A shipment can travel exactly on schedule across the ocean and still be delayed — not because of anything that happened at sea, but because of congestion at Chattogram port once it arrives. This is a separate variable from transit time and worth understanding on its own.
What Causes Port Congestion
Congestion typically builds when vessel arrivals cluster together, when there’s a shortage of berths or handling equipment, or during periods of unusually high import volume nationally. It can also follow disruptions elsewhere in the shipping network that bunch up arrivals.
What It Means for Your Shipment
During congestion, containers may wait longer to be unloaded from the vessel, and yard space for holding containers before clearance can also become tight. This can push your cargo closer to or past its free time, risking storage charges even though the delay wasn’t caused by your paperwork.

How to Reduce the Impact
- Have your import documentation ready before the vessel arrives, so clearance can start immediately
- Ask your forwarder for current port conditions rather than assuming normal timelines
- Build a buffer into your restocking plans if you know your route runs through Chattogram during a busy period
