The expansion joints are used to join rigid pipes where flexibility is necessary. They provide for axial travel, misalignment and angular deflection. The applicable subheading for the PTFE expansion joints will be 3917.40.0090, Harmonized Tariff Schedule of the United States (HTS), which provides for tubes, pipes and hoses and fittings therefor (for example, joints, elbows, flanges) of plastics...fittings, other. The rate of duty will be 5.3 percent ad valorem. This ruling is being issued under the provisions of Part 177 of the Customs Regulations (19 C.F.R. 177). A copy of the ruling or the control number indicated above should be provided with the entry documents filed at the time this merchandise is imported. If you have any questions regarding the ruling, contact National Import Specialist Joan Mazzola at 646-733-3023. Sincerely, Robert B. Swierupski Director, National Commodity Specialist Division
