Products classified under HTS 3827.64.00.00
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.
HFC-134a Auto AC Recharge Kit Mixture
Pre-mixed refrigerant for DIY automotive air conditioner recharging, consisting of 65% HFC-134a with lubricants and leak sealer additives. Classified under HTS 3827.64.00.00 due to HFC-134a comprising over 30% by mass, with no CFCs/HCFCs or dominant HFOs. Commonly sold in 12 oz cans for consumer vehicle maintenance.
Commercial Refrigerator HFC-134a Service Blend
Service blend for supermarket refrigeration systems with 80% HFC-134a, 15% HFC-125, and 5% lubricants, used for retrofitting and maintenance. Meets HTS 3827.64.00.00 criteria as HFC-134a exceeds 30% by mass without prohibited substances or dominant HFOs. Essential for food retail cold chain equipment.
HFC-134a Leak Detection Refrigerant Blend
Specialty blend with 50% HFC-134a, UV dye, and nitrogen for detecting leaks in HVAC systems. Falls under HTS 3827.64.00.00 due to dominant HFC-134a content without HFOs or banned substances. Used by HVAC technicians for non-destructive leak testing.
Industrial Chiller HFC-134a Top-Off Blend
Blend containing 75% HFC-134a with minor HFC-32 for topping off large industrial water chillers. HTS 3827.64.00.00 applies as HFC-134a exceeds 30% without unsaturated HFOs or ozone depleters. Used in manufacturing process cooling.
HFC-134a Domestic Heat Pump Refrigerant Mixture
Refrigerant blend with 55% HFC-134a and POE oil for residential heat pump systems. Classified in HTS 3827.64.00.00 for ≥30% HFC-134a content, no HFO dominance. Supports heating/cooling in homes.
HFC-134a/PAG Oil Lubricant Mixture for AC Compressors
Mixture of 60% HFC-134a and 40% polyalkylene glycol (PAG) oil for lubricating automotive AC compressors during manufacturing. Qualifies for HTS 3827.64.00.00 with HFC-134a well above 30% threshold and no excluded fluorocarbons. Used in OEM assembly lines.
