Definition & Explanation
The Congestion Surcharge (CSC) allows carriers to recover costs triggered by port or terminal bottlenecks—vessel waiting time outside the berth, reduced handling throughput, and disrupted sailing schedules. It can apply at the origin port, the destination port, or at transshipment hubs, depending on where the bottleneck occurs, and is typically quoted per container or per TEU. Unlike the Bunker Adjustment Factor (BAF), which tracks fuel price movements, the CSC reflects infrastructure constraints and the operational cost of waiting. Rates vary significantly by trade lane and current port conditions; shippers should monitor carrier tariff notices closely, as the surcharge can be introduced or revised on short notice.
