Transhipment procedure: authorised transit of export cargo via LCSs with ECTS sealing and bond-based safeguards for security and verification. Pilot procedure permits transhipment of export cargo from Bangladesh through specified LCSs to Kolkata Port/Air Cargo and by rail to Nhavasheva, requiring a Bill of Transshipment filed by the shipping line/airline or authorised representative, sealing of the conveyance with an ECTS seal (procured at carrier expense), and a Bond equal to twice the value of the goods. Original Bill retained at LCS, transference copy accompanies cargo to port/airport, and port officers verify ECTS seal integrity and upload trip and manifest details to the ECTS application to enable cancellation or crediting of the bond; unauthorized unsealing is to be reported for action.
