When shipping a portable home overseas, a single small mistake can lead to delays, extra fees, or even damaged goods. Many buyers think shipping is straightforward—pay, load, and wait. But international logistics can be tricky, and knowing the pitfalls can save thousands.
Below are the most common mistakes exporters and buyers face, and how you can avoid them.
1. Poor Documentation and Missing Paperwork
International shipping is strict. Even one missing document can stop your container at the port.
Common Issues:
Missing invoice
Incomplete packing list
No HS code
Incorrect consignee information
Certification errors (especially for building materials)
✔ How to Avoid It
Prepare all documents before booking the vessel.
Use a standardized packing list with exact dimensions and weights.
Always confirm your destination country’s building material requirements.
Example:
A buyer shipping a portable villa to Thailand forgot to include the HS code. The shipment was held for 4 days, costing $680 in storage fees.
2. Choosing the Wrong Container Size or Type
Portable homes are big items, and choosing the wrong container causes wasted space or unexpected costs.
Typical Mistakes
Booking a 40HQ when a 20GP fits the cargo
Forgetting to consider length after folding
Not checking maximum load limits
Using standard containers instead of open-top for oversized units

✔ How to Avoid It
Ask your supplier for container optimization layout before shipping.
Use load-planning software or request a 3D packing layout.
Confirm weight limits: some ports reject overweight containers immediately.
Example:
A customer in Canada booked a 40HQ but only filled half the space. After rechecking, they downsized to a 20GP and saved over $900.
3. Forgetting to Secure the Portable Home for Long Sea Travel
A portable home is strong, but sea movement is stronger.
Common Mistakes
Walls not strapped
Floors not fixed with steel bands
Windows not cushioned
Loose hardware packed randomly
✔ How to Avoid It
Use foam blocks and protective padding on all fragile parts.
Tighten all modules with steel straps.
Ensure nothing can slide, fall, or shake during shipping.
Example:
A builder shipping to Chile didn’t secure a kitchen module. Heavy waves caused damage, costing over $1,500 in repairs.
4. Ignoring Country-Specific Import Restrictions
Every country has different rules for portable homes.
What Many Buyers Overlook
Electrical certification (CE, UL, GCC)
Thermal insulation standards
Wooden material fumigation requirements
Fire-rating documents (especially in EU + UAE)
✔ How to Avoid It
Check destination regulations before production begins.
Ask your supplier for compliance documents.
Confirm if your portable home qualifies as:
“Building material”
“Temporary structure”
“Modular housing unit”
Different categories = different import taxes.
Example:
A buyer in Saudi Arabia paid an extra 5% duty because their portable home was classified as a “prefabricated building” instead of “construction equipment.”
5. Not Double-Checking Hidden Local Fees
Even with the best shipping rate, port side costs can surprise you.
Common Hidden Fees
Port storage charges
Demurrage
Detention
THC fees
Warehouse unloading fees
Documentation charges
ISPS charges
✔ How to Avoid It
Ask for a breakdown before confirming your quote.
Choose all-in quotes from trusted freight forwarders.
Clear customs in advance to avoid storage fees.
Example:
A customer in South Africa was surprised by a $450 THC charge because the freight forwarder didn’t include it in the quote.
6. Not Insuring the Shipment
Many buyers skip insurance to save money—but this is risky.
What Can Go Wrong
Water damage
Storm impact
Lost container
Collision
Dropped cargo during loading
✔ How to Avoid It
Get at least basic marine insurance (very affordable).
For high-value units, choose full-value protection.
Always check exclusions such as “improper packing” rules.
Example:
A portable cabin shipped to Mexico was damaged due to crane handling. The buyer had insurance and recovered $4,800.
7. Poor Communication Between Supplier and Shipper
When supplier, forwarder, and buyer don’t align, mistakes happen.
Common Outcomes
Wrong sailing date
Incorrect booking details
Last-minute container change
Missing documents
Wrong HS codes
Unclear incoterms22
✔ How to Avoid It
Create a simple group chat with all parties.
Confirm:
Container type
Vessel ETD
File submission deadline
Incoterms
Packing details
Request photo proof of the container loading process.
Example:
A buyer in Kenya avoided detention fees because the supplier sent real-time loading photos, allowing the forwarder to prepare documents early.
Conclusion
Shipping a portable home overseas can be safe, smooth, and cost-effective—if you avoid the most common mistakes. By preparing documents early, choosing the right container, following import rules, and coordinating closely with your freight forwarder, you protect your budget and ensure your portable home arrives safely and on time.
