Wollastonite

Wollastonite, a naturally occurring calcium silicate mineral

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2530 90 50 (Wollastonite) 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. Other mineral substances under Chapter 25 — particularly those used as ceramic raw materials, fillers, or reinforcing agents — may fall under sibling tariff lines that attract compliance obligations where the intended industrial application changes the classification.

No partner government agency notification covers this tariff line.

A word of counsel

The principal importer risk at this tariff line is misclassification: wollastonite used as a filler in plastics or paints may attract scrutiny under chapters covering prepared mineral pigments or additives, while wollastonite-based ceramic products processed beyond the raw mineral stage fall outside Chapter 25 entirely. Customs re-classification on examination can trigger retrospective duty recovery and detention pending resolution. Confirm the product's physical state, processing level, and declared end-use against the customs tariff before shipment.

Frequently asked

Does HSN 2530 90 50 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 wollastonite has been processed into a ceramic or composite product?

Processed or manufactured articles containing wollastonite as a constituent — rather than the raw mineral — are classified outside Chapter 25 and may attract compliance obligations under the applicable product-specific chapter.
