Nanjing Trust Chem Co., Ltd

Based in Nanjing, China, Nanjing Trust Chem Co., Ltd lists five active products in its catalogue. The products are Benzotriazole, Tolyltriazole, Sodium benzotriazole, Sodium tolyltriazole and Liquid benzotriazole, all classified under the corrosion inhibitor category. Each chemical is supplied in standard industrial forms such as solid powder or liquid solution, matching the typical product families for organic corrosion inhibitors. The company’s catalogue does not provide HS codes, so the products fall under the broader HS chapter 29 for organic chemicals. The supplier is recorded as an imported, harbor‑tier supplier in the trade platform.

The listed items serve as corrosion‑preventive agents in cooling‑water systems, metal surface treatment and printed‑circuit board manufacturing. Benzotriazole and its sodium salt are commonly used to protect copper and its alloys, while tolyltriazole variants are applied in aluminum and steel environments. Product specifications generally include purity levels of 98 % - 99 % for analytical or technical grade, and packaging options such as 25 kg drums or 500 L bulk containers. No additional company history, employee numbers or revenue figures are supplied in the source data.

The catalogue’s five items cover both the free‑base and sodium‑salt forms of benzotriazole and tolyltriazole. In the corrosion‑inhibitor market, these chemicals are offered in grades ranging from technical (≈95 % purity) to analytical (≥99 % purity) and are evaluated by parameters such as water solubility, pH of aqueous solution and metal‑binding efficiency. Typical industry standards require a moisture content below 0.5 % for solid grades and a clear, non‑emulsified appearance for liquid formulations. Buyers often request a Certificate of Analysis that confirms purity, heavy‑metal limits (e.g., <10 ppm lead) and water content.
