How to Determine if a Vehicle Meets China 6 Emission Standards
2 Answers
Here are the methods to check whether a vehicle complies with China 6 emission standards: 1. The simplest way is to look at the vehicle's environmental protection label, where the "Emission Standard" section will indicate the level (e.g., China 4, China 5, etc.). However, the environmental protection label has been abolished, meaning current vehicles no longer carry this label. 2. For new vehicles, you can check the vehicle's factory certificate or conformity certificate. You will need to enter the VIN (Vehicle Identification Number) and the last 6 digits of the engine number. Additional information: 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. Since it was modeled after European emission standards to align with international norms, Roman numerals were adopted for the China 1 to China 6 labels. New emission standards have been introduced every few years since then.
To determine if a car meets China VI emission standards, I’ve been driving for almost ten years and encountered this issue many times. The most straightforward method is to check the vehicle’s nameplate or the label in the engine compartment—if it says “China VI” or “CN6,” you’re good to go. Don’t forget that the purchase invoice or compliance certificate for a new car will specify the emission standard. For used cars, request the vehicle registration certificate and check the emissions section, or enter the VIN on the environmental protection bureau’s official website using the license plate number for verification. Once, I almost bought the wrong car because I forgot to check, but later solved it by scanning with a mobile app like "Traffic Management 12123." China VI-compliant cars offer great benefits—they can enter restricted zones, are more fuel-efficient, and are environmentally friendly. If you’ve lost the documents, just visit a 4S shop or repair shop and ask a technician to read the OBD data via a diagnostic cable. In short, don’t rely on guesswork—take action and verify it properly.
