Frequently Asked Questions

Q: Why did my courier charge me extra after I already paid the duty? A: These are likely "Brokerage Fees" or "Advancement Fees." The courier paid the taxes to the government on your behalf and is now charging you for that service.

Q: What is a storage fee at the port? A: Known as Demurrage, this is a daily penalty charged by the port if you don't pick up your container within the "free days" allowed (usually 3–5 days).

Q: Are security surcharges real? A: Yes. Following global security events, many ports and airlines charge a "Security Surcharge" for X-ray scanning and manifest screening.

Hidden Costs in International Shipping: A Warning to Importers



You've calculated your item cost, your duty, and your VAT. You think your budget is perfect. Then, the final invoice from the logistics provider arrives, and it's 12% higher than your "Landed Cost" estimate. These are the "hidden" costs of global movement.

1. Customs Brokerage & Advancement Fees

Even if you clear goods yourself, large carriers like FedEx, DHL, or UPS often charge a flat fee (e.g., $15 or 3% of the tax) just for the paperwork of clearing the package. If they "advance" the money to customs for you, they will charge an interest-like fee.




2. Terminal Handling Charges (THC)

A ship dock is a complex machine. Unloading a container from a vessel to a truck involves labor, fuel, and massive gantry cranes. The "THC" covers these costs and is rarely included in the initial "ocean freight" quote.

3. Demurrage vs. Detention

  • Demurrage: The container stays inside the port for too long.
  • Detention: You took the container to your warehouse but didn't return the empty box to the shipping line fast enough.
  • The Cost: These can scale from $75 to $400 per day per container.


  • 4. Currency Exchange Surcharges

    If you buy in USD but your duty is calculated in GBP, the customs department uses their own "Official Exchange Rate," which is updated monthly and often differs from the market rate. This can lead to a 1–2% variance in your calculated taxes.

    Always build a 5–10% buffer into your Landed Cost Estimates. For more detailed logistics breakdowns, browse the Dapplesoft News & Insights.
