Products classified under HTS 2529.30.00.10
Ground Nepheline Syenite Powder
Finely ground nepheline syenite powder derived from igneous rock deposits, primarily composed of nepheline, albite, and microcline feldspar. Classified under HTS 2529.30.0010 as nepheline syenite, used as a functional filler in paints, coatings, and plastics for improving opacity and durability.
Nepheline Syenite Ceramic Filler
Coarse-ground nepheline syenite specifically graded for ceramic tile and sanitaryware production, providing fluxing properties and whiteness. Falls under HTS 2529.30.0010 as unprocessed nepheline syenite, distinct from agglomerated forms.
K1-K Feldspar Nepheline Syenite
Premium K-feldspar rich nepheline syenite from Canadian deposits, ground to 325 mesh for glass manufacturing. HTS 2529.30.0010 covers this natural leucite-nepheline rock as specified in the hierarchy.
Unmilled Nepheline Syenite Lumps
Natural nepheline syenite in lump form (2-6 inch), crushed but not finely ground, suitable for primary grinding at destination facilities. Classified as HTS 2529.30.0010 per chapter notes excluding only advanced processing.
Nepheline Syenite for Paint Extender
Micronized nepheline syenite optimized as titanium dioxide extender in architectural paints, offering superior dispersibility. HTS 2529.30.0010 applies to this ground natural mineral per statistical definitions.
AF Sodalite Nepheline Syenite
AF-grade nepheline syenite containing sodalite inclusions, used in low-expansion glass-ceramics. Natural mineral product under HTS 2529.30.0010, distinguished by inclusion analysis.
Nepheline Syenite Glass Grade 200 Mesh
