Hydrogen chloride (hydrochloric acid)

HS v2022 Code: 280610

About hydrogen chloride (hydrochloric acid)

HS code 280610 covers the classification of hydrogen chloride, also known as hydrochloric acid. This inorganic chemical compound is a critical input for various industries, including chemical manufacturing, metal processing, and water treatment. As a high-volume commodity, the production and trade of hydrogen chloride play a significant role in the global economy.

Production process

Hydrogen chloride is primarily produced through the reaction of hydrogen gas and chlorine gas. This process, known as the Deacon process, involves the catalytic oxidation of hydrogen chloride to produce chlorine and water. The resulting hydrogen chloride is then purified and concentrated to produce the final hydrochloric acid product.

Production inputs

The main inputs required for the production of hydrogen chloride include hydrogen gas, chlorine gas, and various catalysts to facilitate the chemical reaction. Additionally, specialized equipment such as reactors, distillation columns, and storage tanks are necessary for the manufacturing process.

Production outputs

The primary output of HS code 280610 is hydrochloric acid, which is widely used in a variety of industries. Some of the key consumers of hydrochloric acid include 281511 Sodium hydroxide, 281512 Potassium hydroxide, and 281910 Hydrazine and hydroxylamine and their inorganic salts. Hydrochloric acid is also an essential input for the production of various other chemicals, such as those classified under HS codes 281810 Aluminium oxide, 281830 Aluminium hydroxide, and 282010 Manganese dioxide.
