Processed, other than calcined (washed or ground or screened or beneficiated)
Andalusite, kyanite and sillimanite, processed but not calcined
HSN 2508 50 22 (andalusite, kyanite and sillimanite — processed other than calcined, i.e. washed, ground, screened, or beneficiated) 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, bill of entry, commercial invoice, packing list. Calcined grades of the same minerals, and refractory products manufactured from them, may fall under separate tariff lines within Chapter 25 or Chapter 69 that carry distinct compliance.
The principal importer risk is misclassification: calcined andalusite, kyanite, or sillimanite is separately classified within Chapter 25, and refractory bricks or shapes incorporating these minerals fall under Chapter 69 — each with their own potential compliance exposure. Customs re-classification on examination triggers retrospective compliance obligations, including detention pending resolution. Confirm the precise processing state and downstream application against the customs tariff before relying on the absence of compliance at this tariff line.
