Is your demurrage & detention invoice valid?

Ocean carriers often get demurrage & detention invoices wrong — and under the FMC billing rule, you may not owe what they billed.

DDClear checks your invoice against 46 CFR Part 541 — missing fields, late billing, over-charged rates, and charges for days your container couldn't be moved — and shows what may not be owed. Free, and private by design.

For importers, exporters, freight forwarders / NVOCCs, and 3PLs handling ocean demurrage & detention invoices.

Private by design — we read it, judge it, and forget it. Nothing confidential is stored.

Paste your invoice

Most people paste it straight from the carrier's email — or drop a PDF/photo. We read it two ways, and DDClear's rules engine judges it against the rule when you check — you don't re-enter anything.

Which invoice is this?

A carrier billed me — find defects to dispute

I'm billing my shipper — check it holds up before you bill

Anything that made the container impossible to move?

Optional — potential grounds to document. DDClear flags these; it does not decide them. Checking a box does not change the pass / fail / void result — it only adds a ground for you to document.

The terminal was closed on a day you were charged

The cargo was under a customs hold

The container wasn't actually available to pick up

No pickup or return appointment was available

The terminal refused to take the empty container back

Free while we learn — no account, no card.

No invoice handy?

DDClear is software and analysis, not legal advice or representation. You review every result and decide what to send, in your own name. Nothing confidential is stored — the only thing we keep is an email you choose to share.

Curious first?

DDClear flags what may not be owed and drafts the dispute letter. You review it and send it in your own name — DDClear doesn't contact carriers for you.

Nothing confidential is stored — the only thing we keep is an email you choose to share. Results show amounts that may not be owed — they are not a guarantee that any amount is or is not owed.
