Slag, dross; (other than granulated slag), scalings and other waste from the manufacture of iron or steel

HS code 261900 covers a range of waste materials generated during the production of iron and steel. These byproducts, including slag, dross, and scalings, are an integral part of the steel manufacturing process and play a crucial role in the broader metal industry. Understanding the characteristics and applications of these materials is essential for efficient resource utilization and sustainable industrial practices.

The production of slag, dross, and other steel manufacturing waste involves the separation of impurities and unwanted materials from the molten steel. This process typically occurs in the furnace or during the casting stage, where the lighter impurities rise to the surface and are skimmed off. The resulting slag and dross are then further processed, often through crushing, screening, and separation techniques, to produce various grades and sizes of these byproducts.

The primary inputs for the production of HS code 261900 materials are the raw materials used in steel manufacturing, such as iron ore, coal, and limestone. Additionally, the production process requires specialized equipment, including furnaces, casting molds, and material handling systems. The efficient management of these inputs is crucial for maximizing the yield and quality of the resulting slag, dross, and other waste products.

The outputs of HS code 261900 include a range of materials that find applications in various industries. Slag, for instance, can be used as a construction aggregate in 251710 Crushed or broken stone or as a raw material for the production of 252100 Limestone flux; limestone and other calcareous stone, of a kind used for the manufacture of lime or cement. Dross and other steel manufacturing waste may be further processed and utilized in the production of 720230 Ferro-alloys, or as a source of valuable metals through recycling and recovery processes.
