Leucite; nepheline and nepheline syenite

HS code 252930 covers a group of rare aluminosilicate minerals, including leucite, nepheline, and nepheline syenite. These minerals are primarily used in the production of glass, ceramics, and other specialized industrial applications. As essential raw materials for various manufacturing industries, the trade and utilization of these minerals play a crucial role in the global economy.

Leucite, nepheline, and nepheline syenite are typically extracted from natural deposits through mining operations. The extracted minerals undergo various processing steps, such as crushing, screening, and beneficiation, to remove impurities and achieve the desired purity and particle size distribution. In some cases, the minerals may also be subjected to further chemical or thermal treatments to enhance their properties for specific applications.

The main inputs required for the production of leucite, nepheline, and nepheline syenite include the natural mineral deposits, mining and processing equipment, and energy sources for powering the extraction and processing operations. Additionally, the industry may rely on transportation infrastructure and logistics services to move the raw materials and processed products to their respective markets.

The primary outputs of HS code 252930 are the processed leucite, nepheline, and nepheline syenite minerals. These materials are widely used in the manufacturing of 701000 Glass and glassware, 690100 Ceramic products, and other specialized industrial applications. The outputs of this industry may also be consumed by 252100 Limestone and other calcareous stone, of a kind used for the manufacture of lime or cement and 252200 Quicklime, slaked lime and hydraulic lime industries.
