Dichlorotetrafluoroethane (CFC-114) Refrigerant Gas
Dichlorotetrafluoroethane (CFC-114), a perhalogenated acyclic hydrocarbon with only fluorine and chlorine, is classified under HTS 2903.77.00.30 as a halogenated derivative containing two different halogens. This chemical compound was historically used as a refrigerant in industrial cooling systems and as a blowing agent in foam production. Its classification is based on chapter 29 notes for separate chemically defined organic compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other refrigerants or additives for commercial use
Blends or mixtures of halogenated hydrocarbons are classified in heading 3824 as prepared chemical preparations, which occurs later in numerical order per Chapter 29 note.
If only chlorinated without fluorine (e.g., similar acyclic chlorofluorocarbons misidentified)
Heading 2903.71 covers chlorodifluoromethane and similar with only chlorine and fluorine but different specific compound; exact chemical definition determines subheading.
If imported in petroleum-derived mixtures or as a crude distillate
Petroleum gases or hydrocarbons fall under Chapter 27; Chapter 29 excludes mixtures classifiable there per exclusion note (b).

Import Tips & Compliance
• Verify compliance with Montreal Protocol and EPA regulations on CFC imports, as production is globally phased out; obtain necessary exemptions or recycling certifications
• Provide detailed chemical purity analysis and SDS documentation to confirm it matches the exact subheading for dichlorotetrafluoroethane
• Avoid misclassification as mixtures; ensure product is chemically defined per Chapter 29 note (a) to prevent customs reclassification
