Aldehydes; acyclic, without other oxygen function, methanal (formaldehyde)

HS v2022 Code: 291211

About aldehydes; acyclic, without other oxygen function, methanal (formaldehyde)

HS code 291211 covers the production and trade of acyclic aldehydes without other oxygen functions, with a focus on methanal (formaldehyde). This chemical compound is a vital raw material for a wide range of industries, including construction, automotive, and healthcare. Its versatility and importance in the global economy make it a significant player in the international import/export market.

Production process

Formaldehyde is primarily produced through the catalytic oxidation of methanol. This process involves the reaction of methanol with oxygen in the presence of a catalyst, typically silver or metal oxide, to yield formaldehyde. The reaction takes place at elevated temperatures, and the resulting formaldehyde is then purified and concentrated for commercial use.

Production inputs

The main inputs required for the production of formaldehyde include methanol, which serves as the primary raw material, as well as oxygen and a suitable catalyst. Additionally, the production process requires specialized equipment, such as reactors, distillation columns, and storage tanks, to facilitate the chemical reaction and purification of the final product.

Production outputs

Formaldehyde, the primary output of HS code 291211, is a versatile chemical with a wide range of applications. It is used as a raw material in the production of various resins, plastics, and adhesives, which are then consumed by industries such as 392010 Plastics and 441510 Wood furniture. Formaldehyde is also used in the manufacture of certain pharmaceuticals and as a disinfectant and preservative in various products.
