Lead, zinc and tin, unwrought

CPC v2.1 Code: 4144

About lead, zinc and tin, unwrought

cpc code 4144 covers the production and trade of lead, zinc, and tin in their unwrought forms. These base metals are essential raw materials for a wide range of industries, from construction and transportation to electronics and consumer goods. As key components in alloys, castings, and coatings, the global demand for these unwrought metals remains high, making this industry a vital part of the broader economy.

Production process

The production of unwrought lead, zinc, and tin typically involves mining, smelting, and refining processes. Ores containing these metals are extracted from the earth, then subjected to various thermal and chemical treatments to separate and purify the desired elements. Smelting techniques, such as blast furnaces and electrolytic processes, are used to extract the pure metals from their ores. Further refining may be done to improve the quality and purity of the final products.

Production inputs

The main inputs for the production of unwrought lead, zinc, and tin include the raw ores containing these metals, as well as energy sources, such as electricity and fuel, to power the smelting and refining equipment. Specialized machinery and equipment, such as furnaces, electrolytic cells, and casting molds, are also essential for the various production stages.

Production outputs

The primary outputs of cpc code 4144 are the unwrought forms of lead, zinc, and tin. These materials are then consumed by a variety of downstream industries, including 4145 Lead, zinc and tin, semi-manufactured, 4146 Copper, nickel, aluminum, unwrought, and 4147 Copper, nickel, aluminum, semi-manufactured, which use these base metals to create a wide range of products, from construction materials to electronic components.
