Caustic Soda – Liquid (50%) & Flake (99%) — Export from Iran
CAS No: 1310-73-2 | UN 1823 (Solid) | UN 1824 (Solution) | IMDG Class 8
Caustic Soda (Sodium Hydroxide, NaOH) is a high-purity alkali produced via membrane electrolysis of salt in Iran’s modern chlor-alkali plants. Available in two forms: Liquid (50% w/w) and Flake (99% min), our product meets international standards for chemical, textile, paper, water treatment, and industrial applications.
We supply premium-quality caustic soda from reliable Iranian producers, offering consistent concentration, low impurities, and competitive export pricing. Suitable for bulk buyers across Africa, South Asia, the Middle East, and Southeast Asia.
Note: Strong alkali — corrosive to skin and metals. Handle with PPE and proper storage. Not for food or pharmaceutical use without further purification.
