Strontium sulphate (natural ore)

Strontium sulphate as natural ore (celestite)

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2530 90 91 (strontium sulphate, natural ore) 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. Processed or chemically derived strontium compounds may fall under Chapter 28, where distinct compliance obligations can apply.

No partner government agency notification covers this tariff line.

A word of counsel

The absence of compliance at this tariff line applies specifically to strontium sulphate in its natural ore form (celestite); chemically processed strontium compounds — strontium carbonate, strontium oxide, or refined strontium salts classified under Chapter 28 — sit on separate tariff lines that may carry their own requirements. Customs re-classification from the natural ore line to a processed-compound line triggers retrospective compliance and potential detention. Verify that the product's processing state and chemical specification align with the natural ore description before shipment.

Frequently asked

Does HSN 2530 90 91 require any pre-import registration?

A valid Importer-Exporter Code is required for any commercial import; no product-specific registration applies to this tariff line.

What changes if the strontium sulphate has been chemically processed rather than imported as a natural ore?

Chemically processed strontium compounds are classified under Chapter 28 rather than Chapter 25, and those tariff lines may attract distinct compliance obligations.
