HS v2017 Code: 721129

About iron or non-alloy steel; flat-rolled, cold-rolled, of a width less than 600mm, containing by weight 0.25% or more of carbon

HS code 721129 covers a specific type of iron or non-alloy steel product - flat-rolled, cold-rolled steel sheets and strips with a width less than 600mm, containing 0.25% or more carbon by weight. This type of steel is widely used in various industries, including automotive, construction, and manufacturing, due to its high strength, durability, and versatility. It plays a crucial role in the global economy, supporting the production of a wide range of goods and infrastructure.

Production process

The production of HS code 721129 steel involves a series of cold-rolling processes. First, the steel is heated and then passed through a series of rollers to reduce its thickness and increase its strength. The cold-rolling process can be repeated multiple times to achieve the desired thickness and properties. Finally, the steel is cut to the required width and length, often using specialized cutting equipment.

Production inputs

The main inputs required for the production of HS code 721129 steel include iron ore, coal, and other alloying elements such as manganese, chromium, and nickel. These raw materials are smelted in a blast furnace to produce crude steel, which is then further processed through the cold-rolling techniques. Additionally, the production process requires specialized machinery, such as rolling mills, cutting equipment, and quality control instruments.

Production outputs

The primary output of HS code 721129 is cold-rolled steel sheets and strips, which are then used in a wide range of applications. These steel products are often consumed by industries such as 721011 Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, hot-rolled, not clad, plated or coated, 721012 Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, hot-rolled, not clad, plated or coated, and 721049 Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, not further worked than hot-rolled, not clad, plated or coated, among others.
