About steel, stainless; flat-rolled, width 600mm or more, hot-rolled, (not in coils), of a thickness exceeding 10mm

HS code 721921 covers the classification of stainless steel flat-rolled products that are hot-rolled, have a width of 600mm or more, and a thickness exceeding 10mm. This industry is a crucial component of the global steel supply chain, providing essential raw materials for a wide range of manufacturing and construction applications. Stainless steel's unique properties, such as corrosion resistance and durability, make it a highly sought-after material in various industries, including automotive, architecture, and infrastructure development.

Production process

The production of stainless steel flat-rolled products under HS code 721921 typically involves a multi-step process. First, stainless steel is produced through a process of melting and refining raw materials, such as chromium, nickel, and other alloying elements. The molten steel is then cast into slabs or billets, which are subsequently rolled and processed to achieve the desired thickness and width. The hot-rolling process involves passing the steel through a series of rollers, which reduces the thickness and elongates the material. Finally, the hot-rolled stainless steel is cut and prepared for further processing or distribution.

Production inputs

The main inputs required for the production of HS code 721921 stainless steel flat-rolled products include raw materials such as 720810 Steel, iron or non-alloy steel; flat-rolled, width 600mm or more, hot-rolled, not clad, plated or coated, 720918 Steel, stainless; flat-rolled, width 600mm or more, hot-rolled, in coils, and other alloying elements like chromium and nickel. Additionally, specialized machinery and equipment, such as electric arc furnaces, continuous casting machines, and rolling mills, are essential for the manufacturing process.

Production outputs

The primary output of HS code 721921 is stainless steel flat-rolled products that are hot-rolled, have a width of 600mm or more, and a thickness exceeding 10mm. These materials are often used as inputs for the production of 732111 (Stoves, ranges, grates, cookers (including those with subsidiary boilers for central heating), barbecues, braziers, gas-rings, plate warmers and similar non-electric domestic appliances, and parts thereof, of iron or steel), 732190 Parts of stoves, ranges, grates, cookers and similar appliances of iron or steel, and 732611 Articles of iron or steel, forged or stamped, but not further worked; grinding balls and similar articles for mills.
