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 ultra-high-purity silica sands, and SRPMD represents a flagship product in this category. This silica sand is not merely a raw material; it is a precision-engineered product designed for applications where even trace impurities can compromise product quality. A crystal glass manufacturer in Turkey requires silica sand with iron content below 0.03% to achieve the brilliance and clarity that define premium glassware; a pharmaceutical container producer in Iraq needs silica that meets pharmacopoeia standards for leachable metals; an optical glass manufacturer in Uzbekistan requires silica with consistent refractive index and high light transmission. The department's technical team understands these sensitivities and ensures that SRPMD meets the exacting specifications of each client.
The department sources SRPMD 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, whiteness, 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 SRPMD in the grade and packaging that best suits their needs.
