Which regions can National 4 vehicles be relocated to in 2020?

[DeThomas]

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.

As a seasoned veteran with over a decade of experience at the DMV, the relocation of National IV vehicles in 2020 depends on the specific province's emission thresholds. In Heilongjiang, only Harbin allows entry; in Jilin, all cities except Changchun and Songyuan permit relocation; Liaoning only accepts applications from third- and fourth-tier cities like Fushun and Tieling. In the northwest, Zhangye and Jiuquan in Gansu, as well as Altay in Xinjiang, accept these vehicles but require additional local environmental inspection reports. The southwest is relatively lenient, with all areas of Tibet and high-altitude cities like Baoshan in Yunnan being acceptable. The most challenging regions are the Pearl River Delta and Yangtze River Delta, where even small counties enforce strict restrictions—it's advisable to seek opportunities in central and western regions.

Last year, my cousin moved his National IV SUV from Shanghai to Hulunbuir in Inner Mongolia. In 2020, the regions that could accept such vehicles were mainly concentrated in less developed cities in central and western China. Coal-mining cities like Yuncheng and Datong in Shanxi, and Yulin in Shaanxi had relatively lenient policies; Baise and Hechi in Guangxi also accepted them, but Guilin and Liuzhou did not. Before moving the vehicle, it's essential to check the relocation standards published on the local ecological environment bureau's official website, as some cities may require the installation of an OBD detector. It's best to choose prefecture-level cities with a population of less than one million, as most large cities have completely banned National IV vehicles.

In 2020, areas where National IV emission standard vehicles could enter were mainly regions where National V standards hadn't been fully implemented. In Northeast China, only Chaoyang and Fuxin in northwestern Liaoning remained accessible; in Northwest China, the entire Qinghai province along with Hami and Turpan in Xinjiang still accepted them; Central China's Xiangyang and Shiyan in Hubei could still process registrations at that time. However, many locations set vehicle age restrictions, such as refusing entry to cars older than 8 years. If genuinely needing to proceed, prioritize cities with lower industrial output like Jingdezhen in Jiangxi province - tourism-oriented areas tend to have looser restrictions.

At that time, my neighbor's China IV standard pickup truck was successfully transferred to Yulin, Guangxi. In 2020, the areas that allowed such transfers were mainly concentrated in third- and fourth-tier cities. Places like Tongren in Guizhou and Zhaotong in Yunnan in the southwest could handle it; industrial cities in the northwest such as Jinchang in Gansu and Wuzhong in Ningxia also accepted these transfers. However, areas within the radiation circle of provincial capitals were mostly off-limits—for example, all cities within a two-hour drive of Chengdu were prohibited. Now, the process is definitely stricter. It's best not to gamble on policy loopholes; the safest bet is to call 12580 to connect with the local vehicle management office and ask directly.
