3827.65.00.00/R-410A Refrigerant Blend/China

R-410A Refrigerant Blend from China

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.

Import Tips

• Verify exact composition via supplier certificate of analysis to confirm ≥20% HFC-32 and ≥20% HFC-125 for proper HTS classification

• Obtain EPA SNAP approval documentation and ensure compliance with HFC import quotas under the AIM Act

• Label cylinders clearly with UN number 3337 and avoid shipping with CFCs/HCFCs to prevent reclassification
