Subheadings
Products classified under HTS 2903.44.10
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.
1,1,2-Trifluoroethane (HFC-143) Research Chemical
1,1,2-Trifluoroethane (HFC-143), a specific isomer listed in HTS 2903.44.10, supplied in lecture bottles for laboratory synthesis and chemical research applications. Its classification follows chapter 29 rules for chemically defined halogenated acyclic hydrocarbons.
Pentaerythritol Tetranitrate Stabilized HFC-125
No, correction: Pure HFC-125 with anti-dusting stabilizer for safe pneumatic filling systems. Permitted under chapter note 2(g) for identification/safety without changing general use, maintaining HTS 2903.44.10 classification.
HFC-125/HFC-143a Calibration Gas Mixture
No, pure: Separate HFC-125 cylinder for gas chromatography calibration standards. Chemically defined per chapter note 2(a), classified HTS 2903.44.10.
1,1,2-Trifluoroethane (HFC-143) Propellant Grade
Propellant-grade 1,1,2-trifluoroethane (HFC-143) for aerosol pharmaceutical delivery systems, maintained pure for general industrial use under HTS 2903.44.10.
HFC-143a Electronic Grade Gas
Ultra-high purity 1,1,1-trifluoroethane (HFC-143a) for semiconductor cleaning processes, classified as chemically defined compound under HTS 2903.44.10.
Pentafluoroethane (HFC-125) Medical Propellant
Pharmaceutical grade HFC-125 for metered dose inhalers, pure form qualifying under general chapter 29 provisions for HTS 2903.44.10.
1,1,1-Trifluoroethane (HFC-143a) Pure Gas Cylinder
1,1,1-Trifluoroethane (HFC-143a) is a potent hydrofluorocarbon supplied in high-pressure cylinders for use in refrigerant blends and foam blowing applications. As a separate chemically defined saturated fluorinated acyclic hydrocarbon, it is precisely classified under HTS 2903.44.10 per chapter 29 notes.
HFC-125 Pentafluoroethane Technical Grade
Technical grade pentafluoroethane (HFC-125) with >99% purity, stabilized for transport in ton cylinders, used in air conditioning refrigerant manufacturing. This halogenated derivative qualifies under HTS 2903.44.10 as it meets chapter notes for separate organic compounds with permitted stabilizers.
HFC-143a 1,1,1-Trifluoroethane Bulk Industrial
Bulk industrial 1,1,1-trifluoroethane (HFC-143a) for integration into R-404A refrigerant production and polyurethane foam blowing agents. Classified under HTS 2903.44.10 as a pure saturated fluorinated derivative per the full HTS hierarchy.
