Tariffs get all the attention, but they're not the only costs eating into your import margins. Here are seven commonly overlooked expenses that can add 5-15% to your landed cost if you're not prepared.
If your container sits at the port longer than the free time allowed (typically 3-5 days), you start paying demurrage fees of $150-400 per day. Detention charges apply if you keep the container past the allotted time. These costs add up fast during port congestion.
How to avoid: Have your customs clearance paperwork ready before the vessel arrives. Use a reliable customs broker who clears entries within 24-48 hours.
If CBP selects your shipment for examination (X-ray, tailgate, or intensive), you'll pay $300-1,000+ in exam fees plus potential demurrage while waiting. About 3-5% of entries are examined.
How to prepare: Budget $500 per shipment as an exam contingency. Maintain accurate documentation to reduce your exam rate over time through C-TPAT membership.
Certain products from specific countries face additional anti-dumping (AD) or countervailing duties (CVD) on top of regular tariffs. These can add 20-300%+ to your duty bill. Common products affected include Chinese steel, plywood, mattresses, and cabinets.
How to check: Search the ITC's AD/CVD orders database before sourcing. These duties are in addition to Section 301 and Section 122 tariffs.
Every importer needs a customs bond. A continuous bond costs $500-2,000+ per year depending on your import volume. Single-entry bonds are available but cost more per shipment.
These get overlooked because they're small percentages — MPF at 0.3464% and HMF at 0.125%. But on a $100,000 shipment, that's $471 in fees. Our Landed Cost Calculator includes these automatically.
Freight forwarders earn money on the spread between what they pay carriers and what they charge you. Getting quotes from 3-4 forwarders or using platforms like Easyship can save 10-20% on shipping costs — which also reduces your customs value and tariff bill.
If you pay suppliers in their local currency, exchange rate movements can add 2-5% to your costs between when you agree on a price and when you actually pay. Consider locking rates with forward contracts for large orders.
💡 Rule of Thumb
Add 8-12% on top of your calculated landed cost as a buffer for hidden and unexpected costs. This prevents margin surprises and gives you a more realistic profit calculation.
