Paraformaldehyde

HS v2022 Code: 291260

About paraformaldehyde

HS code 291260 covers paraformaldehyde, a chemical compound that is widely used in various industries. As a solid polymer of formaldehyde, paraformaldehyde is an important intermediate in the production of many other chemicals and materials. It plays a crucial role in the manufacturing of resins, adhesives, and disinfectants, making it a vital component in the broader chemical industry and its associated supply chains.

Production process

Paraformaldehyde is typically produced through the polymerization of formaldehyde. This process involves the controlled condensation of formaldehyde gas, which is then dried and compacted into a solid, granular form. The specific production techniques may vary depending on the desired purity, particle size, and other properties of the final product.

Production inputs

The main inputs required for the production of paraformaldehyde include formaldehyde gas, which serves as the primary raw material. Additionally, the manufacturing process may require specialized equipment, such as polymerization reactors, drying systems, and compaction machinery. Energy sources, such as electricity or steam, are also necessary to power the various stages of production.

Production outputs

The primary output of HS code 291260 is paraformaldehyde, which is then consumed by various downstream industries. Some of the key industries that utilize paraformaldehyde include the 320611 Paints and Varnishes, 350510 Adhesives, and 380810 Disinfectants and Pesticides sectors, where it is used as a raw material or intermediate in the production of their respective products.
