Many shippers assume that the 40-foot high cube container they have always used for shipping building materials to Kuwait City will remain the most cost-effective option. This belief often leads to overlooked demurrage risks when the container size no longer matches the consignee’s unloading capacity or the terminal’s available equipment. A quick call to a local Kuwait forwarder before booking could save thousands of dollars in detention charges.

Pitfall 1: Assuming Your Usual Container Size for Shipping Building Materials to Kuwait City Is Still Valid Without Checking Port Updates
Problem: You have been using 40GP containers for ceramic tiles and 20GP for steel bars, but recent infrastructure changes at Shuwaikh Port and Shuaiba Port have altered equipment availability. Some vessels now only accommodate 40HC for overweight cargo, while terminal cranes may restrict height for certain building materials like prefabricated panels.
Cause: Port operators in Kuwait have invested in new STS cranes with specific lifting capacities. Additionally, the ongoing expansion of the Shuwaikh Container Terminal means temporary berth restrictions that affect container size compatibility. If your usual 40HC is suddenly not allowed, you could face a container swap at origin, leading to missed sailing and demurrage risk at destination.
Solution: Before booking, ask your Kuwait forwarder to confirm the current dimensional limits and free-time policy at the discharge port. Request a written confirmation that your preferred container size for shipping building materials to Kuwait City is accepted by the carrier and the terminal. A 15-minute check can prevent a 14-day demurrage dispute.
Pitfall 2: Ignoring Free-Time Differences by Container Size
Problem: Many shippers believe free days are the same regardless of container size. In Kuwait, however, the standard free time for 20-foot containers is often 7 days, while 40-foot containers may get only 5 days due to higher yard occupancy. If your consignee needs extra time to clear customs for building materials (e.g., marble slabs requiring SABER certification), a 40HC could rack up demurrage faster than a 20GP.
Cause: Terminals allocate yard space based on container footprint and weight. Larger containers are moved more frequently, so carriers impose stricter free-time limits to encourage quick pickup. Building materials like cement or heavy machinery often require special handling, further delaying release.
Solution: Ask your forwarder for the exact free-time allowance for each container size at the specific terminal (Shuwaikh vs Shuaiba). Negotiate a 3–5 day extension in the booking note if your cargo is time-sensitive. Alternatively, consider splitting the shipment into two 20-foot containers to get longer free time and lower demurrage exposure.
Pitfall 3: Overlooking Demurrage Waiver Cut-off Dates
Problem: Carriers and terminals periodically offer demurrage waivers during holidays or low-season periods. If you assume your usual container size for shipping building materials to Kuwait City still works without checking the waiver calendar, you may miss opportunities to reduce costs. For example, during Ramadan, some terminals extend free time by 3 days for 20-foot boxes but not for 40-foot ones.
Cause: Demurrage policies are dynamic and size-specific. A forwarder who works daily with Kuwait port authorities will know which container sizes qualify for waivers in the upcoming quarter. Relying on outdated tariff sheets from last year is a common mistake.
Solution: Ask your Kuwait forwarder to provide a timeline of expected demurrage waivers for the next 90 days. Cross-check this with your estimated arrival window. If a waiver for 40HC is unlikely, you might adjust the container size or schedule the shipment earlier to avoid peak surcharge periods.
Pitfall 4: Misjudging Weight vs Volume for Building Materials
Problem: Your usual container size for shipping building materials to Kuwait City might be a 40HC because you always have high-volume, low-weight cargo (e.g., insulation panels). But if the consignee suddenly orders heavy structural steel, the same 40HC could exceed the road weight limit on Kuwait’s highways, resulting in forced splitting at the port and additional demurrage.
Cause: Kuwait enforces strict axle weight restrictions for trucking from the port to the warehouse. A 40-foot container fully loaded with steel often surpasses the legal gross weight, so the container cannot be moved from the terminal until the cargo is partially discharged—a process that incurs demurrage and special handling fees.
Solution: Always provide the forwarder with the commodity’s exact weight and volume per package. Ask: “Is my intended container size for shipping building materials to Kuwait City still feasible given the current road limits?” They may recommend a 20GP or a 40HC with less than full fill to stay under the weight cap.
Final Checklist Before Booking
- ✅ Confirm with a Kuwait-based forwarder the free-time policy per container size at the destination terminal.
- ✅ Verify equipment availability (crane reach, chassis supply) for your usual container type.
- ✅ Request a demurrage risk assessment based on the latest terminal circulars (ask for a reference from last month’s changes).
- ✅ If your cargo includes dangerous goods (e.g., lithium batteries for construction tools), double-check whether the container size affects segregation rules.
- ✅ Always ask: “Is the container size for shipping building materials to Kuwait City that I’ve always used still the safest choice for this shipment?”
Bottom line: Demurrage risks in Kuwait are rapidly evolving. A trusty 40HC may become a liability if you don’t verify port conditions first. Spend 10 minutes contacting a Kuwait forwarder—it’s the cheapest insurance you’ll ever buy.
