Nitrites

HS v2017 Code: 283410

About nitrites

HS code 283410 covers the classification of nitrites, which are a group of chemical compounds that play a crucial role in various industries. Nitrites are salts of nitrous acid and are widely used as food preservatives, oxidizing agents, and in the production of other chemicals. They are an essential component in the manufacturing of dyes, explosives, and pharmaceuticals, making them a vital part of the global chemical industry.

Production process

The production of nitrites typically involves the reaction of nitrogen oxides with a base, such as sodium hydroxide or potassium hydroxide. This process results in the formation of sodium nitrite or potassium nitrite, which are the most common forms of nitrites used in commercial applications. The specific production techniques may vary depending on the desired end product and the scale of the operation.

Production inputs

The main inputs required for the production of nitrites include nitrogen oxides, such as nitric oxide (NO) or nitrogen dioxide (NO2), as well as the appropriate base (e.g., sodium hydroxide or potassium hydroxide). Additionally, the production process may require specialized equipment, such as reactors, distillation columns, and filtration systems, to ensure the efficient and safe manufacture of nitrites.

Production outputs

The primary output of HS code 283410 is nitrites, which are used in a variety of applications. These include 291500 food preservatives, 282000 oxidizing agents, and the production of 292100 dyes, 360100 explosives, and 300000 pharmaceuticals. Nitrites may also be used as intermediates in the synthesis of other chemical compounds, making them an important input for various downstream industries.
