- Carrier demurrage & detention tariff for the relevant trade lane
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.
Importers routing through Busan — South Korea's mega-hub and the transshipment crossroads of Northeast Asia, split between the North Port and Busan New Port — face the same two-clock reality as every major gateway: carrier demurrage on the box and terminal storage on the ground slot. This tool models the demurrage layer with Busan-realistic defaults (5 free days, escalating to $235/day).
About Port of Busan Demurrage Calculator
Two port areas with separate terminals mean inter-terminal transfers (ITT) — a relay box moved between areas can accrue handling you didn't book. That local context matters when disputing: charges driven by the port's own dynamics rather than your idleness are the recoverable kind, and knowing the pattern is half the evidence. Work the math before the deadline, not after: enter days since discharge, your contracted free time and the tariff tiers. The per-tier breakdown mirrors how the carrier's billing system itemises the invoice, so any mismatch you find is a concrete dispute line — not a feeling that the bill is high.

Frequently asked questions
How much demurrage would a container at Busan owe after 11 days?+
Under the preloaded example (5 free days, then $90 for 4d, $150 for 4d, $235 after): 6 chargeable days = 4 × $90 + 2 × $150 = $660 per container. Your tariff's actual brackets may differ — edit the tiers to match before relying on the figure.
What triggers the demurrage clock at Busan?+
Carrier tariffs key the clock to discharge or availability, and at Busan the distinction matters during heavy vessel exchanges when availability notices lag the crane. Compare the notice timestamp on your arrival notice with the invoice's day one — mismatches there are the easiest demurrage dollars to recover.
What is an ITT charge on a Busan invoice?+
Inter-terminal transfer: your box was physically trucked between Busan New Port and North Port terminals to meet its connection. For transshipment under a through-bill it's usually the carrier's cost; if it surfaces on your import invoice alongside demurrage, query who ordered the transfer before paying either line.
Does this calculator cover detention (per diem) too?+
The math engine handles any free-time-plus-tiers structure, so yes — switch the inputs to your detention free days and per-diem tiers and it prices the after-gate-out leg identically. Just don't mix the two tariffs in one calculation; carriers bill them as separate line items with separate clocks.
