Products classified under HTS 2903.49.00.00
Perfluoropentane
Perfluoropentane (C5F12) is a fully fluorinated acyclic hydrocarbon where all hydrogen atoms are replaced by fluorine, making it a saturated fluorinated derivative. It falls under HTS 2903.49.00.00 as 'other' saturated fluorinated derivatives of acyclic hydrocarbons, distinct from methane, ethane, and propane derivatives specified earlier in the heading. Commonly used in electronics cleaning and as a refrigerant alternative.
Perfluorohexane
Perfluorohexane (C6F14), also known as FC-72, is a saturated perfluorinated acyclic hydrocarbon used in thermal management and precision cleaning. Classified under HTS 2903.49.00.00 as it represents 'other' saturated fluorinated derivatives beyond the shorter-chain specifics. Its high density and chemical inertness make it ideal for immersion cooling.
1H-Perfluorohexane
1H-Perfluorohexane (C6F13H) is a hydrofluoroalkane with one hydrogen atom, qualifying as a saturated fluorinated derivative of acyclic hydrocarbons. It fits HTS 2903.49.00.00 as 'other' beyond specific short-chain compounds, used in medical imaging and as a breathable liquid. The single C-H bond maintains its classification within this pure compound heading.
Perfluorobutane
Perfluorobutane (C4F10) is a fully fluorinated saturated acyclic hydrocarbon used in aerosol propellants and ultrasound contrast agents. Although longer than specified trifluoro- and pentafluoro- derivatives, it falls under HTS 2903.49.00.00 as 'other' saturated fluorinated acyclic hydrocarbons per Chapter 29 scope.
Perfluorooctane
Perfluorooctane (C8F18) serves as a reference standard for surface tension measurements and in liquid immersion cooling systems. This saturated fluorinated acyclic hydrocarbon is captured by HTS 2903.49.00.00 as 'other' derivatives, meeting Chapter 29 requirements for chemically defined organic compounds.
Heptafluoropropane
Heptafluoropropane (CF3CHFCF3, HFC-227ea) is a hydrofluorocarbon with seven fluorine atoms, used as a clean fire suppressant. As a saturated fluorinated derivative of acyclic propane, it qualifies for HTS 2903.49.00.00 'other' category, being chemically defined per Chapter notes.
Nonafluorobutane
Nonafluorobutane (C4F9H) represents hydrofluorobutanes used in precision cleaning and carrier fluids. This saturated fluorinated acyclic hydrocarbon fits HTS 2903.49.00.00 as an 'other' derivative, distinct from fully perfluorinated or short-chain specifics.
Perfluoroneopentane
Perfluoroneopentane (C(CH3)3CF3 fully fluorinated) is a branched saturated fluorinated acyclic hydrocarbon used in liquid cooling. Classified under HTS 2903.49.00.00 as 'other' despite branched structure, as acyclic per Chapter 29 definitions.
