Products classified under HTS 7015.10.00.00
Unworked Polycarbonate Spectacle Blanks
These are curved, hollow polycarbonate blanks designed specifically for grinding into corrective spectacle lenses. They fall under HTS 7015.10.00.00 as glasses for corrective spectacles that are not optically worked, meaning they have not undergone final surfacing or polishing. The material is injection-molded into lens shapes prior to optical processing.
CR-39 Semi-Finished Lens Blanks
CR-39 resin blanks are pre-formed, curved glass-like lenses for corrective eyewear, awaiting optical working such as grinding to prescription. Classified in HTS 7015.10.00.00 as they are hollowed or curved but not yet optically finished. These allyl diglycol carbonate blanks are standard for everyday prescription glasses.
High-Index Glass Lens Blanks
These thin, lightweight glass blanks with high refractive index (1.60-1.74) are molded for progressive or bifocal corrective lenses before surfacing. They qualify under HTS 7015.10.00.00 as unworked glasses for spectacles, bent or hollowed but not optically processed. Ideal for strong prescriptions requiring minimal thickness.
Trivex Lens Blanks for Eyewear
Impact-resistant Trivex polymer blanks, optically clear and lightweight, formed into spectacle shapes for corrective grinding. Classified under HTS 7015.10.00.00 as glass equivalents (fused silica per notes) that are hollowed but unworked. Superior to polycarbonate for aberration control in prescriptions.
Bifocal Semi-Finished Glass Blanks
Glass blanks with pre-molded bifocal segments for distance and near vision correction, awaiting final grinding. HTS 7015.10.00.00 covers these bent, hollowed forms not optically worked. Common for reading and driving glasses.
Progressive Addition Lens Blanks
Blanks with seamless gradient zones for continuous vision correction, pre-formed but unground for spectacles. Under HTS 7015.10.00.00 as corrective glasses not optically worked, despite complex molding. Preferred for presbyopia without visible lines.
Polarization Spectacle Blanks
Curved blanks with polarizing film layers for glare reduction in corrective lenses, pre-surfacing. HTS 7015.10.00.00 as unworked corrective spectacle glass with bent form. Used in fishing or driving prescription sunglasses.
Mineral Glass Corrective Blanks
Crown glass blanks (soda-lime silicate) for high-clarity prescription lenses, hollowed and annealed but unworked. HTS 7015.10.00.00 for traditional spectacle glass forms. Scratch-resistant alternative to plastics.
Fused Quartz Spectacle Blanks
High-purity fused quartz blanks for specialized corrective optics, curved but unworked. Included as 'glass' per chapter notes in HTS 7015.10.00.00. Used in laser eye protection prescriptions.
Photochromic Spectacle Blanks
Pre-formed blanks embedded with photochromic molecules that darken in UV light, designed for transition corrective lenses prior to grinding. HTS 7015.10.00.00 applies as these curved blanks are not optically worked, retaining raw form for prescription surfacing. Used in everyday glasses that adapt to light conditions.
