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

HS v2017 Code: 291211

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

HS code 291211 covers the production and trade of methanal, also known as formaldehyde. Formaldehyde is a vital chemical compound with a wide range of industrial and commercial applications. It is an essential building block for various products, including resins, adhesives, and disinfectants, making it a crucial component in many manufacturing processes across diverse sectors. Understanding the production, inputs, and outputs related to this HS code provides valuable insights into the global supply chain and the importance of this versatile chemical compound.

Production process

Formaldehyde is primarily produced through the catalytic oxidation of methanol. The process typically involves the following key steps: (1) Methanol is vaporized and mixed with air, (2) The methanol-air mixture is passed over a metal catalyst, usually silver or iron, (3) The catalytic reaction converts the methanol into formaldehyde, (4) The formaldehyde is then cooled, condensed, and purified to obtain the final product.

Production inputs

The main inputs required for the production of formaldehyde under HS code 291211 include methanol as the primary raw material, as well as catalysts such as silver or iron. Additionally, the process requires air, energy sources, and specialized equipment like reactors, condensers, and purification systems. The availability and cost of these inputs can significantly impact the overall production and supply of formaldehyde.

Production outputs

The primary output of HS code 291211 is formaldehyde, which is then used as an input for various downstream industries. Formaldehyde is a key component in the production of 390110 Polyethylene(390110) and 390120 Polyproplylene(390120) resins, as well as in the manufacture of 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials(392010). It is also used in the production of 380610 Rosin and resin acids, and derivatives thereof; rosin spirit and rosin oils; run gums(380610) and 380890 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, put up in forms or packings for retail sale or as preparations or articles(380890).
