Sulphates; of nickel

HS v2017 Code: 283324

About sulphates; of nickel

HS code 283324 covers the classification of sulphates of nickel. Nickel sulphates are important industrial chemicals with a wide range of applications, including use in electroplating, battery manufacturing, and as catalysts. This industry plays a crucial role in the broader metal processing and chemical manufacturing sectors, supporting various downstream industries that rely on nickel-based products.

Production process

Nickel sulphates are typically produced through the chemical reaction of nickel metal or nickel oxide with sulphuric acid. The main production steps involve dissolving the nickel-containing raw material in the acid, purifying the resulting solution, and then crystallizing the nickel sulphate. Depending on the desired purity and application, additional refining and processing steps may be employed.

Production inputs

The primary inputs for the production of nickel sulphates include nickel metal or nickel oxide, sulphuric acid, and various processing chemicals and equipment. Nickel is the key raw material, which can be sourced from nickel mining and refining operations. Sulphuric acid is a widely available industrial chemical, while other inputs may include filtration media, evaporation and crystallization equipment, and utilities such as water and energy.

Production outputs

The main output of this industry is nickel sulphate, which is then used in a variety of downstream applications. Some of the key consumers of nickel sulphate include the 284700 Nickel compounds industry, the 284410 Cobalt oxides and hydroxides; commercial cobalt oxides industry, and the 284450 Inorganic base metals salts and peroxysalts, n.e.c. industry. Nickel sulphate is also an important input for the 284610 Precious metal compounds industry.
