Landed Cost, Not Unit Price: What EXW, FOB, CIF and DDP Actually Put on Your Invoice

Article

October 26, 2026

A shipment of metal parts, thirty-six pounds. Freight was quoted at $200. The invoice arrived at $1,200, with $370 of duty on top, and the total came close to $1,800. That account comes from a buyer describing his own order in a procurement forum — self-reported and not independently verified — but the mechanism behind it is ordinary, and it is the reason a unit price is the least useful number in a purchase order.

Every one of those figures was knowable before the order was placed. What was missing was a landed-cost calculation: a list of every cost element between the factory door and your own, and who bears each one under the trade term you agreed to.

This article puts nine cost elements against the four terms that most small and mid-sized buyers actually use, explains where risk transfers as opposed to where cost sits, and ends with a formula you can fill in with your own numbers before you compare a single quote.

The Nine Lines That Come After the Unit Price

An Incoterm does not change what shipping costs. It changes who buys each service — and therefore which of those costs appear on the supplier's invoice and which arrive later, from parties you never negotiated with.

Read the table by column. Under EXW the supplier's invoice is one line, and everything else arrives from four or five other companies, each with its own minimum charge. Under DDP it is one line and nothing else arrives — which is why a DDP price looks high and frequently is not.

EXW hides a practical trap that the table cannot show. Under EXW the buyer is responsible for the export declaration in the seller's country. A buyer with no legal entity there usually cannot make that declaration at all, so in practice the forwarder files it and bills for the service. If you are offered EXW and you have no presence in the supplier's country, ask who files the export declaration and what it costs — the answer is often the first hint that EXW was not the right term for you.

Where the Risk Transfers Is Not Where the Cost Sits

CIF is the term most often misunderstood, and the misunderstanding is expensive in a specific way. Under CIF the seller pays the main carriage and the insurance — but the risk passes to the buyer when the goods are loaded on the vessel at origin, not when they arrive at destination.

So the seller is buying insurance against a risk that has already moved to you. That is not fraud; it is how the term is drafted. What matters is the level of cover: the minimum required under CIF is the narrowest of the standard cargo clauses, and it responds to the vessel sinking, catching fire or colliding — not to pilferage, not to rain damage, not to a container left on a quay for three weeks.

If those are the risks you actually carry, the term does not cover them. Two practical responses: ask for the insurance certificate and read which clauses are named on it before you assume you are covered; and if the answer is the minimum, buy the top-up cover yourself, because it is cheap relative to the loss it addresses.

The general rule worth remembering: cost and risk move at different moments, and only one of them is printed on the invoice.

Why FOB Has the Lowest Unit Price and Often the Highest Total

FOB produces the lowest number on a supplier's invoice, because the supplier's responsibility stops when the goods are on board. That number is also the least complete, and for small shipments the missing part is disproportionately large — because the charges you absorb have fixed components that do not scale down.

Destination terminal handling is charged per bill of lading, with a minimum. A customs broker charges per entry, with a minimum. Documentation is charged per shipment. On a thirty-six pound consignment those fixed charges can exceed the freight itself, and none of them appear anywhere in the FOB price you compared.

Freight also moves. A lane quoted at $200 in one quarter can be $1,200 in another; under FOB that movement is entirely yours, and it arrives after you have already committed to the unit price. Under DDP the movement is the supplier's problem for the duration of the contract — which is part of what the higher number is buying.

And there is a volume effect. A buyer shipping two hundred kilograms a month has no freight leverage; a forwarder consolidating twenty such shipments does. Under FOB you are buying freight at retail. Under DDP the supplier may be buying it at wholesale — and may not be, which is exactly the kind of thing to ask about rather than assume.

When DDP Is the Only Sensible Choice

DDP is the only term under which the seller is the importer of record. That single fact decides most of the cases:

• You have no legal entity in the destination country, so there is no importer of record available on your side.
• You are not registered for VAT or GST and have no intention of registering for a shipment of prototype parts.
• The consignment is small enough that a broker relationship will never pay for itself.
• The parts must not sit in customs, because a prototype build is waiting on them.

DDP is the wrong term in three situations, and they are worth naming because suppliers rarely raise them:

• You already have a broker and a duty deferment account. You are then paying the supplier for a service you have already bought, and paying a margin on it.
• You need to reclaim import VAT. In many jurisdictions the party that can reclaim it is the importer of record. If that has to be you, DDP is disqualified for that reason alone, whatever the price.
• The supplier's duty estimate is built on a guessed HS code. A classification that is later corrected produces a bill, and the bill comes to whoever is the importer of record — which under DDP is the supplier, who will pass it on.

The question that separates these cases is short: who do you want to be the importer of record? Everything else follows from the answer.

A Landed Cost Formula You Can Fill In

Per part, in your own currency:

landed cost per part =
  [ (unit price × quantity) + inland to port + origin charges and documents
  + main freight + insurance + duty + destination charges + last mile
  + (cost of capital × days in transit) + rework allowance ] ÷ good parts received

Two of those terms are the ones most often left out, and both are real money.

Cost of capital while the goods are in transit. Sea freight from Asia to Europe or North America is planned in weeks, not days. Money spent on parts that are on a vessel is money not available for anything else, and at any realistic cost of capital that is a genuine line — small per part, but it is the term that makes air freight look less expensive than it appears when you compare freight quotes alone.

The allowance for the second shipment. If the first batch fails inspection, the cost is not the value of the failed parts. It is the failed parts, plus a second production run, plus a second freight charge at whatever the rate is by then, plus the delay. Buyers who have been through it once build a percentage into the landed cost; buyers who have not, do not, and then discover that the cheapest quote was the most expensive purchase.

One caution on the duty line, because it is where DDP quotes most often go wrong: the duty base is not the same everywhere. The EU assesses duty on a value that includes international freight and insurance; the United States generally assesses it on the goods value alone. A DDP price that applies one convention in the other country is wrong by the amount of the freight, and on a light, high-value consignment that is not a rounding error.

What We Quote, and What We Refuse to Guess

Our own position, stated so that you can hold us to it: we quote all four terms — EXW, FOB, CIF and DDP — and the quote comes back within 24 hours of drawings, material and quantity. Many suppliers stop at FOB. The four-term comparison is worth asking for by name, because the gap between them tells you more about a supplier's logistics than any brochure.

What we will not do is put a DDP figure on a page without stating its assumptions. A DDP price needs four statements attached: the HS code used, the destination door, whether duty and VAT are included or excluded, and what happens if customs reclassifies. A DDP number without those four is not a price; it is a guess with a currency symbol in front of it.

And one honest limit. We are a manufacturer, not a customs broker. On DDP we work through a forwarder, and the forwarder's name and the terms they apply are part of what you should ask for — from us, and from anyone else quoting you DDP.
