Classification focused on whether optical sheet components are optical elements and whether they are 'mounted' or merely embedded, determining tariff placement. Prisms are optical elements that refract/reflect light but do not polarise; the DBEF layer is a polarising sheet. The Optical Sheet Complex and Optical Sheet High Color are designed solely for use in LED televisions and cannot be used independently; accordingly, under the principal use rule for parts they are classifiable with the television set (heading 8529). Quantum dots embedded in polymer are not 'mounted' and therefore not classifiable as mounted optical elements.
