Natural aluminium calcium phosphate
Unground natural aluminium calcium phosphate
HSN 2510 10 20 (Natural aluminium 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 phosphate materials, and natural calcium phosphates applied as fertiliser inputs under Chapter 31, may fall under sibling tariff lines that carry distinct compliance obligations.
The absence of compliance at this tariff line does not extend to all phosphate-bearing minerals: ground natural calcium phosphates under heading 2510 and phosphatic materials re-classified as fertiliser inputs under Chapter 31 each carry their own regulatory treatment. Customs re-classification — triggered by particle size, processing state, or declared end-use — can convert a no-compliance import into one requiring retrospective clearance, with detention as the operative consequence. Verify the product's grinding status and intended use against the customs tariff before relying on the absence of compliance at this line.
