HS v2022 Code: 2918

About acids; carboxylic acid with additional oxygen function and their anhydrides, halides, peroxides, peroxyacids; their halogenated, sulphonated, nitrated or nitrosated derivatives

HS code 2918 covers a diverse range of organic chemical compounds known as carboxylic acids with additional oxygen functions. These compounds play a crucial role in various industries, including pharmaceuticals, agrochemicals, and specialty chemicals. They are widely used as intermediates, solvents, and building blocks for the synthesis of more complex molecules. The global market for these products is driven by their versatility and growing demand across multiple sectors.

Production process

The production of the chemicals under HS code 2918 typically involves a series of chemical reactions, such as oxidation, esterification, and halogenation. Common methods include the oxidation of alcohols or aldehydes, the reaction of carboxylic acids with alcohols or halides, and the halogenation or nitration of existing carboxylic acid compounds. These processes are often carried out in controlled environments using specialized equipment and catalysts to ensure the desired purity and yield of the final products.

Production inputs

The main inputs required for the production of HS code 2918 chemicals include a variety of organic compounds, such as alcohols, aldehydes, and other carboxylic acids. Additionally, various reagents, solvents, and catalysts are necessary to facilitate the necessary chemical transformations. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the efficient and high-quality production of these chemicals.

Production outputs

The chemicals classified under HS code 2918 are widely used as intermediates and building blocks in the production of a wide range of other chemical products. They find applications in the manufacturing of pharmaceuticals, agrochemicals, dyes, and specialty chemicals. Some of the other HS codes that may consume the outputs of this industry include 2907 Phenols; phenol-alcohols, 2914 Ketones and quinones, whether or not with other oxygen function, and their halogenated, sulphonated, nitrated or nitrosated derivatives, and 2916 Carboxylic acids with unsaturated, alicyclic, aromatic or heterocyclic rings and their anhydrides, halides, peroxides, peroxyacids and their derivatives.
