Plan documentation
• Declare exact composition percentages as blends vary; use DOT-approved cylinders for transport to comply with hazardous materials regulations
