Fluoropolymer PTFE Tubing
High-purity tubing made from polytetrafluoroethylene (PTFE), a polymer of heading 39.04. It is unreinforced, without fittings, and used in chemical processing and high-temperature applications. PTFE is classified as a polymer of tetrafluoroethylene, but this tariff item excludes polymers of tetrafluoroethylene, so it falls under the 'Other' item.
