HS v2022 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 spectacle lenses made of glass, excluding elements of glass that have not been optically worked. This industry plays a crucial role in the global eyewear and optical products market, providing essential components for the manufacturing of prescription glasses, sunglasses, and other vision-correcting devices. As a key input for the broader optical industry, the trade of these lenses is an important economic activity with significant implications for healthcare, fashion, and technology sectors worldwide.

Production process

The production of unmounted spectacle lenses under HS code 900140 typically involves a multi-step process. First, high-quality glass is carefully selected and cut into the desired lens shapes. The lenses then undergo a series of grinding, polishing, and edging operations to achieve the precise optical properties and dimensions required. Advanced computer-controlled machinery is often used to ensure consistency and accuracy throughout the manufacturing process. Finally, the lenses are inspected, packaged, and prepared for distribution to eyewear manufacturers and optical retailers.

Production inputs

The main inputs required for the production of HS code 900140 lenses include high-purity glass, specialized grinding and polishing equipment, and skilled labor. Glass suppliers provide the raw material, which must meet stringent optical and dimensional specifications. Manufacturers also rely on advanced computer-controlled machinery, as well as a workforce trained in lens fabrication techniques, to ensure the quality and consistency of the final product.

Production outputs

The primary output of HS code 900140 is unmounted spectacle lenses made of glass, which are then incorporated into a wide range of eyewear products. These lenses are consumed by 900410 Spectacles, sunglasses and corrective lenses manufacturers, who assemble them into complete eyeglasses and sunglasses. Additionally, the lenses may be used in the production of 900190 Lenses, optical, n.e.s. in heading no. 9001, which includes other types of optical lenses not classified elsewhere.
