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.
