About iron or non-alloy steel; semi-finished products of iron or non-alloy steel, containing by weight 0.25% or more of carbon

HS code 720720 covers semi-finished products of iron or non-alloy steel containing 0.25% or more of carbon by weight. This type of steel is commonly used in a wide range of industrial applications, from construction and automotive manufacturing to machinery and equipment production. Its high carbon content gives it increased strength, hardness, and wear resistance, making it a crucial material in many sectors of the global economy.

Production process

The production of HS 720720 steel involves several key steps. First, iron ore, coal, and other raw materials are melted in a blast furnace to produce pig iron. The pig iron is then refined in a basic oxygen furnace or electric arc furnace to remove impurities and adjust the carbon content. The molten steel is then cast into semi-finished forms, such as billets, blooms, or slabs, which can be further processed into finished steel products.

Production inputs

The main inputs required for the production of HS 720720 steel include iron ore, coal, and other alloying elements such as manganese, chromium, and vanadium. Specialized equipment, such as blast furnaces, basic oxygen furnaces, and continuous casting machines, are also essential for the manufacturing process. Additionally, skilled labor and reliable energy sources are critical inputs for this industry.

Production outputs

HS 720720 steel is used to produce a variety of finished steel products, including 720810 Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, hot-rolled, not clad, plated or coated, 721310 Bars and rods, hot-rolled, in irregularly wound coils, of iron or non-alloy steel, and 721420 Bars and rods, of iron or non-alloy steel, not further worked than forged, hot-rolled, hot-drawn or hot-extruded, but including those twisted after rolling. These semi-finished steel products are then consumed by industries such as construction, automotive, and machinery manufacturing.
