Lumps

Natural barium sulphate (barytes) in lump form

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2511 10 10 (natural barium sulphate — barytes — in lumps) 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. Barytes in other physical forms — powder or ground grades used in drilling fluids, paints, or rubber — may be separately classified within Chapter 25 or assessed differently under end-use notifications.

No partner government agency notification covers this tariff line.

A word of counsel

The principal importer risk at this tariff line is misclassification: barytes presented in lump form but subsequently ground or processed may be re-assessed by customs against a more specific tariff line, triggering retrospective compliance and detention pending resolution. Natural barium carbonate (witherite), classified separately within heading 2511, carries its own classification logic and should not be conflated with barytes. Verify the physical form — lumps versus powder — and the BaSO₄ purity specification against the customs tariff before the goods are shipped.
