Products classified under Tariff item 70.14
BK7 Glass Lens Blank for Camera Objectives
A BK7 optical glass blank cut to a circular shape, intended for grinding into camera lens elements. It is not optically worked, meaning it has not undergone grinding or polishing to achieve its final optical surface. This places it under tariff item 7014.00.00 as an optical element of glass, other than those of heading 70.15.
7014.00.00Borosilicate Lens Blank for Fiber Optic Couplers
A borosilicate glass blank for GRIN lenses used in fiber optic couplers, cut to a rod lens shape. The blank is not optically worked, as it has not been ground or polished to its final optical specifications. It qualifies under tariff item 7014.00.00 as an unworked optical element of glass.
7014.00.00Calcium Fluoride Lens Blank for IR Spectroscopy
A calcium fluoride (CaF2) crystalline blank for infrared spectrometer lenses, machined but not polished. Although CaF2 is crystalline, it is treated as glass for tariff purposes under Chapter 70 note 5. As an unworked optical element, it falls under tariff item 7014.00.00.
7014.00.00Collimating Lenses for Lasers
Rough-cut glass lenses designed to collimate laser beams in scientific instruments, not optically worked. These lenses are shaped but have not undergone grinding or polishing for optical performance. They fall under tariff item 7014.00.00 as other optical elements of glass that are not optically worked.
7014.00.00Dense Barium Crown Glass Lens Blank for Scanners
A dense barium crown (DBC) glass blank for flatbed scanner CIS lenses, precision cut to shape. The blank is not optically worked, as it has not been ground or polished for optical performance. It falls under tariff item 7014.00.00 as an unworked optical element of glass.
7014.00.00Extra-White Float Glass Lens Blank for Projectors
An extra-white float glass blank for projector Fresnel lenses, cut to shape with low iron content for high transmission. Per Chapter 70 note 2(b), cutting to shape does not affect classification in glass sheets, and the blank is not optically worked. It qualifies under tariff item 7014.00.00 as an unworked optical element.
7014.00.00Fused Quartz Lens Blank for Semiconductor Lithography
An ultra-pure fused quartz blank for 193nm lithography stepper lenses. Fused quartz is considered glass per Chapter 70 note 5, and the blank is not optically worked. It falls under tariff item 7014.00.00 as an unworked optical element of glass.
7014.00.00Fused Silica Lens Blank for UV Optics
A precision-machined fused silica blank for UV optical systems, such as lithography machines. The blank is not optically worked, as it has not been ground or polished to final optical specifications. It falls under tariff item 7014.00.00 as an unworked optical element of fused silica glass.
7014.00.00LaSFN9 Lanthanum Flint Lens Blank for Binoculars
A LaSFN9 high-index glass blank for binocular eyepiece lenses, shaped but not optically worked. The blank is not ground or polished for optical performance, so it falls under tariff item 7014.00.00 as an unworked optical element of glass, excluding spectacle lenses.
7014.00.00N-BK7 Lens Blank for Projection Systems
An N-BK7 crown glass circular blank for DLP projector condenser lenses, pre-annealed but not surfaced. The blank is not optically worked, as it has not been ground or polished for optical performance. It falls under tariff item 7014.00.00 as an unworked optical element of glass.
7014.00.00Precision Ground Lens Blank for Microscope Objectives
A high-precision borosilicate glass blank for microscope objective lenses, pre-cut but not surfaced optically. The blank is not optically worked, as it has not been ground or polished for optical performance. It falls under tariff item 7014.00.00 as an unworked optical element of glass.
7014.00.00P-SF67 High-Dispersion Glass Lens Blank for Cameras
A P-SF67 flint glass blank for apochromatic camera lenses, used to correct chromatic aberration. The blank is not optically worked, as it has not been ground or polished for optical performance. It falls under tariff item 7014.00.00 as an unworked optical element of glass.
7014.00.00Quartz Lens Blank for Laser Systems
A synthetic quartz glass blank for high-power laser focusing lenses, not yet optically figured. The blank is not optically worked, as it has not been ground or polished for optical performance. It falls under tariff item 7014.00.00 as an unworked optical element of fused silica glass.
7014.00.00Schott N-LAF33 Lens Blank for Medical Endoscopes
An N-LAF33 lanthanum flint blank for rigid endoscope objective lenses. The blank is not optically worked, as it has not been ground or polished for optical performance. It falls under tariff item 7014.00.00 as an unworked optical element of glass.
7014.00.00SF11 Dense Flint Glass Lens Blank for Telescopes
An SF11 optical flint glass blank for achromatic telescope objectives, cut to shape but unpolished. The blank is not optically worked, as it has not been ground or polished for optical performance. It falls under tariff item 7014.00.00 as an unworked optical element of glass.
