Iron or non-alloy steel; H sections, hot-rolled, hot-drawn or extruded, of a height of 80mm or more

HS v2017 Code: 721633

About iron or non-alloy steel; h sections, hot-rolled, hot-drawn or extruded, of a height of 80mm or more

HS code 721633 covers the production and trade of iron or non-alloy steel H-sections that are hot-rolled, hot-drawn, or extruded, with a height of 80mm or more. This type of steel product is widely used in the construction industry, as well as in the manufacturing of heavy machinery, equipment, and infrastructure. The demand for these steel H-sections is closely tied to the overall health of the global economy and the pace of industrial and infrastructure development.

Production process

The production of steel H-sections under HS code 721633 typically involves a multi-step process. First, raw materials such as iron ore, coal, and scrap steel are melted in a furnace to produce molten steel. The molten steel is then cast into semi-finished products, such as billets or blooms. These semi-finished products are then reheated and passed through a series of rolling mills, where they are shaped into the desired H-section profile. The final products may undergo additional heat treatment or finishing processes to meet specific customer requirements.

Production inputs

The main inputs required for the production of steel H-sections under HS code 721633 include iron ore, coal, scrap steel, and various alloying elements such as manganese, chromium, and nickel. Additionally, the industry relies on specialized rolling mills, furnaces, and other heavy machinery to facilitate the production process. Energy, in the form of electricity or natural gas, is another crucial input for the steel manufacturing industry.

Production outputs

The primary output of HS code 721633 is steel H-sections, which are used in a wide range of applications, including the construction of buildings, bridges, and other infrastructure. These steel products may also be consumed by the 731100 (Structures (incl. prefabricated buildings) of iron or steel) and 732690 Other articles of iron or steel industries, which use them as raw materials for the production of various metal structures and components.
