How to Determine Whether a Vehicle is China 5 or China 6 Standard?
2 Answers
You can identify whether a vehicle meets China 5 or China 6 standards by checking the vehicle's factory certificate, environmental protection standard list, or vehicle conformity certificate. Here is additional information: 1. Environmental Information Onboard List: As the name suggests, this document details the vehicle's environmental impact and clearly indicates the exhaust emission standard, whether it's China 5 or China 6. By reviewing this list, you can definitively determine the vehicle's emission stage. 2. Vehicle Conformity Certificate: This certificate explicitly states the vehicle's emission standard. Although it may not directly label the vehicle as China 5 or China 6, the emission standard code (e.g., GB18352.5 for China 5) allows for clear identification.
When I bought my car before, I specifically researched how to distinguish between China 5 and China 6 emission standards. The most direct method is to open the driver's door and look for the vehicle identification plate on the B-pillar, which clearly indicates the emission standard. If the plate is blurry and hard to read, there's a handy trick—open the hood and locate the environmental information label in the engine compartment. It will specify GB18352.5 for China 5 or GB18352.6 for China 6. Nowadays, you can also check via the Traffic Management 12123 app by entering the VIN, and the system will display the emission level. I recommend also reviewing the vehicle conformity certificate, which is delivered with the car at purchase—the third page contains a detailed description of the emission standard. However, note that implementation times vary by region. For example, vehicles manufactured after 2019 in the Pearl River Delta region are mostly China 6 compliant.
