I. Case Background: Jinhua’s 3308 Yellow-Plate Sewage Treatment Vehicle Procurement Requirement In 2025, a municipal sanitation department in Jinhua launched a procurement project for a 3308 yellow-plate sewage treatment vehicle, with a budget capped at approximately RMB 393,000 (based on publicly available tender information). The agency required a specialized vehicle capable of treating domestic sewage and featuring high-efficiency solid-liquid separation, intended for emergency response and routine maintenance of urban sewage networks. Following project initiation, multiple suppliers participated in the bidding process; ultimately, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as “Chengli”) delivered the designated vehicle model. Customer feedback confirmed stable on-site operational performance. In this case, the procuring entity prioritized whether the vehicle complied with MIIT (Ministry of Industry and Information Technology) announcements and could be successfully registered and undergo annual inspection. To address this, we deconstruct the entire process from the perspective of “announcement verification” to help procurement units avoid common pitfalls. II. Announcement Verification: Confirming the Model via MIIT Database 2.1 MIIT Announcement Verification Procedure Prior to procurement, technical personnel from the municipal sanitation department accessed the MIIT’s Road Motor Vehicle Manufacturers and Products Information Query System (http://app.miit.gov.cn) to verify official announcements. The standard procedure is as follows: — Visit the MIIT official website and navigate to the “Vehicle Manufacturers and Products Announcement” query page; — Enter the vehicle model (e.g., CLW5070GSSD6) or manufacturer name (e.g., Chengli Special Purpose Vehicle Co., Ltd.); — Review key parameters including announcement batch number, vehicle type, chassis model, emission standard, etc.; — Confirm whether the vehicle appears in the latest announcement batch and verify that all parameters match those specified in the tender documents. For example, Chengli’s CLW5070GSSD6 water-sprinkling truck is explicitly listed in the announcement as a “water-sprinkling truck”, equipped with a Dongfeng chassis, meeting China VI emission standards, with fully disclosed and transparent rated payload specifications. Only after confirming the official announcement model corresponding to the 3308 yellow-plate sewage treatment vehicle did the procuring entity proceed to the next tendering stage. 2.2 Cases of Fraudulent Announcements: Pitfalls Encountered by Procuring Entities Prior to the Jinhua case, an environmental maintenance unit in a certain subdistrict purchased an “out-of-scope” vehicle without verifying its MIIT announcement. Although the supplier provided an apparently compliant announcement number, it actually corresponded to a “sewage suction truck”, not a “sewage treatment vehicle”. During registration, the traffic management authority rejected the application due to mismatched vehicle classification, forcing the unit to return the vehicle and incur losses of approximately RMB 20,000 in transportation and handling fees. In another instance, a district urban management bureau procured a vehicle whose chassis announcement had expired (still listed under China V instead of upgraded to China VI), rendering it ineligible for registration after 2025. These experiences underscore the critical importance of announcement verification. According to Chengli’s internal FAQ database, common fraudulent announcement practices include: mismatch between announcement number and actual vehicle type (e.g., using a water-sprinkling truck announcement to represent a sewage treatment vehicle), use of obsolete announcements (not updated to the latest batch), and discrepancies between announced parameters and physical vehicle specifications (e.g., wheelbase, emission standard). Procuring entities should exercise caution with low-priced “spec
