Which regions can National 4 vehicles be relocated to in 2020?
2 Answers
In 2020, National 4 vehicles can currently be relocated to all regions except for 15 cities in the three major areas of Beijing-Tianjin-Hebei, Jiangsu-Zhejiang-Shanghai, and the Yangtze River Delta. However, before relocating, it is advisable to consult the local vehicle management office to avoid any policy changes. National 4 refers to the fourth stage of China's national standards for motor vehicle pollutant emissions. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, these standards aim to control and reduce vehicle emissions below specified limits.
I remember in 2020 when I helped a friend with the relocation of a National IV standard vehicle, many places in the northwest could still accept them, such as the entire Qinghai province, Shizuishan in Ningxia, and Karamay in Xinjiang. In the southwest, Qujing and Wenshan in Yunnan, as well as Zunyi in Guizhou, also allowed entry, but it was necessary to avoid provincial capitals. It's important to note that border cities have stricter policies, like Ruili, which did not accept National IV vehicles. In the northeast, Shuangyashan and Hegang in Heilongjiang were still acceptable, but Harbin had long stopped allowing them. The details of implementation vary by each city's vehicle management office, so it's best to call two weeks in advance to confirm the required materials to avoid a wasted trip. Now the policies have tightened further, and places that could accept them before may now be prohibited.
