Sodium metabisulfite
Tianjin Ruister International Co., Ltd., located in Tianjin, China, produces sodium metabisulphite (Na2S2O5) as a white crystalline powder. The company offers three grades - Food Grade, Industrial Grade and Photographic Grade - each with a minimum purity of 97 % for the food‑grade variant. Products are supplied in 25 kg bulk bags or larger jumbo bags, matching the bulk‑shipping formats common in the chemical trade. The material conforms to ISO and SGS quality certifications as stated.
Sodium metabisulphite is prized for its strong reducing ability, making it a standard antioxidant in food preservation and a bleaching agent in textile and leather processing. Typical industry benchmarks call for moisture content not exceeding 0.5 % and particle size below 200 mesh, both of which align with the supplier’s quality expectations. Standard bulk density lies between 0.8 and 1.0 g cm⁻³ and solubility reaches about 30 g per 100 mL of water at 20 °C, facilitating easy incorporation into manufacturing streams. These typical parameters support its use across beverage, water‑treatment and photographic applications.
Clients such as food processors, beverage manufacturers, water‑treatment plants and photographic film producers frequently source this compound in large volumes. Tianjin Ruister can provide FOB or CIF terms and accepts payment via L/C or T/T, allowing flexibility for international buyers. The supplier’s harbour‑level trust rating indicates a verified status, but buyers should still request current certification copies and confirm any specific grade requirements before confirming the purchase.

Sourcing Sodium metabisulfite from Tianjin Ruister International Co., Ltd - China Import Guide
When ordering from Tianjin Ruister, ask for the latest certificate of analysis that confirms the ≥97 % purity and the specific grade you require. Request the material safety data sheet to review handling instructions, storage temperature limits and moisture specifications. Verify the harbour‑level trust tier and, if possible, obtain recent audit or inspection reports to assess the supplier’s compliance.
Clarify the preferred Incoterms early; the supplier offers both FOB and CIF, so select the term that aligns with your freight and insurance strategy. Because the listing does not state a fixed lead time, request an estimated production and dispatch schedule for the chosen packaging size. Confirm that payment can be made by confirmed L/C or T/T, and ensure the banking details match those provided in the commercial documentation.
Plan a third‑party pre‑shipment inspection to validate purity, moisture content and packaging integrity against the certificate of analysis. Insist on receiving the full documentation package - commercial invoice, packing list, certificate of origin and the batch‑level certificate of analysis - to avoid customs delays. These steps help maintain product quality and streamline the import process.
