Case Study: Procurement of Dongfeng Dual-Cab Blue License Plate 3-cubic-meter Sewer Cleaning Trucks by a Municipal Sanitation Department in Baoji City In autumn 2025, a municipal sanitation department in Baoji City planned to procure a batch of Dongfeng dual-cab blue license plate 3-cubic-meter sewer cleaning trucks to meet urban drainage pipeline cleaning requirements. After receiving quotations from multiple dealers, the procurement department observed substantial price discrepancies—ranging from RMB 101,000 to RMB 140,000 per unit—with varying configurations, official type-approval documentation, and after-sales service packages. To ensure optimal value for money and regulatory compliance, the department launched a rigorous comparative quotation evaluation process. Ultimately, Chengli Special Purpose Vehicle Co., Ltd. secured the order by offering transparent specifications, an OEM Dongfeng chassis, and lifetime after-sales support, successfully delivering the vehicles. This article reconstructs the quotation evaluation process based on publicly available tender information and local procurement practices, serving as a reference for industry peers. I.
