Iron or non-alloy steel; U, I or H sections, hot-rolled, hot-drawn or extruded, of a height of less than 80mm
HS v2022 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 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 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 and natural gas, is also a significant input for this industry.
Production outputs
The steel sections produced under HS code 721610 are primarily used as structural components in the construction industry, where they are used in the framing of buildings, bridges, and other infrastructure. They are also consumed by the automotive industry for the production of vehicle frames and other structural parts, as well as the machinery manufacturing sector for the fabrication of various equipment. Other potential consumers of these steel sections include the shipbuilding, railway, and agricultural equipment industries. The output of HS code 721610 may also be further processed and incorporated into products classified under other HS codes, such as 730120 Structures and parts of structures, of iron or steel; plates, rods, angles, shapes, sections, tubes and the like, prepared for use in structures, 730890 Structures and parts of structures, of iron or steel, n.e.c. in heading no. 7308, and 731010 (Tanks, casks, drums, cans, boxes and similar containers, for any material (other than compressed or liquefied gas), of iron or steel, of a capacity not exceeding 300l, not fitted with mechanical or thermal equipment).
Revisions to 721610
