3703 - Photographic paper, paperboard and textiles, sensitized, unexposed:

This HTS category, 3703, encompasses photographic paper, paperboard, and textiles that have been sensitized with a light-sensitive emulsion but remain unexposed. These materials are specifically designed for use in photographic processes, distinguishing them from general printing papers or untreated textiles. The key characteristic is the presence of a chemical coating that reacts to light, forming the basis of an image.

When classifying under 3703, it's crucial to differentiate these goods from those in other chapters of Section VI. For instance, while Chapter 37 deals with photographic and cinematographic goods, other chapters may cover chemicals (Chapter 28, 29), or other types of paper, paperboard, or textiles that are not sensitized for photographic use. Within Chapter 37 itself, 3703 is distinct from finished photographic films or plates.

The subcategories within 3703 provide further refinement based on the format and type of photography. 3703.10 specifically addresses materials supplied in large rolls, indicating a commercial or industrial application. 3703.20 is for goods intended for color photography, implying a more complex chemical composition compared to black-and-white photographic materials. Finally, 3703.90 serves as a residual category for any other sensitized photographic paper, paperboard, or textiles that do not fit the more specific roll or color photography criteria.
