HS Code for Nepheline

Nepheline and nepheline syenite are classified under HS code 2529.30. Chapter 25 of the Harmonized System covers salt, sulfur, earths, and stone, as well as plastering materials, lime, and cement. Heading 2529 is specifically for feldspar, leucite, nepheline, and nepheline syenite. Nepheline syenite is a holocrystalline plutonic rock that consists largely of nepheline and alkali feldspar. It is widely used in the glass and ceramics industries as a flux to lower the melting temperature of a batch, providing alumina and alkali. The classification 2529.30 is specific to these minerals. To remain in Chapter 25, the material must be in the crude state or washed, crushed, ground, or powdered, but not calcined or further processed in a way that changes its basic mineralogical structure. The presence of impurities does not generally affect the classification as long as the product remains a naturally occurring mineral. This classification follows GRI 1, as the mineral is named specifically in the subheading text.

Products Included

• Crude nepheline syenite rock
• Ground nepheline for ceramic glazes
• Pulverized nepheline syenite for glass manufacturing
• Nepheline concentrates
• Micronized nepheline syenite used as functional fillers

Common Misclassification

Nepheline is often misclassified under 2529.10, which is the code for Feldspar. While they are mineralogically related and often found together, the tariff provides a specific subheading (2529.30) for nepheline. It may also be confused with 2507.00 (Kaolin) or 2505.10 (Silica sands) due to its similar appearance and industrial applications in the ceramics industry.

FAQ

What is the HS code for Nepheline?

The HS code for nepheline and nepheline syenite is 2529.30.

Is processed nepheline still in Chapter 25?

As long as the processing is limited to crushing, grinding, or washing, it remains in 2529.30. If it is calcined or mixed with other chemicals, it may move to Chapter 38.
