Dunite-Derived Magnesium Oxide from Japan
Dunite-derived magnesium oxide is produced by calcining dunite rock (olivine), a natural mineral source, to yield magnesium oxide used in steelmaking and refractories. It is classified under tariff item 2519.90.00 as 'other' magnesium oxide, as it is not fused or dead-burned and the calcination process is within Chapter 25 Note 1 limits.
