Sulphates; of copper

HS v2022 Code: 283325

About sulphates; of copper

HS code 283325 covers the classification of copper sulphates, an essential inorganic chemical compound with a wide range of industrial and agricultural applications. Copper sulphates are produced globally and play a crucial role in various sectors, including agriculture, pharmaceuticals, electroplating, and water treatment, making them an important part of the broader chemical industry.

Production process

Copper sulphates are typically produced through the reaction of copper metal or copper oxide with sulphuric acid. The main production steps involve dissolving the copper source in the acid, filtering, and then crystallizing the copper sulphate. The resulting crystals are then dried and packaged for distribution.

Production inputs

The primary inputs for the production of copper sulphates are copper metal or copper oxide, sulphuric acid, and energy sources for the heating and drying processes. Additionally, specialized equipment such as reactors, filters, and crystallization tanks are required to facilitate the production.

Production outputs

The main output of HS code 283325 is copper sulphate, which can be used in a variety of applications. Some of the industries that may consume copper sulphate include 283326 Sulphates; of aluminium, 283329 Sulphates; other, 284020 Copper oxides and hydroxides, and 310420 Mineral or chemical fertilizers, potassic, among others.
