2922.39.10.00 - 2'-Amino aceto phenone; 3'-Amino aceto phenone; 1-Amino-4-bromo-2-methyl anthra quinone; 1,4-Bis [1-anthra quinonyl amino] anthra- quinone; 1,4-Di mesi dino anthra quinone; 4-Dimethyl amino benzaldehyde; and Imino di anthra quinone

This HTS category, 2922.39.10.00, encompasses a specific group of aromatic amino-quinones and amino-ketones that do not possess more than one type of oxygen function. The listed substances, including various amino acetophenones, brominated and dimethoxy substituted anthraquinones, dimethyl amino benzaldehyde, and imino di anthraquinone, are generally used as intermediates or specialized chemicals in the synthesis of dyes, pigments, and other complex organic compounds. The defining characteristic is the presence of both an amino group and a quinone or ketone functional group on an aromatic ring, with no other oxygen-containing functionalities present.

Distinguishing this category from its siblings is crucial for accurate classification. For instance, sibling categories 2922.39.05.00 and 2922.39.14.00 specifically enumerate other aromatic amino-quinones like 1-Amino-2,4-dibromoanthraquinone, 2-Amino-5-chlorobenzophenone, and 2-Aminoanthraquinone. Similarly, 2922.39.17.00 covers 1-Aminoanthraquinone. This subcategory, 2922.39.10.00, captures those aromatic amino-aldehydes, amino-ketones, and amino-quinones that are not explicitly listed under these specific sibling codes, provided they meet the general criteria of containing a single oxygen function.

As this is a leaf node, there are no further subcategories. Therefore, the classification of any aromatic amino-aldehyde, amino-ketone, or amino-quinone that does not fall under the more specifically enumerated sibling codes will be determined by its inclusion within this residual "Other" classification, contingent on it fitting the overarching definition of amino-quinones, amino-ketones, or amino-aldehydes with a single oxygen function. The precise identification and chemical structure are paramount for correct import and export declarations under this code.
