How to Identify the National Emission Standard of a Car?

[IsabelaLee]

Methods to determine the national emission standard of a car are as follows: 1. Check the vehicle's environmental protection label: There are clear markings on the back of the label. 2. Log in to the public inquiry platform of the Motor Vehicle Environmental Protection Website: Enter the vehicle's VIN (Vehicle Identification Number) and the last 6 digits of the engine number to query the vehicle information. 3. Based on the vehicle's manufacturing year: Most cars manufactured after 2008 are National IV; cars registered in 2007 may be National III or National IV; cars manufactured before 2007 are generally below National IV, i.e., National III or National II; cars manufactured before 2005 are mostly National II. 4. Take the motor vehicle registration certificate (original or copy) to the vehicle management office for inquiry.
