Tianjin Ruister International Co., Ltd

Based in Tianjin, China, Tianjin Ruister International Co., Ltd lists five active products in its catalogue. The company focuses on chemicals and allied products, specifically sodium‑based inorganic compounds and chromic acid, which are common feedstocks for textile, water‑treatment and metal‑finishing applications. The product count of five reflects a narrow but defined portfolio that aligns with standard industrial chemical segments exported from China. The catalogue includes Sodium formate, Sodium sulphdie, Caustic soda (HS 2815.11, industrial‑grade sodium hydroxide), Sodium metabisulfite (HS 2832.10, inorganic sulphite compound) and Chromic acid (HS 2801.30, chromium‑VI oxide). Each entry is identified by its HS‑code family, allowing buyers to match customs documentation and regulatory requirements for the respective material.

The listed products cover three HS‑code chapters: 2815 for caustic soda, 2832 for sodium metabisulfite and 2801 for chromic acid. In the global market, caustic soda is typically supplied at 99 % purity or higher, packed in 25 kg polyethylene drums or 1 ton bulk containers. Sodium metabisulfite is often offered with a minimum purity of 98 % and moisture content below 0.5 %, while sodium formate and sodium sulphdie are usually supplied as 99 % pure powders in 20 ft or 40 ft containers. Industry standards for these chemicals include compliance with REACH registration in the EU, MSDS documentation, and where applicable ISO 9001 quality management. Buyers frequently request assay certificates that specify % purity, heavy‑metal limits, and water content, especially for applications in food processing or pharmaceuticals.
