HS Code for Leucite

Leucite is classified under HS code 2529.30. This code is located within Chapter 25, which covers salt, sulfur, earths and stone, plastering materials, lime, and cement. Heading 2529 specifically includes feldspar, leucite, nepheline, and nepheline syenite. Leucite is a rock-forming mineral consisting of potassium and aluminum tectosilicate. It is typically found in potassium-rich volcanic rocks. The classification under 2529.30 is straightforward because the mineral is explicitly named in the subheading. According to the Explanatory Notes to Chapter 25, products of this chapter are generally in the crude state or washed, crushed, ground, or powdered, but not calcined or further processed. Leucite is primarily used in the glass and ceramics industries as a flux and in the production of certain types of dental porcelain due to its thermal expansion properties. Because it is a naturally occurring mineral that has not been chemically altered or refined into a pure chemical compound, it remains in Chapter 25 rather than Chapter 28. The classification ensures that industrial minerals are tracked for environmental and mining regulatory purposes.

Products Included

• Natural leucite mineral
• Crushed leucite
• Ground or powdered leucite
• Nepheline
• Nepheline syenite

Common Misclassification

Leucite is often misclassified under 2529.10, which is the specific code for feldspar. While related, they are distinct minerals. It can also be confused with precious stones in Chapter 71 if the crystals are of gem quality, though this is rare. Additionally, if leucite is processed into a pure chemical, it might be incorrectly placed in 2839 (silicates).
