Kieserite, epsomite (natural magnesium sulphates)

Kieserite and epsomite, natural magnesium sulphates

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2530 20 00 (kieserite and epsomite — natural magnesium sulphates) 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. Magnesium sulphate products processed beyond their natural mineral form, or classified for fertiliser use, may fall under sibling lines in Chapter 25 or Chapter 31 that carry distinct compliance.

No partner government agency notification covers this tariff line.

A word of counsel

The absence of compliance at this tariff line applies strictly to natural, unprocessed kieserite and epsomite; chemically synthesised or purified magnesium sulphate may be classified elsewhere in the tariff schedule and attract separate requirements. Re-classification by customs on examination — for instance, to a Chapter 31 fertiliser heading — triggers retrospective compliance and potential detention pending resolution. Confirm the product's mineralogical origin, processing state, and declared end-use before relying on the absence of compliance at this line.

Frequently asked

Does HSN 2530 20 00 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 magnesium sulphate is synthesised or sold as a fertiliser input?

Chemically produced or fertiliser-grade magnesium sulphate may be classified under Chapter 31, which carries its own compliance regime, and re-classification by customs triggers retrospective compliance obligations.
