Case Background: Municipal Sanitation Department Procurement in Jiujiang City. In the second half of 2025, a municipal sanitation department in Jiujiang City, Jiangxi Province (hereinafter referred to as the 'Procuring Entity') planned to procure a batch of sewage treatment vehicles for urban sewer network cleaning, emergency sewage discharge, and river remediation operations. The public tender documents explicitly stipulated that the vehicles must comply with China’s National VI emission standards and possess complete MIIT (Ministry of Industry and Information Technology) announcement parameters to ensure smooth vehicle registration, annual inspection, and road operation licensing. After multiple rounds of technical evaluation and commercial negotiations, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli') delivered several Dongfeng Yizhan-style sewage treatment vehicles. This model is built on a Dongfeng chassis and features an independently designed sewage separation system developed by Chengli. Drawing upon actual feedback from the Procuring Entity, this article provides an in-depth analysis—focused on annual inspection compliance—of this case, and explains why full MIIT announcement compliance constitutes a non-negotiable requirement in government procurement. Annual Inspection Compliance: The 'Line of Life and Death' in Government Procurement In special-purpose vehicle procurement, annual inspection compliance is the most frequently overlooked—and yet most critical—aspect. Many procuring entities focus solely on price, configuration, and delivery timelines during vehicle selection, neglecting whether the vehicle can pass the public security traffic management bureau’s (traffic police) announcement verification and annual inspection. Vehicles lacking official MIIT announcements—or those whose actual parameters deviate from announced specifications—face severe consequences, including inability to register, failure to pass annual inspections, or even mandatory scrapping. According to relevant MIIT regulations, all special-purpose motor vehicles intended for road use must be listed in the 'Announcement of Road Motor Vehicle Manufacturers and Products', and their actual parameters—including overall dimensions, curb weight, and emission standard—must strictly match those published in the Announcement. For this delivery, Chengli rigorously manufactured the Dongfeng Yizhan-style sewage treatment vehicles in strict accordance with the corresponding MIIT Announcement (e.g., model CLW5070GSSD6), ensuring every unit could successfully complete registration and related procedures at local traffic management bureaus. During acceptance, the Procuring Entity specifically noted: 'We previously purchased a batch of non-standard modified sewage treatment vehicles; however, license plate registration was delayed for three months due to announcement-related issues, forcing us to return them to the manufacturer. This time, Chengli provided fully announced-compliant vehicles—vehicle inspection through license plate issuance took only one week.' Lessons from Non-Compliant Vehicles: A Real-World 'Pitfall' Case In 2023, a municipal sanitation department in an eastern Chinese city procured five 'low-cost' sewage treatment vehicles at approximately RMB 120,000 per unit (based on publicly available tender data)—significantly below market price. Upon delivery, serious discrepancies were discovered: the chassis modifications exceeded permitted length limits, violating announced dimensional parameters; although labeled as National VI compliant, the engine model was not included in the local environmental protection authority’s approved directory. Consequently, these vehicles failed formal license plate registration and could only operate within enclosed industrial parks—rendering them completely unfit for on-road operations. Ultimately, the Procuring Entity had to reissue the tender, incurring an estimated loss of RMB
