Natural calcium phosphate
Unground natural calcium phosphate, unprocessed mineral form
HSN 2510 10 10 (Natural calcium phosphate, unground) 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. Ground or processed calcium phosphate, and phosphate-derived fertiliser inputs classified under Chapter 31, may attract distinct compliance at their respective tariff lines.
The absence of compliance at this tariff line applies specifically to unground natural calcium phosphate; the ground form under the same heading and phosphatic materials repurposed as fertiliser inputs under Chapter 31 each carry their own regulatory treatment. Re-classification on customs examination — for instance, where the material is determined to be ground, or to be intended for agricultural use — triggers retrospective compliance and may result in detention pending the relevant clearance. Verify the product's physical form, particle size, and declared end-use before relying on the absence of compliance at this tariff line.
