What Year Are China IV Vehicles?
3 Answers
The implementation time of emission standards varies across different regions in the country, so it is not possible to determine which year China IV vehicles belong to. The following methods can be used to check a vehicle's emission standard: 1. The most direct way to check a vehicle's emission standard is to look at the environmental protection label on the front windshield of the vehicle, which has a clear mark on the back. 2. However, the environmental protection label has been canceled, and most vehicles no longer have this label. Nevertheless, the emission standard can still be checked on the vehicle's factory certificate or the environmental inspection qualification mark. Alternatively, you can log in to the 'Motor Vehicle Environmental Protection Website' to inquire about the emission standard.
I run an auto repair shop. The China 4 emission standard was implemented nationwide for gasoline vehicles in July 2011, while diesel vehicles followed half a year later in 2012. For vehicles with the manufacture year marked on the license plate tail number, those produced between 2013 and 2017 mostly comply with China 4. However, it's worth noting that some pre-registered vehicles obtained China 4 certification as early as late 2010. The most accurate way to verify during inspections is to check the color of the environmental label on the windshield – green background with white characters indicates a China 4 vehicle. Currently, some cities have started restricting China 4 vehicles from entering urban areas, so it's best to check local policies before purchasing a used car.
As a used car appraiser, when evaluating China IV vehicles, focus on the registration date: gasoline cars registered after July 2011 are definitely China IV compliant. However, be aware of regional implementation differences—for example, Beijing began enforcing the standard as early as December 2010. The most reliable method is to check the emission standard column on the vehicle conformity certificate. Currently, many used cars from 2011 to 2015 on the market are China IV compliant, though some luxury brands had models meeting the standard ahead of schedule as early as 2009. When purchasing such vehicles recently, consider the risk of relocation restrictions, especially if planning cross-province transfers.
