Self-sealing export container procedure: reduced routine physical checks and one-in-five visual inspections permitted at Gateway Ports. Containers moved under the self-sealing procedure at Gateway Ports are to be exempted from routine opening; only one out of five self-sealed containers should be opened for visual inspection, and from each opened container a minimum of two packages and up to 5% of packages may be examined. The para 7 sampling percentage applies only to goods not under the self-sealing procedure, and conflicting Public Notices and Standing Orders must be amended.
