Xiangyang Dongfeng New Wastewater Treatment Vehicle Government Procurement Case and Bid-winning Solution Interpretation I. Case Background: A Real Procurement Decision In 2025, a municipal sanitation department (hereinafter referred to as "the unit") planned to procure a batch of new Dongfeng wastewater treatment vehicles for emergency response and routine maintenance of urban sewage pipelines. According to publicly released tender information, the project budget was capped at approximately RMB 340,000, requiring vehicles with high-efficiency wastewater treatment capability, China VI emission standards, and a comprehensive after-sales service plan. After multiple rounds of evaluation and comparison, the unit ultimately selected products from Chengli Special Automobile Co., Ltd., delivering two Dongfeng-chassis wastewater treatment vehicles at a unit price of approximately RMB 140,000–160,000. This case not only demonstrates the standardized government procurement process but also exposes common intermediary pitfalls encountered during procurement. Core Issue: At the initial procurement stage, the unit contacted several intermediaries claiming to be "authorized manufacturers' agents." Their quotations were RMB 9,080–17,000 higher than Chengli’s official direct sales prices, and vehicle configurations were opaque. Ultimately, by contacting the manufacturer directly, the unit achieved approximately 10% cost savings. II. Common Intermediary Tactics and Identification Techniques In government procurement, intermediaries often mislead procuring entities by exploiting information asymmetry. Below are typical tactics encountered by the unit: Tactic 1: "We are a first-tier authorized Dongfeng agent; our price is definitely lower than the manufacturer’s." — In reality, intermediaries mark up prices by 15%–20% and do not provide unified after-sales service covering both chassis and superstructure. Tactic 2: "This model lacks complete official vehicle announcements; additional fees are required for registration." — All Chengli models (e.g., CLW5070GSSD6) possess complete official announcements and can be registered, inspected annually, and operated nationwide without restrictions. Tactic 3: "We offer bundled services including spare parts and customization." — Such packages often include high-margin accessories, while actual configurations remain unclear. Identification Method: Request official authorization documents directly from the manufacturer and verify authenticity via Chengli’s official hotline: . If the party cannot provide original chassis factory warranty certification, it is highly likely an intermediary. III. Direct Contact Methods and Advantages of Purchasing from the Manufacturer After identifying intermediaries, the unit contacted Chengli Special Automobile Co., Ltd. directly (address: No. 1 Chengli Avenue, Economic Development Zone, Suizhou City, Hubei Province). Specific contact methods: Official Hotline: (24-hour consultation) Sales Manager: Zhang Yue, +86 (for detailed quotations and technical specifications) Official Website: www.clspecial.com (to access vehicle announcement details and real-world case studies) Advantages of Direct Purchase: — Factory-direct sales eliminate intermediaries, saving RMB 8,000–15,000 compared to 4S-channel pricing for identical configurations; — Local production in Suizhou enables delivery within 7–15 days for standard models, with zero-inventory dispatch; — Nationwide chassis warranty (Dongfeng chassis) and lifetime superstructure service; spare parts shipped directly within 24 hours; — Complete official vehicle announcements ensure seamless registration, annual inspection, and commercial operation nationwide.
