Copper oxides and hydroxides

HS v2017 Code: 282550

About copper oxides and hydroxides

HS code 282550 covers copper oxides and hydroxides, which are important chemical compounds with a wide range of industrial applications. These compounds are essential raw materials for the production of various copper-based products, including pigments, catalysts, and copper salts. They play a crucial role in the metal processing, chemical, and electronics industries, contributing to the broader economy through their diverse uses.

Production process

Copper oxides and hydroxides are typically produced through the oxidation of copper metal or the precipitation of copper salts. The most common production methods involve the roasting of copper ores or the chemical treatment of copper-containing solutions to form the desired copper oxide or hydroxide compounds. These processes are carefully controlled to ensure the desired purity and composition of the final products.

Production inputs

The main inputs required for the production of copper oxides and hydroxides include copper metal, copper-containing ores or concentrates, and various chemical reagents such as acids, bases, and oxidizing agents. Additionally, specialized equipment like furnaces, reactors, and filtration systems are necessary for the various production steps.

Production outputs

The primary outputs of HS code 282550 are copper(II) oxide (CuO), copper(I) oxide (Cu2O), and copper hydroxide (Cu(OH)2). These compounds find applications in a wide range of industries, including 282519 Copper sulphates, 282530 Copper chlorides, and 282749 Copper salts of inorganic acids, where they are used as raw materials or intermediates in the production of other copper-based products.
