Sulphates; of aluminium

HS v2017 Code: 283322

About sulphates; of aluminium

HS code 283322 covers the classification of aluminium sulphates, an important group of inorganic compounds with a wide range of industrial applications. Aluminium sulphates are versatile chemicals that play a crucial role in various sectors, including water treatment, paper manufacturing, and the production of other aluminium-based compounds. As a key component in many industrial processes, the aluminium sulphates industry is an integral part of the broader chemical and manufacturing landscape.

Production process

Aluminium sulphates are typically produced through the reaction of aluminium hydroxide or aluminium oxide with sulphuric acid. The main production steps involve dissolving the aluminium-based raw material in sulphuric acid, followed by crystallization and purification to obtain the desired aluminium sulphate product. The specific production techniques may vary depending on the purity requirements and the intended applications of the final product.

Production inputs

The primary inputs for the production of aluminium sulphates include aluminium hydroxide or aluminium oxide, which serve as the source of aluminium, and sulphuric acid. Additionally, the production process may require various auxiliary materials, such as water, energy sources, and specialized equipment like reactors, crystallizers, and filtration systems.

Production outputs

The main output of HS code 283322 is aluminium sulphates, which find applications in a wide range of industries. These compounds are commonly used in water treatment processes, where they act as coagulants and flocculants to remove impurities. Aluminium sulphates are also utilized in the production of 470610 (Pulps of fibres derived from recovered (waste and scrap) paper or paperboard), as well as in the manufacture of 283525 Other aluminium compounds.
