Ammonia; in aqueous solution

HS v2022 Code: 281420

About ammonia; in aqueous solution

HS code 281420 covers the classification of ammonia in aqueous solution, a critical industrial chemical with a wide range of applications. Ammonia is a colorless, pungent gas that is highly soluble in water, forming an alkaline solution. It is an essential component in the production of fertilizers, pharmaceuticals, and various other chemicals, making it a vital part of the global economy.

Production process

Ammonia in aqueous solution is primarily produced through the Haber-Bosch process, which involves the reaction of nitrogen and hydrogen gases under high temperature and pressure conditions. The resulting anhydrous ammonia is then dissolved in water to create the aqueous solution covered by this HS code.

Production inputs

The main inputs required for the production of ammonia in aqueous solution include natural gas or other hydrocarbon feedstocks as a source of hydrogen, as well as air or other nitrogen sources. Specialized equipment such as high-pressure reactors, compressors, and distillation columns are also essential for the Haber-Bosch process and subsequent dissolution in water.

Production outputs

Ammonia in aqueous solution is a widely used industrial chemical, with its primary applications in the production of 310210 Nitrogenous fertilizers and 281511 (Sodium hydroxide (caustic soda)) via the Solvay process. It is also an important precursor for the manufacture of various 284700 Compounds with nitrogen function, including pharmaceuticals and other specialty chemicals.
