Zinc borate
Zinc borate (3.5 H₂O) is an inorganic fire‑retardant compound supplied by China Economic International Tendering Co., Ltd. in Beijing, China. The product is presented as a technical‑grade powder with a typical purity of at least 95 % and is identified by the formula Zn₃(BO₃)₂·3.5H₂O. It is classified under HS code 2825.90 and is commonly packaged in bulk bags or fibre drums for bulk shipment. The supplier’s address on No.1 Binhe Road, Dongcheng District confirms a central location within the capital.
In the plastics and coatings sectors, zinc borate acts as a synergistic flame‑retardant and smoke suppressant, while in ceramics it serves as a flux to lower melting temperatures. Its thermal stability allows performance up to approximately 800 °C, and typical particle sizes range from 5 to 10 µm to ensure uniform dispersion. The compound is regarded as a standard additive for improving fire safety without compromising mechanical properties.
Manufacturers of polymer films, construction materials and treated wood often purchase zinc borate to meet fire‑safety regulations. The listing indicates bulk availability with flexible packaging, but does not disclose specific MOQ or lead‑time details, so buyers should request those figures directly. Hazard and safety documentation, including the SDS, should be obtained before shipment to satisfy international transport requirements.

Sourcing Zinc borate from China Economic International Tendering Co., Ltd. - China Import Guide
Prior to confirming a purchase, ask the supplier for a current Certificate of Analysis that demonstrates the ≥95 % purity of the zinc borate batch. Request copies of the company’s business licence and harbour‑level verification to validate its legal standing. Obtain the full Safety Data Sheet and any REACH or GHS compliance statements, as these are not included in the public listing.
Discuss shipping arrangements by agreeing on an appropriate Incoterm, commonly FOB from the port of Tianjin or Shanghai, and request an estimated lead time based on the supplier’s production schedule. Because the supplier’s response rate is low, it is advisable to secure a written commitment on delivery dates. Payment terms such as a confirmed L/C at sight are standard for bulk chemical transactions and should be stipulated in the contract.
Organise a pre‑shipment inspection to verify the powder’s particle size distribution, moisture content and packaging integrity against the supplied specifications. Engage an accredited laboratory to perform independent assay verification if required by your quality system. Keep the SDS, Certificate of Analysis, HS code declaration and any customs paperwork on file to streamline clearance and to provide traceability throughout the supply chain.
