Cement; hydraulic kinds n.e.c. in heading no. 2523

HS code 252390 covers a wide range of hydraulic cements, which are essential materials in the construction industry. These cements are used to bind together various building materials, such as concrete, mortar, and grout, making them a crucial component in the infrastructure development of both developed and developing economies. The global cement industry is a significant contributor to economic growth, with the demand for cement closely tied to the pace of construction activities and urbanization worldwide.

The production of hydraulic cements under HS code 252390 typically involves the careful selection and blending of raw materials, such as limestone, clay, and other mineral additives. These raw materials are then ground, heated, and cooled to form a clinker, which is then further processed and combined with gypsum or other admixtures to create the final cement product. The specific production techniques may vary depending on the type of cement being manufactured, but the overall process aims to ensure the desired physical and chemical properties of the cement for its intended use.

The main inputs required for the production of hydraulic cements under HS code 252390 include limestone, clay, gypsum, and other mineral additives. Additionally, the industry relies on specialized machinery and equipment, such as crushers, mills, kilns, and packaging facilities, to ensure the efficient and consistent production of cement. Energy sources, such as coal or natural gas, are also essential for the high-temperature processes involved in cement manufacturing.

The primary output of the industry covered by HS code 252390 is hydraulic cement, which is then used in a wide range of construction applications. The cement produced under this code may be further classified into different types, such as 252321 Portland cement, 252329 Aluminous cement, or 252390 Other hydraulic cements, depending on their specific properties and intended uses. These cements are consumed by the construction industry, where they are used in the production of concrete, mortar, and other building materials, as well as in infrastructure projects, such as roads, bridges, and buildings.
