3701.91.00.30 - Disc film

This HTS subcategory, 3701.91.00.30, specifically covers disc film designed for color photography. Disc film is characterized by its unique circular format, housing multiple exposures within a single disc. This classification applies to sensitized, unexposed film of any material other than paper, paperboard, or textiles, intended for producing color images when developed. It is distinct from other categories within 3701 primarily by its format and its dedicated use for polychrome (color) photographic processes.

Within the broader heading 3701, which encompasses flat photographic plates and film, this subcategory distinguishes itself from its sibling, 3701.91.00.60 ("Other"). The "Other" sibling would typically include any remaining sensitized, unexposed flat films not falling into more specific descriptions, such as black and white disc film (if such existed and wasn't covered elsewhere) or other less common flat film formats not specifically enumerated.

As this is a leaf node, there are no further subcategories. Therefore, the focus remains on accurately identifying disc film for color photography based on its physical characteristics and intended photographic output. Classification hinges on confirming the disc format and the film's inherent capability for polychrome reproduction, distinguishing it from general flat film or other photographic media.
