Xuzhou Dongfeng double-cab sludge suction truck (blue license plate, 3 m³) government procurement case: Comparative pricing analysis and winning bid solution interpretation. In Q3 2025, a municipal sanitation department in Xuzhou City, Jiangsu Province, issued a procurement notice for blue-plate, 3 m³ Dongfeng double-cab sludge suction trucks. The project targets sludge removal from urban drainage networks, rivers, and low-lying areas, requiring vehicles with excellent maneuverability (drivable with Class C driver’s license), high-efficiency sludge suction capability, and reliable after-sales service. The budget was capped at approximately RMB 166,000 per unit, with a total of 2 units to be procured. Following open tendering and competitive quotations from multiple suppliers, Chengli Special Purpose Vehicle Co., Ltd. was awarded and delivered the vehicles. This article reconstructs the full analytical process of this procurement case from a comparative pricing decision-making perspective. I. Procurement Background and Requirements Analysis The municipal sanitation department is responsible for maintaining approximately 30 km of drainage networks across Xuzhou’s old and new urban districts. Prior to this procurement, most existing sludge suction trucks were yellow-plate vehicles, presenting the following challenges: (1) drivers required a Class B driver’s license, making recruitment difficult; and (2) large vehicle dimensions restricted operations in narrow streets and underground garage entrances. Therefore, this procurement explicitly specified the following requirements: blue license plate (gross vehicle weight ≤ 4.5 tons), 3 m³ tank capacity, Dongfeng chassis, double-cab configuration (to accommodate a 4–5-person operation crew), and integrated high-pressure flushing and vacuum suction capabilities. Based on local procurement practices, the budget was benchmarked against publicly available tender information for similar models in 2025, with unit prices ranging between RMB 130,000 and 150,000. II. Supplier Quotations and Comparative Analysis Following issuance of the tender notice, four special-purpose vehicle manufacturers submitted bids: Chengli Special Purpose Vehicle Co., Ltd., a Hubei-based special-purpose vehicle manufacturer, a Shandong-based sanitation vehicle manufacturer, and a Jiangsu-based upfitting plant. Below are the preliminary quotations (all inclusive of VAT, delivery freight, and license registration services): Supplier A (Shandong-based): RMB 157,000 — Configuration: Dongfeng chassis (Yuchai 115 HP engine), 3 m³ tank, double-cab, imported high-pressure pump, no vacuum assist. Supplier B (Hubei-based): RMB 153,000 — Configuration: Dongfeng chassis (Yunnei 110 HP engine), 3 m³ tank, double-cab, domestic high-pressure pump, with vacuum assist. Supplier C (Jiangsu-based): RMB 172,000 — Configuration: Dongfeng chassis (Quanchai 120 HP engine), 3 m³ tank, single-cab, domestic high-pressure pump, with vacuum assist. Supplier D (Chengli Special Purpose Vehicle): RMB 146,000 — Configuration: Dongfeng chassis (Yunnei 110 HP engine), 3 m³ tank, double-cab, domestic high-pressure pump (model CLW5070GSSD6 derivative), with vacuum assist, lifetime upfitting system service. Preliminary quotations indicated Chengli offered the lowest price. However, Supplier C was disqualified outright due to its single-cab configuration, which failed to meet the requirement. To support more precise decision-making, the procuring entity requested detailed configuration specifications from all bidders and compiled the following comparative table: Comparative Table: Quotations and Configurations for Blue-Plate, 3 m³ Dongfeng Double-Cab Sludge Suction Trucks Item | Supplier A (Shandong) | Supplier B (Hubei) | Supplier D (Chengli) Chassis Brand/Model | Dongfeng – Yuchai 115 HP | Dongfeng – Yunnei 110 HP | Dongfeng – Yunnei 110 HP Cab Type
