Trade Single Window - What's New - Trade Single Window Phase 3 Services – System-to-System Interface

Trade Single Window (TSW) Phase 3 services will be rolled out in three batches starting in 2026, covering the following trade documents and cargo information:

1. Import and Export Declaration (TDEC);
2. Cargo information including Advance Cargo Information (Road and Air), Cargo Manifest and Cargo Report in respect of different transport modes; and
3. Applications for the Certificate of Origin (CO) and Permit for Dutiable Commodities (DCP).

The first batch of services is planned for launch in mid-2026, when the TSW system will replace the existing Road Cargo System (ROCARS) for the trade to submit electronic advance cargo information (Road). The second and third batches of services are targeted for launch in 2027, when the TSW system will replace the Government Electronic Trading Services (GETS) as well as the existing air cargo and sea cargo clearance systems of the Hong Kong Customs and Excise Department (C&ED), namely the Air Cargo Clearance System (ACCS) and Sea Cargo Support System (SCSS), enabling the trade to submit additional trade documents and cargo information covered under the TSW Phase 3.

For those who are interested in understanding more about the System-to-System Interface option, please contact the Single Window Project Management Office of the Commerce and Economic Development Bureau at 3525 1250, or email to sw@cedb.gov.hk for enquiries and relevant Implementation Instructions.
