Iron or non-alloy steel; bars and rods, hot-rolled, in irregularly wound coils, of free-cutting steel

HS v2017 Code: 721320

About iron or non-alloy steel; bars and rods, hot-rolled, in irregularly wound coils, of free-cutting steel

HS code 721320 covers the import and export of iron or non-alloy steel bars and rods that are hot-rolled and in irregularly wound coils. This product is known as 'free-cutting steel' and is widely used in the manufacturing industry for its excellent machinability and versatility. As a crucial raw material, the trade of 721320 items plays a significant role in the global supply chain, supporting various downstream industries such as automotive, construction, and machinery production.

Production process

The production of 721320 items involves a multi-step hot-rolling process. First, steel billets or ingots are heated to a high temperature in a furnace. The heated steel is then passed through a series of rolling mills, which gradually reduce the thickness and shape the material into the desired bar or rod form. The final step is to coil the hot-rolled steel into irregularly wound coils, which facilitates storage and transportation.

Production inputs

The main inputs required for the production of 721320 items are iron ore, coal, and scrap steel. These raw materials are smelted in a blast furnace or electric arc furnace to produce the initial steel. Specialized rolling mills, cooling equipment, and coiling machinery are also essential for the hot-rolling and coiling processes.

Production outputs

The primary output of HS code 721320 is hot-rolled, irregularly wound coils of free-cutting steel bars and rods. These products are then consumed by various downstream industries, such as 731511 Grinding balls and similar articles for mills, 732591 Table, kitchen or other household articles and parts thereof, of iron or steel, and 842199 Parts of machinery for filtering or purifying liquids or gases, among others.
