Alkali or alkali-earth metals; sodium
HS v2022 Code: 280511
About alkali or alkali-earth metals; sodium
HS code 280511 covers the classification of sodium, a critical alkali metal that plays a vital role in various industries and everyday life. Sodium is an essential element for many chemical processes and is widely used in the production of a diverse range of products, from glass and ceramics to pharmaceuticals and cleaning agents. Its importance in the global economy cannot be overstated, as it is a key component in numerous supply chains and manufacturing processes.
Production process
Sodium is primarily produced through the electrolysis of molten sodium chloride (common salt). This process involves passing an electric current through the molten salt, which causes the sodium ions to migrate to the negative electrode, where they are then collected and solidified. The resulting pure sodium metal is then further refined and processed for various applications.
Production inputs
The main inputs required for the production of sodium under HS code 280511 include raw materials such as rock salt or brine, as well as specialized electrolysis equipment and a reliable source of electricity. Additionally, the production process may require other supporting materials, such as catalysts, protective gases, and various processing aids.
Production outputs
The primary output of HS code 280511 is pure sodium metal, which is then used as a key ingredient or intermediate in the manufacture of a wide range of products. These include 280519 Alkali or alkaline-earth metals, 282520 Calcium oxide and hydroxide, 283650 Sodium hydrides, nitrides, azides, silicides and borides, and 284700 Hydrogen peroxide, among others.
