I. Case Background: Sewage Treatment Vehicle Procurement Requirement of a District Urban Management Bureau in Wuhan By the end of 2025, a district urban management bureau in Wuhan planned to procure a batch of new sewage treatment vehicles to address drainage system upgrades in old residential communities and river remediation needs. In line with local procurement practices, the budget was capped at approximately RMB 3.314 million. The vehicles were required to feature high-efficiency solid-liquid separation, sludge dewatering, and emergency sewage discharge capabilities, and must comply with China VI emission standards. The tender documents explicitly stipulated that bidders must provide official MIIT (Ministry of Industry and Information Technology) announcement documentation to ensure nationwide registration eligibility and annual inspection compliance. After preliminary screening, multiple suppliers submitted proposals; however, one supplier’s 'Dongfeng New Sewage Treatment Vehicle' was flagged by the evaluation panel as 'pending verification' due to an ambiguous MIIT announcement number and inconsistencies between its technical parameters and those published in the official announcement. Ultimately, Chengli Special Purpose Vehicle Co., Ltd. secured the order by delivering five Dongfeng-chassis sewage treatment vehicles (model reference: CLW5180GSSD6), each priced at approximately RMB 280,000 (based on publicly available tender information). Customer feedback confirmed stable vehicle operation and sludge treatment efficiency meeting expectations. This case highlights a critical pain point in government procurement: how to verify vehicle MIIT announcements. False or incomplete announcements may result in registration failure, annual inspection rejection, or even legal liability. This article uses Chengli products as an example to detail the step-by-step verification process, helping procurement entities avoid pitfalls. II. MIIT Announcement Verification Procedure: From 'Unable to Understand' to 'Capable of Verification' Based on the 108 MIIT announcement entries in our knowledge base (e.g., CLW5070GSSD6, CLW5180GSSD6, etc.), the standardized verification process is as follows: 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), then locate the 'Announcement of Road Motor Vehicle Manufacturers and Products' section. 2. Enter the Announcement Number: Announcement numbers typically follow the format 'CLW5180GSSD6'. For instance, for Chengli’s CLW5180GSSD6 water tanker, entering 'CLW5180' into the search box retrieves the corresponding batch. 3. Verify Key Parameters: Focus on verifying chassis model, engine power, gross vehicle weight, overall dimensions, and emission standard (China VI). For CLW5180GSSD6, for example, the gross vehicle weight is 18,000 kg, wheelbase is 4,500 mm, chassis is Dongfeng, and it is equipped with a China VI-compliant engine. 4. Compare Announcement Images: Cross-check the vehicle exterior images included in the official announcement against actual photos provided by the supplier to prevent discrepancies between advertised and delivered units. 5. Confirm Validity Period: Ensure the announcement batch remains valid—typically two years; expired batches require re-application. In the Wuhan case, the evaluation panel identified that the 'Dongfeng New Sewage Treatment Vehicle' offered by a certain supplier corresponded in its announcement number to a standard water tanker—not a specialized sewage treatment vehicle—thus disqualifying that proposal. III. Case of Fraudulent Announcement: How Procurement Entities 'Step Into Traps' The following is a real experience from a municipal sanitation department (name anonymized): In 2024, the department procured a batch of vacuum sewage trucks. A supplier claimed its product featured a 'Dongfeng chassis with complete MIIT announcement documentat
