Unground natural calcium phosphates and phosphatic chalk, other
HSN 2510 10 90 (unground natural calcium phosphates, natural aluminium calcium phosphates, and phosphatic chalk — other) 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 (IEC), bill of entry, commercial invoice, packing list. Ground calcium phosphates and phosphatic materials processed for use as fertilisers may fall under Chapter 31, where separate compliance requirements apply.
The absence of compliance at this tariff line does not extend to all phosphate minerals: ground calcium phosphates (classified separately within Chapter 25) and phosphatic materials presented as fertilisers under Chapter 31 each attract their own compliance regimes. Re-classification on customs examination — for instance, where the product is found to be ground or presented in a form consistent with direct agricultural application — triggers retrospective compliance and potential detention. Verify the physical form, particle size, and declared end-use against the customs tariff before relying on the absence of compliance at this line.
