AK-225 Cleaning Solvent (HCFC-225 based)
AK-225 is a commercial-grade azeotrope of HCFC-225ca and HCFC-225cb, used as a cleaning solvent for vapor degreasing in aerospace parts. It falls under this tariff item because it is a dichloropentafluoropropane mixture, a halogenated derivative of acyclic hydrocarbons containing two different halogens, and is not excluded by Chapter 29 notes.
2903.75.00HCFC-225ca (1,1-Dichloro-2,2,3,3,3-pentafluoropropane)
HCFC-225ca is a pure dichloropentafluoropropane isomer used as a refrigerant and industrial cleaning solvent. It is classified here as a halogenated derivative of an acyclic hydrocarbon containing chlorine and fluorine, meeting Chapter 29's definition of a separate chemically defined organic compound.
2903.75.00HCFC-225ca Refrigerant Blend Component
Bulk HCFC-225ca imported as a pure component for blending into low-temperature refrigerants is classified under this tariff item. It is a dichloropentafluoropropane, a halogenated acyclic hydrocarbon, and qualifies as a separate chemically defined compound under Chapter 29.
2903.75.00HCFC-225cb (1,3-Dichloro-1,1,2,2,3-pentafluoropropane)
HCFC-225cb is a specialty solvent for precision cleaning in electronics manufacturing, classified as a dichloropentafluoropropane. It is a halogenated derivative of an acyclic hydrocarbon with chlorine and fluorine, meeting Chapter 29's requirements for separate chemically defined compounds.
2903.75.00Vertrel XF HCFC-225 Specialty Fluid
Vertrel XF is a high-purity HCFC-225cb-based fluid used for flushing oxygen systems in medical and aerospace equipment. It falls under this tariff item as a dichloropentafluoropropane, provided it is not formulated with additives that make it suitable for a specific use beyond general cleaning.
