Iron or non-alloy steel; bars and rods, hot-rolled, hot-drawn or hot-extruded, containing indentations, ribs, grooves or other deformations produced during the rolling process or twisted after rolling

HS v2017 Code: 721420

About iron or non-alloy steel; bars and rods, hot-rolled, hot-drawn or hot-extruded, containing indentations, ribs, grooves or other deformations produced during the rolling process or twisted after rolling

HS code 721420 covers a critical category of steel products that are widely used in construction, infrastructure, and various industrial applications. These hot-rolled, hot-drawn, or hot-extruded steel bars and rods with deformations or twists are essential components in reinforced concrete, structural frameworks, and specialized equipment. Their importance in the global economy cannot be overstated, as they support the development of modern cities, transportation networks, and industrial facilities.

Production process

The production of HS code 721420 steel products 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 and deformed to create the desired profile, including indentations, ribs, grooves, or twists. The final products are then cooled, cut to length, and prepared for distribution.

Production inputs

The main inputs required for the production of HS code 721420 steel products include iron ore, coal, scrap steel, and various alloying elements such as manganese, chromium, and nickel. Specialized rolling mills, furnaces, and casting equipment are also essential for the manufacturing process. Additionally, skilled labor, energy, and transportation infrastructure are critical inputs that support the industry.

Production outputs

The primary outputs of HS code 721420 are deformed steel bars and rods, which are widely used in the construction industry as reinforcement for concrete structures. These products are also used in the manufacturing of machinery, agricultural equipment, and various industrial applications. Other related HS codes that may consume the output of 721420 include 7308 Structures and parts of structures, of iron or steel; plates, rods, angles, shapes, sections, tubes and the like, prepared for use in structures, of iron or steel, 7326 Other articles of iron or steel, and 8431 Parts suitable for use solely or principally with the machinery of headings 84.25 to 84.30.
