Fluorspar; containing by weight 97% or less of calcium fluoride

HS code 252921 covers fluorspar, a mineral that is primarily composed of calcium fluoride. Fluorspar is an essential raw material in various industries, including steel production, aluminum smelting, and the manufacturing of hydrofluoric acid, which is a key ingredient in the production of fluorocarbons and other fluorine-based chemicals. As a result, the fluorspar industry plays a vital role in supporting the broader chemical and metallurgical sectors, contributing to the overall economic development of countries worldwide.

Fluorspar is typically extracted from natural deposits through mining operations. The raw material is then processed to remove impurities and concentrate the calcium fluoride content. This may involve crushing, screening, and flotation techniques to separate the fluorspar from other minerals. The purified fluorspar is then graded and packaged for distribution to various end-use industries.

The primary input for the fluorspar industry is the raw mineral, which is mined from natural deposits. Specialized mining equipment, such as excavators, crushers, and processing plants, are required to extract and refine the fluorspar. Additionally, the industry relies on energy sources, such as electricity or fuel, to power the mining and processing operations.

The primary output of HS code 252921 is refined fluorspar, which is then consumed by various downstream industries. These include 720260 Ferrosilicon, 281810 Anhydrous aluminium oxide, and 281810 Hydrofluoric acid, among others. The fluorspar produced under this code can be further classified into different grades based on its calcium fluoride content, purity, and other specifications, catering to the specific requirements of each end-use industry.
