Container Freight Station procedures: permit, seal and register rules govern movement, custody and supervised stuffing of import/export containers. Procedural framework for the CONCOR Container Freight Station at Vallarpadam prescribes authorization to handle FCL and LCL import/export cargo, mandatory bond and bank guarantee verification, and detailed requirements for transshipment/ movement permits with Space Availability Certificates. Gate officers must verify container and seal numbers and endorse out-times; containers must meet prescribed transit windows, seal tampering must be recorded and reported, and Customs bottle seals applied when required. The CFS operator must maintain comprehensive registers and weekly statements, supervise supervised destuffing and stuffing under Customs officers, ensure segregation of detained/hazardous cargo, and permit removal of goods only after Customs out of charge.
