Sulphides; of sodium, whether or not chemically defined

HS v2022 Code: 283010

About sulphides; of sodium, whether or not chemically defined

HS code 283010 covers the classification of sodium sulphides, which are important chemical compounds used in a variety of industrial applications. As a key component in the production of other chemicals, dyes, and pharmaceuticals, the sodium sulphide industry plays a crucial role in supporting diverse sectors of the global economy.

Production process

Sodium sulphides are typically produced through the reaction of sodium hydroxide (lye) with hydrogen sulphide gas. This process involves carefully controlling temperature, pressure, and reaction time to ensure the desired chemical composition and purity of the final product.

Production inputs

The main inputs required for the production of sodium sulphides include sodium hydroxide, hydrogen sulphide, and energy sources to power the manufacturing process. Specialized equipment such as reaction vessels, distillation columns, and filtration systems are also necessary to facilitate the chemical synthesis and purification of the final product.

Production outputs

Sodium sulphides produced under HS code 283010 find application in the manufacture of 283620 Sulphites; of sodium and 283630 Thiosulphates, which are widely used in the textile, paper, and mining industries. Additionally, sodium sulphides serve as precursors for the production of other sodium-based chemicals, such as 283311 Disodium sulphate and 283319 Sulphates; of sodium, other than disodium sulphate.
