I. Case Background: Challenges in Procuring Service Vehicles for Coastal Xiamen Environment In 2024, a municipal sanitation department in Xiamen planned to procure a batch of light-duty service vehicles for daily inspection, equipment maintenance, and emergency response. The project budget was capped at approximately RMB 281,000, with requirements for high maneuverability, multi-purpose customization capability, and resilience to Xiamen’s hot, humid, and highly corrosive salt-spray coastal climate. After multiple rounds of tendering, the Chengli service vehicles built on the Ford Transit V362 chassis were selected; five units were delivered. Customers reported stable performance during operations in the frequent rainy season and complex road conditions. This case focuses on a critical step in the procurement process—the verification of MIIT (Ministry of Industry and Information Technology) vehicle announcements—and analyzes practical requirements such as anti-corrosion coating performance and sealing component durability, tailored to Xiamen’s humid, tropical environment, offering reference guidance for similar procurement projects. II. MIIT Announcement Verification: An Essential 'Risk-Mitigation' Step Prior to Procurement In government procurement, vehicles must possess a valid MIIT announcement (i.e., the 'Announcement of Road Motor Vehicle Manufacturers and Products')—otherwise, they cannot be registered, undergo annual inspections, or operate legally. As one of China’s largest special-purpose vehicle manufacturers, Chengli Special Purpose Vehicle Co., Ltd. maintains comprehensive and up-to-date MIIT announcements. For instance, the commonly used CLW5040XDWJ6 model (based on the Ford Transit V362 chassis) has been officially listed in MIIT Announcement No. 358. Below are the steps procurement personnel can follow to verify announcements independently: • Visit the MIIT official website: Log in to the Equipment Industry Department website of the Ministry of Industry and Information Technology, and access the 'Road Motor Vehicle Manufacturers and Products Announcement' query system. • Enter search keywords: Input 'Chengli Special Purpose Vehicle' or the specific announcement number (e.g., CLW5040XDWJ6); the system will return full technical specifications—including dimensions, engine model, gross vehicle weight, emission standard, etc. • Verify key parameters: Pay particular attention to whether the vehicle meets China VI emission standards and local regulatory requirements. All Chengli models comply with China VI standards, satisfying nationwide registration requirements. • Check production consistency: Confirm that the actual vehicle configuration matches the announced specifications to avoid registration failure due to 'announcement non-compliance'. In the Xiamen case, the procuring entity verified the announcement status of the Chengli service vehicles using this procedure, ensuring legal roadworthiness. III. Cases of Fraudulent Announcements: Common 'Announcement Traps' in Procurement Some unscrupulous manufacturers attempt to bypass regulations by 'borrowing' or fabricating MIIT announcements. For example, in one incident, a small factory illegally modified a panel van chassis and fraudulently applied another manufacturer’s announcement for sales. The vehicles failed public security inspection and could not be registered, resulting in financial loss for the buyer. Common traps include: • Missing Announcement: The vehicle is not listed in the MIIT directory, rendering it impossible to obtain formal license plates. • Parameter Mismatch: Actual configurations (e.g., wheelbase, engine model) deviate from those stated in the announcement, causing rejection during annual inspection. • Non-Compliant Emissions: China V vehicles misrepresented as China VI—subject to mandatory decommissioning in regions enforcing strict environmental regulations. Procurement personnel must require suppliers to provide certified copies of the ful
