Glasses for corrective spectacles; curved, bent, hollowed or the like, not optically worked

HS code 701510 covers the production of glasses for corrective spectacles that are curved, bent, hollowed, or otherwise shaped, but not optically worked. This industry plays a crucial role in the broader optical and eyewear sector, providing essential components for the manufacture of prescription eyeglasses and other vision-correcting products. The demand for these specialized glasses is driven by the global need for vision correction, making this industry an integral part of the healthcare and consumer goods supply chains.

The production of glasses covered under HS code 701510 typically involves a multi-step process. First, raw glass materials are melted and formed into the desired curved, bent, or hollowed shapes using specialized molds and shaping techniques. The shaped glass is then carefully annealed to relieve internal stresses and ensure stability. Finally, the glasses may undergo additional finishing processes, such as polishing or edge treatment, to prepare them for integration into the final eyewear products.

The main inputs required for the production of HS code 701510 glasses include high-quality glass raw materials, such as silica, soda ash, and various mineral additives. Specialized machinery, such as glass-forming equipment, annealing ovens, and polishing tools, are also essential for the manufacturing process. Additionally, skilled labor with expertise in glass shaping and finishing techniques is necessary to ensure the production of consistent, high-quality glasses.

The primary output of the HS code 701510 industry is the production of curved, bent, or hollowed glasses that are used in the manufacture of corrective spectacles and other vision-enhancing products. These glasses are typically consumed by 900311 Spectacle frames and mountings and 900319 Parts of spectacle frames and mountings industries, which assemble the final eyewear products.
