Sodium Thiosulfate is an inorganic salt with the formula Na2S2O3 and CAS number 7772‑98‑7, offered in granular or crystalline form. The supplier provides the material in bulk, suitable for industrial applications, and it is commonly packaged in sealed 25 kg bags. It appears as a white crystalline powder and dissolves readily in water, forming a clear solution. The product meets typical industrial‑grade purity levels above 99 %.
In the chemical industry, a standard specification for sodium thiosulfate includes moisture content below 0.5 % and a pH of around 7 when a saturated solution is prepared. Typical handling requires storage in a dry, well‑ventilated area to prevent caking. The material complies with general safety standards for inorganic salts and is often shipped under HS code 2835.99, a typical classification for other inorganic chemicals. Suppliers usually advise using airtight containers to maintain stability during transport.
Users such as water‑treatment facilities, photographic labs and gold‑mining operations rely on sodium thiosulfate for dechlorination, fixing, and cyanide neutralisation respectively. Buyers should confirm minimum order quantities, packaging options and whether the shipment will be under FOB or CIF terms. Trade discussions should also cover payment methods and any required certificates before finalising the purchase.

Importers should first confirm the full legal name and address of Tianjin Manda Chemicals, as well as the harbour trust tier shown on the platform. Request a recent Certificate of Analysis that verifies the Na2S2O3 content and the stated purity above 99 %. Obtaining the safety data sheet and confirming the packaging details will reduce the risk of receiving non‑conforming material.
Discuss logistics by agreeing on the loading port in Tianjin or nearby Qingdao and selecting the appropriate Incoterm, such as FOB Tianjin or CIF Shanghai. Ask the supplier for an estimated production lead time, which can vary with order size and current demand. Clarify payment terms, for example T/T in advance or a documentary letter of credit, before the shipment is arranged.
Arrange a pre‑shipment inspection to verify that the bulk bags meet the described moisture content and that the product is free from contamination. Request any available quality management certificates, such as ISO 9001, and ensure the shipment includes a detailed packing list, commercial invoice and a certificate of origin. These documents are essential for customs clearance and for meeting downstream regulatory standards.
