Chlorine

HS v2022 Code: 280110

About chlorine

HS code 280110 covers the classification of chlorine, a highly reactive and versatile chemical element. Chlorine is a critical industrial gas with a wide range of applications, from water treatment and disinfection to the production of various chemicals, plastics, and pharmaceuticals. It plays a vital role in the global economy, supporting industries that are essential for modern life.

Production process

Chlorine is primarily produced through the electrolysis of sodium chloride (salt) solution. This process involves passing an electric current through a brine solution, which separates the chloride ions and produces chlorine gas. The chlorine gas is then purified and compressed for storage and distribution.

Production inputs

The main inputs required for the production of chlorine include salt (sodium chloride), water, and electricity. Specialized equipment such as electrolysis cells, compressors, and storage tanks are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in chemical processing and plant operations.

Production outputs

The primary output of HS code 280110 is chlorine gas, which is then used as a feedstock for the production of a wide range of other chemicals and products. Some of the industries that consume chlorine include 290311 Chloromethanes, 290312 Dichloroethylene, 290321 Vinyl chloride, and 290322 Trichloroethylene. Chlorine is also used in water treatment, disinfection, and the manufacturing of various consumer goods.
