Sodium Tripolyphosphate (STPP, E451, CAS 7758‑29‑4) supplied by Dinayen Enterprise Management is a food‑grade sodium polyphosphate presented as white granular or powdered material. The product meets a minimum assay of 95 % Na5P3O10 and is supplied with at least 85 % purity for food applications. Standard specifications list a white appearance, P2O5 content of 57 % min and a pH between 9.5 and 10.0. It is packed in 25 kg bags or jumbo bags suitable for bulk export.
Food‑grade STPP is widely used as a binder, stabiliser and chelating agent in processed meats, bakery mixes and seafood preservation. In the global market the compound is typically supplied with moisture below 0.7 % and a loss‑on‑drying not exceeding 0.7 %. Standard industry practice limits heavy metals such as cadmium to 1 ppm and lead to 4 ppm, matching the values shown for this batch. Typical storage conditions are cool, dry warehouses with a shelf life of 24 months when kept sealed.
The primary buyers are food manufacturers, detergent formulators and industrial cleaners who require consistent chelating performance. Dinayen notes that the product complies with international food safety standards, but exact pricing, minimum order quantity and delivery incoterms must be confirmed directly. The supplier indicates a response time of one working day for enquiries, although current response metrics are not recorded. Importers should verify the certificate of analysis and any required import licences before shipment.

Before placing an order, importers should request the supplier’s certificate of analysis and any relevant food‑safety certificates to confirm the 95 % assay and heavy‑metal limits. Verify the packaging type, batch number and storage recommendations provided in the technical data sheet. It is also prudent to ask for a recent lab report that includes moisture, pH and hexahydrate content. Confirm that the product complies with the destination country’s food additive regulations.
Dinayen does not list specific incoterms or lead‑time in the public profile, so buyers must negotiate these terms directly. Common practice for bulk chemicals is FOB Nanjing or CIF major Asian ports, with payment by T/T or LC after a satisfactory pre‑shipment sample. Clarify freight options, insurance coverage and any required export documentation such as a material safety data sheet. Align the agreed terms with your company’s procurement policy to avoid unexpected costs.
Upon arrival, conduct a visual inspection for packaging integrity and a laboratory test to confirm assay, pH and heavy‑metal limits. Engaging a third‑party inspection agency to verify the certificate of analysis can reduce risk. Retain the batch‑specific documentation, including the supplier’s safety data sheet, for regulatory filing and future reference. Establish a post‑delivery audit routine to ensure consistent quality across shipments.
