C&ED further extended the facilitation under the Intermodal Transhipment Facilitation Scheme (ITFS) by launching the Single E-lock Scheme (SELS) together with the Mainland Customs on 28 March 2016. Under the SELS, ITFS is interconnected with the Speedy Customs Clearance System(SCC System) of the Mainland Customs to build a “green lane” for facilitating logistics flow through seamless clearance service. One single e-lock and the technology of GPS as accredited by both Customs authorities are applied under the SELS on the principle of “Across the Boundary with One Single E-lock under Separate Monitoring” and hence duplicate inspection on the same shipment by both Customs authorities at the boundary would be reduced, which helps to streamline the clearance process and expedite the flow of transhipment cargoes.

Participation in the SELS is voluntary. Shippers or carriers who wish to join the SELS are required to register with the ITFS of C&ED and the SCC System of the Mainland Customs and install the e-lock and GPS equipment accredited by both Customs authorities on their vehicles.

The SELS was awarded the “Meritorious Award of the Departmental Service Enhancement Award” (Large Department category) in the “Civil Service Outstanding Service Award Scheme 2017” organized by Civil Service Bureau.

Single E-Lock and GPS Equipment

In addition to the operation of mechanical lock, the multiple flow control processes of e-lock is a distinctive feature that enables separate monitoring of Customs authorities in absolute integrity yet independent from each other so as to ensure seamless and secured monitoring when the transhipment cargo is conveyed across the boundary. Taking an example of Air-Land northbound transshipment mode, the transshipment cargoes arriving Hong Kong by air will be loaded to a cross-boundary vehicle after Customs clearance. An e-lock affixed to the vehicle will be automatically activated and GPS equipment will be used for tracking the movement of the vehicle to ensure the security of the cargoes during the journey within the Hong Kong territory. If no irregularities are detected during the journey, the e-lock will be automatically deactivated at the exit point. The e-lock will be automatically activated again after passing through the entry point of Mainland China. Upon arrival at the clearance point of the Mainland under the SELS, the e-lock will be deactivated.

C&ED welcomes all shippers or carriers to join the SELS. Prior registration of participating vehicles with Hong Kong and Mainland Customs authorities is necessary. The vehicles concerned should be equipped with e-lock and GPS accredited by both Customs authorities. Vehicles registered under the SELS are also subject to inspection by C&ED.
