Matson Demurrage & Detention Calculator
Recompute Matson D&D invoices: free time, tiered daily rates and per-container totals with an editable tariff.
Set a tier's days to 0 to mean “all remaining days”.
Defaults approximate a common Matson import structure — pull the exact brackets from Matson's published per-country D&D tariff for your trade lane and equipment type.
With your numbers: 8 days − 3 free = 5 chargeable days = 3×$165 + 2×$250 = $995 per container.

- Matson — published demurrage & detention tariff (per country/trade)
- FMC 46 CFR Part 541 billing requirements (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.
Auditing a Matson demurrage or detention invoice starts with one question: do the free days and tier rates on the bill match the filed tariff for your country and equipment type? Matson — the US Jones Act carrier linking the mainland with Hawaii, Alaska and Guam, plus an expedited China service — publishes those tariffs; this tool recomputes the math once you've pulled the right column.
About Matson Demurrage & Detention Calculator
Its CLX expedited trans-Pacific product guarantees fast vessel-to-gate times — free time is short because the entire product is built around velocity. Operational details like this are why carrier-specific calculators beat generic ones: the failure modes differ line by line. Defaults model a typical import scenario (3 free days, 8-day dwell, tiers of $165×3d, $250×3d, $350+). Edit everything. The per-tier breakdown is intentionally formatted like a carrier billing line so a mismatch jumps out — and a mismatch, documented, is a dispute with a number on it.

Frequently asked questions
Where do I find Matson's official D&D tariff?+
On Matson's website under demurrage & detention (filed per country and direction, usually with effective dates). Use the document in force on your container's discharge date and the column matching your equipment type — then enter those free days and brackets here to recompute the invoice exactly.
What would 8 days on the clock cost with Matson-typical rates?+
With the preloaded example (3 free days, then $165 for 3d, $250 for 3d, $350 after): 5 chargeable days = 3 × $165 + 2 × $250 = $995 per container. Treat it as a calibration point, not a quote — your filed tariff governs.
Why is Matson free time shorter than other carriers?+
The CLX product's promise is speed — dedicated terminals and fast availability — so its tariff assumes prompt pickup and prices dwell steeply. If you ship Matson for the velocity, build drayage capacity for arrival day: the service's economics (and your D&D exposure) both assume the box moves immediately.
How do I request a Matson free-time extension?+
Before charges accrue, through your booking contact or the carrier portal, citing the specific cause (vessel delay, exam hold, appointment scarcity) with dates and evidence. Carriers grant documented, cause-specific requests far more readily than post-invoice waiver pleas — by the time it's an invoice, it's a dispute instead.
