Drive-through container scanner procedure defines check-in, scanning, image review, seal verification, and scan-result issuance. Operationalization of a drive-through container scanner prescribes the procedure for scanning containers selected under the Container Selection Module and Bill of Entry linkage. The workflow covers check-in, control-room verification, scanning at the prescribed speed, holding-area procedures, image analysis, escalation to a supervisory officer where required, seal verification, and issuance of the scan result at the check-out cabin. If scanning is incomplete because of vehicle speed, the container is to be recalled for re-scanning, and officers are required to follow the stated standing instructions.
