AnalysisDetention and delay · Check before you bargain
Can I negotiate demurrage charges, or is the invoice simply wrong?
Demurrage is negotiable in the ordinary commercial sense, and negotiating is the second move rather than the first. Since 28 May 2024 a US demurrage or detention invoice has to reach the billed party within 30 days and carry 20 specified elements. An invoice failing either test carries no obligation to pay, which is a stronger position than a discount. Of the 86 pages SeaRates measured on this cluster, 7 explain the rule.
Four tests to run before replying
- Did the invoice arrive within 30 days of the charge
ceasing to accrue? Late is not a technicality under the rule; it is the rule.
- Does it carry all 20 required elements? Identifying information, the dates the charge covers,
the rate and where the tariff publishing it can be read, the dispute process and the certification. A missing element is a defect in the invoice.
- Was the cargo actually available? Time when the container could not be retrieved — no
appointment offered, terminal closed, cargo under a hold not of your making — is contestable on the facts.
- Is the same day billed twice? One delay can generate a terminal demurrage line and a carrier
detention line legitimately. It can also generate the same day billed by both under the same name.
What the five groups of elements cover
| Group under 46 CFR 541.6 | What must be on the invoice |
|---|---|
| Identifying information | Bill of lading, container, port, the billed party |
| Timing | The dates the charge covers and when free time expired |
| Rate and authority | The rate applied and where the tariff can be read |
| Dispute process | How to contest it, to whom, and by when |
| Certification | That the charge complies and is accurately calculated |
The dispute row is the one most often missing, and it is also the one that starts your clock. An invoice that does not tell you how to contest it has not given you the process the rule requires.
Where negotiation actually works
Once the invoice survives the four tests, the commercial conversation is real and has a shape. Carriers and terminals routinely waive or reduce charges where the delay was caused on their side, where a customer relationship is at stake, or where the alternative is a formal complaint with a documented case behind it.
What moves it is evidence, assembled in one message: the gate transactions, the appointment attempts with timestamps, the hold notice and its release, and the tariff page the rate is supposed to come from. What does not move it is a request for goodwill with no file attached.
Keeping the clock from starting
The cheapest demurrage is the invoice that never opens. Four things do most of the work: file the customs entry before arrival rather than after; confirm the last free day in writing at booking rather than assuming the tariff minimum; book the drayage appointment as soon as the vessel schedule firms; and check whether the consignee's own paperwork — not the carrier's — is the thing holding release.
Free time is 3 to 7 days at most US terminals. On a $200-a-day tier that is the difference between a clean file and a four-figure line nobody budgeted.
Where this goes next
Three pages carry the rest of this question: the number behind it, the comparison of whoever would do it, and the check that runs before you pay.
- the invoice rule that can cancel the charge — the figure behind it
- capacity, reliability and orderbook, ranked separately — who does it
- the licence and bond behind the company name — check the licence
Two neighbouring pieces sit closer to this one than any of them: Do cars get damaged during shipping, and Are freight forwarders worth it.
Frequently asked questions
Can I negotiate demurrage charges?
Yes, but check the invoice first. Under the FMC rule in force since 28 May 2024 it must arrive within 30 days and carry 20 required elements; an invoice missing one carries no obligation to pay, which is stronger than a negotiated discount.
Who pays for demurrage charges?
The party the carrier or terminal billed under the contract of carriage, usually the consignee or the party named on the bill of lading. A forwarder billed as contracting party normally passes it through.
How do I dispute a demurrage invoice?
Reply inside the window the invoice states, in one message, with the gate transactions, timestamped appointment attempts, any hold notice and release, and the tariff page the rate is supposed to come from.
How to check demurrage charges?
Match the billed days against the terminal and carrier tariffs, confirm when free time expired, and check that the same day is not billed twice under two names by two parties.
What are demurrage charges at the port?
The terminal charge for cargo occupying the yard past its free time, published in the terminal tariff and typically tiered so later days cost more. Published US figures run $75-300 per container per day.
