H295584: Application for Further Review Protest No. 5201-18-100012; Tariff classification of Specialized Turbine Insulation System
| HTS: 7019.39.10, 4.9%, Glass fibers (including glass wool) and articles thereof (for example, yarn, woven fabrics): Other: Insulation products … ." |
| Item: The specialized turbine insulation system (also referred to herein as “STIS”) is comprised of interlocking three-dimensional segments that conform to the contours of a gas turbine engine. The insulation segments consists of an outer surface of glass fiber fabric coated with silicon, an inner glass fiber fabric, and inner layering of glass fiber mats and calcium-silica fiber mats. The segments are designed to be stud-welded to the turbine engine after importation by means of stainless steel nuts and bolts. |
| Reason: The use of the STIS as thermal insulation for a gas turbine engine is technical by nature, as supported by the fact that the subject segments are involved in the operation of turbine engines. The STIS is an article of glass fiber covered under heading 7019 and excluded from being classified under Chapter 84 by virtue of Note 1(c) to chapter 84. |
