Iron or non-alloy steel; bars and rods, hot-rolled, hot-drawn or hot-extruded, including those twisted after rolling, of free-cutting steel

HS v2017 Code: 721430

About iron or non-alloy steel; bars and rods, hot-rolled, hot-drawn or hot-extruded, including those twisted after rolling, of free-cutting steel

HS code 721430 covers a crucial segment of the steel industry, encompassing the production of iron or non-alloy steel bars and rods. These hot-rolled, hot-drawn, or hot-extruded products, including those twisted after rolling, are commonly referred to as 'free-cutting steel'. This type of steel is highly valued for its machinability and is widely used in various manufacturing processes, making it an essential component of the global industrial landscape.

Production process

The production of free-cutting steel bars and rods under HS code 721430 typically involves a multi-step process. First, the raw materials, which may include iron ore, coal, and scrap metal, 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 subjected to hot-rolling, hot-drawing, or hot-extrusion processes to shape them into the desired bar or rod form. In some cases, the steel may be further twisted after the initial rolling or drawing to enhance its machinability.

Production inputs

The primary inputs required for the production of free-cutting steel bars and rods under HS code 721430 include iron ore, coal, and scrap metal, which are used as raw materials in the steelmaking process. Additionally, specialized machinery, such as furnaces, rolling mills, and extrusion presses, are essential for the various production stages. Energy sources, such as electricity and natural gas, are also crucial inputs for powering the manufacturing equipment.

Production outputs

The main output of HS code 721430 is free-cutting steel bars and rods, which are widely used in a variety of industries. These products are often consumed by manufacturers of 731500 Screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter-pins, washers and similar articles, of iron or steel, 842139 Machinery and apparatus for filtering or purifying gases, and 848180 Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves.
