Caustic soda flake
Caustic soda flakes from Tianjin Shi Jinhong Weibang Chemical CO., Ltd. are supplied as white, solid sodium hydroxide (NaOH) with a minimum purity of 99%, conforming to GB209-2006 industry grade standards. The product is available in flake or pearl form, packaged in 25 kg woven bags with waterproof HDPE liners, with one 20-foot container holding 26 to 27 metric tons. Bulk bag options of 1 metric ton per unit are also offered, with pallets available on request to reduce container capacity to 24 tons.
Sodium hydroxide is a highly caustic metallic base, soluble in water, ethanol, and methanol, and is deliquescent, readily absorbing moisture and carbon dioxide from the air. The flakes are produced via ionic membrane or diaphragm liquid alkali processes, with rigorous laboratory testing of raw materials and controlled heating to 180°C to remove impurities. Typical industry applications include pulp and paper manufacturing, textile dyeing, soap and detergent production, water treatment, and aluminium oxide refinement.
This commodity is a high-volume chemical traded globally, with demand driven by manufacturing sectors requiring strong alkaline solutions. Buyers typically source it in bulk for industrial processes, with logistics adapted to its corrosive nature. Tianjin’s proximity to Xingang port ensures efficient export, with common trade terms including CIF or FOB basis per metric ton. The product’s versatility makes it essential for industries ranging from soft drink processing to petroleum refining.

Sourcing Caustic soda flake from Tianjin Shi Jinhong Weibang Chemical CO., Ltd. - China Import Guide
Before ordering, verify the caustic soda flake’s purity and impurity levels, particularly NaOH content, sodium carbonate, and iron oxide, as these directly impact performance in industrial applications. Request a certificate of analysis to confirm compliance with GB209-2006 standards, and ensure the supplier’s laboratory testing protocols meet your quality thresholds. Check that the product’s deliquescent nature aligns with your storage capabilities.
Confirm logistics details, including packaging type (25 kg bags or 1-ton bulk bags) and container capacity, as these affect shipping costs and handling requirements.
