HS v2022 Code: 290943

About ether-alcohols and their halogenated, sulphonated, nitrated or nitrosated derivatives; monobutyl ethers of ethylene glycol or of diethylene glycol

HS code 290943 covers a range of organic chemical compounds known as ether-alcohols and their derivatives. These substances play a crucial role in various industries, including pharmaceuticals, cosmetics, and specialty chemicals. As an important part of the broader organic chemicals sector, this code represents a significant segment of international trade and economic activity.

Production process

Ether-alcohols and their derivatives are typically produced through a series of chemical reactions. The primary production method involves the etherification of alcohols, where an alcohol group is combined with an ether group to form the desired ether-alcohol compound. This process may be followed by additional steps, such as halogenation, sulphonation, nitration, or nitrosation, to create the various derivatives covered under this code.

Production inputs

The main inputs required for the production of ether-alcohols and their derivatives include alcohols, such as ethylene glycol or diethylene glycol, as well as various halogenating, sulphonating, nitrating, or nitrosating agents. Specialized chemical processing equipment, such as reactors, distillation columns, and purification systems, are also essential for the manufacturing process.

Production outputs

The ether-alcohols and their derivatives produced under HS code 290943 have a wide range of applications. They are commonly used as solvents, intermediates, and additives in the production of pharmaceuticals, cosmetics, paints, and other specialty chemicals. The outputs from this industry may be further processed or incorporated into the manufacturing of 300000 Pharmaceutical products, 330000 Perfumes, cosmetics, and toiletries, and 320000 Tanning or dyeing extracts; tannins and their derivatives; dyes, pigments and other coloring matter; paints and varnishes; putty and other mastics; inks.
