Government Procurement Case and Bid-Winning Solution Analysis for the Dongfeng Yizhan-Style Sewage Treatment Vehicle in Xinxiang City — In autumn 2025, a municipal sanitation department in Xinxiang City publicly tendered for Dongfeng Yizhan-style sewage treatment vehicles to address sewer pipe cleaning and emergency response challenges in aging urban residential communities. The project’s total budget was capped at approximately RMB 2.005 million, with plans to procure six specialized vehicles at an estimated unit price of around RMB 300,000. After multiple rounds of evaluation, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as 'Chengli') won the bid with a total contract value of approximately RMB 1.68 million. This article analyzes the case from practical procurement requirements, budget constraints, solution advantages, and common pitfalls, helping other procurement entities bypass intermediaries and engage directly with manufacturers. I. Procurement Background and Core Requirements In June 2025, the Urban Management Bureau of a district in Xinxiang City launched this project to address the following key pain points: • Frequent blockages in aging community sewer networks: requiring rapid-response vacuum suction and sewage separation equipment to prevent secondary pollution. • Limited budget: tight fiscal funding necessitated unit vehicle costs under RMB 300,000, while also qualifying for Blue-Plate (C-class driver’s license) operation and exemption from vehicle purchase tax—reducing long-term operational costs. • Delivery and after-sales assurance: demand for nationwide chassis warranty coverage, lifetime service for the superstructure, and direct shipment of spare parts within 24 hours. • Regulatory compliance: vehicles must meet China VI emission standards, possess complete official announcements, and be eligible for registration, annual inspection, and commercial operation nationwide. Per local procurement practice, Dongfeng-chassis vehicles are typically prioritized due to their dense network of repair centers and readily available parts supply across Henan Province. Chengli’s Dongfeng Yizhan-style sewage treatment vehicle (e.g., model CLW5070GSSD6, per official announcement parameters) fully met all these criteria. II. Bid-Winning Solution Analysis: How Did Chengli Win? Among three shortlisted suppliers, Chengli secured the contract at a unit price of approximately RMB 280,000, totaling roughly RMB 1.68 million—saving about RMB 134,000 against the budget. Its core competitive advantages included: 1. Direct Factory Sales, Eliminating Intermediary Markup Chengli is headquartered in Suizhou Special Purpose Vehicle Industrial Park, Hubei Province, and is an officially registered manufacturer listed by the Ministry of Industry and Information Technology (MIIT). Compared to local 4S dealers or trading companies, Chengli’s direct quotation eliminated channel-related markups of approximately RMB 8,910–16,700 per unit. The tender documents explicitly stipulated 'no subcontracting or third-party agency representation,' and Chengli participated as the original equipment manufacturer (OEM), ensuring full compliance with qualification requirements. 2. Blue-Plate Advantages and Low-Cost Operations The Dongfeng Yizhan-style sewage treatment vehicle procured in this project features a Blue-Plate configuration (gross vehicle weight ≤ 4.5 tons), enabling operation with a Class C driver’s license—eliminating the need to hire dedicated Class B drivers and saving an estimated RMB 30,000–50,000 annually in labor costs. Additionally, Blue-Plate vehicles qualify for exemption from vehicle purchase tax (approx. RMB 25,000 per unit) and face no urban traffic restrictions, significantly enhancing emergency response efficiency. 3. Flexible Payment Terms and Trade-In Policy To accommodate tight fiscal budgets, Chengli offered flexible installment payment terms: 30% upfront, with the balance paid interest-free over 12 months.
