2925.19 - Other:

This HTS category, 2925.19, encompasses imides and their derivatives, as well as their salts, that are not specifically enumerated in the preceding subcategories. It broadly covers compounds characterized by the presence of an imide functional group, which involves a carbonyl group bonded to two amine groups. This classification serves as a residual category for imide-containing substances that do not fall under the more specific classifications.

Distinguishing this category from its siblings is crucial for accurate classification. HTS 2925.11.00.00 specifically covers saccharin and its salts, a well-known artificial sweetener. Similarly, HTS 2925.12.00.00 is designated for glutethimide (INN), a pharmaceutical compound. Therefore, 2925.19 applies to all other imide derivatives and salts that do not fit these particular descriptions.

The subcategories under 2925.19 further refine the classification based on the chemical structure of the imide. The "Aromatic:" subdivision will house imides where the imide group is attached to an aromatic ring system, influencing their chemical properties and potential applications. The "Other:" subdivision will then cover all remaining imides and their derivatives that are not aromatic in nature. This hierarchical structure ensures precise placement of diverse chemical compounds within the HTS.
