HS v2022 Code: 290532

About alcohols; acyclic, diols; propylene glycol (propane-1, 2-diol)

HS code 290532 covers the classification of propylene glycol, a widely used organic compound with a diverse range of applications. As an acyclic diol, propylene glycol is a key ingredient in numerous industries, including pharmaceuticals, cosmetics, food and beverage production, and the manufacture of various chemicals. Its versatility and importance in the global economy make it a significant player within the broader chemical industry.

Production process

Propylene glycol is primarily produced through the hydration of propylene oxide, a process that involves the reaction of propylene with oxygen to form the epoxide, which is then hydrolyzed to yield propylene glycol. This production method is highly efficient and scalable, allowing for the large-scale manufacture of this essential chemical compound.

Production inputs

The main inputs required for the production of propylene glycol include propylene, a raw material derived from the refining of crude oil or natural gas, as well as water and various catalysts necessary for the hydration and hydrolysis processes. Additionally, specialized equipment, such as reactors, distillation columns, and purification systems, are essential for the efficient and high-quality production of propylene glycol.

Production outputs

The primary output of HS code 290532 is propylene glycol, which is then used as a key ingredient in a wide range of products, including 300000 Pharmaceutical products, 330000 Cosmetic and toiletry preparations, 220000 Beverages, spirits and vinegar, and various 290000 Organic chemicals.
