How to Check China 5 and China 6 Emission Standards?
2 Answers
The China 5 emission standard is marked with the Roman numeral "V", while the China 6 emission standard is marked with "Ⅵ". When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes the model, color, emission standard, engine number, and chassis number. For used cars, you can check the emission standard by searching the vehicle model on the environmental protection website. Relevant information about vehicle emission standards is as follows: 1. Introduction: Vehicle emission standards regulate the content of harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) emitted from vehicle exhaust. 2. Implementation: Starting from January 1, 2004, Beijing upgraded the vehicle emission standards from Euro I to Euro II, and by 2008, officially implemented the Euro III standard.
I'm always into cars and have been driving for almost 20 years, so I know how to check China 5 and China 6 emission standards. The easiest way is to look at the environmental label in the lower left corner of the windshield—it's a small sticker that clearly states whether it's China 5 or China 6. If it's a newly purchased car, it's usually China 6. Alternatively, check your vehicle registration certificate; there's an emissions standard section on the registration page with the exact number. If the car was manufactured after 2019, it's most likely China 6, but be aware that some older cars might have had parts replaced—check the VIN (Vehicle Identification Number) carefully. You can search official databases online or use a car app to scan and verify. Don’t just go by appearances—this standard greatly affects urban driving restrictions, especially in major second-tier cities where China 6 is more favorable and easier for transfers. My neighbor learned this the hard way—he bought a China 5 car and couldn’t drive it in restricted zones, wasting a lot of effort. If you’re still unsure, ask a dealership or mechanic—they’re the experts.
