About iron or non-alloy steel; bars and rods, hot-rolled, in irregularly wound coils, containing indentations, ribs, grooves or other deformations produced during the rolling process

HS code 721310 covers a crucial category of iron and non-alloy steel products - hot-rolled bars and rods with various deformations produced during the rolling process. These products are widely used in the construction, automotive, and manufacturing industries, playing a vital role in the broader global economy. Their versatility and durability make them indispensable raw materials for a wide range of applications.

Production process

The production of HS 721310 items typically involves a multi-step hot-rolling process. First, steel billets or ingots are heated to high temperatures, then passed through a series of rolling stands to gradually reduce the cross-section and impart the desired deformations, such as indentations, ribs, or grooves. The resulting coils are then cooled, cut, and prepared for distribution to various downstream industries.

Production inputs

The main inputs required for the production of HS 721310 items include iron ore, coal, and other raw materials used in steelmaking, as well as specialized rolling mill equipment and machinery. Energy sources, such as electricity or natural gas, are also essential for the high-temperature heating and rolling processes. Additionally, skilled labor, including metallurgists, engineers, and technicians, is crucial for ensuring consistent quality and efficient production.

Production outputs

HS 721310 products are primarily consumed by the 730820 Construction materials and 870120 Motor vehicles industries, where they are used as reinforcement in concrete structures, as well as components in automotive chassis and suspension systems. The deformations on the bars and rods help improve their mechanical properties and bonding capabilities, making them essential for these applications. Other industries, such as 731100 Containers for compressed or liquefied gas and 848120 Valves for oleohydraulic or pneumatic transmissions, may also utilize HS 721310 products in their manufacturing processes.
