Potassium Sodium Tartrate, commonly called Rochelle salt, is the tetrahydrate salt KNaC4H4O6·4H2O with a minimum purity of 99 % across technical, food and pharmaceutical grades. The compound appears as a white crystalline solid and is supplied in 25 kg bags or drums for bulk trade. Supplier Wuhan Silworld Chemical Co., Ltd. highlights its use in food processing, pharmaceuticals and piezoelectric applications, and the listing references compliance with ISO and FSSAI standards.
Typical industry specifications for Rochelle salt include a bulk density of around 1.2 g cm‑3 and a solubility of approximately 12 g per 100 mL of water at 20 °C, values that help engineers design formulation processes. The material is mildly hygroscopic, so standard practice is to keep it in sealed, dry containers to maintain stability. Although the supplier does not list a specific CAS number, the compound is widely recognised under CAS 304‑59‑6, a reference useful for regulatory documentation.
Key end‑users are food manufacturers seeking leavening or stabilising agents, pharmaceutical formulators using it as an excipient, and electronics firms that exploit its piezoelectric properties. Buyers should confirm the exact packaging configuration, incoterm preferences and any required documentation before finalising a purchase, as the listing does not disclose minimum order quantities or lead‑time details.

Prior to ordering, ask the supplier for a current certificate of analysis, proof of ISO or FSSAI compliance and any additional test reports relevant to your application. Verifying the exact purity, moisture content and heavy‑metal limits will help ensure the material meets regulatory and performance requirements.
Clarify logistics early by agreeing on the incoterm (for example FOB Wuhan port or CIF Shanghai) and confirming the typical lead time for production and dispatch. Payment terms such as L/C at sight or T/T in advance should be discussed to align with your financial controls, and the supplier should outline any required advance deposits.
Arrange for a third‑party inspection if independent verification is needed, focusing on packaging integrity, moisture levels and assay accuracy. Ensure the supplier can provide a full documentation package, including a material safety data sheet, packing list and customs invoice, to facilitate smooth import clearance and quality assurance on arrival.
