Interpretation of the Government Procurement Case for the 3308 Yellow-Plate Sewage Treatment Vehicle in Hohhot and the Manufacturer-Direct Sales Solution. In the Hohhot region of Inner Mongolia, severe winter cold imposes stringent requirements on specialized vehicles—particularly regarding freeze-proof engine starting, hydraulic system stability, and routine maintenance. Recently, a municipal sanitation department procured a batch of 3308 yellow-plate sewage treatment vehicles through public tender to meet urban sewer network maintenance needs. Based on this case, this article analyzes price comparisons, advantages of manufacturer-direct sales, total cost of ownership (TCO) over the long term, and winter suitability—providing reference for similar procurement decisions. I. Case Background: Budget vs. Winning Bid Price According to publicly available tender information, the municipal sanitation department planned to procure two units of the 3308 yellow-plate sewage treatment vehicle, with a budget cap of approximately RMB 732,000 (tax-inclusive landed price). Following comprehensive evaluation, the delivered model was the 3308-type sewage treatment vehicle manufactured by Chengli Special Purpose Vehicle Co., Ltd., priced at approximately RMB 315,000 per unit, totaling approximately RMB 630,000—representing a savings of about RMB 23,000 against the budget. This price is lower than the concurrent market average for comparable models (approximately RMB 394,000–428,000 per unit), achieving a cost reduction of roughly 10%–15%. Referencing Chengli’s internal knowledge base and the 2026 tax-inclusive landed price system, the market reference price for an 8-cubic-meter yellow-plate sewage treatment vehicle based on a similar 3308 chassis is approximately RMB 163,000–201,000. However, considering that the 3308 model is a customized sewage treatment vehicle featuring higher-specification chassis and upper-body configurations, the final transaction price of RMB 355,000 per unit falls within a reasonable range—and remains below quotations for comparable industry products.

How Much Lower Than Market Average? Where Does Manufacturer-Direct Savings Come From? As a manufacturer-direct enterprise, Chengli Special Purpose Vehicle demonstrated significant pricing advantages in this procurement. Specifically, cost savings were realized across the following areas: • No Middleman Markup: Under traditional 4S dealership distribution models, dealers typically add a markup of 10%–20%. Chengli engages directly with procurement entities, eliminating intermediaries—yielding savings of approximately RMB 8,000–15,000 per unit versus 4S-channel equivalents with identical specifications. • Comprehensive Regulatory Approvals & Localized Production: The 3308-type sewage treatment vehicle utilizes Dongfeng chassis (e.g., models under the CLW5070GSSD6 announcement system) and is produced locally in Suizhou, enabling zero-inventory shipment. Standard models can be delivered within 7–15 days, avoiding additional costs associated with extended customization lead times. • Transparent Configuration: Chengli does not offer bundled pricing packages. All configurations—including hydraulic systems, freeze-protection components, and sewage tank materials—are custom-built strictly per official announcements and customer requirements, eliminating hidden fees.
