# Port detention

> Unlike demurrage, which ties to the vessel, port detention applies to the container itself after discharge.

Unlike demurrage, which ties to the vessel, port detention applies to the container itself after discharge. When an import container sits at the terminal beyond the contractual free time period, the terminal operator or shipping line imposes daily detention charges. Common causes include delayed inland transport, pending customs clearance, or documentation issues. Free time allocations vary by carrier and port; once exceeded, charges accumulate daily and can escalate quickly at congested terminals. Freight forwarders and importers track detention deadlines closely to avoid unexpected costs.
