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 market is expected to grow steadily in the coming years, driven by increased construction activities and urbanization, particularly in emerging markets.

The production of hydraulic cements under HS code 252390 typically involves the grinding and blending of various raw materials, including limestone, clay, and other mineral additives. The raw materials are first crushed, then heated in a kiln to high temperatures, causing a chemical reaction that produces clinker. The clinker is then ground into a fine powder, which is the final cement product. Depending on the specific type of cement, additional materials may be added to the clinker to modify the cement's properties, such as setting time, strength, and durability.

The main inputs required for the production of hydraulic cements under HS code 252390 include limestone, clay, gypsum, and other mineral additives. Specialized machinery, such as crushers, kilns, and grinding mills, are also essential for the manufacturing process. Energy, in the form of electricity or fuel, is another significant input, as the cement production process requires high temperatures to produce the clinker.

The primary output of HS code 252390 is hydraulic cement, which is used in a wide range of construction applications. These cements are commonly used in the production of 332310 Concrete, 332320 Mortar, and 332330 Grout, which are all classified under different HS codes. The cement industry's outputs are essential for the development of infrastructure, buildings, and other construction projects, making it a crucial sector for economic growth and development.
