Complex cyanides

HS code 283720 covers complex cyanides, which are a class of chemical compounds consisting of a central metal atom bonded to multiple cyanide groups. These compounds play a crucial role in various industrial processes, from metal plating and electroplating to the production of pharmaceuticals and agricultural chemicals. As a key component in many manufacturing and processing activities, complex cyanides are an essential part of the global import/export trade.

The production of complex cyanides typically involves the reaction of a metal salt with a cyanide source, such as sodium cyanide or potassium cyanide. The specific production techniques can vary depending on the desired final product, but often include steps like dissolution, precipitation, filtration, and drying to obtain the pure compound.

The main inputs required for the production of complex cyanides include metal salts (e.g., 282520 Calcium chloride, 282739 Sodium cyanide, 282735 Potassium cyanide), as well as specialized equipment like reactors, filters, and drying chambers. Depending on the application, additional inputs like solvents or catalysts may also be required.

Complex cyanides produced under HS code 283720 are used in a wide range of industries, including 285000 Organo-inorganic compounds, 284700 Inorganic and organic compounds of precious metals, and 284390 Other inorganic compounds. These compounds are often further processed or incorporated into final products, making them an important input for various downstream industries.
