Import Caustic Soda — Buy in Bulk from Supplier in China

Caustic soda from Shanghai Tianli Company is sodium hydroxide in solid form, delivered with a maximum moisture content of 0.25 percent, ensuring stability for industrial use. The product meets strict impurity limits, including sodium chloride at 0.05 percent maximum, sodium carbonate at 0.5 percent maximum, and iron oxide at 0.005 percent maximum. These thresholds make it suitable for processes where trace contaminants can affect outcomes, such as in chemical synthesis or water treatment.

The material is a white, deliquescent solid typically supplied as flakes or pearls, with a standard NaOH assay of 98 to 99 percent for industrial grades. It is fully soluble in water, producing an exothermic reaction that elevates temperature, a property exploited in soap making and pulp digestion. Industry standard classifications for caustic soda often reference ASTM E300 or GB 209, which define purity, heavy metals and alkalinity ranges for common applications.

Industrial buyers use this caustic soda in chemical manufacturing, petroleum refining, and textile processing, where its strong alkaline properties drive reactions like esterification and saponification. It is also employed in water treatment plants to adjust pH and neutralise acidic effluents. For bulk orders, confirm packaging options, as standard delivery uses 25 kg polyethylene bags with inner liners to prevent moisture absorption during transit.

Shanghai Tianli Company operates from Room 326, No. 27, 2185 Nong North Zhong Sh Road in Shanghai, China, positioning it within a major industrial and logistics hub. The supplier is classified as an imported tier entity with a harbor trust tier, indicating a baseline level of verification for international trade but no recorded response activity on the platform to date.

The company lists caustic soda as a core product, providing the chemical for industrial applications without additional details on production capacity, certifications beyond those implied by the product specs, or client references. Buyers should treat the profile as a starting point and verify all operational claims, such as factory audits or quality management systems, directly with the supplier before proceeding with orders.
