Pentafluoroethane (HFC-125) Refrigerant Gas
Pentafluoroethane, known as HFC-125, is a hydrofluorocarbon used primarily as a component in refrigerant blends like R-404A and R-507 for commercial refrigeration systems. This pure, chemically defined saturated fluorinated derivative of acyclic hydrocarbons falls under HTS 2903.44.10 due to its specific chemical structure and chapter 29 applicability to separate halogenated organic compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other HFCs like R-404A
Refrigerant mixtures containing HFC-125 are classified as chemical preparations in heading 3824 rather than pure compounds.
If for industrial fire suppression use
If formulated specifically for fire extinguishers, it may fall under other fluorinated hydrocarbons; pure HFC-125 remains in 2903.44.

Import Tips & Compliance
• Obtain EPA SNAP approval and ensure compliance with the AIM Act quotas for HFC imports; provide allocation certificates
• Include Safety Data Sheets (SDS) and purity certificates (>99.9%) in documentation to verify chemical identity
• Avoid misclassification as mixtures; pure HFC-125 must be shipped in DOT-approved high-pressure cylinders
