Mica powder, calcined

Calcined mica powder, ground or processed

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2525 20 50 (Mica powder, 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. Mica in other forms — splittings, waste, or unprocessed block mica — falls under sibling tariff lines within Chapter 25 that may attract distinct classification treatment.

No partner government agency notification covers this tariff line.

A word of counsel

The principal importer risk at this tariff line is misclassification: calcined mica powder is distinguished from uncalcined mica powder, mica splittings, and mica waste, each of which occupies a separate tariff line within Chapter 25. Re-classification by customs on examination triggers retrospective compliance obligations and may result in detention pending resolution. Verify the processing state — specifically whether the product has been thermally treated — and the particle size specification before filing the bill of entry.

Mica splittings and mica waste are classified under separate tariff lines within Chapter 25 and must be assessed independently for applicable compliance and duty treatment.
