2924.29.77 - Other

This HTS category, 2924.29.77, encompasses a broad range of carboxyamide and carbonic acid amide-function compounds that are cyclic in nature, along with their derivatives and salts. These compounds do not fall under the more specific subheadings within the cyclic amides section, nor are they exclusively designated by additional U.S. note 3 to section VI. The classification is intended for cyclic amides and carbamates and their related substances that do not have a unique or more precisely defined tariff heading.

The sibling category, 2924.29.71.00, is specifically reserved for products that meet the criteria outlined in additional U.S. note 3 to section VI. Therefore, this current category, 2924.29.77, is for all other cyclic amides and carbamates that are aromatic and do not fit the specifications of the sibling heading. The "Other" designation at this level signifies a residual classification for compounds not otherwise specified.

Within this category, further subdivisions exist to provide more granular classification based on specific chemical compounds. These subcategories include Acetoacetanilide (2924.29.77.10), Acetoacet-2,5-dimethoxy-4-chloroanilide (2924.29.77.20), and p-Aminobenzamide (2924.29.77.30), which represent specific aromatic cyclic amides. The final subheading, 2924.29.77.90, serves as a residual for any other aromatic cyclic amides and their derivatives not otherwise enumerated.
