Caustic Calcined Magnesia Powder
Caustic calcined magnesia is magnesium oxide produced by low-temperature calcination of magnesite, resulting in a reactive powder used in chemical and fertilizer industries. It falls under HTS 2519.90.50.00 as 'other magnesium oxide, whether or not pure,' distinct from fused or dead-burned varieties due to its calcination process and reactivity.
