What is the emission standard for cars from 2005?

[MacHenry]

2005 vehicles mostly comply with National II or National III emission standards, with most sedans, SUVs, and MPVs being National III. Methods to check a car's emission standard: 1. Environmental Label: The simplest way is to look at the vehicle's environmental label, which clearly indicates the standard on the back. 2. Vehicle Emission Supervision Website: Visit the official website of the Vehicle Emission Supervision Center to check. 3. Vehicle Management Office: Bring the vehicle registration certificate (original or copy) to the local vehicle management office for inquiry. 4. Factory Certificate: Check the vehicle's factory certificate, but since it is usually kept by the vehicle management office, it's advisable to make a copy when purchasing the car for future reference. 5. Rough Estimation Based on Registration Year: a. Most cars registered after 2008 are National IV. b. Cars registered in 2007 may be National III or National IV. c. Cars registered before 2007 are mostly below National IV, i.e., National II or National III. d. Cars registered before 2005 are mostly National II.
