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, making it an essential component in the production of numerous consumer and industrial goods. As a key input for various chemical processes, the chlorine industry plays a vital role in the broader manufacturing and chemical sectors, contributing significantly to the global economy.

Chlorine is primarily produced through the electrolysis of sodium chloride (salt) solution, a process known as the chlor-alkali process. In this method, an electric current is passed through a brine solution, causing the sodium chloride to split into chlorine gas, hydrogen gas, and sodium hydroxide. The chlorine gas is then purified and liquefied for storage and distribution.

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 chlor-alkali process. Additionally, the industry relies on a range of supporting materials, including piping, valves, and instrumentation to ensure the safe and efficient handling of the chlorine gas.

The primary output of the chlorine industry is, of course, chlorine gas. This versatile chemical is widely used as a disinfectant, in the production of 280490 Hydrogen, rare gases and other non-metals, 290311 Chloromethanes, and 290312 (Dichloromethane (methylene chloride)), among other applications. Chlorine is also a key input for the production of 380810 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, 390390 Other polymers of vinyl chloride or of other halogenated olefins, in primary forms, and 281512 Calcium hypochlorite and other inorganic oxygen compounds of chlorine.
