2924.19 - Other:

This HTS category, 2924.19, encompasses acyclic amides and their derivatives, excluding those specifically enumerated elsewhere within the 2924.1 heading. This broad classification serves as a catch-all for acyclic carbamates and other acyclic amide-function compounds of carbonic acid that do not fall under more specific subheadings. The emphasis is on compounds where the amide group is attached to an acyclic carbon chain, distinguishing them from cyclic amides which are classified elsewhere.

Category 2924.19 differentiates itself from its sibling categories by focusing on amides that are not meprobamate (2924.11) nor specifically listed agrochemical compounds like fluoroacetamide, monocrotophos, or phosphamidon (2924.12). Therefore, classification within 2924.19 requires a careful assessment to ensure the compound is indeed acyclic and not one of the explicitly excluded items.

The subcategories within 2924.19 further refine the classification based on the specific chemical structure. Subheading 2924.19.11 is designated for general "Amides," indicating a primary focus on the amide functional group within the acyclic structure. Subheading 2924.19.80.00, titled "Other," serves as the residual category for any acyclic amide-function compounds of carbonic acid or their derivatives that do not fit the criteria for the more specific "Amides" subheading within this node.
