NY C80233 October 21, 1997 CLA-2-90:RR:NC:1:105 C80233 CATEGORY: Classification TARIFF NO.: 9025.90.0000 Mr. Raj Madhavan International Metal Products 2002 Jimmy Durante Blvd., Suite 326 Del Mar, CA 92014 RE: The tariff classification of Thermowells from Singapore and India Dear Mr. Madhavan: In your letter dated September 26, 1997, you requested a tariff classification ruling. Thermowells are designed to shield and protect temperature sensors (temperature probe, RTD-resistance temperature detector, thermocouple and bi-metal thermometer) against corrosion, mechanical damage and other variables while permitting easy installation of sensor replacements. They will be used in machines which measure temperature (e.g., boilers, heat exchangers, heaters, and condensers). The applicable subheading for the thermowells will be 9025.90.0000, Harmonized Tariff Schedule of the United States (HTS), which provides for thermometers, parts and accessories. The duty rate will be 3.1 percent ad valorem. Articles which are classifiable under subheading 9025.90.0000, HTS, which are products of India are entitled to duty free treatment under the Generalized System of Preferences (GSP) upon compliance with all applicable regulations. We can not determine the country of origin of your goods with the information you furnished. For us to do so, you will need to furnish detailed information describing what manufacturing processes are done in each country including the costs of materials and labor added in each country. This ruling is being issued under the provisions of Part 177 of the Customs Regulations (19 C.F.R. 177). A copy of this 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 this ruling, contact National Import Specialist Eric Francke at (212) 466-5669. Sincerely, Robert B. Swierupski Director, National Commodity Specialist Division
