Yantai National VI Dongfeng 3308 mm Wheelbase Sewage Treatment Vehicle Government Procurement Case and Bid-Winning Solution Analysis In 2025, a municipal sanitation department in Yantai planned to procure a batch of National VI emission-standard sewage treatment vehicles to meet the upgrading requirements of urban sewage treatment infrastructure. After conducting market research and completing the tendering process, Chengli Special Purpose Vehicle Co., Ltd. was selected as the supplier, offering Dongfeng chassis vehicles with a 3308 mm wheelbase. This case not only exemplifies government procurement’s integrated assessment of regulatory compliance, technical performance, and cost-effectiveness, but also underscores the pivotal role of official announcement verification in special-purpose vehicle procurement. This article adopts an announcement-verification–oriented analytical framework to thoroughly examine the procurement background, official announcement query procedures, risks associated with false or non-compliant announcements, and the real-world implementation of Chengli’s solution. Procurement Background and Requirements Analysis As a coastal city, Yantai imposes high adaptability requirements on sewage treatment equipment—particularly regarding narrow urban road navigation, stringent emission standards, and ease of maintenance. The procurement budget was capped at approximately RMB 343,000 (per publicly disclosed tender information), with mandatory requirements including National VI emissions compliance, Dongfeng chassis, a 3308 mm wheelbase, and high-efficiency sewage treatment capability. Leveraging complete official announcement parameters for models such as the CLW5070GSSD6 and its local service network, Chengli Special Purpose Vehicle successfully delivered three sewage treatment vehicles; customer feedback confirmed stable operational performance. MIIT Announcement Query Procedure: Ensuring Compliance — The First Critical Step In government procurement, official announcement verification is the cornerstone for mitigating subsequent registration, annual inspection, and operational risks. Below are the standard query steps: 1. Visit the MIIT Official Website: Navigate to the Equipment Industry Development Center website of the Ministry of Industry and Information Technology (www.miit.gov.cn) and locate the “Announcement of Road Motor Vehicle Manufacturers and Products” section. 2. Enter Key Information: Input either the chassis model (e.g., Dongfeng 3308 mm wheelbase) or product model (e.g., CLW5070GSSD6) into the search field to verify whether the vehicle appears in the latest announcement batch. 3. Verify Technical Parameters: Cross-check whether the announcement explicitly lists key specifications—including emission standard (National VI), wheelbase (3308 mm), gross vehicle weight, and overall dimensions—to ensure full alignment with the actual configuration. 4. Confirm Visual Consistency: Compare official announcement photographs against the physical vehicle’s exterior appearance to prevent post-delivery modifications that may cause parameter discrepancies. Prior to tendering, the Yantai procurement entity completed this verification process and confirmed that Chengli’s CLW5070GSSD6 model had been officially listed in Announcement Batch No. 350—effectively eliminating potential bottlenecks in subsequent procedures. Case of False Announcements: The ‘Hidden Pitfall’ in Procurement In the special-purpose vehicle market, false or non-compliant announcements remain a recurring issue. For instance, an environmental maintenance unit in a certain subdistrict procured a batch of water-sprinkling trucks, with the winning bidder asserting full announcement compliance. However, the delivered vehicles featured a wheelbase inconsistent with the announced parameters, rendering them ineligible for local vehicle registration at the traffic management bureau. Ultimately, the unit had to initiate a time-consuming re-applica
