HS v2022 Code: 252321

About cement; portland, white, whether or not artificially coloured

HS code 252321 covers the classification of white portland cement, a specialized type of construction material that is widely used in various industries. Portland cement is a fundamental component of concrete, which is essential for the development of infrastructure, buildings, and other critical structures. The production and trade of white portland cement play a significant role in the global construction industry, contributing to economic growth and development across multiple sectors.

Production process

The production of white portland cement involves a series of carefully controlled processes. The raw materials, which typically include limestone, clay, and other mineral additives, are first crushed and ground into a fine powder. This powder is then heated in a kiln at high temperatures, undergoing a process called calcination. During this stage, the raw materials undergo chemical reactions, forming clinker. The clinker is then ground into a fine powder, which is the final product of white portland cement.

Production inputs

The main inputs required for the production of white portland cement include limestone, clay, and other mineral additives. Additionally, the manufacturing process requires specialized equipment such as crushers, mills, kilns, and grinding machines. Energy sources, such as electricity or natural gas, are also essential for powering the production facilities.

Production outputs

The primary output of HS code 252321 is white portland cement, which is a versatile construction material used in a wide range of applications. This cement is often used in the production of 332410 concrete products, 236 construction of buildings, and 237 civil engineering. White portland cement may also be used in the manufacture of 239 other non-metallic mineral products, such as decorative tiles or specialty mortars.
