Carbonates; n.e.c. in heading no. 2836 and other than lithium or strontium

HS v2017 Code: 283699

About carbonates; n.e.c. in heading no. 2836 and other than lithium or strontium

HS code 283699 covers a diverse range of carbonates that are not classified elsewhere under heading 2836, excluding lithium and strontium carbonates. These carbonates play a crucial role in various industries, from chemical manufacturing to construction materials. They are widely used as raw materials, fillers, and intermediates, contributing to the broader economy through their versatile applications.

Production process

The production of carbonates under HS code 283699 typically involves chemical reactions between carbon dioxide and various metal oxides or hydroxides. Common methods include the precipitation of carbonates from aqueous solutions, the thermal decomposition of metal bicarbonates, and the direct reaction of carbon dioxide with metal oxides or hydroxides. The specific production techniques may vary depending on the type of carbonate being manufactured.

Production inputs

The main inputs required for the production of carbonates under HS code 283699 include carbon dioxide, various metal compounds (such as oxides, hydroxides, or salts), and energy sources for the chemical reactions. Depending on the specific carbonate, additional raw materials like acids, bases, or other chemicals may be necessary. Specialized equipment, such as reactors, filtration systems, and drying units, are also essential for the manufacturing process.

Production outputs

The carbonates produced under HS code 283699 have a wide range of applications. They are used as fillers, absorbents, and neutralizing agents in industries like 282490 Other inorganic chemicals, 252320 Quicklime, slaked lime and hydraulic lime, and 252100 Limestone flux; limestone and other calcareous stone, of a kind used for the manufacture of lime or cement. These carbonates may also be further processed or combined with other materials to create more specialized products, such as 284190 Salts of oxometallic or peroxometallic acids, 284700 Peroxides, phosphates, polyphosphates, and carbonates, and 252310 Cement clinkers.
