Raw mineral and basic plaster together

HSN 2520 covers gypsum and anhydrite (the raw minerals) as well as plasters made from calcined gypsum or calcium sulphate, coloured or not, with small quantities of accelerators/retarders permitted. It's a broader heading than "raw gypsum" alone — basic construction plaster made from it shares the same code, as long as it doesn't cross into a more specialised, separately-classified plaster product.
