Calcined

Calcined plasters of gypsum or calcium sulphate

NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 2520 20 10 (calcined plasters of gypsum or calcium sulphate) 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. Other products within Chapter 25 — including raw gypsum, anhydrite, or specially formulated plasters with significant additive content — may attract distinct classification treatment and should be verified separately.

No partner government agency notification covers this tariff line.

A word of counsel

The absence of compliance at this tariff line applies specifically to calcined plasters in their basic form; plasters that are pre-mixed, coloured, or formulated with substantial quantities of accelerators or retarders may be reclassified to a sibling line within Chapter 25 or, depending on end use, to Chapter 38 (miscellaneous chemical products). Customs re-classification on examination triggers retrospective compliance and potential detention. Confirm that the product specification — calcination state, additive percentage, and intended use — maps precisely to this tariff line before shipment.

Plasters with substantial additive content may be reclassified to a different tariff line within Chapter 25 or beyond, which could attract its own compliance requirements.
