Metal-rolling mills; tube mills

hs code 845510 covers metal-rolling mills and tube mills, which are essential equipment used in various manufacturing industries. These machines play a crucial role in shaping and processing metal materials, enabling the production of a wide range of products, from construction materials to consumer goods. The metal-rolling and tube-milling industry is a significant contributor to the global economy, supporting industries such as automotive, construction, and machinery manufacturing.

Metal-rolling mills and tube mills utilize a combination of mechanical force and heat to shape and form metal materials. The process typically involves feeding metal stock, such as sheets, bars, or tubes, into the machine, where it is subjected to high-pressure rollers or dies. These rollers or dies apply controlled pressure and heat to the metal, causing it to deform and take on the desired shape. The specific techniques used can vary depending on the type of metal, the desired final product, and the level of precision required.

The metal-rolling and tube-milling industry relies on a variety of raw materials, including 720810 hot-rolled iron or non-alloy steel products, 720920 cold-rolled iron or non-alloy steel products, and 722300 Bars and rods, hot-rolled, in irregularly wound coils, of other alloy steel. Additionally, these industries require specialized machinery, such as 845510 Metal-rolling mills; tube mills, as well as energy sources, such as electricity and natural gas, to power the production process.

The primary outputs of the metal-rolling and tube-milling industry are a wide range of metal products, including sheets, plates, bars, and tubes. These outputs are then consumed by various downstream industries, such as 730890 Structures and parts of structures, of iron or steel, n.e.s., 732111 Cooking appliances and plate warmers for domestic use, non-electric, and 870120 Road tractors for semi-trailers. The versatility of these metal products makes them essential for the construction, automotive, and machinery manufacturing sectors.
