Sulphates; of copper

HS v2017 Code: 283325

About sulphates; of copper

HS code 283325 covers the classification of copper sulphates, a widely used industrial chemical with diverse applications. Copper sulphates are essential compounds in various industries, including agriculture, electroplating, and the production of pigments and dyes. As a key input for numerous downstream sectors, the copper sulphates industry plays a vital role in the broader global economy.

Production process

Copper sulphates are typically produced through the reaction of copper metal or copper oxide with sulfuric acid. The main production methods involve the dissolution of copper in sulfuric acid, followed by crystallization and purification processes to obtain the desired copper sulphate product.

Production inputs

The primary inputs for the copper sulphates industry include copper metal or copper oxide, sulfuric acid, and various processing equipment such as reactors, evaporators, and crystallizers. Electricity and water are also essential resources required for the production of copper sulphates.

Production outputs

The main output of the copper sulphates industry is the copper sulphate compound, which is widely used in a variety of applications. The copper sulphates produced under this HS code may be consumed by industries such as 283326 Sulphates; of aluminium, 283327 Sulphates; of barium, and 283329 Sulphates; other than those of aluminium, copper or barium.
