Which cities have implemented China 6 emission standards?

Provinces and cities implementing China 6 standards include: Hebei, Henan, Hainan, Chongqing, Anhui, Shaanxi, Sichuan, Chengdu, Hangzhou, Nanjing, Shandong, Shaanxi, and others. Below are introductions to China 6 standards and their implementation timeline: Introduction to China 6: China 6 refers to the implementation phase of motor vehicle exhaust emission testing standards. Additionally, there is a fuel standard. Fuel standards and vehicle emission standards are two completely different concepts, yet they are interdependent. The implementation of new fuel standards means that non-compliant fuels will be discontinued. China 6 standard release dates: The China 6 standards were issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine on December 23, 2016, and June 22, 2018, respectively. The "Limits and Measurement Methods for Emissions from Heavy-Duty Diesel Vehicles (China VI)" came into effect on July 1, 2019. The implementation of China 6 standards imposes stricter requirements on emissions such as carbon monoxide, nitrogen oxides, and hydrocarbons.

Recently, while helping a friend look for a used car, I noticed the implementation of China 6 standards. China 6 is divided into two phases, A and B, with the earliest adoption of China 6B starting in 2019 in Beijing, Shanghai, Guangzhou, Shenzhen, and Tianjin. The following year, the Jiangsu-Zhejiang-Shanghai region, known for its free shipping policies, also fully adopted it, covering the Pearl River Delta city clusters like Dongguan and Foshan. A special case is Henan province, which uniformly implemented the standards in 2021, but China 6A vehicles were given an additional six-month transition period. A reminder to everyone: when buying a car from another region, first check the local environmental protection website. I've seen cases where someone bought a China 5 car that couldn’t be registered in another region, resulting in a wasted trip.

Friends who just bought a new car last year can relate. All 31 provinces and municipalities in China have now implemented the China VI emission standards, but the rollout varies by region. For example, Shandong's 17 cities were divided into three batches for implementation, with Qingdao adopting the standards ahead of schedule in 2019. According to my research, major southwestern cities like Chengdu and Chongqing started in 2020, while mountainous areas may have delayed implementation by half a year. The timelines for heavy-duty diesel vehicles and light-duty vehicles also differ, so commercial vehicle buyers need to carefully check local official announcements for specific deadlines.

My cousin who just got his driver's license asked me about China VI emission standards. The implementation actually varies by vehicle type and region. For light passenger vehicles and sedans, major economic zones like Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta implemented it between 2019-2020, while provincial capitals like Zhengzhou and Taiyuan adopted it in 2021. Heavy-duty trucks transitioned later, with some western cities not switching until 2022. The key factor is the vehicle's production date - cars manufactured in 2018 might face restrictions in other provinces. It's best to call the local vehicle management office for verification.

According to 4S store salespeople, China's National VI emission standards have basically achieved full coverage across 340 prefecture-level cities nationwide. The key distinction lies between National VI A and B phases: Major cities like Beijing, Shanghai, Guangzhou, Shenzhen, and Hangzhou only recognize National VI B since 2023, where new National VI A vehicles can't be registered. Central and western regions still temporarily permit National VI A sales, with buffer periods lasting until year-end in cities like Lanzhou and Yinchuan. Parallel import car buyers should pay special attention as some port cities implement stricter registration requirements.

A seasoned transport driver told me the key points to watch are threefold: First, direct-controlled municipalities and separately listed cities implement the standards earliest; second, emission standards tighten year by year—Lüliang in Shanxi only adopted China VI-A last year; finally, it depends on the specific vehicle model, as light and heavy trucks are managed in phases across different cities. Places like Liaocheng and Heze in Shandong implemented the standards a year later than Jinan. When buying used vehicles, the registration location policy is more crucial than the vehicle's origin—a nuance many fail to grasp.
