Import Dolomite-Raw Stone Or Burnt — Buy in Bulk from Supplier in Viet Nam

Hoang Diep Ltd. supplies Vietnamese dolomite in both raw stone and burnt forms from Haiphong, North Vietnam. The raw stone is delivered as powder or lump with a minimum calcium oxide content of 30 % and magnesium oxide of at least 19 %. Chemical analysis also shows low iron and silicon dioxide, which is typical for Vietnamese dolomite. The burnt variant is produced by calcination and meets a loss on ignition limit of 5 % while containing 28‑32 % MgO and 45‑55 % CaO.

Both grades are commonly used as flux in steelmaking, as a neutralising agent in water treatment, and as a filler in plastics. Typical bulk density for the stone is 2.8‑3.0 t/m³, and moisture content usually lies between 0.3 % and 1.0 %. Standard packaging options are 40 kg or 50 kg paper bags, with larger jumbo bags available for bulk shipments. The material complies with the general specifications for non‑ferrous mineral feedstock used in the region.

Importers usually arrange a full container load (minimum five FCL) or twenty‑four‑ton bulk containers, but exact MOQ should be confirmed with Hoang Diep Ltd. Trade terms such as Incoterms, payment schedule and shipping schedule need to be negotiated directly with the supplier. Prospective buyers are advised to request a recent assay report and, if required, a certificate of origin before finalising the purchase.

Hoang Diep Ltd. is located at No 10 Sec A2 Block 6B Le Hong Phong St., Ngo Quyen District, Haiphong, Viet Nam. The supplier holds a harbour‑tier verification, indicating that basic business credentials have been validated on the platform.
