How to Determine if a Car is China IV or China V Standard?

[Carson]

Methods to identify whether a car meets China IV or China V emission standards: 1. Check the environmental protection label issued during vehicle inspection. A compliance sticker is provided upon passing the inspection, which should be affixed to the upper right corner of the windshield. The number of stars on the label indicates the emission standard - for example, 4 stars represent China IV. 2. Visit the official website of the local traffic management bureau to query the vehicle's emission standard. 3. The Motor Vehicle Environmental Protection Website can also verify emission standards by entering the car's brand and model. Automobile emission standards regulate the permissible levels of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter (PM) in exhaust emissions.

I've encountered this issue several times. The simplest and most straightforward method is to check the vehicle registration certificate, that green booklet. Turn to the page with vehicle information, and the emission standard is clearly stated. If you don't have the green booklet on hand, look for the nameplate on the co-pilot door frame, which contains the VIN and engine model. Input these two numbers into the motor vehicle environmental protection inquiry platform, and the result will pop up immediately. If you find it troublesome, you can directly check the environmental information section on the vehicle conformity certificate or the certificate of compliance. I remember helping a friend inspect a used car last year and found that most vehicles produced after 2016 are at least China V standard, while most from 2011 to 2015 are China IV standard. This timeline can also serve as a reference. The key point is that emission standards affect vehicle transfer and traffic restrictions, so don't take them lightly.

Just helped my cousin check his car last week. There are mainly four channels: first choice is the Motor Vehicle Environmental Protection Website, enter the last six digits of the VIN and engine number, official data is the most reliable; second is to check the third page of the big green book, the emission standard column is clearly written; then look at the environmental protection vehicle list that came with the car when it was new, black and white won't be wrong; finally, check the manufacturing date label on the door B-pillar, cars manufactured after July 2017 are basically China V. A reminder, implementation times vary by city, like Beijing and Shanghai implemented China V in 2016, while third and fourth-tier cities might be later. Recently, a lot of people are checking emissions, mainly because China IV cars are not allowed to transfer ownership in many places.

I know this like the back of my hand. First, check the 17-digit VIN at the bottom left corner of the windshield - wipe off any dust if needed. Then locate the engine number, usually under the hood. Open your phone and search for the 'Motor Vehicle Environmental Protection Inquiry' official website, enter these two sets of numbers, and it'll immediately show whether it's China IV or China V standard. If you're not internet-savvy, you can also check the vehicle records at the DMV. Additionally, look for the yellow environmental label on the car - though new cars don't get them anymore, older vehicles might still have them on the windshield. Emission standards make a huge difference: China V vehicles can legally operate several years longer than China IV, and the used car price gap can be 3,000-5,000 yuan.

Checking emission standards involves three steps: First, locate the vehicle's ID, which is the VIN (alphanumeric combination) under the windshield. Second, note down the last six digits of the engine number. Third, visit the motor vehicle environmental protection inquiry page on the Ministry of Ecology and Environment's official website and enter these two numbers. If no results are found, it may indicate that the vehicle is an early model, and you'll need to check the national standard code marked at the bottom of the original vehicle compliance certificate. Another straightforward method is to directly call the manufacturer's customer service, provide the VIN, and inquire—they have records in their system. The China V standard is significantly stricter than China IV, primarily differing in nitrogen oxide emissions, with the new standard reducing pollutants by 25%.

The most reliable way to check emission standards follows three steps: First, check the green vehicle registration certificate—the emission standard is listed on the second page under vehicle parameters. Next, locate the VIN at the bottom left of the windshield, enter it along with the last six digits of the engine number into the environmental protection website. Lastly, check the manufacturing date label—most cars produced after 2017 meet China 5 standards. I keep the environmental website bookmarked on my phone, and friends often ask me to help check when buying cars. Nowadays, WeChat mini-programs can also verify emissions—just snap and upload the vehicle license. Emission standards update rapidly; rumor has it China 6B will take effect this July, likely causing China 5 cars' resale value to drop.
