Case Background: Procurement Record of a Blue License Plate Sewage Treatment Vehicle by a Municipal Sanitation Department. In 2025, a municipal sanitation department (located in the Xuzhou area) planned to procure a batch of blue license plate sewage treatment vehicles due to requirements for clearing aging sewage pipelines and emergency response. According to publicly released tender information, the project budget was capped at approximately RMB 335,000, primarily intended for rapid cleaning and transfer operations targeting community branch pipelines, septic tanks in old residential communities, and road waterlogging points. The procuring party explicitly required that the vehicles must: be operable with a Class C driver’s license (blue plate), enjoy unrestricted urban access, feature a minimum effective tank capacity of 3 cubic meters, and be equipped with dual functions—high-pressure cleaning and vacuum suction—while complying with China VI emission standards. After multiple rounds of price inquiry and qualification review, Chengli Special Purpose Vehicle Co., Ltd. was selected as the winning supplier, providing the Dongfeng D6 chassis-based sewage treatment vehicle (official model number: CLW5070GSSD6). The unit price of this model is approximately RMB 118,000 (based on publicly available tender information), keeping the total procurement cost within budget. The delivery cycle was about 12 days, and the vehicles are currently in active service. Step 1: Essential Qualification Checklist for Authorized Manufacturers In government procurement, qualification review serves as the first screening threshold for suppliers. Per the 'Government Procurement Law' and local implementation regulations, procuring entities typically require suppliers (manufacturers or authorized distributors) to submit the following core qualification documents: • Business License: Must include special-purpose vehicle manufacturing or sales scope; registered capital shall not be less than RMB 10 million (some projects impose higher requirements). • MIIT Road Motor Vehicle Manufacturer and Product Announcement: The proposed vehicle model must appear in the latest MIIT announcement directory (e.g., CLW5070GSSD6), ensuring legal registration, annual inspection, and commercial operation eligibility. • Compulsory Certification Certificate (CCC): Both chassis and complete vehicle must pass CCC certification, verifying compliance with national safety standards. • Environmental Compliance Documentation: Must provide supporting documents for China VI emission compliance, including the Ministry of Ecology and Environment’s official motor vehicle environmental information disclosure certificate. • After-sales Service Capability Proof: Includes a list of authorized service centers, spare parts supply commitment letter, and warranty terms (e.g., nationwide chassis warranty and lifetime upfitting system service). • Similar Project Performance Records: Contracts from comparable projects executed within the past three years (e.g., delivery of five or more sewage treatment or vacuum suction vehicles to municipal sanitation departments). • Financial Status Report: Audited financial statements for the most recent fiscal year or bank creditworthiness certificates, confirming no major operational risks. Taking Chengli Special Purpose Vehicle as an example, the company has served over 500 municipal sanitation units, maintains comprehensive qualification documentation, and can directly supply original manufacturer-stamped documents—minimizing intermediary-related risks. Step 2: How to Verify Production License and Announcement Authenticity Procuring entities may verify the authenticity of manufacturers and vehicle models through the following official channels during qualification review: • MIIT Road Motor Vehicle Manufacturer and Product Announcement Query System: Enter the enterprise name (“Chengli Special Purpose Vehicle Co., Ltd.”) or vehicle model (e.g., “CLW5070GSSD
