Check the vehicle's factory certificate or vehicle conformity certificate. Symbol markings: The symbols for China 1 to China 6 standards are I, II, III, IV, V, and VI respectively. China first introduced the China 1 emission standard on July 1, 2000. As it was based on European emission standards and aligned with international norms, Roman numerals were adopted for the China 1 to China 6 markings. New emission standards have been introduced every few years since then. China VI standard: The "China VI standard" is divided into two phases: "China VI a" and "China VI b", with nationwide implementation planned for July 1, 2020 and July 1, 2023 respectively. However, the China VI standard is extremely stringent, far exceeding Europe's Euro 6 and America's Tier 3 standards, making it one of the strictest emission standards globally. The implementation period for China VI standards will also be longer.
