Import Calcined Dolomite — Buy in Bulk from Supplier in Viet Nam

Calcined dolomite from Hoangdiep Ltd is a thermally processed mineral with a minimum magnesium oxide content of 34% and calcium oxide exceeding 54%, delivered from Viet Nam. The material undergoes calcination to remove carbon dioxide, increasing its reactivity and suitability for industrial applications. Particle size distribution is consistent, enabling reliable handling in bulk production environments.

The product is a refined form of dolomite, typically composed of calcium magnesium carbonate, heated to drive off CO2 and leave a stable oxide blend. Industrial users value its high CaO and MgO levels, which are standard for fluxing in metallurgy, glass manufacturing, and as a soil conditioner in agriculture. Typical bulk density for calcined dolomite ranges between 1.5 and 1.8 g/cm³, depending on the degree of calcination and residual moisture.

Primary buyers include steel mills, glass producers, and agricultural co-operatives seeking a reactive lime alternative. Common trade terms for bulk shipments from Viet Nam involve FOB Hai Phong, with packaging in 1.5 tonne jumbo bags or bulk vessel loading. Buyers should confirm incoterms, as the supplier’s listed profile does not specify lead times or MOQ, which must be negotiated directly.

Hoangdiep Ltd is based at 13/2 Du Hang Street in Le Chan District, Hai Phong, Viet Nam, operating as an importer of industrial minerals. The company’s profile indicates a harbor-tier trust level, reflecting a verified business address but no published response rate or average response time to date. This suggests buyers should expect to initiate contact directly for trade terms.

The supplier’s listing focuses on calcined dolomite, with no additional product categories or certifications stated. There is no disclosed history, headcount, or client base, so due diligence on production capacity and quality control must be conducted by the buyer. The absence of a response rate signal means pre-order communication may require persistence to establish lead times and logistics.
