Ground natural calcium phosphates and phosphatic chalk, other
HSN 2510 20 90 (ground natural calcium phosphates, aluminium calcium phosphates, and phosphatic chalk — other than standard grades) 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 phosphates intended for use as fertilisers or fertiliser inputs may fall under Chapter 31, where separate compliance regimes apply.
The absence of compliance at this tariff line does not extend to ground phosphate products that are characterised as fertilisers or fertiliser intermediates at the time of import — such products may be re-classified under Chapter 31, attracting distinct regulatory requirements. Customs re-classification on examination triggers retrospective compliance obligations, including potential detention and duty recovery. Confirm that the product specification — grade, particle size, intended end-use — supports classification under Chapter 25 before relying on the absence of compliance here.
