Products classified under HTS 3827.32.00.00
R-123 HCFC Refrigerant Blend
A hydrochlorofluorocarbon (HCFC) mixture based on HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane, subheading 2903.72) used in low-pressure centrifugal chillers for commercial refrigeration. This blend falls under HTS 3827.32.00.00 because it contains HCFCs from 2903.71-2903.75 without CFCs, designed for phase-out under Montreal Protocol. Primarily employed in air conditioning systems requiring stable, non-flammable refrigerants.
HCFC-22/R-22 Chiller Fluid Mixture
Mixture containing HCFC-22 (chlorodifluoromethane, 2903.71) with minor HFC stabilizers for use in commercial chillers and air conditioning units. Classified under 3827.32.00.00 as an HCFC-based mixture lacking CFCs, critical for legacy HVAC systems during transition period. Provides efficient heat transfer properties in large-scale cooling applications.
HCFC-123 Foam Blowing Agent Blend
Specialty mixture of HCFC-123 (2903.72) with hydrocarbon co-blowing agents for rigid polyurethane foam insulation in appliances and buildings. Meets HTS 3827.32.00.00 criteria as HCFC-containing without CFCs, used where low thermal conductivity is essential. Essential for manufacturing energy-efficient panels during HCFC transition.
R-401A HCFC Refrigerant Mix
Pre-mixed refrigerant R-401A containing HCFC-22 (2903.71), HCFC-142b (2903.74), and HFC-152a for retrofitting commercial refrigeration equipment. Falls under 3827.32.00.00 as it contains HCFCs from specified subheadings without CFCs. Zeotropic blend maintains pressure compatibility with R-12 systems.
HCFC-141b Solvent Cleaning Blend
Industrial precision cleaning mixture featuring HCFC-141b (1,1-dichloro-1-fluoroethane, 2903.75) with alcohol co-solvents for electronics manufacturing. HTS 3827.32.00.00 applies due to HCFC content from 2903.71-2903.75 absent CFCs. Non-flammable formula safe for vapor degreasing applications.
HCFC-124 Chiller Refrigerant Blend
High-capacity refrigerant mixture based on HCFC-124 (2-chloro-1,1,1,2-tetrafluoroethane, 2903.73) for centrifugal chillers in data centers. Meets 3827.32.00.00 as HCFC mixture from specified subheadings, CFC-free. Optimized for low global warming potential during phase-out.
R-409A HCFC Retrofit Blend
Drop-in replacement refrigerant R-409A containing HCFC-22 (2903.71) and HCFC-142b (2903.74) for R-12 systems in transport refrigeration. 3827.32.00.00 classification due to specified HCFCs without CFCs. Near-azeotropic blend minimizes fractionation issues.
HCFC-225ca/225cb Solvent Mixture
Azeotropic solvent blend of HCFC-225ca and HCFC-225cb (both 2903.75) for cleaning precision metal parts in aerospace manufacturing. Fits 3827.32.00.00 as HCFC mixture from 2903.71-2903.75, no CFCs. High solvency with zero ozone depletion potential relative to CFCs.
