About HS Code 900140
This category covers unmounted spectacle lenses made of glass, which have undergone optical working to correct vision. While plastic lenses have captured a larger market share, glass lenses remain valued for their superior scratch resistance, exceptional optical clarity, and stability, particularly for specific prescriptions or specialized applications. International trade involves manufacturers of ophthalmic blanks, precision lens grinders, and optical laboratories. These lenses are exported globally to optical retailers and optometrists who then custom-fit them into spectacle frames for end-users. The trade is influenced by technological advancements in lens coatings, thinning processes for high prescriptions, and the increasing global demand for high-quality vision correction. Glass lenses cater to a segment of the market that prioritizes durability and optical purity.
Products Under This Code
Single vision glass lenses, Bifocal glass lenses, Progressive glass lenses, High-index glass lenses, Photochromic glass lenses, Polarized glass lenses, Mineral glass lenses
Real World Examples
Zeiss glass lenses, Essilor glass lenses, Hoya glass lenses, Rodenstock glass lenses, Corning glass blanks
Common Misclassification
The primary confusion is with 900150 (spectacle lenses of other materials, i.e., plastic) due to the material difference. It's also distinct from 900130 (contact lenses) and 9004 (finished spectacles). The 'unmounted' and 'glass' aspects are key for correct classification.
