What is the emission standard for 2013 vehicles?

[Barbosa]

Vehicles manufactured after July 1, 2013 are generally compliant with China IV emission standards, as this was the deadline for China III vehicle registration. Nineteen regions including Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Urumqi, and Lanzhou strictly implemented the China IV standard from July 1, 2013. The nationwide implementation of China IV emission standards began on January 1, 2014. Here are some methods to check your vehicle's emission standard: 1. The simplest way is to check the environmental protection label on your vehicle - the standard is clearly marked on the back of the label. 2. Visit the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center to inquire. 3. Bring your vehicle registration certificate (original or copy) to the local vehicle management office for verification. 4. For new vehicles, you can check the vehicle's factory certificate of conformity, though typically this document is kept on file at the vehicle management office.
