Boarding and rummaging procedures require shipping agents to notify authorities, assist officers, and enable detention of prohibited goods. Procedure mandates that designated Superintendents depute Preventive Officers as Boarding Officers for specified ports and anchorages; shipping agents must give advance notice, board with the Boarding Officer and Rummaging Team to assist without obstruction, and make logistical arrangements. Boarding Officers perform statutory duties under the Customs Act and manuals; prohibited, restricted or undeclared goods found during rummaging are detained or seized by Panchanama in the presence of two independent witnesses and the Master, with notification to the Superintendent Rummaging & Discipline.
