Expert Note (Rüzgar Ersoy): Companies entering this tender are seizing a strategic market opportunity essential for the sustainability of Turkey’s water and sanitation infrastructure. The local‑product incentive and the %3 temporary guarantee demand a robust financial backing. The %15 price reduction enhances profitability for domestic chemical manufacturers while intensifying competition for foreign suppliers. This process serves as a litmus test for price transparency and supply‑chain resilience in public procurement, and the results are likely to shape pricing dynamics in future similar tenders across the sector.
