HS v2022 Code: 291712

About acids; acyclic polycarboxylic acids; adipic acid, its salts and esters

HS code 291712 covers the production and trade of adipic acid, a vital chemical compound used in the manufacturing of various products. Adipic acid is a dicarboxylic acid that serves as a key raw material for the production of nylon, polyurethanes, and other important industrial and consumer goods. This code is significant within the broader chemical industry, as adipic acid is a crucial building block for a wide range of applications across numerous sectors, including plastics, textiles, and automotive components.

Production process

The primary production method for adipic acid involves the oxidation of cyclohexanol or cyclohexanone, which are derived from benzene. This process typically takes place in a series of reactors, where the raw materials are combined with air or oxygen under controlled temperature and pressure conditions. The resulting adipic acid is then purified through crystallization, filtration, and drying processes to meet the required quality standards for various end-uses.

Production inputs

The main inputs for the production of adipic acid under HS code 291712 include benzene, cyclohexanol, cyclohexanone, and various catalysts and reagents used in the oxidation and purification stages. Additionally, the industry requires specialized equipment such as reactors, distillation columns, and centrifuges to facilitate the production and refining processes. Energy sources, such as electricity and steam, are also crucial inputs for the efficient operation of the manufacturing facilities.

Production outputs

The primary output of HS code 291712 is adipic acid, which is then used as a feedstock for the production of a wide range of downstream products. These include 54023 Synthetic filament yarn, 39073 Polyurethanes, and 40021 Synthetic rubber and factice derived from oils, among others. Adipic acid is also used in the manufacture of plasticizers, lubricants, and various other chemical intermediates that are essential for numerous industries.
