The first batch of Phase 3 services of the Trade Single Window (TSW) will be launched next Friday (May 1), replacing Road Cargo System (ROCARS) for the submission and bundling of advance cargo information (road) by the trade. User data of the existing ROCARS will be automatically migrated to the TSW system. Users are not required to re-register and only need to log in with their existing accounts to use the TSW services seamlessly.
      
     ROCARS will cease operation from midnight on May 1 to facilitate the system cutover work, and the TSW system is expected to launch in the early morning of the same day. During the system cutover period, cargo clearance services at land boundary control points will remain normal. Hong Kong Customs reminds the trade to plan ahead for the submission of advance cargo information (road) and the completion of the relevant bundling arrangements well in advance, so as to ensure the smooth flow of cross-boundary transportation during the system cutover period.
      
     Hong Kong Customs will continue to maintain close liaison with the trade to facilitate the smooth transition to the Phase 3 services of the TSW. For enquiries, please contact the Office of Trade Single Window Operation of Hong Kong Customs at 2117 3348 or by email to enquiry@tradesinglewindow.hk.
