1. Introduction to the Supply Chain Department at Sahi Rasa Company
The Supply Chain Department at Sahi Rasa Company has distinguished itself in the export of high-purity industrial minerals, and premium low-iron silica sand SRP represents the pinnacle of its silica portfolio. This product is not a commodity; it is a precision material engineered for applications where even trace impurities can compromise product quality. A crystal glass manufacturer in Turkey cannot tolerate iron levels above 0.06% without risking a green tint that would diminish the brilliance of its products. A pharmaceutical container producer in Iraq requires silica sand that meets pharmacopoeia standards for leachable metals. A specialty ceramic manufacturer in Uzbekistan needs consistent particle size distribution to achieve uniform sintering. The department's technical team understands these sensitivities and ensures that SRP meets the exacting specifications of each client.
The department sources SRP from selected Iranian deposits known for their exceptional purity. The raw sand is processed through advanced washing, magnetic separation, and grading to remove iron-bearing minerals and other impurities. The final product is tested for SiO₂ content, Fe₂O₃ content, particle size distribution, and moisture. Certificates of Analysis accompany every shipment, and retained samples ensure traceability.
For clients in Afghanistan, the Kurdistan Region, Iraq, Tajikistan, Uzbekistan, Armenia, Georgia, Turkey, and Syria, the Supply Chain Department at Sahi Rasa Company offers a reliable supply of SRP in the grade and packaging that best suits their needs.
