Iron or non-alloy steel; bars and rods, hot-rolled, in irregularly wound coils, n.e.c. in heading no. 7213, of circular cross-section measuring less than 14mm in diameter

HS code 721391 covers a crucial segment of the steel industry, encompassing iron or non-alloy steel bars and rods that are hot-rolled and irregularly wound into coils. These products are widely used in various manufacturing and construction applications, making them an integral part of the global economy. Their versatility and importance in supporting industrial development cannot be overstated.

The production of goods under HS code 721391 typically involves a multi-step hot-rolling process. Raw steel billets or ingots are first heated to high temperatures, then passed through a series of rolling mills to gradually reduce the cross-sectional area and shape the material into the desired bar or rod form. The hot-rolling process allows for efficient shaping and strengthening of the steel, while the irregular coiling enables compact storage and transportation of the finished products.

The primary inputs for the production of goods under HS code 721391 include iron or non-alloy steel raw materials, such as 720410 Ferrous waste and scrap; remelting scrap ingots, of iron or steel, 720711 Iron and non-alloy steel; semi-finished products, containing by weight less than 0.25% of carbon, and 720810 Iron or non-alloy steel; flat-rolled products, of a width of 600mm or more, hot-rolled, not clad, plated or coated. Additionally, the production process requires specialized rolling mills, furnaces, and other industrial equipment to facilitate the hot-rolling and coiling operations.

The primary outputs of HS code 721391 are iron or non-alloy steel bars and rods in irregularly wound coils, with a circular cross-section measuring less than 14mm in diameter. These products are often used as inputs for various manufacturing and construction applications, such as the production of 721420 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 or twisted after rolling, 721430 Iron or non-alloy steel; bars and rods, hot-rolled, in irregularly wound coils, n.e.c. in heading no. 7214, and 721491 Iron or non-alloy steel; bars and rods, hot-rolled, in irregularly wound coils, of circular cross-section measuring 14mm or more in diameter, among others.
