[LucasDella]

The implementation date of the China VI-b standard is July 1, 2023. Here is some information about the China VI standard: 1. Introduction: The implementation of the China VI emission standard will be divided into two phases, "China VI-A" and "China VI-B," corresponding to July 1, 2020, and July 1, 2023, respectively. China VI-A can be seen as a transitional phase from China V to China VI. Some provinces and cities will implement the China VI emission standard ahead of schedule, with specific dates varying. 2. Regulations: After the implementation of the China VI emission standard, all vehicles sold and registered must meet the requirements of the China VI emission standard. Vehicles below the emission standard will be prohibited from being sold, registered, or transferred. China IV and China V emission vehicles can only be scrapped or relocated to regions where the China VI standard has not yet been implemented. 3. Legal provisions: Article 4, Clause 15 of the "Three-Year Action Plan for Winning the Blue Sky Defense War" issued by the State Council clearly stipulates that starting from July 1, 2019, key regions, the Pearl River Delta region, and the Chengdu-Chongqing region will implement the China VI emission standard ahead of schedule.
