Natural calcium borates and concentrates thereof (whether or not calcined)

Natural calcium borates and concentrates, raw or calcined

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2528 00 30 (natural calcium borates and concentrates thereof, whether or not calcined) 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. Boron compounds that have been chemically refined or separated from natural brine fall under different headings within Chapter 28 and may attract distinct compliance obligations.

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 chemically processed boron compounds or borates separated from natural brine, which are classified outside Chapter 25 and may carry their own regulatory requirements. Re-classification on customs examination — for instance, where a product is found to be a refined chemical rather than a natural mineral concentrate — triggers retrospective compliance, including potential detention pending the relevant authorisation. Verify the degree of processing and the H3BO3 content against the customs tariff before relying on the absence of compliance here.
