The most common costing error in small import businesses is simple: pricing from the supplier's invoice.
The invoice is the smallest component of what the goods actually cost you by the time they are on your shelf. The number you need is landed cost, and building it correctly is the difference between a margin and a loss.
| Component 1 | goods value |
|---|---|
| Component 2 | freight and insurance |
| Component 3 | duty and taxes |
| Component 4 | port, clearance and handling charges |
| Component 5 | inland transport and storage |
| Component 6 | losses, financing and currency |
The compounding mechanism
The point that surprises new importers is that these components are not simply added. Several are calculated on top of others.
Customs duty is normally charged on a customs value that already includes freight and insurance, not on the bare invoice price. Then consumption taxes are usually charged on a base that includes the duty.
The practical consequence: a change in freight cost changes your duty as well, and a change in duty changes your tax. The effects multiply rather than add.
This is why a shipment quoted at a good price can still land badly. It is also why cheap goods with expensive freight often work out worse than the reverse.
Building the number
Work through it in order:
- Goods value — the invoice, including any commissions and packing charged separately
- Add freight and insurance to reach the value customs will assess
- Apply duty at the rate for the correct classification of the goods
- Apply other border charges — service charges, environmental levies and similar, which vary by jurisdiction and by product
- Apply consumption tax on the base that includes the above
- Add clearance and handling — broker fees, port and terminal charges, documentation fees, any demurrage
- Add inland costs — transport from port, unloading, storage
- Add the invisible costs — damage and shrinkage, the cost of capital tied up while goods are in transit, and bank charges on the payment
Then divide by the number of sellable units. That figure is your true cost, and it is the only one you should price from.
The costs importers most often omit
Demurrage and storage. Containers and cargo left at the port beyond a free period accrue daily charges that escalate. These are entirely avoidable and yet they are one of the biggest unplanned costs in small importing.
The cause is almost always the same: documents not ready when the goods arrive. The fix is to have clearance paperwork complete before the vessel docks, not after.
Cost of capital. Money paid to a supplier is unavailable until the goods are sold. On a long shipping route this can be months. For a business using an overdraft or a loan, that is a real financing cost belonging to the shipment.
Currency. If you pay in one currency and sell in another, both the exchange rate and the conversion spread affect cost. As covered elsewhere on this site, the spread is often larger than the visible fee.
Small-order penalty. Fixed costs — clearance, documentation, minimum freight — spread over fewer units. A small trial order can have a landed cost per unit several times higher than a full container. This matters because founders often test with a small order, get a bad cost, and draw the wrong conclusion about viability.
Shrinkage. Damage in transit, breakage, and goods that arrive unsellable. Build a realistic percentage in rather than treating each incident as an exception.
Where the leverage is
Once the components are separated, it becomes clear which ones are worth attacking:
- Order size — usually the largest single lever, because it spreads fixed costs
- Consolidation — combining orders with other importers to fill a container
- Classification — making sure goods are classified correctly, since rates differ by category
- Preferential origin — goods qualifying under a trade agreement may attract a reduced rate
- Clearance speed — eliminating demurrage entirely is free money
- Payment terms — reducing the time your capital is tied up
The third and fourth are covered in their own articles on this site, because both are technical enough to get wrong and expensive enough to matter.
A discipline worth adopting
Keep a landed-cost sheet per shipment, and compare planned to actual after every one.
Two things come out of this habit:
Your estimates improve, because you find out which components you consistently underestimate.
You catch errors — a charge applied twice, a rate that changed, a broker fee that drifted upward. These are common and almost nobody checks.
The general principle is the one that governs all costing: a cost you have not measured is a cost you cannot manage, and in importing the unmeasured costs are usually the ones eating the margin.
Frequently asked questions
What is landed cost?
The total cost of getting goods to your premises ready to sell — goods value plus freight, insurance, duty, taxes, clearance, inland transport and the invisible costs of financing and shrinkage.
Why do the components multiply rather than add?
Because duty is usually charged on a value that already includes freight and insurance, and consumption tax is charged on a base that already includes the duty.
Which unplanned cost is most avoidable?
Demurrage and port storage. It is almost always caused by documents not being ready when goods arrive, and the fix is to complete clearance paperwork before the vessel docks.
Why can a small trial order mislead?
Because fixed costs spread over fewer units, so the landed cost per unit can be several times higher than at full volume — leading founders to wrong conclusions about viability.
