What Is Demurrage — and Why It Can Cost You More Than Your Freight

You have paid your freight invoice. Your goods are on the water. Then, weeks later, a bill arrives from a company you have never heard of — for an amount that sometimes exceeds what you paid for shipping. This is demurrage, and it is one of the most common financial surprises in international freight.

What Is Demurrage?

Demurrage is a fee charged by the shipping line when an import container is not collected from the port within the free time window. Free time is the number of days the shipping line allows the container to sit at the destination port at no charge after it is discharged from the vessel. Once that window closes, demurrage begins.

The free time period varies by shipping line and destination port. Common windows are 7 days, 10 days, or 14 days. After that, daily charges apply — and they escalate quickly. A standard demurrage rate might start at USD 50 per day and step up to USD 150 or more per day after the first week of delay.

What Is Detention?

Detention is related but different. Demurrage is charged when the container sits at the port. Detention is charged when the container has been collected from the port but the empty container is not returned to the shipping line's depot within the allowed free time.

In practice, both charges can apply to the same shipment. You collect the container late, you pay demurrage. Then you are slow to unpack and return the empty, you pay detention on top.

Why Does It Happen?

The most common reasons demurrage accumulates:

• The customs broker was not appointed before the goods arrived, so clearance could not begin immediately.

• Documentation was missing or incorrect — the customs broker could not lodge the entry without the correct papers.

• The consignee was not ready to collect — warehouse not arranged, transport not booked.

• Customs held the container for inspection — this is outside everyone's control, but the clock still runs.

  
  

Who Pays It?

Demurrage and detention are the consignee's responsibility at destination. They are not included in any freight quote from PT Intai Rainbow — they cannot be, because they depend entirely on how quickly the receiver acts at their end.

This is why we include a demurrage education note with every new shipment and require the customer to acknowledge it in writing before the booking is confirmed. It is not a formality. It is protection for you.

How to Avoid It

• Appoint your customs broker before the vessel arrives. Not when it arrives. Before.

• Make sure all import documents are ready and correct before the estimated arrival date.

• Know the free time period for your specific shipping line and port combination — ask your broker.

• Have your warehouse and transport arranged before the vessel docks.

• Return the empty container promptly once goods are unpacked.

Demurrage is not charged by PT Intai Rainbow. We have no control over it once the goods leave the origin port. But we tell every customer about it before they book, because a shipping surprise of this kind — arriving weeks after the main freight invoice — is one that could have been avoided with a little preparation at the destination end.
