Customs Container Freight Station procedures govern custody, sealing, permitted movement and reporting obligations for containerized cargo. Procedures require CPCFS to act as custodian within the Customs area, segregate FCL/LCL and special cargo, maintain bonds and detailed registers, and obtain serially numbered triplicate/transshipment permits with space availability certificates for movement from notified Customs areas; gate officers must verify container and seal numbers, inspect seals on arrival, record and report tamper, seal containers with customs bottle seals during interim custody, and follow prescribed transit times with explanations and condonation procedures for delays, with weekly and monthly reconciliation and reporting obligations to Customs.
