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.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

9001.40.00.00Higher: 19.5% vs 17.5%

If multifocal after grinding

Ground multifocal lenses like bifocals or progressives fall under 9001.40.60 in Chapter 90.

7005.29.08Higher: 35% vs 17.5%

If float glass sheets cut to shape

Basic float glass sheets before lens-specific forming remain in 7005; cutting to shape doesn't change per notes.

7016.90.50Higher: 40% vs 17.5%

If paved or framed

Blanks assembled into paved glass spheres or with fittings move to 7016 for articles like labware.

Import Tips & Compliance

Include lab tests for refractive index to substantiate high-index claims and corrective purpose

Ensure customs declarations specify 'not optically worked' per chapter notes to maintain this classification

Watch for anti-reflective coatings; if applied, they may trigger reclassification if considered worked

Related Products 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.

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.
