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 plays a crucial role in the global manufacturing and construction sectors, providing essential materials for a wide range of applications, from infrastructure development to industrial equipment and consumer goods.

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 by combining iron, chromium, and other alloying elements in a furnace. The molten steel is then cast into slabs or billets, which are subsequently rolled and flattened using large rolling mills to achieve the desired thickness and width. The hot-rolling process is essential to impart the necessary strength and surface finish to the final product.

Production inputs

The main inputs required for the production of HS code 721921 products include high-quality stainless steel scrap or raw materials, such as iron ore, chromium, nickel, and other alloying elements. Specialized rolling mills, furnaces, and other heavy machinery are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are needed to power the production facilities.

Production outputs

The primary output of HS code 721921 is stainless steel flat-rolled products, which are widely used in various industries. These materials are often consumed by manufacturers of 730890 Structures and parts of structures, of iron or steel, n.e.s., 842139 Filtering or purifying machinery and apparatus for gases, n.e.s., and 848180 Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like, including pressure-reducing valves and thermostatically controlled valves, among others. The versatility and durability of these stainless steel products make them essential for a wide range of applications, from construction and infrastructure to industrial equipment and consumer goods.
