Anti-Reflective Coated Glass Lenses
High-index glass spectacle lenses featuring a multi-layer anti-reflective coating to minimize glare and improve light transmission for better night vision and aesthetics. These unmounted lenses are optically worked from borosilicate glass and intended exclusively for eyeglass frames. HTS 9001.40.00.00 covers all glass spectacle lenses regardless of optical coatings, distinguishing them from unworked glass.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polycarbonate with similar AR coating
Material composition determines primary classification; plastic AR-coated lenses go to 9001.50, not glass subheading.
If designed for use in optical measuring instruments
Chapter 90 note 1(a) excludes lenses for technical instrument use; those for microscopes or projectors classify under 9002 or 9031.
If for clock/watch or technical instrument use
Glass lenses specifically for timepieces or non-spectacle optical apparatus fall under Chapter 70 headings.

Import Tips & Compliance
• Include detailed coating specifications and durability test reports to demonstrate they remain spectacle lenses, not optical filters
• Ensure proper marking of prescription range (-12 to +8 diopters typical) and ensure single-unit entry if mass-produced for orthopedic correction
• Watch for undervaluation pitfalls; declare full value including coating process costs to prevent anti-dumping scrutiny

Uncoated Glass Spectacle Lenses
These are basic plano-convex or concave glass lenses made from optical crown glass, unmounted and designed specifically for use in prescription eyeglasses to correct refractive errors like myopia or hyperopia. They fall under HTS 9001.40.00.00 as spectacle lenses of glass that are optically worked but not mounted in frames. The lenses are produced through grinding and polishing processes to achieve precise curvature and surface quality for vision correction.
Photochromic Transition Glass Spectacle Lenses
Glass spectacle lenses that darken automatically when exposed to UV light, made from specially formulated photochromic glass like Corning Photogray, unmounted and ground to prescription specifications. They qualify under HTS 9001.40.00.00 as their primary function remains vision correction despite light-adaptive properties. These lenses offer convenience for indoor/outdoor use without separate sunglasses.
High-Index 1.8 Glass Lenses for Eyeglasses
Thin, lightweight high-index (1.8 refractive index) glass spectacle lenses designed for strong prescriptions, minimizing lens thickness while maintaining aberration-free vision. Made from dense flint glass and precisely polished, these unmounted lenses fit standard eyeglass frames. HTS 9001.40.00.00 applies to all optically worked glass spectacle lenses regardless of index or thinness.
Bifocal Glass Spectacle Lenses
Classic Kryptoc or flat-top bifocal glass lenses with distinct distance and near vision segments fused or molded into single unmounted lenses for presbyopia correction. Made from crown glass with precise segment lines, they require skilled optician edging. HTS 9001.40.00.00 includes multifocal spectacle lenses of glass as standard vision correction products.
Progressive Addition Glass Lenses
Varilux-style no-line progressive glass lenses providing seamless vision correction from distance through intermediate to near, with continuous power gradient ground into high-quality optical glass. These premium unmounted lenses minimize distortion through advanced freeform surfacing. Classified under HTS 9001.40.00.00 for all glass spectacle lenses including complex multifocals.
Trivex Glass Hybrid Spectacle Lenses
Impact-resistant glass lenses blending Trivex polymer core with glass outer layers for superior optical clarity and safety, designed for children's or sports eyeglasses. Optically worked to prescription with ANSI Z87.1 impact ratings. HTS 9001.40.00.00 applies if predominantly glass construction for spectacle use.
