Alcohols; acyclic, diols; ethylene glycol (ethanediol)

HS v2022 Code: 290531

About alcohols; acyclic, diols; ethylene glycol (ethanediol)

HS code 290531 covers the classification of ethylene glycol, a widely used organic compound with a diverse range of industrial and commercial applications. As a key component in the production of antifreeze, coolants, and various chemical intermediates, ethylene glycol plays a vital role in the global economy, supporting industries from automotive to pharmaceuticals.

Production process

Ethylene glycol is primarily produced through the hydration of ethylene oxide, a process that involves the reaction of ethylene with water under controlled temperature and pressure conditions. The resulting ethylene glycol is then purified and refined to meet the specific requirements of its intended applications.

Production inputs

The production of ethylene glycol requires several key inputs, including ethylene, a feedstock derived from the petrochemical industry, as well as water, catalysts, and energy sources to power the manufacturing process. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the efficient and high-quality production of this versatile chemical compound.

Production outputs

Ethylene glycol, classified under HS code 290531, is a widely used chemical with a diverse range of applications. It is a key ingredient in the production of 381120 Antifreeze preparations and de-icing fluids, 390720 Polyethers, in primary forms, and various other chemical intermediates. The output of this industry is often consumed by industries such as automotive, construction, and pharmaceuticals, highlighting the importance of ethylene glycol in supporting the broader economy.
