The announcement is as follows:

1、 Starting from July 1, 2023, phase 6b of the national emission standard will be fully implemented nationwide, and the production, import, and sale of vehicles that do not meet phase 6b of the national emission standard will be prohibited. The production date shall be based on the manufacturing date of the motor vehicle certificate, and the electronic information of the certificate shall be uploaded before 0:00 on July 1, 2023; The import date shall be based on the arrival date indicated on the import certificate of the goods; The sales date shall be based on the date of the motor vehicle sales invoice.

2、 For some of the actual driving pollutant emission tests (i.e. RDE tests) that report results of "only monitoring" and other light vehicle models in China VI B, a six-month sales transition period will be granted, allowing sales until December 31, 2023.

3、 As the responsible entity for environmental production consistency management, automobile production and import enterprises should, in accordance with relevant regulations such as the Air Pollution Prevention and Control Law of the People's Republic of China, disclose vehicle emission inspection information and pollution control technology information before the vehicle leaves the factory or enters the country, to ensure that the actual produced and imported vehicles meet the requirements. The relevant certification agency shall issue a mandatory product certification certificate in accordance with the 6b stage of the National VI emission standard.

Knowledge expansion:

National VI is the sixth stage of the national emission standards for motor vehicle pollutants. The national VI emission standards have two stages, namely National VI Phase A and National VI Phase B. The National VI Phase A standards will be implemented on July 1, 2020, and the National VI Phase B standards will be implemented on July 1, 2023.

The standards for Phase A of National VI will be relatively lenient, while Phase B of National VI is the strictest emission standard in history:

The emission of carbon monoxide in Phase A of National VI shall not exceed 700mg/km, while Phase B of National VI requires 500mg/km;

For non methane hydrocarbons, the content required by National VI A should not exceed 68mg/km, while National VI B is 35mg/km;

The emission of nitrogen oxides is required by National VI A not to exceed 60mg/km, and National VI B not to exceed 35mg/km;

The emission of PM fine particles in China cannot exceed 4.5mg/km for country VI a and 3mg/km for country VI b.
