Description

Overview

This HTS category, 2916, encompasses a specific group of organic chemicals characterized by their monocarboxylic acid structure, which are unsaturated and acyclic, or cyclic in nature. It includes not only the acids themselves but also their anhydrides, halides, peroxides, and peroxyacids, as well as any halogenated, sulfonated, nitrated, or nitrosated derivatives of these compounds. These substances are fundamentally organic acids where a single carboxyl group (-COOH) is attached to a carbon chain or ring, and the presence of double or triple bonds (unsaturation) or cyclic structures is a key defining feature.

Within the broader Chapter 29, which deals with organic chemicals, HTS code 2916 stands apart from sibling categories that cover different classes of organic compounds, such as amines, aldehydes, ketones, or alcohols. Unlike live animals in other sections of the HTS, this category is strictly focused on distinct chemical entities. It is important to differentiate 2916 from other carboxylic acid categories which may focus on saturated acyclic acids or dicarboxylic acids.

The subdivisions within 2916 further refine the classification based on the structure of the organic backbone. These include specific provisions for unsaturated acyclic monocarboxylic acids, their various derivatives, and a distinct subheading for cyclanic, cyclenic, or cycloterpenic monocarboxylic acids and their related compounds. Another key subdivision addresses aromatic monocarboxylic acids, their anhydrides, halides, peroxides, peroxyacids, and their derivatives, allowing for precise identification based on the presence of a benzene ring or other aromatic systems.
