HS Code for Polarizing sheet

Polarizing sheets are classified under HS code 9001.20, which is part of the chapter dedicated to optical, photographic, and cinematographic instruments. Heading 9001 covers optical fibers, bundles, cables, and other optical elements. Subheading 9001.20 specifically identifies "sheets and plates of polarising material." These materials are classified here because they are considered unmounted optical elements. The classification is driven by the material's optical properties—specifically its ability to polarize light—rather than its base material, which is often a polymer or plastic. According to the General Rules of Interpretation, products that are specifically named in a subheading, like polarizing sheets, must be classified there even if they could potentially fall under a more general material-based heading like Chapter 39 for plastics. This code covers the raw sheets or plates used in the manufacture of sunglasses, LCD screens, and scientific instruments, provided they have not yet been mounted into a frame or housing. The technical functionality of light filtration places it firmly within Chapter 90, which deals with high-precision optical goods.

Products Included

• Linear polarizing film sheets
• Circular polarizing plates
• Unmounted polarizing filters for displays
• Polarizing material in rolls for industrial use
• Optical grade polarizing sheets for laboratory experiments

Common Misclassification

Polarizing sheets are often misclassified under 3920.99, which covers other plates and sheets of plastics. While the substrate is often plastic, the optical function of polarization requires classification in Chapter 90. Another common error is using 9001.90, the residual category for other optical elements. Since 9001.20 specifically names polarizing material, it must be used instead of the general 9001.90 code. Additionally, finished polarizing filters for cameras are classified under 9002.20 as mounted optical elements.

FAQ

What is the HS code for polarizing sheets?

The specific HS code for unmounted sheets and plates of polarizing material is 9001.20.

Are polarized sunglasses classified under this code?

No, finished sunglasses are classified under HS code 9004.10. Code 9001.20 only applies to the raw polarizing material in sheet or plate form.
