Case Study of Chengdu’s Government Procurement of Dongfeng Double-Cab Sewer Cleaning Trucks (Blue License Plate, 3 m³): In-depth Analysis of Pricing Advantages and Winning Bid Strategy. In Southwest China—particularly in cities like Chengdu—sewer cleaning of drainage networks during the rainy season is a perennial municipal sanitation task. In 2025, a municipal sanitation department procured a batch of Dongfeng double-cab blue license plate 3 m³ sewer cleaning trucks for maintenance of aging urban pipelines. The budget was capped at approximately RMB 250,000 per unit; the winning bid price was around RMB 195,000 (per publicly available tender information), roughly RMB 20,000 lower than the market average. This pricing advantage stems from the integration of the manufacturer-direct sales model and product suitability. This article uses the Dongfeng double-cab blue license plate sewer cleaning truck supplied by Chengli Special Purpose Vehicle Co., Ltd. (hereinafter referred to as “Chengli”) as an example—specifically its CLW5040TQYD6 certified model—to explain why this solution stood out in government procurement, and analyzes its Total Cost of Ownership (TCO) under Chengdu’s humid, hot climate conditions over extended use. I. Comparison of Winning Bid Price vs. Budget: How Much Was Saved? According to publicly available tender information, the total project budget was approximately RMB 1,000,000 (for four units), with a per-unit budget of about RMB 250,000. Chengli’s winning bid price was approximately RMB 195,000 per unit—saving RMB 25,000 per unit and RMB 100,000 overall. As referenced in Chengli’s internal knowledge base, such direct-sales solutions typically cost RMB 8,000–15,000 less per unit than those purchased through 4S dealerships; thus, the observed savings align with expectations. Compared to other brands’ Dongfeng-chassis sewer cleaning trucks sold via 4S channels—which commonly range between RMB 239,000 and RMB 261,000—the manufacturer-direct model eliminates channel markups. II. How Much Lower Than Market Average? Comparative Data To illustrate the pricing advantage clearly, the table below compares mainstream market configurations against Chengli’s solution: | Item | Chengli Solution (Winning Bid Price) | Market 4S Channel Average | Savings | |------|--------------------------------------|----------------------------|---------| | Vehicle Price (incl. VAT) | ~RMB 195,000 | ~RMB 215,000 | ~RMB 20,000 | | Chassis Model | Dongfeng Double-Cab (China VI) | Dongfeng Double-Cab (China VI) | Same chassis | | Tank Capacity | 3 m³ | 3 m³ | Same specification | | Anti-Rust Coating | Full-vehicle electrophoretic coating + epoxy primer | Standard anti-rust paint | Superior (Chengli) | | Sealing Material | Oil-resistant Nitrile Rubber (optimized for humid/hot environments) | Standard rubber | Superior (Chengli) | | Delivery Lead Time | 7–15 days | 20–30 days | ~50% shorter | | After-Sales Service | Nationwide chassis warranty + lifetime superstructure service | Chassis warranty only + 1-year superstructure warranty | Superior (Chengli) | Note: Pricing data sourced from publicly available tender documents; configuration parameters based on Chengli’s CLW5040TQYD6 official announcement and internal FAQ database. III. Where Does the Manufacturer-Direct Model Save Costs? As one of China’s largest special-purpose vehicle manufacturers—with 946 product specifications spanning 44 categories—Chengli’s manufacturer-direct sales model delivers core advantages: • No intermediary markup: Eliminating distributors and 4S dealers reduces costs by RMB 8,000–15,000 per unit for identical configurations. In this case, the RMB 25,000 saving reflects both the direct-sales advantage and additional bulk-purchase negotiation leverage. • Zero-inventory shipping: Local production in Suizhou enables delivery of standard models within 7–15 days, minimizing inventory financing costs—and thereby lowering end-user pricing.
