Import Tips

• Mandate XRF analysis certificates showing CaO/SiO2 ratio <1.2 for EAF grade verification

• Avoid common error of declaring as 'caustic magnesia'; fused magnesia has distinct crystalline structure visible via XRD testing

• For container loads, ensure ventilation certificates as magnesia dust can be reactive with moisture
