HFC-134a Refrigerant Gas
1,1,1,2-Tetrafluoroethane (HFC-134a) is a hydrofluorocarbon refrigerant used primarily in automotive air conditioning systems and domestic refrigerators. This pure, chemically defined organic compound falls under HTS 2903.45.10.00 as a saturated fluorinated derivative of acyclic hydrocarbons.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with lubricating oils for direct system charging
Mixtures of fluorinated hydrocarbons with additives like lubricants are classified as chemical preparations rather than pure compounds.
If imported pre-charged in refrigerating equipment
Refrigerants contained within assembled refrigeration units fall under machinery headings, not separate chemicals.
