Iron or non-alloy steel; U, I or H sections, hot-rolled, hot-drawn or extruded, of a height of less than 80mm

HS v2017 Code: 721610

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

HS code 721610 covers the production and trade of iron or non-alloy steel U, I, or H sections that are hot-rolled, hot-drawn, or extruded, with a height of less than 80mm. This industry is a crucial component of the broader steel and metal manufacturing sector, providing essential raw materials and semi-finished products for a wide range of downstream industries, including construction, automotive, and machinery manufacturing.

Production process

The production of the steel sections described by HS code 721610 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 ingots or continuous cast into 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 U, I, or H cross-sections. Finally, the steel sections may undergo additional heat treatment or finishing processes to meet specific customer requirements.

Production inputs

The main inputs required for the production of HS code 721610 steel sections include iron ore, coal, scrap steel, and other alloying elements such as manganese, chromium, or nickel. Additionally, the industry relies on specialized rolling mills, furnaces, and other metal-working machinery and equipment. Energy, such as electricity and natural gas, is also a significant input for the production process.

Production outputs

The steel sections produced under HS code 721610 are primarily used as structural components in the construction industry, as well as in the manufacturing of machinery, vehicles, and other metal-intensive products. The output of this industry may be consumed by industries classified under codes such as 730120 Structures and parts of structures, of iron or steel; towers and lattice masts, 730830 Structures and parts of structures, of iron or steel; doors, windows and their frames and thresholds for doors, and 870120 (Motor vehicles for the transport of goods; other, with compression-ignition internal combustion piston engine (diesel or semi-diesel)), among others.

Revisions to 721610
