The applicable subheading for the polybutadiene rubber will be 4002.20.0000, Harmonized Tariff Schedule of the United States (HTS), which provides for butadiene rubber. The rate of duty will be free. 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 Frank Cantone at 212-637-7018. Sincerely, Robert B. Swierupski Director, National Commodity Specialist Division
