Sulphates; of aluminium

HS v2022 Code: 283322

About sulphates; of aluminium

HS code 283322 covers the classification of aluminium sulphates, a widely used chemical compound with diverse industrial applications. Aluminium sulphates are an essential ingredient in various manufacturing processes, playing a crucial role in industries such as water treatment, paper production, and chemical processing. As a versatile and cost-effective material, aluminium sulphates contribute significantly to the global economy, supporting the development of numerous downstream sectors.

Production process

Aluminium sulphates are typically produced through the reaction of aluminium hydroxide or aluminium oxide with sulphuric acid. The process involves dissolving the aluminium-based raw material in the acid, followed by evaporation and crystallization to obtain the desired aluminium sulphate product. Depending on the specific requirements, the production may also involve additional purification steps to ensure the desired purity and quality of the final product.

Production inputs

The main inputs required for the production of aluminium sulphates include aluminium hydroxide or aluminium oxide, sulphuric acid, and various other chemicals and reagents used in the purification and processing stages. Additionally, the industry relies on specialized equipment such as reactors, evaporators, and crystallizers to facilitate the manufacturing process. Energy sources, such as electricity or steam, are also essential for powering the production facilities.

Production outputs

The primary output of HS code 283322 is aluminium sulphate, which finds applications in a wide range of industries. Some of the key consumers of aluminium sulphates include the 282520 Water treatment industry, the 470200 Paper and pulp industry, and the 284700 Chemical manufacturing industry. Aluminium sulphates are also used in the production of other aluminium compounds, such as 283525 Aluminium hydroxide and 283526 Aluminium oxide, which are classified under different HS codes.
