Is 50% Window Tint Legal in China After the 2026 Policy Reforms?

No. China’s traffic safety laws prohibit window tinting exceeding 30% light transmittance for front side windows, making 50% illegal nationwide. Local enforcement varies, but national standards enforced by the Ministry of Public Security (MPS) and local traffic authorities invalidate any aftermarket tint surpassing this threshold. Non-compliance risks fines up to ¥200 and mandatory removal.


Key Regulations for 50% Window Tint in China

  • National Standard GB 7258-2017: Mandates minimum 70% light transmittance for front side windows, rendering 50% illegal. Rear windows may allow up to 50% tint only if the vehicle has side mirrors on both sides.
  • Local Enforcement Variations: Cities like Beijing and Shanghai impose stricter checks, with police using light transmittance meters during roadside inspections. Guangdong’s 2024 pilot program allows digital verification via traffic apps, accelerating penalty issuance.
  • 2026 Compliance Shifts: The MPS plans nationwide adoption of AI-powered tint detection systems in traffic monitoring, eliminating ambiguity in enforcement. Vehicles with factory-tinted windows must display compliance certificates to avoid penalties.
