Unmounted Aspheric Polymer Lens
An aspheric lens molded from optical-grade polymer (acrylic), used to minimize spherical aberration in cameras and projectors. Classified under HTS 9001.90.40.00 as an unmounted lens of plastic material, excluding unworked glass. Its non-spherical surface requires precise molding for optical performance.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not optically functional
Plastic plates/sheets/films not qualifying as optical elements classify under Chapter 39 as other plastics.
If for contact lens use and mounted
Contact lenses, even polymer, when mounted or assembled go to 9002.90.
If designed as optical fiber components
Chapter exclusions send optical fiber cables/elements to 8544.

Import Tips & Compliance
• Include refractive index and Abbe number data in documentation to prove optical function
• Declare exact polymer composition; generic plastics may fall under Chapter 39
• Test for contamination-free packaging to prevent surface defects during import
