The annual inspection of vehicles with Guangdong-Hong Kong dual license plates is not a single procedure, but a compliance system that needs to be completed simultaneously in both mainland China and Hong Kong. If either side fails to meet the deadline, the vehicle may be intercepted at the border, or even face the risk of having its license plate revoked.

        　　Key Takeaways (Emphasis on SMEs and MSMEs)

        According to the new regulations in 2026, any omission in any step will lead to obstruction of customs clearance.

        Vehicle inspection in Hong Kong follows the principle of "local jurisdiction." Vehicles with Guangdong Z plates (Hong Kong vehicles) must complete their inspection at designated inspection centers in Hong Kong; vehicles with FV/FU plates (Mainland China vehicles) must complete their annual inspection at qualified inspection stations in Mainland China.

        Cross-border permit IC card renewal (core): This is the qualification certificate for vehicles to cross borders, and it is reviewed by the Traffic Management Bureau of the Guangdong Provincial Public Security Department. The permit card is usually valid for one year and needs to be renewed annually.

        Hong Kong and Macau Restricted Area Pass/Cross-border Qualification Verification: The restricted area pass is a transit permit issued by the Hong Kong Transport Department and needs to be renewed separately upon expiration.

        Consequences of overdue rating

        Short-term overdue: Port warning issued, cross-border passage prohibited.

        Overdue for 1-3 months: Permit card locked, quota frozen, vehicle cannot cross borders, cannot directly cross borders on the road, and an explanation of the situation plus a full set of documents is required for review;

        Overdue for 3-6 months: Quota frozen, review threshold significantly increased, quota directly cancelled if reasons are insufficient;

        Long-term overdue (more than 3 years): The license plate quota will be permanently cancelled and cannot be restored, meaning the license plate is completely invalid.

        　　Overdue remedial measures (in order of priority)

        Step 1: Pay all outstanding fines for traffic violations in both Mainland China and Hong Kong.

        Step 2: Complete the vehicle inspection. Arrange for the annual inspection in mainland China according to the vehicle's age requirements. The vehicle needs to return to Hong Kong for inspection and obtain a certificate of conformity. If the vehicle cannot return to Hong Kong from mainland China, submit a written explanation letter and proof of the vehicle's presence in mainland China to the Hong Kong Transport Department to apply for a license extension (with sufficient and reasonable grounds).

        Step 3: Complete the cross-border insurance to ensure a seamless policy transition.

        Step 4: Apply for an extension of the approval card (Mainland China). If the overdue period is long, it is recommended to apply in person at the window.

        Step 5: Hong Kong License Renewal (Transport Department) Submit vehicle inspection certificate, insurance, and registration documents to renew Hong Kong vehicle license plates and CRP restricted area permits;

        Step 6: After the port registration unlock permit card and Hong Kong license are renewed, go to customs and border inspection to update the registration, remove the customs clearance lock, and restore cross-border passage rights.

        　　In summary, the annual inspection of Guangdong-Hong Kong dual license plates is a systematic maintenance task that requires collaboration and advance planning between the two regions. Given the dynamic nature of policy adjustments, it is recommended to consult us or seek guidance from official channels before proceeding.
