About iron; non-alloy pig iron containing by weight 0.5% or less of phosphorus, in pigs, blocks or other primary forms

HS code 720110 covers non-alloy pig iron, a crucial raw material in the steel industry. Pig iron is the primary product of the iron blast furnace and serves as the base material for a wide range of steel and cast iron products. This industry plays a vital role in the global manufacturing and construction sectors, supporting the production of essential infrastructure, machinery, and consumer goods.

Production process

The production of non-alloy pig iron (720110) involves the smelting of iron ore in a blast furnace. Iron ore, along with coke and limestone, is charged into the top of the furnace, where it is heated to extremely high temperatures. This process reduces the iron ore, separating the iron from impurities such as silica and alumina. The molten iron is then tapped from the bottom of the furnace and cast into molds, forming the characteristic pig iron 'pigs' or blocks.

Production inputs

The main inputs for the production of non-alloy pig iron (720110) are iron ore, coke (a refined coal product), and limestone. These raw materials are essential for the chemical reactions that take place in the blast furnace. Additionally, the process requires significant energy inputs, typically in the form of electricity or natural gas, to power and heat the furnace. Specialized equipment, such as blast furnaces, casting molds, and material handling systems, are also crucial inputs for this industry.

Production outputs

The primary output of HS code 720110 is non-alloy pig iron, which is then further processed into a wide range of steel and cast iron products. These include 720211 Ferro-manganese, 720221 Ferro-silicon, 720310 Ferrous products obtained by direct reduction of iron ore, and 720410 Ferrous waste and scrap; remelting scrap ingots of iron or steel. Pig iron is an essential input for the production of these downstream steel and iron-based goods, which are used in various industries, such as construction, automotive, machinery, and consumer goods manufacturing.
