Government Procurement Case and Bid-Winning Solution Analysis for the CN6 Dongfeng Sewage Treatment Vehicle with 3308 mm Wheelbase in Linfen City I. Case Background — Originating from a Municipal Sanitation Department’s Procurement Requirement in Linfen In 2025, a municipal sanitation department in Linfen City, Shanxi Province, issued a procurement tender for sewage treatment vehicles. The department is primarily responsible for sewer network cleaning and emergency response operations across urban and surrounding rural areas. Its existing equipment is outdated and inefficient, necessitating the urgent acquisition of a reliable, high-performance sewage treatment vehicle. According to publicly released tender information, the budget ceiling was approximately RMB 391,000, and the vehicle must comply with China VI emission standards and feature a 3308 mm wheelbase to suit local road conditions. After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd.’s proposal was selected and successfully implemented, receiving positive feedback from the client. This case reflects common pain points in current municipal sanitation procurement: how to select a cost-effective vehicle within budget while avoiding price markups imposed by intermediaries. Below, we provide an in-depth analysis covering intermediary identification, direct manufacturer procurement strategies, and implementation details. II. Common Intermediary Sales Tactics and Identification Pitfalls During government procurement processes, procurement personnel frequently encounter various tactics employed by intermediaries—aimed either at inflating prices or offloading obsolete inventory. Below are typical pitfalls and corresponding countermeasures: Tactic 1: “Factory-direct pricing is higher than 4S dealership pricing—but we have ready stock.” In reality, Chengli Special Purpose Vehicle, as a direct manufacturer, offers the same configuration at RMB 8,000–15,000 less than 4S channels. The so-called “ready stock” claimed by intermediaries often consists of aged inventory or mismatched configurations. Tactic 2: “This model lacks complete official announcements; additional fees are required for registration.” All Chengli models possess complete official announcements and fully comply with China VI emission standards, enabling nationwide registration, annual inspection, and commercial operation without restrictions. Intermediaries frequently exploit this claim to impose unnecessary surcharges. Tactic 3: “We offer lifetime after-sales service—but spare parts are self-funded.” Chengli guarantees: Dongfeng chassis covered under nationwide joint warranty; superstructure covered by lifetime service; spare parts dispatched within 24 hours. By contrast, intermediaries’ “lifetime after-sales service” is often nominal and unsubstantiated. In the Linfen case, the procuring entity initially engaged an intermediary quoting approximately RMB 425,000—including an alleged “expedited processing fee.” Upon contacting Chengli directly via official channels, they discovered that the identical configuration could be delivered for RMB 324,000–358,000, resulting in nearly RMB 60,000 in savings.
