AK-225 Cleaning Solvent (HCFC-225 based)
AK-225 is a commercial-grade azeotrope containing HCFC-225ca/cb for vapor degreasing in aerospace parts cleaning. It qualifies for HTS 2903.75.01.00 when imported as the pure dichloropentafluoropropane isomer, per Chapter 29 notes on chemically defined compounds. Primarily used where non-flammable solvents are required.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as finished non-retail solvent formulation
Organic solvent preparations for industrial use are in 3814, distinct from pure HCFC compounds of 2903.
If other polyfluorinated chloroalkanes not specifically dichloropentafluoropropanes
HTS 2903.75 is exclusive to HCFC-225 isomers; similar but non-matching structures go to 2903.79 basket.
If put up in retail aerosol containers
Retail-sale chemical mixtures containing HCFCs shift to 3824 per Chapter 29 exclusion note (k).

Import Tips & Compliance
• Include Montreal Protocol exemption documentation if importing for essential uses like aviation maintenance
• Label containers with UN number 3337 and hazard class for DOT transport compliance alongside CBP requirements
• Test for purity >99% to avoid reclassification as a mixture under 3824; common pitfall in solvent imports

HCFC-225ca (1,1-Dichloro-2,2,3,3,3-pentafluoropropane)
Pure HCFC-225ca is a chlorofluorocarbon used primarily as a refrigerant gas and cleaning solvent in industrial applications. It falls under HTS 2903.75.01.00 as a halogenated derivative of acyclic hydrocarbons containing two or more different halogens, specifically dichloropentafluoropropanes. This chemical is chemically defined and separate as per Chapter 29 note (a).
HCFC-225cb (1,3-Dichloro-1,1,2,2,3-pentafluoropropane)
HCFC-225cb serves as a specialty solvent for precision cleaning in electronics manufacturing. Classified under HTS 2903.75.01.00 due to its structure as a dichloropentafluoropropane, an acyclic hydrocarbon with chlorine and fluorine halogens. Meets Chapter 29 criteria for separate chemically defined organic compounds.
HCFC-225ca Refrigerant Blend Component
Bulk HCFC-225ca imported as a pure component for blending into low-temperature refrigerants in commercial refrigeration systems. Falls under HTS 2903.75.01.00 as a dichloropentafluoropropane, halogenated acyclic hydrocarbon with Cl and F. Excluded from Chapter 27 as it's not a simple hydrocarbon isomer mixture.
Vertrel XF HCFC-225 Specialty Fluid
Vertrel XF is a high-purity HCFC-225cb-based fluid for flushing oxygen systems in medical and aerospace equipment. Classified in HTS 2903.75.01.00 as the pure dichloropentafluoropropane isomer meeting Chapter 29's separate compound definition. Used where residue-free drying is critical.
