"Now we have imbedded the software on the crane. When the crane lifts a container, its information such as the number of the container, the weight and the situation of balance, will be collected and uploaded to Customs' platform. When the information has been verified, the train can be released, reducing one process of loading and unloading, and transporting the containers between different yards for inspection. Now the operation time to inspect one container is about one hour," he said.

"In addition, with close cooperation with the railway department, freight yard and the Customs, railway tracks are built in the area under Customs supervision, trains can be checked released and departed once the inspection is completed, greatly reducing the time for Customs clearance," he said.
