Peroxosulphates (persulphates)

HS v2022 Code: 283340

About peroxosulphates (persulphates)

HS code 283340 covers peroxosulphates, also known as persulphates. These chemical compounds are widely used in various industries, including textiles, paper, and personal care products. They serve as oxidizing agents, initiators, and catalysts, playing a crucial role in numerous industrial processes. The peroxosulphates industry is an integral part of the broader chemical manufacturing sector, contributing to the overall economic development and supporting the operations of numerous downstream industries.

Production process

Peroxosulphates are typically produced through the reaction of sulfuric acid with hydrogen peroxide. This process involves the controlled oxidation of sulfate ions, resulting in the formation of the peroxosulfate compound. The specific production techniques may vary depending on the desired purity, concentration, and form of the final product, which can include crystalline, granular, or liquid formulations.

Production inputs

The main inputs required for the production of peroxosulphates include sulfuric acid, hydrogen peroxide, and various other chemicals and reagents used in the purification and formulation processes. Additionally, specialized production equipment, such as reactors, filtration systems, and drying units, are necessary to ensure the efficient and consistent manufacture of these chemical compounds.

Production outputs

The primary outputs of the peroxosulphates industry are the various forms of peroxosulfate compounds, including potassium peroxosulfate, sodium peroxosulfate, and ammonium peroxosulfate. These outputs are then consumed by a range of industries, such as 540000 Textile, 170000 Paper and paperboard, and 330000 Cosmetics and personal care products, where they are utilized as oxidizing agents, bleaching agents, and initiators in various manufacturing and processing applications.
