HS v2022 Code: 252100
About limestone flux; limestone and other calcareous stone, of a kind used for the manufacture of lime or cement
HS code 252100 covers a crucial group of materials used in the production of lime and cement, two essential components in the construction and manufacturing industries. Limestone and other calcareous stones classified under this code are mined and processed to serve as flux, a substance that aids in the smelting and refining of metals, as well as a key ingredient in the manufacture of cement and lime. The importance of this industry cannot be overstated, as it underpins the development of infrastructure, buildings, and a wide range of industrial products across the global economy.
Production process
The production of limestone flux and other calcareous stones for the manufacture of lime and cement typically involves mining, crushing, and processing the raw materials. Limestone and other calcareous rocks are extracted from quarries or mines, then crushed and screened to the desired particle size. Depending on the intended use, the processed material may undergo further treatment, such as calcination (heating to high temperatures) to produce lime, or grinding and blending to create cement feedstock.
Production inputs
The main inputs required for the production of limestone flux and other calcareous stones include the raw materials themselves, such as 251100 Limestone, including hydraulic limestone, and other calcareous stones, of a kind used for the manufacture of lime or cement, as well as specialized mining and processing equipment, such as crushers, grinders, and kilns. Energy sources, such as electricity or fossil fuels, are also essential for powering the production facilities and processing the raw materials.
Production outputs
The primary outputs of this industry are limestone flux, lime, and cement feedstock. These materials are then consumed by a variety of other industries, including 252320 Quicklime, 252400 Hydraulic cement, and 720610 Ingots, primary forms, of iron and non-alloy steel for the production of steel. The limestone flux and other calcareous stones classified under HS code 252100 are crucial inputs in the manufacturing of a wide range of construction materials, industrial products, and metals.
