When will the China VI policy be implemented?

[DelValeria]

The China VI standard will be officially implemented on July 1, 2023. The China VI standard is divided into two phases, a and b. Starting from July 1, 2019 at the earliest, all light-duty vehicles sold and registered must comply with China VI. The requirements for the two phases are as follows: 1. Phase a requirement: By July 1, 2023 at the latest, all light-duty vehicles sold and registered must comply with China VI. 2. Phase b limit requirement: This means that China VI a can only be considered a transitional phase, while China VI b is the true China VI phase. Note: Currently, some regions have implemented the China VI emission standard ahead of schedule. For example, Guangzhou implemented the China VI emission standard for light-duty gasoline and diesel vehicles starting from March 1, 2019; Shenzhen required light-duty diesel vehicles to comply with the China VI standard from July 1, 2018, and light-duty gasoline vehicles to comply with the China VI standard from July 1, 2019.

I remember vividly that the China 6 emission standards were implemented in phases. The first batch of cities adopted China 6a as early as July 2019, with key regions like Beijing, Shanghai, and Guangzhou skipping the transition period entirely. Nationwide mandatory enforcement of China 6a started in July 2020, and by this July, the entire country had upgraded to the stricter China 6b standard. People used to ask me whether they could still buy China 5 used cars—now it really depends on the registration policies of the destination city. The implementation pace varies significantly across regions, so it's best to check the latest notices from the local vehicle management office before purchasing. Don't just look at the manufacturing date, as many automakers switched production lines six months or more in advance.

I only took a closer look at the timeline recently when helping a friend shop for a car. Nationwide, there were actually two phases of implementation: in July 2020, it was the China 6a standard, mainly limiting carbon monoxide emissions. The full switch to China 6b this July is the real strict phase, even capping particulate emissions tightly. In reality, cities like Beijing, Shanghai, Guangzhou, and Shenzhen implemented China 6b three years ago, two years ahead of the national schedule. Many 4S stores were clearing out old models last year, so buying a new car now basically defaults to China 6b. When trading in an old car, be careful—cross-province transfers for China 5 vehicles are quite troublesome now.

The China VI emission standards have been in the works for many years. I remember it was first piloted in key regions in 2019, with nationwide implementation starting mid-2020 in two phases: first the transitional China VI-A, now upgraded to China VI-B. The crucial point is some provinces implemented stricter timelines than central documents required - like Zhejiang enforcing China VI-B as early as 2021. These regional differences directly impact used car markets. In our car owners' group, someone bought an out-of-province China V vehicle last year, only to find local transfer registration prohibited this year, now facing tens of thousands in losses.

From an automaker's perspective, this policy has been quite demanding. OEMs started preparing for technical upgrades as early as 2018, such as installing GPF (Gasoline Particulate Filters). Implementation was regional: Beijing-Tianjin-Hebei and Fenwei Plain regions pioneered the adoption in 2019, followed by nationwide China 6a coverage in 2020, with full transition to China 6b achieved this July. Here's a lesser-known fact - light-duty vehicles actually implemented the standards earlier than heavy-duty vehicles. When purchasing pickups or light buses now, be aware that some diesel models haven't yet caught up with the emission requirements.

Last time I helped my neighbor aunt sell her car, I finally understood this issue. The aunt's National 5 standard car was bought in 2020, and this year when she wanted to trade it in, she found out that neighboring provinces don't accept this type of vehicle anymore. The policy time gap is really tricky: some regions implemented National 6b as early as 2019, while others delayed until July this year. Nationally, National 6a was uniformly implemented in July 2020, and National 6b is mandatory this year, but 4S stores usually clear their inventory half a year in advance. So when buying a new car, check the environmental compliance documents that come with the vehicle, and don't trust the salesperson's verbal promises.
