3703.10 - In rolls of a width exceeding 610 mm:

This HTS category, 3703.10, specifically covers photographic paper, paperboard, and textiles that are sensitized but unexposed, and crucially, are presented in rolls with a width exceeding 610 mm. This broad classification encompasses a variety of sensitized media designed for image capture through photographic processes. The defining characteristic for inclusion here is the physical form: large format rolls of material.

Distinguishing this category from its siblings, 3703.20 and 3703.90, is essential for accurate classification. While 3703.20 addresses other photographic papers for color photography and 3703.90 encompasses all remaining "other" sensitized materials, 3703.10 is solely focused on the large roll format. Therefore, photographic papers or textiles, even if intended for color photography, would be classified elsewhere if they are not presented in rolls exceeding 610 mm in width.

Within this category, further distinctions are made based on the specific photographic medium. Subcategory 3703.10.30 applies to silver halide papers, which are a common type of photographic material sensitive to light through silver halide crystals. The residual products within this large roll format that do not fall under silver halide are classified under 3703.10.60.00, designated as "Other," ensuring a comprehensive classification for all qualifying sensitized goods in this specific presentation.
