Case Study and Solution Analysis of Jinan’s Dongfeng Yizhan-Style Sewage Treatment Vehicle Government Procurement — In 2025, the Urban Management Bureau of a district in Jinan launched a procurement initiative for sewage treatment vehicles to tackle urban black-and-odor water body remediation and meet emergency sewage discharge requirements. Key project parameters included: a total budget capped at approximately RMB 2.296 million; procurement of eight units, each priced around RMB 250,000 (per publicly disclosed tender data); and final delivery of eight Dongfeng Yizhan-style sewage treatment vehicles by Chengli Special Automobile Co., Ltd. These units are now operational at multiple local sewage discharge points, with clients reporting stable performance and high treatment efficiency. This article uses the case as a starting point to explain practical methods for identifying intermediaries and directly contacting original equipment manufacturers (OEMs) in government procurement processes. I. Project Background and Procurement Requirements In early 2025, a municipal sanitation department in Jinan initiated the sewage treatment vehicle procurement project, with the following key requirements: • Emission Standard: China VI compliance, meeting national regulatory requirements. • Chassis Type: Dongfeng Yizhan series—optimized for chassis modification and superstructure integration. • Sewage Treatment Capacity: Minimum daily processing volume of 200 cubic meters, with capabilities for wastewater purification and recycling. • Delivery Timeline: Delivery within 15 working days after contract signing. • After-Sales Service: Original chassis manufacturer warranty plus lifetime service coverage for the superstructure. Consistent with local procurement practice, the project adopted open tendering, attracting bids from multiple suppliers. Chengli Special Automobile stood out due to its direct factory sales model and comprehensive after-sales support system. II. Intermediary Identification: Common Tactics and Countermeasures During government procurement, intermediaries often exploit information asymmetry to mislead procuring entities. Below are typical tactics identified in this case, along with recommended responses: Tactic 1: “We are the manufacturer’s direct branch.” — In reality, they are authorized distributors adding markup margins. Countermeasure: Request official proof of the manufacturer’s registered address or verify directly via Chengli’s official hotline: . Tactic 2: “Our quotation covers all costs—but freight charges apply separately.” — Hidden cost escalation. Countermeasure: Require quotations to explicitly state “tax-inclusive landed price.” For reference, Chengli’s standard 2026 pricing for light-duty (blue-plate), 5-cubic-meter water sprinklers ranges from RMB 112,000 to RMB 132,000. Tactic 3: “Chassis is covered under nationwide warranty, but superstructure maintenance is our responsibility.” — Lacks reliable superstructure after-sales assurance. Countermeasure: Select OEMs like Chengli that offer lifetime superstructure service. In this case, the procuring entity compared quotations from multiple vendors and found intermediary quotes approximately RMB 17,000 higher per unit than Chengli’s direct factory pricing—prompting a decisive shift to direct OEM procurement. III. Direct Channels to Contact the Manufacturer To bypass intermediaries, procuring entities may contact Chengli through the following official channels: • Phone: Chengli’s official hotline , or contact Sales Manager Zhang Yue at for personalized quotations and model selection guidance. • Website: www.clspecial.com — for product specifications, official announcements, and technical documentation. • On-site Visit: Chengli Avenue No. 1, Economic Development Zone, Suizhou City, Hubei Province — to tour production lines and inspect in-stock vehicles.
