No, 35% window tint is illegal in China. The Technical Supervision Law of the People’s Republic of China and GB 9656-2016 mandate front-side windows must permit ≥70% light transmittance. Local traffic authorities, including provincial Public Security Traffic Management Bureaus, enforce this uniformly. Non-compliance risks fines up to ¥200 and mandatory removal.
Key Regulations for 35% Window Tint in China
- Front-side windows: Must achieve ≥70% light transmittance (≤30% tint). 35% tint violates this threshold.
- Rear-side/rear windows: Permitted up to 50% tint, but only if the vehicle has dual side mirrors (GB 9656-2016, Section 5.3).
- Enforcement: Local Public Security Traffic Management Bureaus conduct roadside checks using portable light transmittance meters. Vehicles failing inspection face immediate penalties.
Note: Shanghai and Beijing traffic regulations impose stricter enforcement, with 2026 pilot programs testing AI-based tint detection at major checkpoints. Aftermarket tint films must comply with GA/T 1524-2018 certification standards.
