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 specialty chemicals. They play a crucial role in various industries, contributing to the manufacturing of a wide range of products that are essential for modern life.

Leucite, nepheline, and nepheline syenite are typically mined from natural deposits and then processed through a series of steps. The raw materials are extracted, crushed, and then subjected to various purification and refinement processes to remove impurities and achieve the desired purity and composition. The refined minerals are then used as key ingredients in the production of glass, ceramics, and other specialized products.

The main inputs required for the production of leucite, nepheline, and nepheline syenite include the raw mineral deposits, which are typically found in volcanic or igneous rock formations. Additionally, the production process may involve the use of specialized mining and processing equipment, as well as energy sources, such as electricity or fuel, to power the various stages of extraction and refinement.

The primary outputs of HS code 252930 are the refined leucite, nepheline, and nepheline syenite minerals. These materials are widely used in the 701000 Glass and glassware industry, where they serve as key components in the production of specialized glass formulations. They are also utilized in the 691000 Ceramic products industry, contributing to the manufacture of high-quality ceramics and porcelain. Additionally, these minerals find applications in the production of 282500 Inorganic chemicals, particularly in the synthesis of certain specialty chemicals.
