Lenses, spectacle; unmounted, of glass, excluding elements of glass not optically worked

HS v2017 Code: 900140

About lenses, spectacle; unmounted, of glass, excluding elements of glass not optically worked

hs code 900140 covers the import and export of unmounted glass lenses used in spectacles and eyewear. This is a critical component of the broader optics and optical equipment industry, which plays a vital role in the manufacturing of various optical devices and instruments. The global trade in these specialized glass lenses is an important part of the international supply chain for the eyewear and vision care sectors.

Production process

The production of unmounted glass lenses for spectacles involves a multi-step process. First, high-quality raw glass materials are carefully selected and melted at high temperatures. The molten glass is then shaped and formed into the desired lens curvatures and dimensions using precision molds and grinding techniques. Finally, the lenses undergo polishing and optical coatings to enhance their visual clarity and performance.

Production inputs

The key inputs for the 900140 industry include high-purity glass materials, advanced manufacturing equipment such as precision lens grinders and polishers, as well as skilled technicians to operate the production machinery. Additionally, the industry relies on specialized optical design software and testing equipment to ensure the lenses meet stringent quality and performance standards.

Production outputs

The primary output of hs code 900140 is unmounted glass lenses that are used in the manufacture of 900311 spectacles, goggles and the like, corrective, protective or other, 900319 spectacles, goggles and the like, other than corrective, and other optical devices. These lenses may also be consumed by industries producing 900190 instruments and appliances used in medical, surgical, dental or veterinary sciences, other than those directly in heading 9018, 900290 parts and accessories for instruments and appliances used in medical, surgical, dental or veterinary sciences, and various scientific and industrial equipment.
