Cement clinkers (whether or not coloured)

HS v2017 Code: 252310

About cement clinkers (whether or not coloured)

HS code 252310 covers cement clinkers, which are the primary ingredient in the production of cement. Cement is a crucial material in the construction industry, used in the production of concrete, mortar, and other building materials. The global cement industry is a significant contributor to the economy, with cement clinkers being a key input for a wide range of construction projects, from residential buildings to large-scale infrastructure developments.

Production process

The production of cement clinkers involves the heating and calcination of a mixture of limestone, clay, and other raw materials in a kiln. This process, known as the 'dry process', transforms the raw materials into a hard, nodular substance called cement clinker. The clinker is then ground into a fine powder, which is then mixed with gypsum and other additives to produce the final cement product.

Production inputs

The main inputs required for the production of cement clinkers include limestone, clay, and other raw materials such as sand, iron ore, and alumina. Additionally, the cement production process requires significant energy inputs, typically in the form of coal or natural gas, to power the high-temperature kilns used in the calcination process. Specialized machinery, such as crushers, grinders, and kilns, are also essential for the efficient production of cement clinkers.

Production outputs

The primary output of HS code 252310 is cement clinkers, which are then used as the main ingredient in the production of various types of cement, including 252321 Portland cement, 252329 Other Portland cement, and 252390 Other hydraulic cements. These cement products are then consumed by the construction industry, where they are used in the production of concrete, mortar, and other building materials.
