N250341 March 14, 2014 CLA-2-39:OT:RR:NC:N2:237 CATEGORY: Classification TARIFF NO.: 3910.00.0000 Cindy Johnson Global trade Compliance Specialist FMC Technologies Incorporated 5875 N. Sam Houston Parkway Houston, Texas 77086 RE: Tariff classification of a silicon-based resin filled with glass microspheres from England. Dear Ms. Johnson: In your letter dated February 11, 2014 you requested a tariff classification ruling. Novolastic is a room-temperature vulcanizing silicone resin compounded with hollow glass microspheres designed to reduce density and lower thermal conductivity. The glass microspheres are relatively thick-walled and provide good crush strength and buoyancy. The filled resin is used in casting syntactic silicone foam block, sheet or custom shapes that provide thermal insulation of equipment, subsea christmas trees, manifolds, jumper piping, sleds and similar components. The insulation is pliable and allows for thermal or mechanical expansion or movement of piping such as flowline jumpers without cracking or breaking the insulating layer. Fluids are produced at high temperatures and equipment must be capable of handling extremely hot fluid while submersed in water close to freezing. Subsea lines are insulated to maintain produced liquid hydrocarbons at a sufficiently high temperature to prevent precipitation of wax and formation of gas hydrates, particularly during a production shutdown. The applicable subheading for the silicon-based resin filled with hollow glass microspheres will be 3910.00.0000, Harmonized Tariff Schedule of the United State, which provides for: Silicones in primary forms. The rate of duty will be 3% ad valorem. This merchandise may be subject to the requirements of the Toxic Substances Control Act (TSCA), which are administered by the U. S.
