Iranian Sulfur – High-Purity Granules (99.8%)
Sulfur Granules (S) are a high-purity, bright yellow solid produced from Iran’s major gas refineries such as South Pars, Abadan, and Asaluyeh. Our granular sulfur contains ≥ 99.8% elemental sulfur, with very low moisture and ash content — making it ideal for large-scale industrial applications in fertilizer, rubber, chemical, and water treatment industries.
We supply premium Iranian granular sulfur with consistent size (2–5 mm), free-flowing properties, and excellent storage stability. Suitable for bulk buyers across India, Southeast Asia, Africa, Latin America, and the Middle East.
Note: Combustible solid — store in dry, well-ventilated area away from heat and oxidizers. Not for direct human consumption.
