3707.10.00 - Sensitizing emulsions

HTS Code 3707.10.00 specifically classifies sensitizing emulsions. These are chemical preparations designed to impart photosensitivity to materials, primarily used in the manufacturing of photographic paper and films. Their function is to react with light to form a latent image.

This category is distinct from its sibling, 3707.90, which covers "Other" chemical preparations for photographic uses that do not fall under the specific sensitizing emulsion classification. While both fall under the broader chapter of photographic goods, 3707.10.00 is dedicated to the core light-sensitive component itself.

The subcategories within 3707.10.00 differentiate based on application. 3707.10.00.05 is reserved for sensitizing emulsions specifically intended for use in the production of color negative photographic paper, highlighting a specialized end-use. The residual category, 3707.10.00.90, captures all other sensitizing emulsions not otherwise specified, ensuring comprehensive coverage for this type of photographic chemical.
