About 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 the production of hot-rolled iron or non-alloy steel bars and rods in irregularly wound coils. These products are widely used in various manufacturing and construction applications, making them an essential component of the global supply chain. Their versatility and high-quality properties make them indispensable for a wide range of industries, from automotive to infrastructure development.

Production process

The production of the goods classified under HS code 721391 typically involves a multi-step hot-rolling process. The raw materials, which are typically steel billets or blooms, are first heated to high temperatures in a furnace. They are then passed through a series of rolling mills, where the steel is gradually shaped and reduced in thickness to achieve the desired circular cross-section and diameter of less than 14mm. The resulting coils are then cooled, inspected, and prepared for further processing or distribution.

Production inputs

The primary inputs required for the production of goods under HS code 721391 include high-quality iron or non-alloy steel, as well as specialized rolling mill equipment and machinery. Additionally, energy sources such as natural gas or electricity are needed to power the furnaces and rolling mills. Other supporting inputs may include lubricants, coolants, and quality control equipment to ensure the final products meet industry standards.

Production outputs

The main outputs of the industry covered by HS code 721391 are hot-rolled iron or non-alloy steel bars and rods in irregularly wound coils. These products are often used as intermediate inputs in the manufacturing of a wide range of goods, including 731210 Wire, rods, tubes, pipes and fittings thereof, of iron or steel, 732591 Grinding balls and similar articles for mills, and 732599 Other cast articles of iron or steel, n.e.c.. The versatility of these steel products makes them essential for various industries, such as construction, automotive, and machinery manufacturing.
