Magnesium Oxide Supplier China
We supply magnesium oxide (MgO) for refractory manufacturing, agricultural fertilizer blending, animal feed supplementation, wastewater treatment and industrial processing. Available in multiple grades with 25kg bags, jumbo bags, COA, TDS and MSDS for global B2B buyers.
Magnesium Oxide (MgO) Specifications
Magnesium oxide is valued for its versatility across industries. It provides a stable source of magnesium, supports high-temperature resistance, helps neutralize acidity, and contributes to process stability. The right grade depends entirely on your application — refractory production, agricultural blending, feed formulation, wastewater treatment, or industrial manufacturing.

Magnesium Oxide Supplier Proof and RFQ Checklist
Before sending a purchase order, buyers should confirm the supplier can match the exact MgO purity, calcination level, particle size, bulk density, refractory or agriculture grade, and COA limits. This checklist helps procurement teams compare real bulk supply, not casual retail purchases.
FAQ About Magnesium Oxide
What grades of magnesium oxide do you supply?
We supply refractory grade, agricultural grade, feed grade, and industrial grade magnesium oxide. The right grade depends on your application. Share your target specification and we can match the most suitable product.
What is the typical MgO purity?
Purity varies by grade and application. Common ranges include 85%-98% MgO. Final specification is confirmed by COA before shipment.
Can you provide COA, TDS and MSDS?
Yes. COA, TDS and MSDS are available for buyer review before or after order confirmation.
What packaging options are available?
Standard packaging includes 25kg bags, 50kg bags where applicable, and 1000kg jumbo bags. Pallet packing and OEM labels can be discussed by order.
What is the MOQ for bulk magnesium oxide orders?
MOQ depends on the grade and packaging. Trial orders are often supported. Full container loads reduce freight cost per ton.
Which industries use your magnesium oxide?
Our magnesium oxide is supplied to refractory plants, agricultural fertilizer blenders, feed additive manufacturers, wastewater treatment operators, and general industrial manufacturers.

Magnesium Oxide Procurement Decision Guide
Use this section to qualify magnesium oxide supplier offers before requesting a formal quotation. The goal is to compare suppliers on the same basis: grade, specification, application fit, packing, documents, delivery terms and after-sales communication.
Grade and Specification Checks
Do not compare price only by product name. Confirm the exact grade and the limits that affect your process.
- MgO content
- activity value
- mesh size
- loss on ignition
Packing and Export Documents
Ask for packing photos, label language and palletizing details before shipment. Final loading quantity should be confirmed by product density, bag size and destination requirements.
- 25kg bags
- 50kg bags
- jumbo bags by order
- COA, SDS, packing list, invoice and other export documents by order requirement

Buyer Notes for Magnesium Oxide Orders
Define activity needs
Magnesium oxide performance can depend on activity, calcination level, particle size and application. Share whether the order is for industrial processing, fertilizer, rubber or another use.
Compare real specs
Check MgO content, loss on ignition, fineness, whiteness or activity indicators when relevant. Buyers should avoid comparing light burned powder and other grades as if they are identical.
Control dust and packing
Powder handling depends on bag strength, inner liner, pallet condition and moisture protection. Confirm packing photos and warehouse requirements before arranging bulk shipment.
