Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If plastic self-adhesive film without polarizing function
Plain plastic sheets go to Chapter 39; polarizing optical function moves to Chapter 90.
If mounted as optical filters
Unmounted polarizing sheets are 9001; assembled into filters classify under 9002.20.
If non-optical plastic plates
Material composition alone insufficient; optical end-use required for Chapter 90.

Import Tips & Compliance
• Measure and declare polarization efficiency (>99%) and thickness to confirm polarizing material status
• Distinguish from window film by proving optical function via transmission axis specs
• Rolls over certain lengths may require statistical breakouts; check HTS reporting instructions
