9001.20.00.00 - Sheets and plates of polarizing material

HTS Code 9001.20.00.00 specifically encompasses sheets and plates manufactured from polarizing material. These are distinct from other optical elements described in heading 9001 by their flat, planar form and their inherent property of polarizing light, meaning they selectively transmit light waves vibrating in a particular plane.

This category is differentiated from its siblings by its focus on polarizing sheets and plates, excluding items like optical fibers and bundles (9001.10.00), contact lenses (9001.30.00.00), and spectacle lenses whether of glass (9001.40.00.00) or other materials (9001.50.00.00). While all these items fall under the broader scope of optical elements, 9001.20.00.00 is exclusively for materials designed to alter the polarization state of light.

As a leaf node, HTS 9001.20.00.00 does not have further subdivisions. Classification within this code relies on confirming the material's polarizing properties and its presentation as a sheet or plate. Examples of goods that would fall here include polarizers used in LCD screens, photographic filters, and scientific equipment requiring light polarization control.
