Port terminal operator responsibility: containers with pre gate approval must not be shut out; re export arranged without extra cost. Port terminal operators must ensure containers that enter the Parking Plaza within prescribed timelines and receive pre gate approval in the Terminal Operating System are not shut out unless the trailer fails to enter the terminal within four hours of pre gate approval and all other formalities are not complied with. Exporters must plan to meet cut off times, and if a compliant consignment is shut out, terminal operators and shipping lines must arrange its export at the earliest opportunity without charging the exporter additional costs.
