Grey Dolomite Powder supplied by Sarah Lee is a calcium‑magnesium carbonate mineral with a grey appearance. The chemical composition contains 29‑33 % CaO and 19‑22 % MgO, providing a high hardness of 3.5‑4 on the Mohs scale. The product is milled to 150 mesh and is packaged in 25 kg, 50 kg, 1 000 kg or 1 250 kg bags. Production capacity reaches 3 000 tons per month.
Dolomite of this grade typically exhibits a bulk density of around 1.5 t/m³ and a moisture content below 0.5 %. It is commonly used as a flux in steelmaking, a stabiliser in glass and ceramic manufacture, and as a filler in construction composites. The mineral meets standard specifications for industrial dolomite, often referenced against ISO 9001 quality management practices. Its fine particle size ensures uniform distribution in melt processes and improves refractory performance.
Major buyers include steel mills, glass producers and construction material manufacturers who require consistent chemistry. Shipments are loaded into 20‑foot containers with a capacity of 25‑28 metric tons and dispatched from Haiphong port, Vietnam. Importers should verify particle size distribution, chemical analysis certificates and any required customs documentation prior to purchase.

Importers should first obtain a representative sample of the dolomite powder and request a full chemical analysis report confirming CaO and MgO levels, as well as bulk density and moisture content. Ensuring the particle size distribution matches the 150 mesh specification will prevent processing issues downstream.
Clarify logistics early: decide whether the shipment will be FOB or CIF from Haiphong, verify the expected lead time for container loading and agree on payment milestones such as a 30 % deposit with the balance payable against shipping documents. The listed loading capacity of 25‑28 metric tons per 20‑foot container should be confirmed against the chosen bag size and pallet arrangement.
Arrange a third‑party inspection at the loading port and request a certificate of origin, a material test report and, if required, an ISO 9001 compliance statement. Retaining these documents will aid customs clearance and give confidence that the dolomite powder meets the technical requirements of the intended industrial application.
