2529.10.00.00 - Feldspar 🖩

This HTS category, 2529.10.00.00, specifically classifies **feldspar**. Feldspar is a group of aluminosilicate minerals that contain varying amounts of potassium, sodium, and calcium. It is a key component in many geological rocks and is primarily valued for its fluxing properties, making it indispensable in the ceramics and glass manufacturing industries. While natural feldspar is the focus, the classification also encompasses processed forms of feldspar that retain their essential mineralogical characteristics.

This classification is distinguished from its siblings by its exclusive focus on feldspar. The sibling category "Fluorspar" (2529.20.00) covers calcium fluoride (CaF2), which has distinct chemical and physical properties and is used in applications such as smelting fluxes, chemical production, and optical components. Similarly, "Leucite; nepheline and nepheline syenite" (2529.30.00) classifies specific potassium and sodium aluminum silicates with different chemical compositions and geological origins, used in specialized ceramic and glass formulations.

As this node represents a leaf classification, there are no further subcategories. Classification under 2529.10.00.00 is determined by the material being identifiable as feldspar, based on its mineralogical composition and intended use, which predominantly aligns with its role as a raw material in industrial processes.
