Port Congestion Surcharge Estimator
Total congestion and peak-season surcharges across a multi-container booking before the carrier does.
Congestion (PCS) and peak-season (PSS) surcharges are announced per trade lane with effective dates — they apply by sailing date, which is the detail to audit.
Sources & references
- Carrier surcharge notices/advisories (per trade lane)
- Service contract surcharge clauses (FMC-filed contracts, US trades)
Demurrage, detention and storage tariffs are set by each carrier, terminal and contract and change frequently. The preloaded figures are editable industry-typical examples, not quotes — always verify against the current published tariff or your service contract before paying or disputing an invoice.
Congestion and peak-season surcharges are the freight world's weather: announced per lane with two-to-four weeks' notice, layered on top of base rates, and quietly responsible for invoices that don't match quotes. A PCS prices a congested port's slower vessel turns; a PSS prices seasonal demand. Both bill per container, so multi-box bookings multiply the surprise.
About Port Congestion Surcharge Estimator
Enter your box count and the announced per-container amounts (carriers publish surcharge notices on their sites and via advisories — your forwarder forwards them, ideally before they apply). The calculator totals the stack per booking, which is the number to reconcile against the rated invoice line by line. The audit angle: surcharges apply by effective date against your sailing (sometimes receipt) date — a PSS announced for July 1 sailings doesn't belong on a June 28 departure. Mis-applied effective dates are among the most recovered surcharge disputes, and they're found only by shippers who kept the original announcement.

Frequently asked questions
What triggers a port congestion surcharge?+
Sustained vessel queueing or terminal slowdowns that stretch port stays — strikes, weather seasons, demand surges. Carriers announce a per-container PCS for affected lanes with an effective date and (sometimes) a sunset. It compensates the carrier's slower asset turns; whether it persists after the queue clears is exactly what shippers should police.
Are surcharges negotiable or fixed?+
Spot shippers mostly pay as announced; contract shippers negotiate — many service contracts cap, fix or exclude certain surcharges, and 'all-in' rates exist precisely to kill the stack. If your contract is silent on PCS/PSS, it's a renewal agenda item: surcharge exposure is a contract term you didn't set.
How do I verify a surcharge was validly applied?+
Three checks: the announcement exists for your lane (keep carrier advisories), the effective date covers your sailing date, and the amount matches the notice. Invoices fail the date check more than any other — quote the original advisory back with the vessel's departure date and the line item tends to vanish.
Do surcharges apply per container or per bill of lading?+
PCS and PSS are per container (per TEU or per box depending on the notice — read which). Documentation-type fees apply per B/L. A three-box booking with a $250 PSS 'per unit' owes $750, not $250; the per-unit ambiguity in some notices is worth resolving before booking, not after invoicing.
