Feldspar; leucite; nepheline and nepheline syenite; fluorspar

HS v2022 Code: 2529

About feldspar; leucite; nepheline and nepheline syenite; fluorspar

HS code 2529 encompasses a group of important industrial minerals that are widely used in various manufacturing processes. Feldspar, leucite, nepheline, and nepheline syenite are essential raw materials for the glass, ceramic, and chemical industries, while fluorspar is a critical input for the production of hydrofluoric acid and aluminum. These minerals play a crucial role in the global economy, supporting the development of numerous downstream products and industries.

Production process

The production of the minerals covered under HS code 2529 typically involves mining, crushing, and processing. Feldspar, leucite, and nepheline are extracted from natural deposits, often through open-pit or underground mining techniques. The extracted materials are then crushed, graded, and sometimes further processed to meet the specific requirements of end-users. Fluorspar, on the other hand, is primarily obtained through the mining and beneficiation of fluorite ore.

Production inputs

The main inputs required for the production of HS code 2529 minerals include mining equipment, crushing and processing machinery, and energy sources such as electricity or fuel. Additionally, the extraction and processing of these minerals may require water, chemicals, and specialized labor. The availability and quality of the natural deposits are also critical factors in determining the overall production capacity and efficiency.

Production outputs

The minerals classified under HS code 2529 are used as key inputs in a wide range of industries. Feldspar, leucite, and nepheline are primarily consumed by the 6901 Ceramic products, 7001 Glass and glassware, and 2823 Titanium oxides industries. Fluorspar, on the other hand, is a crucial raw material for the production of 2811 Inorganic acids, 2813 Inorganic acids, and 7601 Unwrought aluminum products.
