Sodium sulphates; disodium sulphate

HS v2022 Code: 283311

About sodium sulphates; disodium sulphate

HS code 283311 covers the classification of sodium sulphates, including disodium sulphate. This inorganic chemical compound is a vital raw material for a wide range of industries, playing a crucial role in the global economy. It is used extensively in the production of various products, from detergents and glass to textiles and paper, making it an essential component in many manufacturing processes.

Production process

Sodium sulphates are typically produced through the reaction of sodium hydroxide or sodium carbonate with sulphuric acid. The resulting solution is then evaporated and crystallized to obtain the final product. This process can be further refined to produce higher purity grades of sodium sulphate, depending on the specific requirements of the end-use application.

Production inputs

The main inputs required for the production of sodium sulphates include sulphuric acid, sodium hydroxide or sodium carbonate, and energy sources for the evaporation and crystallization processes. Additionally, specialized equipment such as reactors, evaporators, and crystallizers are necessary to ensure efficient and high-quality production.

Production outputs

The primary output of HS code 283311 is sodium sulphates, which are then consumed by a wide range of industries. These include the 282520 Calcium carbonate, 282590 Other inorganic chemicals, 320110 Synthetic organic surface-active agents, and 320120 Synthetic organic surface-active preparations, among others. Sodium sulphates are essential for the production of various products, from detergents and glass to textiles and paper.
