Unlike base ocean freight, which is fixed per container or TEU at booking, the congestion surcharge is a variable fee that carriers invoice separately whenever a terminal or port is operating above normal capacity. It appears as its own line on the freight bill, distinct from the base rate and standard surcharges such as BAF (Bunker Adjustment Factor) or CAF (Currency Adjustment Factor). The amount follows the carrier's published tariff and may escalate in tiers if congestion is prolonged. The practical implication is straightforward: two identical 40-ft containers on the same trade lane can carry different total costs depending on terminal conditions at the time of processing. Not to be confused with detention charges, which accrue when a container stays outside the depot beyond its free-time window – irrespective of whether any congestion exists at the terminal.
