Products classified under HTS 3827.65.00.00
R-410A Refrigerant Blend
R-410A is a near-azeotropic HFC refrigerant mixture consisting of 50% difluoromethane (HFC-32) and 50% pentafluoroethane (HFC-125) by weight, used as a replacement for R-22 in air conditioning systems. It falls under HTS 3827.65.00.00 because it contains 20% or more by mass of both HFC-32 and HFC-125, without CFCs or HCFCs. This blend is widely used in residential and commercial HVAC equipment for its high efficiency and non-ozone depleting properties.
HFC-410A Air Conditioner Refrigerant Gas
HFC-410A is an azeotropic-like blend of 50% HFC-32 (difluoromethane) and 50% HFC-125 (pentafluoroethane), designed for high-pressure air conditioning and heat pump systems. Classified under HTS 3827.65.00.00 due to its balanced composition exceeding 20% of each specified HFC, excluding CFCs/HCFCs. It provides superior cooling capacity compared to older refrigerants.
Genetron AZ-20 Refrigerant Mixture
Genetron AZ-20 (R-410A equivalent) is a blend with approximately 50% difluoromethane (HFC-32) and 50% pentafluoroethane (HFC-125), used in split-system air conditioners. It qualifies for HTS 3827.65.00.00 as a halogenated hydrocarbon mixture with ≥20% of each key HFC component, free of ozone-depleting substances. Ideal for modern, energy-efficient cooling applications.
Puron R-410A HVAC Refrigerant Cylinder
Puron (branded R-410A) is a 50/50 weight percent mixture of HFC-32 and HFC-125, supplied in 25 lb recoverable cylinders for HVAC servicing. Under HTS 3827.65.00.00 due to exceeding 20% thresholds for both HFCs without CFCs/HCFCs. Commonly used in new installations and retrofits of central AC units.
Eco-Friendly R-410A Heat Pump Refrigerant
This R-410A variant is a precise 50% HFC-32 / 50% HFC-125 blend for heat pump systems, offering high volumetric capacity. It meets HTS 3827.65.00.00 criteria with >20% each HFC, no CFCs/HCFCs, and low global warming potential relative to predecessors. Used in residential heating/cooling reversible units.
Dupont Suva 410A Refrigerant Blend
DuPont Suva 410A is a commercial 50/50 HFC-32/HFC-125 mixture for commercial refrigeration and chillers. Classified in HTS 3827.65.00.00 for its specific ≥20% composition of both HFCs, excluding banned substances. Provides non-flammable, efficient cooling in medium-temperature applications.
50/50 HFC-32/HFC-125 Bulk Refrigerant
Bulk tanker or ISO container shipments of 50% difluoromethane (HFC-32) and 50% pentafluoroethane (HFC-125) blend for large-scale HVAC filling. Fits HTS 3827.65.00.00 precisely due to balanced mass percentages >20% each, CFC/HCFC-free. Essential for manufacturers of window and split AC units.
