Carbonates; calcium carbonate

HS v2022 Code: 283650

About carbonates; calcium carbonate

HS code 283650 covers the classification of calcium carbonate, a widely used mineral compound that plays a crucial role in various industries. As a naturally occurring substance, calcium carbonate is extracted and processed for use in a diverse range of applications, from construction materials to pharmaceuticals and beyond. Its importance in the global economy stems from its versatility and the high demand for its unique properties across multiple sectors.

Production process

The production of calcium carbonate typically involves the extraction of limestone, dolomite, or other calcium-rich mineral deposits from quarries or mines. These raw materials are then crushed, ground, and purified through various chemical and physical processes to obtain the desired form of calcium carbonate, such as ground calcium carbonate (GCC) or precipitated calcium carbonate (PCC). The specific production techniques may vary depending on the intended use and the required purity level of the final product.

Production inputs

The main inputs required for the production of calcium carbonate include the raw mineral deposits, such as limestone or dolomite, as well as energy sources (e.g., electricity, fuel) for powering the extraction and processing equipment. Depending on the desired product characteristics, additional chemicals or processing aids may be used to enhance the purity, particle size, or other properties of the calcium carbonate.

Production outputs

The primary output of HS code 283650 is calcium carbonate, which is widely used in a variety of industries. Some of the key applications include 252100 Limestone flux; limestone and other calcareous stone, of a kind used for the manufacture of lime or cement, 252310 Cement clinkers, 252321 Portland cement, white, whether or not artificially colored, 252329 Portland cement, other than white cement, whether or not artificially colored, 330499 (Beauty or make-up preparations and preparations for the care of the skin (other than medicaments), including sunscreen or sun tan preparations; manicure or pedicure preparations), and 381700 Mixed alkylbenzenes and mixed alkylnaphthalenes, other than those of heading 27.07 or 29.02.
