About basic iron and steel

cpc code 411 covers the basic iron and steel industry, a critical component of the global manufacturing and construction sectors. This industry is responsible for producing the raw materials that form the foundation of countless products, from automobiles and machinery to buildings and infrastructure. As a key driver of economic activity, the basic iron and steel industry plays a vital role in supporting economic growth and development worldwide.

Production process

The production of basic iron and steel involves several key steps. First, iron ore, coal, and other raw materials are extracted and processed. These materials are then fed into blast furnaces, where they are smelted at high temperatures to produce pig iron. The pig iron is further refined in basic oxygen furnaces or electric arc furnaces to remove impurities and create various steel products, such as ingots, billets, and slabs. These semi-finished steel products are then rolled, forged, or cast into a wide range of finished goods.

Production inputs

The basic iron and steel industry relies on a variety of raw materials and resources, including 2701 Coal, 2601 Iron ore, and 2704 Coke. Additionally, the industry requires significant energy inputs, such as electricity and natural gas, as well as specialized machinery and equipment for mining, smelting, and steel production.

Production outputs

The basic iron and steel industry produces a diverse range of outputs, including 7207 Semi-finished products of iron or non-alloy steel, 7208 Flat-rolled products of iron or non-alloy steel, and 7209 Flat-rolled products of iron or non-alloy steel. These semi-finished and finished steel products are then consumed by a wide range of industries, such as 29 Machinery and equipment n.e.c., 25 Fabricated metal products, except machinery and equipment, and 30 Other transport equipment.
