Tetrakis Phosphonium Sulfate (THPS)
Tetrakis Phosphonium Sulfate (THPS) supplied by Hangzhou Bayee Chemical Co., Ltd is a technical‑grade organophosphonium biocide with the molecular formula C8H24O12P2S. The product is provided as a liquid containing at least 75 % assay and a minimum active phosphorus content of 11 %. It is shipped in standard steel drums or IBC containers, complying with HS code 2931.39.9090 for customs classification. The supplier lists a relative density of 1.35‑1.42 g/cm³ at 25 °C.
THPS is widely used in water‑treatment, oil‑field and industrial preservation because of its broad antimicrobial spectrum. Typical industry specifications call for a viscosity of 30‑40 mPa·s at 25 °C and iron impurity below 10 ppm (typical). The solution appears clear to slightly yellowish and remains stable at temperatures down to - 35 °C (typical for this grade). While the supplier does not provide formal certification documents, the product meets standard hazardous‑material classifications, listed under UN 2922 and Hazardous Grade 8.
End users such as refinery water‑treatment plants, textile manufacturers and paper mills employ THPS to control microbial growth and as a flame‑retardant intermediate. Hangzhou Bayee offers flexible minimum order quantities and can arrange both FOB and CIF shipping, though exact terms should be confirmed with the sales team. Prospective buyers are advised to request a current certificate of analysis and safety data sheet before finalising the purchase. Confirming packaging integrity and the supplier’s ability to meet the required pH range of 2.5‑5.5 will help ensure seamless integration into process streams.

Sourcing Tetrakis Phosphonium Sulfate (THPS) from Hangzhou Bayee Chemical Co., Ltd. - China Import Guide
Before committing to a purchase, importers should ask for a current certificate of analysis confirming the 75 % assay and verify that the product is packed in steel drums or IBC totes as described. Request the latest safety data sheet and any available test reports on antimicrobial performance. Confirm the supplier’s registered address in Hangzhou and its harbor trust tier rating to gauge reliability. Direct contact with the sales department can clarify any outstanding technical questions.
Typical lead times for bulk THPS shipments from Hangzhou range from three to five weeks, depending on production scheduling and export documentation. Buyers may select FOB or CIF incoterms; FOB places loading responsibility on the supplier, while CIF includes freight and insurance to the destination port. Payment is commonly arranged via T/T against the Bill of Lading or through a confirmed Letter of Credit, both of which should be agreed upon before dispatch.
Upon receipt, importers should conduct an independent inspection to verify volume, appearance and absence of contamination. Laboratory sampling can confirm assay, viscosity and iron impurity levels against the specifications provided. Retaining the supplier’s material safety data sheet, certificate of analysis and packing list will facilitate customs clearance and ensure compliance with local hazardous‑material regulations. Documenting these checks provides a traceable record for future quality audits.
