Nitric acid; sulphonitric acids

HS v2017 Code: 280800

About nitric acid; sulphonitric acids

HS code 280800 covers the production and trade of nitric acid and sulphonitric acids. These inorganic chemicals are essential for a wide range of industrial processes and applications, making them a crucial component of the global chemical industry. Nitric acid, in particular, is a highly versatile compound used in the manufacture of fertilizers, explosives, dyes, and various other products. The sulphonitric acids, which are a combination of nitric and sulfuric acids, also have important industrial applications, such as in the production of certain pharmaceuticals and the processing of metals.

Production process

Nitric acid and sulphonitric acids are typically produced through the catalytic oxidation of ammonia. This process involves the reaction of ammonia with oxygen, which is then further oxidized to form nitric oxide. The nitric oxide is then absorbed in water, resulting in the formation of nitric acid. Sulphonitric acids are produced by combining nitric acid with sulfuric acid, creating a more concentrated and corrosive compound.

Production inputs

The main inputs required for the production of nitric acid and sulphonitric acids include ammonia, oxygen, and sulfuric acid. Specialized equipment, such as catalytic converters, absorption towers, and distillation units, are also necessary for the various stages of the production process. Additionally, the industry relies on a consistent supply of energy, typically in the form of electricity or steam, to power the manufacturing facilities.

Production outputs

The primary outputs of HS code 280800 are nitric acid and sulphonitric acids. These chemicals are widely used as intermediates in the production of a variety of other products, including 310210 Urea, 280920 Phosphoric acid, and 283510 (Phosphinates (hypophosphites), phosphonates (phosphites) and phosphates). The nitric acid and sulphonitric acids produced under this code are also consumed by industries such as 292221 Aminohydroxynaphthalenesulphonic acids and their sal, 291811 Lactic acid, its salts and esters, and 281511 (Sodium hydroxide (caustic soda), solid).
