HS v2017 Code: 2511
About natural barium sulphate (barytes); natural barium carbonate, (witherite) whether or not calcined, other than barium oxide of heading no. 2816
HS code 2511 covers the classification of natural barium sulphate, also known as barytes, and natural barium carbonate, or witherite. These minerals are important industrial materials with a wide range of applications across various sectors. Barytes, in particular, is a crucial component in the oil and gas industry, while witherite finds use in the production of glass, ceramics, and other specialty chemicals.
Production process
Natural barium sulphate and barium carbonate are typically extracted from mineral deposits through mining operations. The raw materials are then processed, which may involve crushing, grinding, and in some cases, calcination (heating to high temperatures) to remove impurities and refine the final product. The specific production techniques can vary depending on the purity requirements and the intended end-use of the materials.
Production inputs
The primary inputs for the production of natural barium sulphate and barium carbonate are the mineral deposits themselves. Mining equipment, such as excavators, crushers, and grinding mills, are also essential resources. Additionally, energy sources, such as electricity or fuel, are required to power the processing and refining operations.
Production outputs
The main outputs of HS code 2511 are refined natural barium sulphate (barytes) and natural barium carbonate (witherite). These materials are widely used in various industries, including 2707 Oils and other products of the distillation of high temperature coal tar; similar products in which the weight of the aromatic constituents exceeds that of the non-aromatic constituents, 2816 Hydroxide and peroxide of magnesium; oxides, hydroxides and peroxides, of strontium or barium, and 6810 Articles of cement, of concrete or of artificial stone, whether or not reinforced.
