Incoterms, Demurrage & Detention — Steel Coil Risk Traps Explained

You negotiated a good coil price.

Shipment arrives.

Customs clearance delays 4 days.

Port free time expires.

Now you owe:

Demurrage
Detention
Storage
Truck waiting fees

What looked like a profitable order becomes a cost problem.

Steel coil shipments are particularly exposed to:

Heavy container handling
Weight limits
Slow unloading
Customs review
Anti-dumping checks

Understanding how Incoterms interact with demurrage and detention is critical.

This guide explains:

What demurrage is
What detention is
How Incoterms shift risk
Why coil shipments are high-risk
How to protect your margin

1. What Is Demurrage?

Demurrage is charged when:

A container stays too long inside the port terminal after arrival.

Ports allow limited “free time.”

After that, daily charges apply.

Example:

Free time: 5 days
You collect container on day 8
You pay 3 days demurrage

Demurrage is port-based.

2. What Is Detention?

Detention is charged when:

You remove container from port but return it late.

Example:

Free time: 7 days
You return container after 10 days
You pay 3 days detention

Detention is container-based.

3. Why Steel Coil Is High-Risk for Charges

Steel coil creates operational delays because:

It is heavy
It requires cranes or forklifts
It may require top unloading
It cannot be rushed
It may require weight permits

Unloading 25–27 tonnes of coil safely takes time.

Poor planning leads to detention fees.

4. Incoterms and Responsibility

Incoterms determine who pays which charges.

But many buyers misunderstand where responsibility ends.

Under EXW

Buyer responsible for:

Freight
Port clearance
Demurrage
Detention

Risk is fully buyer-controlled.

Under FOB

Seller handles shipment to vessel.

Buyer responsible after loading.

Demurrage and detention at destination are buyer’s responsibility.

Under CIF

Seller pays freight and insurance.

BUT:

Risk transfers at shipment port.

Demurrage and detention at destination are buyer’s responsibility.

CIF does NOT protect you from port delays.

Under DDP

Seller responsible until delivery at buyer’s premises.

Demurrage and detention usually seller responsibility.

However:

If buyer delays customs clearance, liability may shift.

DDP must clearly define customs cooperation.

5. Free Time Trap

Free time varies by port and shipping line.

Typical free time:

5–7 days

But:

Customs inspection may take longer.

If anti-dumping review triggered, clearance can take weeks.

Without planning, demurrage accumulates daily.

Steel containers are expensive to store.

6. Weight & Transport Permit Delays

Steel coil containers often approach:

Maximum legal weight.

Some countries require:

Special heavy load permits.

Permit delay = detention cost.

Plan transport before vessel arrival.

7. Customs Inspection Risk

Steel imports may trigger:

Random inspection
Trade compliance check
Anti-dumping review

Inspection delays count against free time.

Even if you are not at fault, port charges continue.

Insurance does NOT cover demurrage.

8. Documentation Errors = Financial Loss

If invoice or packing list incorrect:

Customs clearance slows.

Demurrage accumulates.

The cost of paperwork error can exceed profit margin.

Documentation precision reduces risk.

9. Storage Space & Unloading Capacity

Before container arrives, confirm:

Crane availability
Forklift capacity
Space to store coils
Skilled labor availability

If you cannot unload promptly:

Detention fees are predictable.

10. Container Return Rules

Shipping lines require:

Clean container
No damage
Timely return

If coil scratches container floor:

Repair cost may be charged.

Return late = detention cost.

Understand depot return location.

11. Anti-Dumping & Trade Review Delays

Steel is often subject to:

Safeguard duties
Anti-dumping measures

If customs questions origin or classification:

Container may be held.

This increases demurrage exposure.

Proper HS code and documentation reduce risk.

12. Practical Risk Control Checklist

Before shipment:

✔ Confirm Incoterm responsibility
✔ Confirm free time allowance
✔ Confirm customs broker ready
✔ Confirm transport booked
✔ Confirm unloading equipment available
✔ Confirm warehouse capacity
✔ Review documentation accuracy

Preparation reduces cost.

13. Negotiation Strategies

When negotiating contract:

Ask for:

Extended free time
Demurrage sharing clause
Clear DDP language
Clear customs responsibility clause

Prevention is cheaper than dispute.

14. Real-World Example

Coil shipment CIF basis.

Buyer assumes freight covered, so safe.

Container arrives.

Customs review takes 10 days.

Free time was 5 days.

Buyer pays 5 days demurrage.

CIF did not protect from port delay.

Understanding risk transfer is critical.

15. Common Buyer Mistakes

Assuming CIF covers port delay
Not checking free time
Not pre-booking transport
Not verifying documentation
Not checking heavy load permit rules
Ignoring anti-dumping risk
Waiting until vessel arrival to prepare

Steel imports require pre-arrival planning.

16. FAQ Section

Does CIF include demurrage?

No.

Does DDP eliminate demurrage risk?

Usually seller responsibility, but clarify.

Is demurrage covered by insurance?

No.

Who pays detention under FOB?

Buyer at destination.

Can demurrage be negotiated?

Sometimes, but difficult after arrival.

Does customs delay stop demurrage?

No.

Should free time be confirmed in writing?

Yes.

Is steel more likely to be inspected?

Often yes.

Can heavy weight cause delay?

Yes.

How to reduce risk?

Preparation before vessel arrival.

17. Conclusion

Incoterms define:

Risk transfer
Cost allocation

But they do NOT eliminate:

Demurrage
Detention
Port storage

Steel coil shipments are especially exposed because of:

Weight
Handling complexity
Trade scrutiny

Professional buyers:

Confirm responsibility
Plan unloading
Prepare documentation
Pre-book transport
Understand free time

Demurrage is rarely accidental.

It is usually a planning failure.

Understanding these traps protects your profit.
