Leucite; nepheline and nepheline syenite
Leucite, nepheline, and nepheline syenite minerals
HSN 2529 30 00 (Leucite; nepheline and nepheline syenite) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code, bill of entry, commercial invoice, packing list. Other tariff lines within Chapter 25 — notably feldspar and fluorspar, which share heading 2529 — may carry distinct compliance considerations; classification accuracy between these mineral types is the principal importer risk.
Leucite, nepheline, and nepheline syenite are aluminium silicate minerals used primarily in ceramics, glass, and the chemicals industry; the absence of compliance at this tariff line does not extend to related minerals classified elsewhere in Chapter 25. Fluorspar, which falls under a separate subheading of heading 2529, and certain processed mineral derivatives further along the value chain, attract their own compliance regimes. Verify the precise mineral composition and processing state against the customs tariff before relying on the absence of compliance, as re-classification triggers retrospective compliance and potential detention.
