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 v2017 Code: 721310

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 steel products that are widely used in construction, manufacturing, and infrastructure development. These hot-rolled steel bars and rods, with their distinctive deformations, play a vital role in the global economy, providing essential raw materials for a diverse range of industries and applications.

Production process

The production of HS 721310 steel bars and rods involves a multi-step hot-rolling process. First, steel billets or ingots are heated to high temperatures, then passed through a series of rolling mills that gradually reduce the thickness and shape the material into the desired profile. The rolling process imparts the characteristic indentations, ribs, and grooves, which enhance the steel's mechanical properties and improve its performance in various applications.

Production inputs

The primary inputs for the production of HS 721310 steel products include iron ore, coal, and other alloying elements, such as manganese, chromium, and nickel. Specialized rolling mills, furnaces, and other metalworking equipment are also essential for the manufacturing process. Additionally, skilled labor, energy, and transportation infrastructure are important resources required to support this industry.

Production outputs

The primary outputs of HS 721310 are hot-rolled steel bars and rods, which are then used as inputs for a wide range of downstream industries. These products are commonly used in the construction of buildings, bridges, and other infrastructure, as well as in the manufacturing of machinery, vehicles, and various metal products. Other HS codes that may consume the output of HS 721310 include 730120 Steel Structures and Parts of Structures, 730840 Fittings, for Scaffolding, Shuttering, Propping or Pit-propping, and 732690 Other Articles of Iron or Steel, among others.
