National VI is the national Phase VI emission standard for motor vehicle pollutants. The National VI emission standard has two stages, namely Phase VI a and Phase VI b. Phase VI a standard will be implemented on July 1, 2020, while Phase VI b standard will be implemented on July 1, 2023.

Phase VI a standards will be less stringent. Phase VI b standards are the most stringent emission standards in history:

Country VI a stage requires carbon monoxide emissions cannot exceed 700mg/km, country VI b requires 500mg/km;

For non-methane hydrocarbons, the content of sexA should not exceed 68mg/km, while sexB is 35mg/km.

The emission of nitrogen oxides in country VI a shall not exceed 60mg/km, and Country VI b shall not exceed 35mg/km;

The emission of PM fine particulate matter should not exceed 4.5mg/km in Country 6A and 3mg/km in country 6A.
