Natural calcium phosphates

Ground natural calcium phosphates

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2510 20 10 (ground natural calcium phosphates) 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 calcium phosphates intended for use as a fertiliser or fertiliser input may fall under Chapter 31, which carries its own compliance regime.

No partner government agency notification covers this tariff line.

A word of counsel

The absence of compliance at this tariff line does not extend to all calcium phosphate products: unground natural calcium phosphates are classified separately within Chapter 25, and calcium phosphate used as a fertiliser constituent may attract Chapter 31 requirements. Re-classification on customs examination — based on particle size, processing state, or declared end-use — triggers retrospective compliance, including detention pending the relevant clearance. Verify the precise specification and intended use against the customs tariff before relying on the absence of compliance here.

Unground material is classified separately within Chapter 25, and calcium phosphate marketed or used as a fertiliser input may fall under Chapter 31, each potentially attracting distinct compliance obligations.
