2924.19.11 - Amides

This HTS category, 2924.19.11, specifically covers acyclic amides and their derivatives, excluding those of carbonic acid, that do not fall under more specific subheadings within the broader acyclic amides group. It encompasses compounds characterized by the presence of an amide functional group (-CONH2, -CONHR, or -CONR2) where the acyl group is derived from an acyclic carboxylic acid or a related derivative. These substances are typically organic chemicals with diverse industrial applications, ranging from intermediates in chemical synthesis to components in polymers and pharmaceuticals.

The distinction of this subheading from its sibling, 2924.19.80 (Other), lies in the established and enumerated classifications within 2924.19.11. While 2924.19.80 serves as a residual category for acyclic amides not otherwise specified, 2924.19.11 captures specific, commonly traded acyclic amide compounds that warrant their own distinct classification. Therefore, the selection of 2924.19.11 requires the identification of the specific chemical nature of the acyclic amide in question.

Within this category, further subdivision is provided to account for key acyclic amides: 2924.19.11.10 for Acrylamide, 2924.19.11.20 for Dimethylformamide, and 2924.19.11.30 for Methacrylamide. These specific entries recognize the significant commercial importance and distinct chemical properties of these particular compounds. The residual subheading 2924.19.11.50 exists to capture any other acyclic amides that fit the broader scope of 2924.19.11 but are not individually listed.
