1. Case Background: Procurement Requirement of a Municipal Sanitation Department in Hefei — In 2025, a municipal sanitation department in Hefei planned to procure a batch of sewage treatment vehicles for urban sewer network cleaning and emergency response. The project budget was approximately RMB 684,000, with plans to purchase two new Dongfeng sewage treatment vehicles. Key evaluation criteria included compliance with MIIT (Ministry of Industry and Information Technology) vehicle announcements, chassis performance, and after-sales service. Following a public tender, Chengli Special Purpose Vehicle Co., Ltd. won the bid with a unit price of approximately RMB 295,000 (per publicly available tender information), delivering two new Dongfeng-chassis sewage treatment vehicles. In this case, the procuring entity’s top priority was: How to verify vehicle specifications via the MIIT announcement to ensure normal registration, annual inspection, and commercial operation? This article uses models such as Chengli CLW5070GSSD6 as examples to detail the announcement verification process and compare them with fraudulent announcement cases, helping procurement entities mitigate risks. 2. MIIT Announcement Verification Steps: From Model Selection to Registration — In government procurement, announcement verification is the first step to ensure vehicle legality. Below is the standard verification procedure: Step 1: Obtain the Announcement Model Number — The procuring entity must confirm that the supplier-provided model appears in the MIIT’s ‘Announcement of Road Motor Vehicle Manufacturers and Products’. For example, Chengli Special Purpose Vehicle’s CLW5070GSSD6 (5-cubic-meter water sprinkler) and CLW5180GSSD6 (15-cubic-meter water sprinkler) are both listed announcement models, searchable online. Step 2: Access the MIIT Official Website — Log in to the MIIT Road Motor Vehicle Manufacturer and Product Information Query System (zyqc.miit.gov.cn) and enter either the announcement model number or the manufacturer name. Step 3: Verify Critical Parameters — The query results must include: vehicle model, chassis model, engine model, emission standard, overall dimensions, curb weight, gross vehicle weight, tank capacity, etc. For instance, the official announcement for the new Dongfeng sewage treatment vehicle must explicitly state ‘China VI emission standard’ and ‘effective tank capacity of 5 cubic meters’. Step 4: Confirm Consistency — Cross-check announced parameters against the actual vehicle configuration to ensure no discrepancies exist in chassis, upper structure, engine, or other components. Chengli vehicles feature complete and accurate announcements aligned precisely with physical units, supporting nationwide registration and annual inspection. 3. Fraudulent Announcement Cases: Common Pitfalls and Risks — In practice, some suppliers exploit policy loopholes or information asymmetry by offering ‘cloned-plate’ vehicles or units with non-compliant announcements. Below are two typical fraudulent announcement cases: Case A: Fabricated Announcement Model Number — A subdistrict environmental maintenance unit purchased two compact sewage treatment vehicles. The supplier claimed ‘full announcement compliance’, but the procuring entity failed to verify independently. During registration, it was discovered that the announced model number did not exist in the MIIT system, rendering the vehicles unregistrable. Ultimately, the chassis had to be replaced, resulting in losses of approximately RMB 50,000. Case B: Tampered Parameters — A district urban management bureau tendered for ten water sprinklers. The supplier’s submitted announcement indicated a tank capacity of 8 cubic meters, yet on-site measurement revealed only 6.5 cubic meters. Investigation confirmed the supplier had altered the official announcement parameters without authorization. During annual inspection, the vehicles were rejected and required factory rework, causing a three-month proje
