A port closure is declared when a port or terminal is shut to vessel traffic—whether for hours or weeks—following natural disasters, severe weather, industrial action, security incidents, or major infrastructure failures. No ships can enter or depart; cargo handling ceases entirely. For shipowners, the immediate consequences are demurrage costs and rerouting decisions; for freight forwarders and shippers, customs clearance and delivery timelines slip accordingly. The disruption rarely stays contained: warehousing backlogs build up, truck departures stall, and rail connections are left without cargo, creating a cascading effect across supply chains that can outlast the closure itself.
