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. This letter is a template, not legal advice.

Demurrage and detention disputes succeed on structure: a clear timeline, a recognised ground, and evidence attached — not an angry email. This generator assembles those parts into a formal dispute letter you can PDF and send to the carrier's billing or disputes desk, citing the US FMC billing rule where it strengthens your position (for non-US trades, the same structure works minus the citation).
About Demurrage Dispute Letter Generator
Pick the ground that actually fits. 'No appointments available' and 'container under customs hold' are the highest-success categories because they map directly onto the FMC's incentive principle — a charge can't incentivise pickup of a box that physically couldn't be picked up. 'Invoice lacks required details' is the procedural fallback: since 2024, US-billed D&D invoices must contain specific fields, and missing ones make the invoice itself defective. Send disputes fast and keep paying undisputed lines. Most carrier tariffs set a 30-day dispute window from invoice date, and withholding an entire invoice over one bad line item gives their collections team the moral high ground. One letter per invoice, evidence enclosed, and a named contact for the reply — that's the format billing teams actually process.

Frequently asked questions
What are the strongest grounds for a D&D dispute?+
Unavailability: the container couldn't be retrieved (no appointments, customs exam, terminal closure, vessel bunching) or the empty couldn't be returned (depot refusals). These align with the FMC's incentive principle. Contract misapplication — wrong free time or rate versus your service contract — is equally strong but needs the contract clause quoted.
How long do I have to dispute a demurrage invoice?+
Check the invoice and tariff — 30 days from invoice date is the most common window in carrier tariffs, and the FMC rule requires the invoice to state the dispute process and timeframe. Missing that window converts a winnable dispute into a goodwill request, so calendar it the day the invoice lands.
Does the FMC rule apply to my shipment?+
The 46 CFR Part 541 billing requirements cover demurrage/detention invoiced by VOCCs, NVOCCs and MTOs for US imports/exports. Outside US trades the rule doesn't bind, but its structure — itemised days, identified billing party, stated dispute path — is still the de-facto template carriers respond to.
Should I withhold payment while disputing?+
Withhold only the disputed line items, never the whole invoice, and say so explicitly in the letter (the generator includes this). Full non-payment risks credit holds on future releases, which costs far more than the disputed days. Carriers generally won't send a properly disputed line to collections while it's under review.
