About slag, granulated (slag sand); from the manufacture or iron or steel

HS code 261800 covers slag, granulated (slag sand) from the manufacture of iron or steel. This industry plays a crucial role in the broader steel and metal production sectors, as the slag generated during iron and steel manufacturing is a valuable by-product with numerous applications. Granulated slag is an important input for various industries, contributing to the overall efficiency and sustainability of the metal production supply chain.

Production process

The production of granulated slag involves the rapid cooling of molten slag, a waste material generated during the smelting of iron ore or the processing of steel. The molten slag is quenched with water, causing it to solidify into a glassy, granular material. This process, known as granulation, is designed to produce a consistent, high-quality slag product that can be easily handled and transported.

Production inputs

The primary inputs for the production of granulated slag include the molten slag generated during iron and steel manufacturing, as well as the water used for the quenching and granulation process. Additionally, specialized equipment, such as slag granulators and cooling systems, are required to efficiently convert the molten slag into the desired granular form.

Production outputs

The main output of HS code 261800 is the granulated slag itself, which finds a wide range of applications. Granulated slag is commonly used as a supplementary cementitious material in the production of 2523 Portland cement, as a substitute for 2517 natural aggregates in concrete, and as a raw material in the manufacture of 6815 non-metallic mineral products. The versatility of granulated slag makes it an important input for various construction, infrastructure, and industrial sectors.
