Does Window Tinting Affect Vehicle Registration for 2021 New Cars?

[OElliana]

2021 new car window tinting affects vehicle registration. According to GB7258-2004 "Safety Technical Conditions for Motor Vehicles Operating on Roads" implemented in 2004, the driver's compartment must ensure forward and side visibility for the driver. The visible light transmittance of the windshield and other glass areas in the driver's line of sight must not be less than 70%. Mirror-reflective sunshade films are prohibited on all window glass. Do not roll windows up/down after tinting: After window tinting, avoid rolling windows up/down for one week. In most cases, automotive window film requires 5-7 days to fully adhere to the glass. During this period, minimize window operation to prevent displacement of the not-yet-fully-bonded film. Do not wipe: After window tinting, avoid wiping for one week. Newly applied film may develop fogging or haze - a normal phenomenon during the curing process. Such conditions appearing within one week to half a month are normal. Simply wait for the haze to disappear naturally; never attempt to wipe it. Avoid sharp objects: After window tinting, never use sharp or coarse tools to scrape the film. If accidentally scraped with sharp/hard objects, the film's light transmittance will be significantly compromised.

As someone who often helps friends with car issues, I want to remind everyone that applying window tint to a 2021 new car can indeed affect the license plate registration process. During vehicle inspection for registration, Chinese regulations require that the light transmittance of the front windshield and front side windows must exceed 70%. If you apply dark or low-transmittance tint film beforehand, insufficient light penetration may cause the inspection to fail. I know a car owner who applied tint too early and had to remove and reapply it, wasting 500 yuan unnecessarily. My advice is to wait until after obtaining the license plate before applying tint, choosing a high-transmittance film to avoid hassle while still providing sun protection for your skin. Don't rush with your new car - be patient to save yourself trouble. Applying tint after passing the inspection also ensures no issues during future annual inspections.

I was so excited when I bought my new 2021 car that I wanted to get it tinted immediately to make it look cooler. However, the experienced salesperson at the 4S store advised me to wait until after getting the license plate. They explained that the light transmittance inspection during new vehicle registration is very strict—anything below 70% would cause issues. I almost made that mistake myself. Later, I obediently waited until the plate was registered before getting the tint done. Now my car runs smoothly without any rework hassles. While window tinting offers many benefits like sun protection and heat insulation, regulations are non-negotiable. New car owners shouldn’t rush—consult your local DMV to confirm specific requirements, as standards may vary by region. Safety first is always the right approach. Getting the tint after registration is the smarter move.

Having repaired cars for decades, I've seen many cases where improper window tinting on new cars indeed affects license plate registration and inspection. The regulations require the front windshield to have a light transmittance of over 70%. Dark films with poor light transmission often fail inspection. I recommend car owners choose high-transmittance films or delay tinting until after completing the registration process. I've encountered several clients who had to remove their films at a loss. Professional tools are needed to accurately measure light transmittance to avoid misjudgment—saving both money and time while prioritizing safety. The choice of film material also matters; a properly applied quality film can last over 5 years without issues. Newcomers should consult more before making decisions.
