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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chlorodifluoromethane or similar but not pentafluorinated
Other specific HCFCs with different fluorine counts fall under 2903.71; only dichloropentafluoropropanes are in 2903.75.
If sold as stabilized mixture with anti-dusting agents exceeding Chapter 29 note (g)
Additives rendering it suitable for specific retail use shift classification from pure compound to chemical preparation in 3824.
If saturated acyclic hydrocarbon without halogens
Base hydrocarbons without halogen substitution belong in Chapter 29 earlier headings like 2901, not halogenated derivatives.

Import Tips & Compliance
• Obtain TSCA pre-manufacture notice if new to US inventory; confirm existing listing for HCFC-225 isomers
• Declare exact isomer (225ca vs 225cb) on entry documents to match precise HTS subheading 2903.75.01.00
• Watch for anti-dumping duties or phase-down tariffs on ozone-depleting substances; check current Commerce Dept. orders
