Nitrites

HS v2022 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 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 alkali metals or alkaline earth metals. This process can be carried out through various methods, including the direct reaction of nitrogen oxides with metal hydroxides or the reduction of nitrates. 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 alkali metals or alkaline earth metals, such as sodium, potassium, or calcium. Additionally, the production process may require various other chemicals, such as reducing agents, solvents, and catalysts, depending on the specific manufacturing method employed.

Production outputs

The primary output of HS code 283410 is nitrites, which can be used in a wide range of applications. Nitrites find use as food preservatives, where they help prevent the growth of harmful bacteria and maintain the color of cured meats. They are also used as oxidizing agents in the production of other chemicals, such as 282520 Calcium Hypochlorite and 282810 Chlorates. Additionally, nitrites are essential in the manufacturing of dyes, explosives, and certain pharmaceutical products.
