I. Case Background: Municipal Sanitation Department Procurement Requirement in Deyang City In 2025, a municipal sanitation department in Deyang City, Sichuan Province, issued a procurement requirement for sludge transport vehicles, specifying blue license plate, 3-cubic-meter capacity sludge tipper trucks for enclosed transportation of sludge following urban pipeline dredging operations. The procurement budget was capped at approximately RMB 137,000 (based on publicly available tender information), with mandatory compliance to China VI emission standards, maneuverability within urban areas, and full regulatory certification to ensure smooth vehicle registration. After comprehensive comparison and formal tendering procedures, the department selected the Dongfeng D6 chassis-based sludge tipper truck (model CLW5070GSSD6) manufactured by Chengli Special Purpose Vehicle Co., Ltd. This case study focuses on how vehicle regulatory compliance was verified via the MIIT (Ministry of Industry and Information Technology) Announcement system during procurement, and outlines key elements of the winning bid solution. II. MIIT Announcement Verification Process: Ensuring Vehicle Registration Eligibility Regulatory compliance verification through official MIIT announcements is the first critical checkpoint in government procurement. Below is the standardized verification procedure adopted by the Deyang procurement team: • Access the MIIT Website: Visit the Equipment Industry Development Center website of the Ministry of Industry and Information Technology, and enter the 'Announcement System for Road Motor Vehicle Manufacturers and Products'. • Enter Vehicle Model: Input 'CLW5070GSSD6' — the officially registered model number for Chengli’s sludge tipper truck. • Verify Key Parameters: Cross-check the following parameters listed in the announcement: – Gross Vehicle Weight (GVW): 7,360 kg (within blue license plate limit) – Rated Payload Capacity: ~3,000 kg (corresponding to 3 m³ sludge volume) – Chassis Model: Dongfeng D6 (EQ1075SJ3CDF) – Engine: Quanchai Q23-115E60 (China VI-compliant) – Overall Dimensions: Compliant with blue license plate length restriction (≤6 meters) • Confirm Announcement Batch: Verify that the announcement batch remains valid (typically valid for six months) to ensure new vehicle registration eligibility. • Download Announcement Page: Save a screenshot or PDF copy of the official announcement as an attachment for procurement documentation and subsequent vehicle registration verification at traffic management authorities. The announced parameters for Chengli’s CLW5070GSSD6 fully satisfy Deyang’s procurement requirements; furthermore, this model has already been successfully registered in multiple regions, effectively eliminating risks associated with non-compliant announcements. III. Fraudulent Announcement Cases: Common Pitfalls in Government Procurement In government procurement, suppliers have occasionally resorted to 'announcement misappropriation' or 'fraudulent announcements'. For example, an out-of-province supplier quoted approximately RMB 112,000 (per publicly available tender data), promising delivery of a blue license plate, 3-m³ sludge tipper truck — yet the actual chassis or body specifications deviated from those stated in the official announcement. This ultimately rendered the vehicle unregistrable, causing procurement delays. Common indicators of fraudulent announcements include: • Mismatch between announced model number and actual chassis model (e.g., small chassis paired with oversized tank body) • Absence of 'sludge tipper truck' classification in the announcement (e.g., misuse of water tanker truck announcement for sludge applications) • False emission standard claims (e.g., labeling China V engines as China VI) • Exceeding overall dimensional limits while still claiming 'blue license plate' eligibility In this Deyang case, the procurement team directly contacted Chengli’s official customer s
