About fluorine, chlorine, bromine and iodine

HS code 2801 covers the group of halogen elements, including fluorine, chlorine, bromine, and iodine. These elements are essential in a wide range of industries, from chemical manufacturing to water treatment and pharmaceuticals. As primary building blocks for many compounds, the production and trade of these halogens play a crucial role in the global economy.

Production process

The primary production techniques for the halogens under HS code 2801 involve the electrolysis of their respective salts. For example, chlorine is typically produced by the electrolysis of sodium chloride (salt) solution, while fluorine is obtained through the electrolysis of hydrogen fluoride. Bromine and iodine are often extracted from natural brine sources or as by-products of other chemical processes.

Production inputs

The main inputs required for the production of the halogens under HS code 2801 include the respective mineral salts (e.g., sodium chloride, hydrogen fluoride), as well as electricity and specialized electrolysis equipment. Depending on the specific halogen, additional inputs such as water, catalysts, and purification systems may be necessary to ensure high-quality production.

Production outputs

The halogens produced under HS code 2801 are widely used as feedstock for the manufacture of a variety of chemical compounds, including 2812 Halides and halide oxides of nonmetals, 2901 Acyclic hydrocarbons, and 2903 Halogenated derivatives of hydrocarbons. These halogens are also directly consumed in industries such as water treatment, pharmaceuticals, and agriculture.
