How to Identify China 5 and China 6 Emission Standards?
2 Answers
If it's a new car, you can check the vehicle's factory certificate or the environmental standard list. Below is relevant knowledge about identifying China 5 and China 6 standards: 1. Check the relevant content on the certificate: The vehicle's certificate contains many key pieces of information, including the emission standard, which will clearly indicate the national emission standard the vehicle complies with. For example, a China 5 vehicle will be labeled as "GB18352.5-2013 China V." Therefore, checking the certificate is a very effective method to determine whether the car you intend to purchase is China 5 or China 6. 2. Review the environmental information list included with the vehicle: When purchasing a car through official channels, the provided documentation will include an environmental information list. In the first section related to vehicle information, there will be an item for the emission stage, which will clearly and concisely indicate whether the model is China 5 or China 6. 3. Query through specialized websites: After identifying the model you intend to purchase, you can find specific vehicle identification numbers in the relevant documents, such as the engine number and chassis number. Then, by visiting the Motor Vehicle Environmental Protection Website and entering these numbers, you can query the vehicle's environmental information, including the emission standard it complies with. 4. Carefully verify the vehicle conformity certificate: During the vehicle delivery process, the dealer will provide the vehicle's conformity certificate. You can carefully check the relevant content, which includes an item named "Exhaust Emissions," detailing the specific national standard number referenced during certification. The standard number and corresponding year will indicate whether it is China 5 or China 6.
I used to have a headache over this issue too, until I found the most reliable method is to check the vehicle documentation. When we buy a car, we all receive an environmental information list that comes with the vehicle - this document is as clear as an ID card, explicitly stating whether it's China 5 or China 6 standard. If you can't find the paper document, just take out your phone, log into the Motor Vehicle Environmental Protection Website, enter the 17-digit VIN code located at the bottom left of the windshield along with the last six digits of the engine number, and you'll immediately find the registered emission standard. When I helped a friend check a used car last time, I discovered most vehicles manufactured after July 2019 had already upgraded to China 6 standard. But you still need to be cautious - some manufacturers might produce China 6 compliant vehicles earlier, so checking the specific model is safest. For example, China 6b compliant vehicles will have special markings near the exhaust pipe.
