Alkali or alkali-earth metals; sodium

HS v2017 Code: 280511

About alkali or alkali-earth metals; sodium

HS code 280511 covers the classification of sodium, a key alkali metal with a wide range of industrial and commercial applications. Sodium is an essential element in the production of various chemicals, materials, and consumer goods, making it a critical component in many global supply chains. Its versatility and importance in the broader economy underpin the significance of this HS code.

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 cathode and be deposited as pure sodium metal. The sodium is then collected and cast into ingots or other forms for further processing and distribution.

Production inputs

The main inputs required for the production of sodium under HS code 280511 include raw materials such as 251011 (Sodium chloride (rock salt)) and energy sources to power the electrolysis process. Specialized equipment, including electrolytic cells, cooling systems, and casting machinery, are also essential for the efficient and safe production of sodium.

Production outputs

Sodium produced under HS code 280511 is a versatile material with a wide range of applications. It is used in the production of various chemicals, such as 280519 Alkali or alkaline-earth metals; n.e.s.; rare-earth metals, 281512 (Sodium hydroxide (caustic soda), solid), and 283620 (Disodium carbonate (soda ash)) among others. Sodium is also a key component in the manufacture of certain metals, alloys, and glass products.
