Iron or non-alloy steel; bars and rods, n.e.c. in chapter 72, n.e.c. in heading no. 7215

HS code 721590 covers a diverse range of iron or non-alloy steel bars and rods that are not classified elsewhere in Chapter 72 or Heading 7215. These products play a crucial role in various industries, including construction, manufacturing, and infrastructure development. They are widely used as raw materials for the production of a wide array of metal goods, making them an integral part of the global supply chain.

The production of iron or non-alloy steel bars and rods under HS code 721590 typically involves a series of processes, including melting, casting, rolling, and finishing. Steel mills use blast furnaces or electric arc furnaces to melt iron ore, scrap metal, and other raw materials, producing molten steel. The molten steel is then cast into various shapes, such as billets or blooms, which are subsequently rolled into the desired bar or rod profiles using specialized rolling mills. Finally, the bars and rods may undergo additional finishing processes, such as heat treatment, straightening, or surface treatment, to meet specific customer requirements.

The main inputs required for the production of iron or non-alloy steel bars and rods under HS code 721590 include iron ore, scrap metal, alloying elements (such as manganese, chromium, or nickel), and various types of energy sources (e.g., coal, natural gas, or electricity) to power the production facilities. Additionally, specialized machinery, such as blast furnaces, rolling mills, and finishing equipment, are essential for the manufacturing process.

The primary outputs of HS code 721590 are iron or non-alloy steel bars and rods, which are then consumed by a wide range of downstream industries. These products may be used in the production of 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, 732690 Other articles of iron or steel, and various other metal goods and components. The versatility of these bars and rods makes them an essential input for many manufacturing and construction activities.
