How to Determine Whether a Car is China 5 or China 6 Standard?
2 Answers
To determine whether a car meets China 5 or China 6 emission standards, you can: 1. Check the vehicle's factory certificate; 2. Refer to the vehicle's environmental standard list; 3. Examine the vehicle conformity certificate. The differences between China 5 and China 6 standards are: 1. Different carbon monoxide emissions: China 5 allows 1000 mg while China 6 permits 700 mg. 2. Different emission limits: China 5's limit is 0.0045 g per kilometer whereas China 6's limit is 0.25 g per kilometer. China 5, officially named 'National Fifth Stage Motor Vehicle Pollutant Emission Standard', and China 6, 'National Sixth Stage Motor Vehicle Pollutant Emission Standard', both regulate the permissible levels of harmful emissions from vehicles including carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot.
Determining whether a car meets China 5 or China 6 emission standards is quite simple, mainly relying on everyday tricks to verify. There's usually a metal plate on the side of the door that directly states the emission standard number, such as GB18352.5 for China 5 or GB18352.6 for China 6. If the plate is too old to read clearly, I can go online and enter the Vehicle Identification Number (VIN) to check, as many car websites or mini-programs now offer free query tools. When buying a car, remember to check the registration certificate or environmental compliance list, which clearly states the standard. As someone who drives frequently, I also pay attention to the vehicle's manufacturing date—most China 5 cars were produced before 2017, while China 6 gradually replaced them after 2019. This distinction is quite important, especially in restricted zones where it affects driving permissions, and it also significantly impacts used car prices. Regular maintenance and early detection of emission issues can save a lot of trouble, especially as environmental requirements continue to tighten.
