Kodak Kodalith Halftone Screen
A precision photographic halftone screen made from high-resolution glass with fine line rulings, designed specifically for contact printing in engraving processes to create dot patterns for printing plates. It falls under HTS 9001.90.80.00 as a specialized optical element used in photographic halftone reproduction for graphic arts. The screen's ruled patterns enable the modulation of light to produce halftone images essential for offset lithography.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If projection-type for enlargers
Projection screens for photographic apparatus fall under heading 9010 as accessories for cameras or enlargers, not standalone optical elements.
If emulsion-coated photographic film
Screens with light-sensitive emulsions are classified as photographic plates/films in Chapter 37, excluding those purely as ruled optical aids.
If plastic sheet without optical ruling
Unruled plastic sheets for general drafting or printing are in Chapter 39 as other plastic plates, not specialized optical halftone screens.

Import Tips & Compliance
• Verify screen ruling density (e.g
• 65-150 lines/inch) and material composition in documentation to confirm classification under optical elements for photographic processes
• Include technical specs showing use in engraving or halftone photography; avoid general 'screen' labeling to prevent misclassification as printing accessories
