Products classified under Tariff item 7015.10.00
Bifocal Semi-Finished Glass Blanks
Bifocal semi-finished glass blanks are pre-formed glass pieces with molded bifocal segments for distance and near vision correction. They are curved and hollowed but not yet optically worked, as they require final grinding to meet a prescription. These blanks fall under tariff item 7015.10.00 as glasses for corrective spectacles.
CR-39 Semi-Finished Lens Blanks
CR-39 resin lens blanks are pre-formed, curved blanks made from a glass-like plastic material, used for corrective eyewear. They are hollowed or curved but not optically worked, as they require grinding to a prescription. These blanks are classified under tariff item 7015.10.00 as glasses for corrective spectacles, despite being resin rather than traditional glass.
Fused Quartz Spectacle Blanks
Fused quartz spectacle blanks are high-purity fused silica blanks, curved but unworked, used for specialized corrective optics. Chapter note 5 defines glass to include fused quartz, so these blanks fall under tariff item 7015.10.00 as glasses for corrective spectacles. They are often used in laser eye protection prescriptions.
High-Index Glass Lens Blanks
High-index glass lens blanks are thin, lightweight glass blanks with a high refractive index (1.60-1.74), molded for progressive or bifocal corrective lenses. They are curved and hollowed but not optically worked, as they require surfacing. These blanks fall under tariff item 7015.10.00 as glasses for corrective spectacles.
Mineral Glass Corrective Blanks
Mineral glass corrective blanks are crown glass (soda-lime silicate) blanks for high-clarity prescription lenses. They are hollowed and annealed but unworked, making them suitable for tariff item 7015.10.00 as glasses for corrective spectacles. These blanks offer a scratch-resistant alternative to plastic lenses.
Photochromic Spectacle Blanks
Photochromic spectacle blanks are pre-formed blanks with photochromic molecules that darken in UV light, designed for transition corrective lenses. They are curved but not optically worked, as they require grinding to a prescription. These blanks fall under tariff item 7015.10.00 as glasses for corrective spectacles, retaining their classification despite the embedded photochromic properties.
Polarization Spectacle Blanks
Polarization spectacle blanks are curved blanks with polarizing film layers for glare reduction in corrective lenses, pre-surfacing. They are unworked and designed for corrective spectacles, falling under tariff item 7015.10.00 as glasses for corrective spectacles. These blanks are commonly used in driving or fishing prescription sunglasses.
Progressive Addition Lens Blanks
Progressive addition lens blanks are blanks with seamless gradient zones for continuous vision correction, pre-formed but unground for spectacles. They are curved and hollowed but not optically worked, as they require surfacing to a prescription. These blanks fall under tariff item 7015.10.00 as glasses for corrective spectacles, despite their complex molding.
Trivex Lens Blanks for Eyewear
Trivex lens blanks for eyewear are impact-resistant polymer blanks, optically clear and lightweight, formed into spectacle shapes for corrective grinding. They are curved and hollowed but not optically worked, qualifying under tariff item 7015.10.00 as glasses for corrective spectacles. Chapter note 5 includes fused silica, and Trivex is a glass-like material for this purpose.
Unworked Polycarbonate Spectacle Blanks
Unworked polycarbonate spectacle blanks are curved, hollow polycarbonate blanks designed for grinding into corrective spectacle lenses. They are not optically worked, meaning they have not been ground or polished to a prescription. These blanks fall under tariff item 7015.10.00 as glasses for corrective spectacles, as polycarbonate is considered a glass-like material for this heading.
