Government Procurement Case of Dongfeng D6 Blue-Plate Sewage Treatment Vehicle in Baoji: Qualification Review and Winning Bid Solution Analysis In government procurement, the acquisition of sanitation vehicles—especially sewage treatment vehicles—not only hinges on equipment performance but also involves rigorous qualification reviews. This article takes the procurement of blue-plate sewage treatment vehicles by a district urban management bureau in Baoji as an example, interpreting the essential qualification checklist for compliant manufacturers, outlining the production license verification process, and showcasing Chengli Special Purpose Vehicle Co., Ltd.’s regulatory-compliant solutions and delivery experience in similar projects. In 2025, a municipal sanitation department in Baoji plans to procure a batch of blue-plate sewage treatment vehicles to address urban sewer pipeline cleaning and emergency response needs. The budget is controlled at RMB 314,000–393,000 per unit (based on publicly available tender information), requiring a Dongfeng-series chassis, China VI emission compliance, and operability with a Class C1 driver’s license. After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd. secured the delivery opportunity based on its complete set of qualifications and high cost-performance solution. I. Essential Qualifications Required for Compliant Manufacturers In government procurement, suppliers must submit the following key qualification documents to ensure product legality and compliance: • Business License: Clearly stating business scope including “special-purpose vehicle manufacturing” or “sanitation equipment production.” • MIIT Announcement Directory: The vehicle model must be listed in the MIIT’s “Announcement of Road Motor Vehicle Manufacturers and Products,” e.g., Chengli models such as CLW5070GSSD6. • CCC Certification: China Compulsory Certification, ensuring compliance with national vehicle safety standards. • Environmental Protection Information Disclosure: For China VI emission-compliant models, an environmental information disclosure sheet must be provided with each vehicle. • After-Sales Service Commitment: Terms including nationwide chassis warranty and lifetime upfit service. • Tax Payment & Social Security Records: Proof of stable corporate operation, typically covering the most recent three months. As one of China’s largest special-purpose vehicle manufacturers, Chengli Special Purpose Vehicle Co., Ltd. maintains 946 certified product entries across 44 categories, all fully listed in official announcements, and can provide a complete qualification package. II. How to Verify Production License Procuring entities may verify a manufacturer’s production license via the following steps: • Visit the MIIT Official Website: Navigate to the “Announcement of Road Motor Vehicle Manufacturers and Products” search portal. • Enter the Manufacturer Name: e.g., “Chengli Special Purpose Vehicle Co., Ltd.”, then review its announcement number and validity period. • Cross-check Vehicle Specifications: Confirm that the model (e.g., CLW5070GSSD6) matches procurement requirements—including chassis type, wheelbase, gross vehicle weight, etc. • Validate Environmental Compliance: Input the model into the “Motor Vehicle Environmental Protection Network” to verify China VI emission registration status. All Chengli models are fully approved under the MIIT Announcement and registered for China VI emissions; customers may conduct remote verification anytime to ensure transparency and compliance. III.
