9001.40.00.00 - Spectacle lenses of glass

This HTS category encompasses spectacle lenses specifically manufactured from glass. These are the primary optical components of eyeglasses or corrective eyewear. Crucially, these lenses are not mounted in frames and are intended for incorporation into finished spectacle frames. The classification hinges on both the material (glass) and the intended use as a spectacle lens.

It is important to distinguish this category from its siblings. HTS code 9001.10.00 covers optical fibers, bundles, and cables. 9001.20.00.00 pertains to polarizing material in sheets and plates. Contact lenses fall under 9001.30.00.00, differing by their application and direct wear. Spectacle lenses made from materials other than glass, such as plastic or polycarbonate, are classified under 9001.50.00.00. The "Other" category, 9001.90, is reserved for optical elements not otherwise specified.

As a leaf node, HTS code 9001.40.00.00 does not have further subdivisions. Classification within this code relies on the clear identification of the product as a glass spectacle lens, unmounted. This includes lenses that may have undergone basic optical working to achieve their refractive properties but have not yet been integrated into eyeglass frames.
