Portland cement, aluminous cement (ciment fondu), slag cement, supersulphate cement and similar hydraulic cements, whether or not coloured or in the form of clinkers

HS v2017 Code: 2523

About portland cement, aluminous cement (ciment fondu), slag cement, supersulphate cement and similar hydraulic cements, whether or not coloured or in the form of clinkers

HS code 2523 covers a range of hydraulic cements, including the widely used Portland cement, which are essential materials in the construction industry. These cements are powdery substances that harden when mixed with water, forming a durable binding agent for concrete, mortar, and other building materials. The production and trade of these cements play a crucial role in the global infrastructure and construction sectors, supporting economic development and growth worldwide.

Production process

The production of HS code 2523 cements typically involves the following key steps: quarrying and crushing of raw materials, such as limestone, clay, and gypsum; grinding and blending the raw materials to achieve the desired chemical composition; heating the mixture in a kiln to produce clinker; and finally, grinding the clinker with other additives to produce the final cement product. The specific techniques and equipment used may vary depending on the type of cement being manufactured.

Production inputs

The main inputs required for the production of HS code 2523 cements include limestone, clay, gypsum, and other mineral additives. Specialized equipment, such as crushers, mills, kilns, and grinding machines, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or fossil fuels, are needed to power the production facilities.

Production outputs

The primary output of HS code 2523 is various types of hydraulic cements, including 2523 Portland cement, 2523 aluminous cement, 2523 slag cement, and 2523 supersulphate cement. These cements are widely used in the construction industry, where they are combined with aggregates, such as sand and gravel, to produce concrete, mortar, and other building materials. The outputs of this industry are often consumed by 6810 Building and construction materials, 6811 Prefabricated buildings, and 6812 Structural non-refractory clay and siliceous mineral products.
