Stainless steel bars and rods, hot-rolled, in irregularly wound coils

HS v2022 Code: 7221

About stainless steel bars and rods, hot-rolled, in irregularly wound coils

HS code 7221 covers the classification of stainless steel bars and rods that are hot-rolled and produced in irregularly wound coils. This industry plays a crucial role in the global supply chain, providing essential raw materials for a wide range of industries, including construction, automotive, and manufacturing. Stainless steel's unique properties, such as corrosion resistance and high strength-to-weight ratio, make it a highly sought-after material in various applications, contributing to its importance within the broader economy.

Production process

The production of stainless steel bars and rods under HS code 7221 typically involves a multi-step process. First, stainless steel is melted in an electric arc furnace or basic oxygen furnace. The molten steel is then cast into ingots or continuously cast into billets or blooms. These semi-finished products are then subjected to hot rolling, where they are passed through a series of rollers to reduce their cross-sectional area and shape them into the desired form of bars and rods. The hot-rolling process is carried out in irregularly wound coils to optimize production efficiency and material handling.

Production inputs

The main inputs required for the production of stainless steel bars and rods under HS code 7221 include stainless steel scrap, alloying elements such as chromium and nickel, and energy sources like electricity or natural gas to power the furnaces and rolling mills. Additionally, specialized machinery, such as rolling mills, casting equipment, and material handling systems, are essential for the manufacturing process.

Production outputs

The primary output of the industry covered by HS code 7221 is stainless steel bars and rods in irregularly wound coils. These products are then consumed by various downstream industries, including 7222 Stainless steel bars and rods, not further worked than cold-formed or cold-finished, 7223 Stainless steel wire, and 7304 (Tubes, pipes and hollow profiles, seamless, of iron (other than cast iron) or steel).
