Government Procurement Case and Announcement Verification Analysis of the EHY5045TWCE6 Sewage Treatment Vehicle with 3308mm Wheelbase in Kunming In Kunming’s climate—characterized by frequent rainy seasons and high humidity—the municipal sanitation department’s demand for sewage treatment vehicles is steadily increasing. Recently, a municipal sanitation department procured an EHY5045TWCE6 sewage treatment vehicle (3308mm wheelbase) to handle high-load operations during the rainy season and routine sewage cleaning tasks. This article uses this case as a starting point to detail announcement verification procedures, methods for identifying fraudulent announcements, and the advantages of Chengli’s official announcement numbers—providing practical reference for procurement decision-making. I. Case Background: Procurement Requirements under Kunming’s Humid and Hot Climate Kunming is located on the Yunnan-Guizhou Plateau, where the rainy season spans May to October and annual precipitation averages approximately 1,000 mm. Such humid and hot conditions impose higher requirements on vehicle corrosion resistance and sealing component durability. The municipal sanitation department oversees sewage discharge and cleaning along urban arterial roads and low-lying areas, necessitating procurement of a sewage treatment vehicle with a 3308mm wheelbase, with a budget capped at approximately RMB 341,000. Following the tender process, the EHY5045TWCE6 model was selected. Post-delivery feedback from the customer confirmed stable performance under high-frequency, high-load rainy-season operations; its anti-corrosion coating effectively withstands the region’s high humidity, and its sealing components demonstrate durability suitable for long-term use. II. Announcement Verification Procedure: How to Confirm Compliance of the EHY5045TWCE6 Model In government procurement, announcement verification is critical to ensure legal registration, annual inspection, and operational compliance of the vehicle. Below are the steps for querying the Ministry of Industry and Information Technology (MIIT) vehicle announcement: 1. Visit the MIIT Website: Access the MIIT Equipment Industry Development Center’s “Road Motor Vehicle Manufacturers and Products Announcement Query System.” 2. Enter Parameters: Input “EHY5045TWCE6” into the Announcement Model field to retrieve complete technical specifications submitted by Chengli Special Purpose Vehicle Co., Ltd. 3. Verify Key Information: Cross-check critical data including wheelbase (3308 mm), engine model, emission standard (China VI), gross vehicle weight, and rated payload capacity. For example, the CLW5070GSSD6 water-sprinkling truck model explicitly defines tank volume and chassis configuration in its official announcement. 4. Confirm Announcement Status: Ensure the announcement status is marked as “Valid,” avoiding expired or suspended entries. III. Fraudulent Announcement Cases and Chengli Announcement Number Verification Methods Fraudulent announcements occasionally occur in special-purpose vehicle procurement. For instance, some suppliers claim their vehicles possess official announcement qualifications, yet actual MIIT queries reveal mismatched models or tampered parameters—resulting in customers’ inability to register the vehicles. As one of China’s largest special-purpose vehicle manufacturers, Chengli Special Purpose Vehicle Co., Ltd. maintains 108 fully verifiable, publicly accessible MIIT announcement numbers—including CLW5070GSSD6 and CLW5180GSSD6—with complete technical parameters officially filed.
