Products classified under HTS 2903.71.01.00
Chlorodifluoromethane (HCFC-22) Refrigerant Gas
Pure chlorodifluoromethane (HCFC-22) is a hydrochlorofluorocarbon used primarily as a refrigerant in air conditioning and refrigeration systems. It falls under HTS 2903.71.01.00 as a halogenated derivative of acyclic hydrocarbons containing two or more different halogens (chlorine and fluorine). This chemically defined compound is supplied in pressurized cylinders for industrial and commercial applications.
HCFC-22 (R-22) Air Conditioner Refrigerant Cylinder
A 30 lb cylinder of chlorodifluoromethane (HCFC-22), designated R-22, used to recharge residential and commercial air conditioning units. Classified under HTS 2903.71.01.00 due to its chemical structure as a chlorinated and fluorinated acyclic hydrocarbon. It meets chapter requirements for separate chemically defined organic compounds.
Medical Refrigerator HCFC-22 Coolant
Chlorodifluoromethane (HCFC-22) formulated for use in vaccine storage refrigerators, provided as a pure compound. It is a halogenated acyclic hydrocarbon with chlorine and fluorine, directly classifiable under HTS 2903.71.01.00 per chapter notes for chemically defined compounds.
Industrial Chiller HCFC-22 Refrigerant
High-purity chlorodifluoromethane (HCFC-22) in 100 lb returnable cylinders for large-scale industrial chillers. As a separate chemically defined compound with multiple halogens on an acyclic hydrocarbon, it precisely matches HTS 2903.71.01.00.
HCFC-22 Recovery Cylinder for Recycling
Reclaimed chlorodifluoromethane (HCFC-22) in dedicated recovery cylinders for recycling in HVAC servicing. Still classified as the pure compound under HTS 2903.71.01.00 if meeting ARI-700 purity standards without disqualifying additives.
R-22 Compatible Retrofit Refrigerant Base
Pure HCFC-22 serving as base stock for authorized retrofit blends in older systems. Its chemical identity as chlorodifluoromethane places it squarely in HTS 2903.71.01.00 for halogenated acyclic hydrocarbons.
