Products classified under Tariff item 2903.72.00
2,2-Dichloro-1,1,1-trifluoroethane Lab Grade
2,2-Dichloro-1,1,1-trifluoroethane lab grade is a high-purity, chemically defined compound (C2HCl2F3) used as a laboratory reagent for organic synthesis and analytical standards. It is a halogenated derivative of acyclic hydrocarbons containing both chlorine and fluorine, falling under tariff item 2903.72.00 as HCFC-123. The product is not put up for retail sale or mixed with other substances, so it qualifies as a separate chemically defined organic compound under Chapter 29.
Dichlorotrifluoroethane USP Grade (HCFC-123)
Dichlorotrifluoroethane USP grade (HCFC-123) is a pharmaceutical-grade, chemically defined compound used as a propellant in metered dose inhalers. It is a halogenated acyclic hydrocarbon with chlorine and fluorine atoms, meeting the description of tariff item 2903.72.00. The product is not put up in measured doses or for retail sale, so it is not excluded by Section VI Note 2.
HCFC-123 (2,2-Dichloro-1,1,1-trifluoroethane)
Pure HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane) is a hydrochlorofluorocarbon used as a refrigerant in low-pressure centrifugal chillers for commercial air conditioning. It is a chemically defined halogenated acyclic hydrocarbon with both chlorine and fluorine, matching tariff item 2903.72.00. The product is not excluded by Chapter 29 notes as it is not a fuel, enzyme, or other excluded good.
HCFC-123 Chiller Refrigerant Cylinder
HCFC-123 chiller refrigerant cylinder contains pure dichlorotrifluoroethane in a disposable 50 lb cylinder for centrifugal chiller retrofits. The product is a separate chemically defined compound, not put up for retail sale in measured doses, and falls under tariff item 2903.72.00. The cylinder is packaging, not a factor affecting classification.
R-123 Refrigerant (HCFC-123)
R-123 refrigerant (HCFC-123) is industrial-grade dichlorotrifluoroethane supplied in 100 lb cylinders for chiller systems. It is a separate chemically defined compound, not put up for retail sale, and falls under tariff item 2903.72.00. The product is a halogenated acyclic hydrocarbon with chlorine and fluorine, consistent with the tariff description.
