Plasters based on calcined gypsum or calcium sulphate, other
HSN 2520 20 90 (Other plasters — consisting of calcined gypsum or calcium sulphate, whether or not coloured, with or without small quantities of accelerators or retarders) 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. Plaster products formulated for specific end uses — such as dental or surgical plasters — may fall under sibling tariff lines or under Chapter 30, where distinct compliance requirements can apply.
The absence of compliance at this tariff line does not extend to all plaster products within Chapter 25: plasters specifically adapted for use in dentistry or surgery, and finished construction plaster products marketed under product standards, may be classified differently and attract their own obligations. Re-classification on customs examination triggers retrospective compliance, including detention pending resolution. Verify the precise formulation, intended use, and any accelerator or retarder content against the customs tariff before relying on the absence of compliance.
