How to Check Whether It's China 5 or China 6?
2 Answers
To check whether it's China 5 or China 6, you can use the following methods: 1. Vehicle manufacturing certificate; 2. Vehicle environmental protection standard list; 3. Check the vehicle conformity certificate. The difference between China 5 and China 6 lies in the carbon monoxide emission: China 5 emission is 1000mg; China 6 emission is 700mg. China 5 stands for the National Fifth Stage Emission Standard for Motor Vehicle Pollutants, while China 6 stands for the National Sixth Stage Emission Standard for Motor Vehicle Pollutants. Both China 5 and China 6 regulate the content of harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot.
The most straightforward method is to check the Vehicle Conformity Certificate or the Environmental Protection Information List, both of which are delivered with the car at the time of purchase. Last time I helped a friend inspect a car, I specifically checked this—on the third page of the Conformity Certificate, under the vehicle emission standards section, it clearly states whether it's China 5 or China 6. If the documents are lost, don’t worry. Nowadays, all cars have an oval-shaped yellow environmental label in the lower right corner of the windshield, which indicates "China VI" for China 6 or "China V" for China 5. Additionally, the nameplate on the door frame displays the vehicle model number. Entering this number into the public query platform of the Motor Vehicle Environmental Protection Website will give you the specific emission information in just five seconds. The production date can also serve as a reference—most cars produced after 2019 are generally China 6 compliant—but the most accurate method is still checking the certificate or the website.
