I. Case Background: Procurement Requirements of a Municipal Sanitation Department in Fuyang City In 2025, a municipal sanitation department in Fuyang City, Anhui Province (hereinafter referred to as the 'Procuring Entity') planned to procure a batch of sewer cleaning trucks to address sediment removal needs in urban drainage pipelines and culverts. Following preliminary research, the Procuring Entity specified the following requirements: • Chassis with Dongfeng double-cab cab for efficient crew and tool transportation; • Tank capacity of approximately 3 cubic meters (meeting Blue License Plate standards, operable with a Class C1 driver’s license); • Equipped with high-pressure cleaning and vacuum suction functions, suitable for operations in narrow streets; • Compliant with China VI emission standards to ensure environmental regulatory compliance; • Budget capped at approximately RMB 169,000 (based on local procurement precedents for similar vehicles). The Procuring Entity conducted an open tender to solicit proposals; ultimately, the proposal submitted by Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli') was selected, resulting in the delivery of three Dongfeng double-cab blue license plate sewer cleaning trucks. This article analyzes the core aspects of this case from the perspectives of official announcement verification, price comparison, and compliance risk assessment. II. Announcement Verification: Why It Is a Critical Procurement Step In government procurement, the Vehicle Announcement (issued by the Ministry of Industry and Information Technology — MIIT — under the 'Announcement of Road Motor Vehicle Manufacturers and Products') is the essential document ensuring legal road operation, registration, and annual inspection of vehicles. According to MIIT Announcement No. 108, Chengli models such as CLW5070GSSD6 (water-sprinkling truck) are fully listed; similarly, its sewer cleaning trucks are also officially announced. Prior to tendering, the Procuring Entity must verify announcement compliance through the following steps: • Query the Announcement Number: Visit the MIIT official website or the 'Road Motor Vehicle Manufacturer and Product Information Inquiry System', and enter either the vehicle model number (e.g., CLW5070GSSD6) or the enterprise name 'Chengli Special Purpose Vehicle Co., Ltd.' • Verify Key Parameters: Confirm that vehicle dimensions, gross vehicle weight, tank capacity, and engine model match procurement requirements. For instance, a 3-cubic-meter sewer cleaning truck must be explicitly stated in the Announcement as having an 'effective tank capacity ≤ 3 m³'. • Confirm Emission Standard: All China VI-compliant models are labeled in the Announcement as 'Emission Standard: GB17691-2018 China VI' to prevent procurement of outdated China V inventory units. • Validate Chassis Source: Dongfeng chassis must be authorized by Dongfeng Motor Corporation. Chengli offers chassis from Dongfeng, Sinotruk, and other brands; suppliers may be required to provide the chassis Certificate of Conformity. • Obtain the 'Certificate of Conformity for Whole Vehicle Manufacture': Upon contract award, the supplier must issue this certificate, which serves as the basis for vehicle registration. III. Risks of False Announcements: A Real-World Lesson In 2023, an environmental maintenance unit in a certain subdistrict incurred registration failure due to purchasing a low-cost sewer cleaning truck. Although the vehicle’s Announcement listed it as a 'water-sprinkling truck', it had been modified for vacuum suction functionality. The traffic management authority determined that 'the vehicle’s actual parameters did not match those in the Announcement' and rejected registration. As a result, the Procuring Entity suffered a financial loss of approximately RMB 80,000 and experienced a three-month project delay. Common issues associated with false announcements include: • Mismatch between announced model and ac
