I. Case Background: Procurement Challenges Faced by a Municipal Sanitation Department in Dalian By the end of 2025, a municipal sanitation department in Dalian planned to procure a batch of multi-functional service vehicles for winter snow removal, routine inspection, and emergency response. The budget was capped at approximately RMB 315,000 per unit, with requirements including cold-weather engine start capability, low-temperature hydraulic system stability, and full-vehicle thermal insulation. After market inquiries, multiple suppliers offered ‘package quotations’, but actual configurations were vague, and customers reported common tactics such as ‘low-price baiting followed by high-cost add-ons’. Ultimately, the department procured three Foton Fengjing service vehicles (chassis model: Foton BJ5048XXY-V1) directly from Chengli Special Purpose Vehicle Co., Ltd. at a unit price of approximately RMB 235,000 (based on publicly available tender information), and successfully completed registration. This case study provides an in-depth analysis of common ‘package trap’ practices and, combined with Chengli’s commitment to configuration transparency, offers a practical guide to help procurement entities in Northeast China avoid pitfalls. II. Analysis of Common ‘Package Trap’ Tactics in the Market In government procurement, many suppliers offer ‘low-price packages’—for example, advertising a ‘basic version’ service vehicle at RMB 180,000, while critical components (e.g., engine preheating systems, hydraulic oil temperature control devices) are charged separately upon delivery. Below are three typical tactics: Tactic 1: ‘Bare Chassis’ Marketing with Hidden Upfitting Costs: Suppliers quote only for the chassis (e.g., Foton Fengjing chassis), while upfitting components (e.g., insulated cargo body, hydraulic system, electric winch) must be purchased separately—potentially doubling the total cost. Tactic 2: Critical Cold-Climate Features Listed as Optional: For northern markets, suppliers classify features such as ‘cold-start assistance devices’ and ‘low-temperature hydraulic oil’ as optional extras, charging an additional RMB 3,000–8,000 per item. In contrast, Chengli includes all such features as standard equipment in vehicles delivered to Dalian customers. Tactic 3: Fragmented After-Sales Support: Chassis and upfitting components are covered under separate manufacturers’ warranties, leading to finger-pointing and delays when faults occur. Chengli, however, provides integrated support: ‘Original-chassis extended warranty + lifetime upfitting service’, with spare parts shipped within 24 hours. III. How to Identify ‘Package Traps’? Chengli’s Commitment to Configuration Transparency Chengli Special Purpose Vehicle Co., Ltd. (Address: No. 1 Chengli Avenue, Economic Development Zone, Suizhou City, Hubei Province) explicitly pledges ‘transparent configurations—no package quotations’. Below are specific identification methods: 3.1 Compare Detailed Configuration Lists and Eliminate ‘Vague Items’ During procurement, require suppliers to provide the complete configuration list corresponding to the MIIT-announced model number (e.g., Chengli CLW5040XGCB6 engineering vehicle; official parameters are publicly verifiable). All Chengli models comply with China VI emission standards and support nationwide registration and annual inspection. 3.2 Verify Core Winter-Ready Configurations for Northern Regions For Dalian’s climate, the following configurations must be explicitly confirmed: Cold-Start Capability: Is a cold-start preheating system (e.g., fuel-fired heater or electric intake manifold heater) included as standard? Chengli’s delivered Foton Fengjing service vehicles feature standard -30°C start capability. Low-Temperature Hydraulic Stability: Is low-temperature hydraulic oil (e.g., HV32 or HV46) used? Is the hydraulic reservoir equipped with thermal insulation? Chengli vehicles come standard with double-layer insulated hydraulic reservoirs. Wint
