HS v2017 Code: 290920

About ethers; cyclanic, cyclenic or cycloterpenic and their halogenated, sulphonated, nitrated or nitrosated derivatives

HS code 290920 covers a diverse range of organic chemical compounds known as ethers. These compounds play a crucial role in various industries, from pharmaceuticals and personal care products to specialty chemicals and solvents. As an important class of organic compounds, ethers with cyclanic, cyclenic, or cycloterpenic structures, and their halogenated, sulphonated, nitrated, or nitrosated derivatives, are widely used in the global chemical industry.

Production process

The production of the chemicals covered under HS code 290920 typically involves a series of chemical reactions and purification processes. The key steps often include the reaction of alcohols with alkyl halides or the dehydration of alcohols to form the desired ether compounds. Depending on the specific derivatives, additional steps such as halogenation, sulfonation, nitration, or nitrosation may be employed to introduce the desired functional groups.

Production inputs

The main inputs required for the production of the chemicals under HS code 290920 include a range of alcohols, alkyl halides, and other raw materials necessary for the various chemical reactions. Additionally, specialized equipment such as reactors, distillation columns, and purification systems are essential for the manufacturing process. Energy sources, such as electricity or steam, are also crucial inputs for the production facilities.

Production outputs

The chemicals covered under HS code 290920 are widely used as intermediates in the production of a variety of end-products. These ethers and their derivatives find applications in the manufacturing of 300410 (Medicaments (including veterinary medicaments), consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale), 330499 Cosmetic and toilet preparations, not elsewhere specified or included, 290531 (Ethylene glycol (ethanediol)), and other specialty chemicals. The outputs from this industry are often consumed by various downstream industries, contributing to the broader chemical and manufacturing sectors.
