Speaking of used cars may not be unfamiliar to you, many used cars still look very new, and the price is very low, many people are tempted, but most of them just look and do not really place orders. The reason for chasing after this is nothing more than the mixed use of cohabitation in the used car market. The use of vehicles varies greatly. Old drivers are easy to recruit, not to mention trucks that are not deep in the world. 
However, the introduction of a "second-hand, heavy truck appraisal and assessment specification" has given everyone a sure-footed pill - the used car market has finally been supervised!
On October 29th, the China Auto Circulation Association's group standard “Assessment and Evaluation Criteria for Used Medium-sized and Heavy-duty Trucks†was officially released at the 2016 China Commercial Vehicles Expo which is being held in Chongqing. The specification will start on March 1, 2017. Implementation. Its introduction marks the country’s more than 10 million commercial vehicle market, and it has the first specialized appraisal and evaluation specification for and applicable to medium-sized and heavy-duty second-hand commercial vehicles, which regulates market operations, establishes industry credit, and protects The legitimate rights and interests of consumers are of great significance. 
At the end of 2015, five domestic advanced enterprises in the commercial vehicle industry, including Beijing Futian Daimler Automotive Co., Ltd. and Shandong Huatong Used Car Information Technology Co., Ltd., took the lead in launching the project. The China Automobile Dealers Association initiated the project and launched the “Assessment and Evaluation Criteria for Used Commercial Vehiclesâ€. Group standard project. The project is divided into four separate parts: heavy-duty trucks, light and mini trucks, passenger cars and special vehicles.
The standard provides scientific assessment and evaluation procedures and evaluation methods. Its publication and implementation will help improve the overall technical level of second-hand commercial vehicle appraisal and assessment personnel; standardize the operating behavior of second-hand commercial vehicle assessment agencies and improve management standards. Accelerate the circulation of second-hand commercial vehicles; guide and promote the use of the secondary commercial vehicle market in a direction of normalization and health. 
Therefore, after the issuance of this standard, the China Automobile Dealers Association and the Commercial Vehicles Association will also launch a series of detailed implementation rules, organize relevant standards interpretation and training, ensure the smooth promotion and implementation of this standard across the country, and be the norm and health of the industry. Development made further efforts.
With the development of China's truck industry, the used car market will also become more and more mature. In fact, according to the home survey of trucks, the used car market in Shenzhen and other places is gaining momentum and even overwhelmed the new car market. Before China had no commercial second-hand car standard, the appraisers in the transaction could only learn from the used car evaluation criteria, which directly affected the trade of used cars. The promulgation of this standard has changed the problem of opaque information in the commercial vehicle used car market, and has played a positive role in the development of the used car market for commercial vehicles in China.
