Products classified under HTS 3827.69.00.00
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.
R-410A Air Conditioning Refrigerant
R-410A is an azeotropic HFC blend of difluoromethane (R-32) and pentafluoroethane (R-125) for high-pressure AC units. It qualifies for HTS 3827.69.00.00 as an HFC-only mixture without CFCs or HCFCs. Commonly used in new split-system air conditioners.
R-134a Replacement Blend ISCEON MO99
ISCEON MO99 is an HFC/HFO blend (R-448A variant) replacing R-134a in chillers and automotive AC, containing HFCs without CFCs/HCFCs. Classified under HTS 3827.69.00.00 for such mixtures. Offers lower GWP for retrofits.
R-449A Low-GWP Refrigerant
R-449A (HFC/HFO mix of R-32, R-125, R-134a, HFO-1234yf) replaces R-404A in transport refrigeration. HTS 3827.69.00.00 for HFC-dominant blends without CFCs/HCFCs. Reduces carbon footprint in cold chain logistics.
Solstice N40X HFC Refrigerant
Solstice N40X (R-454A: HFC-32/HFO-1234yf 72/28%) for new AC systems, very low GWP. HTS 3827.69.00.00 applies to its HFC content without CFCs/HCFCs. A2L mildly flammable classification.
HFC-152a Aerosol Propellant
HFC-152a (1,1-difluoroethane) blend for water-based aerosol adhesives and cleaners. HTS 3827.69.00.00 for halogenated mixtures with HFCs, no CFCs/HCFCs. Eco-friendly alternative to hydrocarbons.
Nu-Calgon RX11 Flush Liquid
