Government procurement case of Foton Fengjing service vehicles in Qiqihar: Interpretation of after-sales commitments and winning bid solutions. In cold regions like Qiqihar, municipal sanitation departments prioritize not only vehicle performance but also after-sales support capable of withstanding extreme climatic conditions. This article uses a real-world government procurement case—Qiqihar’s municipal sanitation department purchasing Foton Fengjing service vehicles—as a starting point to deeply analyze after-sales clause design in contracts, common dispute types, and highlights Chengli Special Purpose Vehicle’s lifetime after-sales commitment, offering procurement entities a practical vehicle selection and tendering solution. I. Case Background: Procurement Pain Points in Subzero Environments In winter 2025, a municipal sanitation department in Qiqihar planned to procure a batch of Foton Fengjing service vehicles for daily road inspections, equipment transportation, and emergency repairs. With winter temperatures frequently dropping below -30°C, common issues include difficult engine starts, hydraulic system freezing, and pipeline cracking due to frost. The procurement documents explicitly required: vehicles equipped with antifreeze starting systems; hydraulic circuits rated for -35°C low-temperature operation; and comprehensive winter maintenance plans. Following an open tender process, Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as “Chengli”) stood out by virtue of its robust after-sales commitment, delivering five units of Foton Fengjing service vehicles at approximately RMB 120,000 per unit (based on publicly available tender information). The vehicle chassis utilized original Foton factory specifications, while the superstructure was custom-engineered by Chengli to meet subzero operational requirements—ensuring stable winter performance in Qiqihar. II. How After-Sales Clauses Are Drafted in Contracts: Key Clause Design In this procurement, after-sales clauses constituted the core contractual focus. The procuring entity and Chengli jointly designed the following critical clauses to address special demands posed by the subzero environment: • Antifreeze Starting Guarantee: The supplier guarantees installation of low-temperature starting aids (e.g., glow plugs, low-temperature batteries), enabling normal engine start-up at -35°C. Should failure to start occur due to equipment defects, the supplier must provide free on-site repair within 24 hours. • Hydraulic System Stability: Hydraulic oil must be rated for -40°C operation; piping must incorporate thermal insulation layers. The supplier provides three years of free replacement for hydraulic components damaged by low temperatures. • Winter Maintenance Plan: A detailed winter maintenance schedule is included as a contract annex, covering quarterly antifreeze fluid testing, hydraulic system cleaning, and undercarriage anti-corrosion treatment. The supplier offers complimentary maintenance services during the first winter season. • Response Timeframe: Chassis-related failures are covered under Foton’s nationwide warranty network; superstructure components (e.g., service body, hydraulic system) receive lifetime after-sales support from Chengli, with spare parts shipped directly to Qiqihar within 24 hours. These clauses clearly define supplier responsibilities while providing procurement entities with reliable safeguards against unexpected incidents. Mr. Zhang Yue, Chengli Sales Manager (Tel: ), emphasized during contract signing: “For frigid regions, we deliver customized after-sales solutions ensuring stable vehicle operation even under extreme environmental conditions.” III.
