Prices for magnesium oxide (MgO) are not fixed and vary a lot by grade, form, quantity, and delivery location. There isn’t a single “price per tonne” you can rely on without specifying the grade and terms.
Rough ballpark (industrial grades, FOB):
- Dead-burned / refractory-grade MgO: roughly in the hundreds to around 1,000+ USD per tonne, depending on purity, particle size, and form (powder vs granules).
- Light-burned MgO (LBM) used for some chemical applications: typically somewhat lower, but still in the hundreds to near 1,000 USD per tonne, depending on grade.
Pharmaceutical/food-grade MgO or other specialty grades:
- These can command higher prices per tonne due to purity, GMP packaging requirements, and regulatory compliance.
To give you a precise current price, I need a few details:
- Grade and form: dead-burned magnesia (DBM), light-burned magnesia (LBM), fused magnesia, or pharmaceutical/food grade?
- Purity and particle size (e.g., 90%, 95%, 99%+; powder vs granules).
- Quantity (tons) and packaging (bulk, 25 kg bags, etc.).
- Delivery location and terms (FOB port, CIF, DAP, etc.).
- Any specific standards or certifications required (ISO, GMP, etc.).
If you share those, I can help you draft a supplier inquiry and outline likely price ranges for your exact case, or guide you to sources to get current quotes.
