Customs Demurrage: Why It Builds Up and How to Reduce It
“Customs demurrage” is the everyday name for the storage and demurrage cost that grows while cargo waits for Customs clearance. We help you see what you are being billed, why, and what can be done about it.
What does “customs demurrage” actually mean?
Strictly speaking, Customs does not send you a demurrage invoice. The charges come from two other parties: the shipping line, which bills demurrage when the container stays in the port past free time, and the port, terminal or CFS, which bills storage or ground rent when cargo sits in the yard.
Traders call it customs demurrage because the clock keeps running while Customs steps are still pending: filing the Bill of Entry, assessment, duty payment, examination and out-of-charge. If any of those steps stall, free time runs out and the charges begin.
That connection matters. When the delay sits inside the Customs process and you responded promptly, you have a legitimate basis to ask for relief.
Where time is lost between arrival and gate-out
Every import passes through the same stages. Knowing where your cargo stalled tells you who to talk to.
Vessel arrives and the manifest is filed
Free time at the terminal usually starts from discharge. A manifest error or amendment can hold up everything after it.
Bill of Entry is filed
Filing before arrival saves days. Late or incorrect filing is the most common self-inflicted delay.
Assessment and queries
Customs may question value, classification or documents. Slow replies, from either side, cost free time.
Duty payment
Clearance cannot move until duty is paid. Interest applies if payment is late.
Examination, if selected
Physical checks, sampling or lab testing can take days, and the schedule is not in your hands.
Out-of-charge, Delivery Order, gate-out
Only after these can the container leave. Any wait here still counts against free time.
Delay you can control versus delay you cannot
This split largely decides how strong a waiver request is. Be honest with yourself about which column your case belongs in.
Usually within your control
- Bill of Entry filed late
- Incomplete or mismatched documents
- Duty paid late
- Wrong classification or value declared
- Slow replies to Customs queries
Often outside your control
- Customs or port system downtime
- Waiting in the examination queue
- Lab testing or sample reports
- Officer queries pending on the department's side
- Holidays, strikes and yard closures
How to keep customs demurrage down
A few habits do more than any negotiation afterwards.
File before the vessel arrives
Pre-arrival filing lets assessment start while the ship is still at sea.
Answer queries the same day
Keep a named person responsible for Customs queries, and track them daily.
Ask for more free time early
Write to the line before free time expires and explain the pending Customs step.
Keep the Delivery Order valid
An expired DO is a quiet cause of extra days. Check its validity date.
Log every Customs event
Dates and screenshots of queries, examination orders and out-of-charge become your evidence.
Call us before the bill grows
Early involvement lets us request free-time extensions while they are still possible.

Frequently asked questions
Is customs demurrage charged by Customs?
Not directly. The shipping line charges demurrage and the port, terminal or CFS charges storage. Customs delays are often the reason these charges accumulate.
How can I reduce demurrage while Customs clearance is pending?
File the Bill of Entry early, respond to queries immediately, pay duty promptly, keep the Delivery Order valid, and ask the shipping line in writing for more free time before the existing free time ends.
What happens if cargo stays uncleared for a long time?
Charges keep growing every day. Under Section 48 of the Customs Act, goods left uncleared for 30 days after unloading can be sold after notice, so long delays carry a risk beyond cost.
Can I get a waiver if Customs examination caused the delay?
It is one of the stronger grounds, especially with records showing when the examination was ordered and completed. The decision still rests with whoever is charging.
How is this different from shipping line demurrage?
The shipping line demurrage is the charge itself. “Customs demurrage” describes the situation where Customs steps cause it. See our page on shipping line demurrage.
Who has to pay these charges?
Usually the importer, under the contract and the terms of the Bill of Lading. Where the delay was caused by a third party, the cost may be recoverable, and we can review that with you.
