Barium carbonate (witherite); natural, whether or not calcined, other than barium oxide of heading no. 2816

HS code 251120 covers the classification of barium carbonate, also known as witherite, a naturally occurring mineral that is widely used in various industries. Barium carbonate is an essential raw material in the production of glass, ceramics, and certain types of electronic components. Its unique chemical properties make it a crucial ingredient in the manufacturing of a diverse range of products, contributing to its importance in the global economy.

Barium carbonate is primarily extracted from natural deposits through mining operations. The extracted ore is then crushed, milled, and processed to remove impurities, resulting in a high-purity barium carbonate product. In some cases, the natural barium carbonate may undergo calcination, a process of heating the material to a high temperature, to further refine and purify the final product.

The main inputs required for the production of barium carbonate (HS code 251120) include the natural barium carbonate ore, as well as various processing equipment and machinery used for crushing, milling, and purification. Additionally, energy sources, such as electricity or fuel, are necessary to power the production facilities and carry out the various processing steps.

The primary output of HS code 251120 is refined barium carbonate, which is then used as a raw material in a wide range of industries. Some of the key industries that consume barium carbonate include the 701000 Glass and glassware, 690000 Ceramic products, and 854000 Electrical machinery and equipment. Barium carbonate is also used in the production of certain 281600 Inorganic chemicals, such as barium oxide and barium hydroxide.
