Products classified under Tariff item 2903.48.00.00
HFC-365mfc (1,1,1,3,3-Pentafluorobutane) Technical Grade
This is the pure, chemically defined compound 1,1,1,3,3-pentafluorobutane (HFC-365mfc), a saturated fluorinated acyclic hydrocarbon. It is used as a blowing agent and specialty solvent, and its technical grade purity does not affect classification under the named tariff item.
2903.48.00HFC-365mfc Blowing Agent Cylinder
HFC-365mfc (1,1,1,3,3-pentafluorobutane) is a saturated fluorinated acyclic hydrocarbon, a separate chemically defined organic compound. It is packaged in steel cylinders for use as a physical blowing agent in rigid foam production, which does not alter its classification under this tariff item.
2903.48.00HFC-365mfc with Transport Stabilizer
HFC-365mfc with a minimal nitrile stabilizer (<0.1%) added solely for transport stability is still classified under this tariff item. Chapter 29 Note 1(f) permits added stabilizers necessary for preservation or transport, provided they do not make the product suitable for a specific use.
2903.48.00HFC-43-10mee (1,1,1,2,2,3,4,5,5,5-Decafluoropentane) Electronic Grade
HFC-43-10mee (1,1,1,2,2,3,4,5,5,5-decafluoropentane) is a saturated fluorinated acyclic hydrocarbon, a separate chemically defined compound. Its electronic grade purity for precision cleaning does not change its classification under this named tariff item.
2903.48.00HFC-43-10mee Heat Transfer Fluid Grade
HFC-43-10mee purified for use as a dielectric heat transfer fluid is the named compound 1,1,1,2,2,3,4,5,5,5-decafluoropentane. End use as a heat transfer fluid does not affect classification, as the product is the chemically defined compound listed in this tariff item.
