Case Study and Winning Bid Strategy for the Baoji Municipal Government Procurement of Dongfeng Single-Cab, Blue-License-Plate, 5-cubic-meter Sewer Cleaning Trucks. In municipal sanitation, sewer cleaning trucks are essential equipment for maintaining urban drainage systems, and their procurement often involves complex compliance procedures. This article analyzes a real procurement case from a municipal sanitation department in Baoji, providing an in-depth interpretation of the Dongfeng single-cab, blue-license-plate, 5-cubic-meter sewer cleaning truck — covering MIIT announcement verification, risks of fraudulent announcements, Chengli announcement number verification methods, and consequences of non-compliance — delivering a practical, actionable winning bid strategy. All information is based on publicly available tender data and the Chengli Special Purpose Vehicle Knowledge Base. I. Project Background and Procurement Requirements In early 2026, an environmental maintenance unit in a Baoji subdistrict needed to procure a batch of blue-license-plate sewer cleaning trucks to address urban flooding during the rainy season, due to aging municipal drainage pipelines. The procurement budget was capped at approximately RMB 171,000 (based on local publicly disclosed tender information), with requirements specifying: Dongfeng single-cab chassis, tank capacity of 5 cubic meters, compliance with China VI emission standards, and nationwide registration and annual inspection eligibility. After preliminary screening, Chengli Special Purpose Vehicle entered the shortlist thanks to its comprehensive MIIT announcements and lifetime after-sales service system. Key Requirements: Chassis: Dongfeng single-cab; operable with Class C driver’s license (blue license plate) Capacity: 5 cubic meters — suitable for operations in narrow streets Emission Standard: China VI Delivery: Standard model delivery within 15 days After-Sales Service: Nationwide chassis warranty; lifetime upfit service II. MIIT Announcement Verification Process: Avoiding Fraudulent Announcement Traps In government procurement, legal MIIT announcement status is a prerequisite for vehicle registration. Below is the standard verification procedure, using Chengli model CLW5070GSSD6 (a water-sprinkling truck) as an example — the announcement logic applies identically to sewer cleaning trucks: • Visit the official MIIT website: Access the Road Motor Vehicle Manufacturers and Products Announcement Query System. • Enter the announcement number (e.g., CLW5070GSSD6) to retrieve key parameters including chassis model, emission standard, and wheelbase. • Cross-check critical data: tank volume, rated payload, and curb weight must align precisely with procurement specifications. • Confirm manufacturer name: The listed producer must be “Chengli Special Purpose Vehicle Co., Ltd.” — avoid counterfeit or rebadged vehicles. • Verify status: Ensure the announcement is marked “Effective”, not “Suspended” or “Revoked”. According to the Chengli Knowledge Base, all Chengli models comply with China VI standards and carry complete, valid MIIT announcements; customers can rapidly verify compliance using the above steps. III. Case Study of Fraudulent Announcement: A Costly Lesson In 2025, a county-level sanitation bureau purchased a 5-cubic-meter sewer cleaning truck without verifying the MIIT announcement, sourcing it through an unauthorized channel. The result: • Registration Failure: Mismatch between announced and actual chassis led the traffic management authority to reject license plate issuance. • Failed Annual Inspection: Emission data falsification resulted in fines upon road use. • Maintenance Difficulties: The upfit manufacturer became unreachable; incompatible parts rendered the vehicle inoperable and idle. Ultimately, the unit had to reissue the tender, incurring losses of approximately RMB 200,000. This case underscores the critical importance of announcement verification. IV. How to Verify
