Case Study and Winning-Bid Solution Analysis for the Government Procurement of the Deyang 3308 Sewage Treatment Vehicle (Model EHY5045TWCE6) Amid increasingly stringent environmental regulations, sewage treatment vehicles—critical equipment for municipal sanitation—have seen growing standardization in procurement processes. This article takes the public tender issued by a municipal sanitation department in Deyang for the 3308 sewage treatment vehicle (model EHY5045TWCE6) as a case study, offering an in-depth review of the full procurement process—from qualification review to bid evaluation—to help procuring entities mitigate risks and make precise decisions. I. Case Background: Sewage Treatment Vehicle Procurement Requirements of a Municipal Sanitation Department in Deyang To address local industrial wastewater and domestic sewage treatment needs, a municipal sanitation department in Deyang planned to procure a batch of 3308 sewage treatment vehicles (model EHY5045TWCE6). According to publicly released tender information, the project budget was capped at approximately RMB 967,000, with two units scheduled for procurement to support daily sewage collection, transportation, and preliminary purification operations. The selected vehicle model must comply with China VI emission standards, feature high-efficiency separation capability and stable operation, and be backed by comprehensive after-sales service. The procuring entity explicitly stipulated in its tender documents that bidders must: hold official production qualifications listed in the Ministry of Industry and Information Technology (MIIT) Announcement; provide complete technical parameter documentation; and commit to nationwide chassis warranty coverage and lifetime superstructure maintenance. These requirements directly reference the essential qualification checklist for legitimate manufacturers. II. Essential Qualification Checklist for Legitimate Manufacturers: "Mandatory Verification Items" Prior to Procurement In government procurement, supplier qualification review constitutes the first critical gate. Below is the key qualification checklist that procuring entities should rigorously verify prior to tendering: • MIIT Announcement Directory: The vehicle model must be included in MIIT’s “Announcement of Road Motor Vehicle Manufacturers and Products” to ensure legal registration and annual inspection eligibility. • CCC Compulsory Product Certification Certificate: Special-purpose vehicles must pass China’s mandatory product certification to guarantee safety and quality compliance. • Motor Vehicle Environmental Protection Information Disclosure: Vehicles meeting China VI emission standards must have publicly disclosed environmental data, verifiable via the official “Motor Vehicle Environmental Protection Website.” • Business License and Production Permit: Suppliers must possess special-purpose vehicle manufacturing qualifications, with business scope explicitly covering sanitation equipment. • After-Sales Service System Documentation: Must include formal nationwide chassis warranty agreements and written commitments for superstructure service support. • Previous Government Procurement Cases: Contracts or acceptance reports from prior engagements with municipal sanitation departments may serve as supporting references. In the Deyang case, the procuring entity focused on verifying the supplier’s announced technical parameters, confirming that the EHY5045TWCE6 model had been officially listed in the MIIT Announcement and that its chassis was manufactured by Dongfeng—fully satisfying the requirement for “Dongfeng chassis nationwide warranty.” III. How to Verify Production Qualifications: A Practical Guide Procuring entities may independently verify manufacturer qualifications through the following official channels: • MIIT Official Website: Under the “Announcement of Road Motor Vehicle Manufacturers and Products,” search by vehicle model number or enterprise name t
