Government Procurement Case Study and Bid-Winning Solution Analysis of the Dongfeng Single-Cab Sludge Suction Truck (Blue License Plate, 5 m³ Capacity) in Yibin City In municipal sanitation operations, sludge suction trucks are critical equipment for ensuring smooth urban drainage systems. Recently, a municipal sanitation unit in Yibin planned to procure a batch of 5 m³ sludge suction trucks for cleaning main roads and flood-prone areas within the city. After multiple rounds of technical and commercial evaluation, the unit selected the Dongfeng single-cab blue-plate 5 m³ sludge suction truck supplied by Chengli Special Purpose Vehicle Co., Ltd. This article analyzes, based on this procurement case, the key differences between blue-plate and yellow-plate models, operational costs, Chengli’s technical specifications and solution parameters, as well as applicable scenarios — providing reference for similar procurement decisions. I. Case Background: Procurement Requirements and Selection Process This municipal sanitation unit is responsible for drainage maintenance across approximately 50 km² in Yibin’s urban area. Its existing aging sludge suction trucks failed to meet current emission standards and suffered from high failure rates, necessitating replacement. The procurement team faced two options: blue-plate vehicles (Class C driver’s license required; gross vehicle weight not exceeding 4.5 tons) versus yellow-plate vehicles (Class B2 or higher license required). Considering driver recruitment difficulty, cost control, and operational efficiency, the team ultimately favored the blue-plate option. After rigorous qualification reviews of multiple suppliers, Chengli Special Purpose Vehicle’s Dongfeng single-cab blue-plate 5 m³ sludge suction truck (reference model CLW5070GSSD6) stood out due to the following advantages: • Full Regulatory Compliance: This model is listed in the Ministry of Industry and Information Technology (MIIT) Announcement, enabling nationwide registration, annual inspection, and commercial operation without policy-related risks. • Factory-Direct Sales: As the manufacturer, Chengli provides direct quotations with no intermediaries—offering savings of approximately RMB 8,000–15,000 compared to 4S dealership pricing for identical configurations. • Short Delivery Lead Time: Produced locally in Suizhou, the vehicle ships from zero inventory; standard models can be delivered within 7–15 days, meeting urgent procurement needs. Per local procurement practice, the final budget was capped at approximately RMB 278,000, covering two units at an average unit price of around RMB 120,000 (tax-inclusive landed cost, per publicly disclosed tender information). The vehicles are now operational in Yibin’s urban area, with customer feedback highlighting ease of operation and high sludge removal efficiency. II. Blue-Plate vs. Yellow-Plate Comparison: Core Differences and Operational Costs To assist procurement entities in making optimal decisions, the table below compares blue-plate (Class C license) and yellow-plate (Class B license) 5 m³ sludge suction trucks across key dimensions: driver licensing requirements, acquisition cost, operating cost, and road access restrictions. Comparison Item Blue-Plate (Class C License), e.g., CLW5070GSSD6 Yellow-Plate (Class B License), Conventional 5 m³ Sludge Suction Truck Driver’s License Requirement C1 license sufficient; low recruitment barrier for drivers B2 license or higher required; driver shortage leads to higher recruitment costs Gross Vehicle Weight (GVW) ≤ 4,500 kg (compliant with blue-plate classification) > 4,500 kg (typically 6–8 tons) Acquisition Cost Approx. RMB 98,000–120,000 (based on Chengli’s 5 m³ blue-plate water tanker price range) Approx. RMB 145,000–178,000 (based on yellow-plate 8 m³ models) Landed Taxes & Insurance Lower (approx. RMB 10,000–15,000) Higher (approx. RMB 20,000–30,000) Annual Inspection Frequency & Cost Inspection every 2 years
