3701.99 - Other:

This category, HTS 3701.99, encompasses photographic plates and films in flat form, sensitized and unexposed, made from materials other than paper, paperboard, or textiles. It also includes instant print film that meets these specifications, whether or not packaged. This designation serves as a residual category for flat sensitized photographic materials not specifically classified elsewhere within heading 3701.

Distinguishing this category from its sibling, 3701.91, is crucial. While 3701.91 specifically covers materials for color photography (polychrome), HTS 3701.99 is for all other types of flat sensitized photographic materials not intended for color reproduction. This means monochrome films and plates, as well as any specialized photographic materials that do not fall under the "polychrome" definition, would be classified here.

Within this category, further subdivisions exist to refine classification. The subcategory 3701.99.30.00 specifically addresses "Dry plates," which are photographic plates that are sensitive to light when dry. The remaining materials fall under the broader "Other" subcategory (3701.99.60), which would include various other forms of flat sensitized films and films for instant print photography not specifically defined as dry plates.
