Calm Ocean Ltd supplies silica sand produced in Quang Binh, Viet Nam. The sand meets a SiO₂ content of 99.5 % and contains low impurity levels of Fe₂O₃ (0.0116 %), TiO₂ (0.017 %) and Al₂O₃ (0.13 %). The product is marketed for glass industry production and is packed in jumbo bags of 1.3 metric tonnes each. The listing does not disclose a minimum order, and payment terms are not stated.
In the glass‑making sector, typical silica sand specifications call for particle sizes between 100 µm and 400 µm, with a density near 2.43 g/cm³ and moisture below 1 %. Calm Ocean Ltd’s sand conforms to these norms, and the low iron oxide content helps maintain optical clarity during melting. Standard practice classifies this material as glass‑grade quartz sand, which is usually free‑flowing and chemically stable.
Potential buyers include container glass manufacturers, flat‑glass producers and optical component makers that require consistent silica purity. The sand is shipped in jumbo bags suitable for containerised freight, allowing flexible handling at destination ports. Importers should confirm bag loading capacity, vessel schedule and any required export documentation before finalising the purchase.

Prior to ordering, request a recent laboratory report confirming SiO₂ purity, Fe₂O₃, TiO₂ and Al₂O₃ levels, as well as particle size distribution. Verify that the moisture content is below 1 % and that the pH matches the listed value of 8.6. Ensure the jumbo‑bag specifications meet your handling equipment and that the supplier can provide the necessary export licences for Viet Nam.
Shipping is typically arranged on a CIF or FOB basis from the nearest port in Quang Binh, with the sand loaded in 1.3‑tonne jumbo bags for containerised transport. Lead times depend on container availability and customs clearance; discuss scheduling with the supplier to avoid delays. Payment terms are not defined in the listing, so confirm whether a Letter of Credit, advance payment or open account is preferred before contract signing.
Arrange a third‑party inspection either pre‑load or at the destination port to verify compliance with the agreed specifications. Ask for a Certificate of Analysis and any mineral composition certificates to accompany the cargo. Proper documentation, including a commercial invoice, packing list and bill of lading, will facilitate smooth customs clearance in the importing country.
