Landed Cost Guide for Ecommerce Brands

The arithmetic of landed cost is trivial. The hard parts are the two nobody writes down: which costs belong in the number, and how a cost that arrived for a whole shipment is divided between the products inside it. Those choices decide which SKUs look profitable — and they are choices, not calculations.

The definition and the per-unit sum are covered in what landed cost is. This guide starts where that ends: allocation, the components that go missing, why two quotes are rarely comparable, how duty is determined, and a worksheet you can copy.

The formula, and the two questions it hides

Landed cost per unit = (goods + origin charges + main carriage + insurance + duty + clearance + destination handling + inland transport + other direct costs) ÷ units

Every term after "goods" is either a shared cost needing allocation, or a cost sized by an earlier sourcing decision.

Two things make one shipment produce different unit costs in two competent spreadsheets. Scope: whether storage, testing, FX spread, financing and a returns provision are in or out. Allocation: whether a container’s freight is split evenly across units, or by weight, volume or value. Neither has one right answer for every business, but each has one for a given cost.

Landed cost is not customs value

These two get conflated constantly, and they are built for different purposes. Landed cost is a management number: what a unit really costs you, delivered and ready to sell. Customs value is a legal one, with prescribed rules.

Customs value

The value of imported goods determined under the WTO Customs Valuation Agreement, which the EU applies. It is the basis for ad valorem customs duty, for VAT on imported goods, and for trade statistics.

The European Commission sets out the mechanics plainly. The primary method is transaction value — the price actually paid or payable when goods are sold for export to the customs territory of the Union — covering about 95% of EU trade. Costs the buyer bore that the price does not contain must be added: commission and brokerage, containers, assists (goods or services the buyer supplied free or cheaply for producing the goods), royalties and licence fees paid as a condition of sale, resale proceeds accruing to the seller, and transport up to the point of entry. Explicitly not included: transport after that point, interest, the import duties and taxes levied by reason of the import, post-entry assembly or maintenance, and buying commission. Where transaction value cannot be used, five secondary methods apply in a prescribed order.

Two consequences follow. First, your landed cost includes things customs value excludes — the duty itself, the haulage from the port, storage, financing — so the two should never match, and a spreadsheet where they do has a mistake in it. Second, less obviously: because transport up to the point of entry sits inside customs value, cutting freight also cuts duty. A packaging change that reduces cubic volume reduces the freight bill and the duty computed on it — invisible when freight and duty live in separate tabs.

Allocation: the choice that decides which SKU looks profitable

A shipment does not arrive per SKU. Freight, insurance, terminal handling, brokerage and inland transport arrive as single figures for the whole consignment, and something has to divide them. Four bases are common, all defensible, all giving different answers.

The rule that resolves it: allocate on the driver. Ocean freight is bought with space, so volume is honest. Air freight is bought on chargeable weight, so weight is. Insurance follows value. Duty is never allocated — it belongs to a specific tariff line at a specific rate, per SKU. Allocation by value is the commonest choice because goods value is already on the invoice, and the most systematically misleading.

The size of the effect. Illustrative shipment, two SKUs, figures invented to keep the arithmetic legible: SKU A is 500 units of a bulky item at 6.00 each, occupying 18 m³. SKU B is 1,500 units of a small item at 30.00 each, occupying 2 m³. Shared cost to allocate: 4,000.

Illustrative figures. Nothing changed between the rows but the convention, and SKU A’s freight burden moves from 0.50 to 7.20 a unit — a fourteen-fold range on a 6.00 product. By value, SKU A looks healthy and SKU B weak; by volume, which is what the container was sold on, it is the other way round.

Every component, including the ones that go missing

The worksheet below has every line. These are the ones that disappear.

Before it leaves

• Tooling, moulds and patterns — amortised over the units you expect to sell, not all charged to the first order and not forgotten either.
• Sampling rounds and the couriers that carry them: individually small, collectively not.
• Packaging, labels, hangtags and inserts, where they are quoted separately.
• Export packing and pallets. Volume added here is a freight cost wearing a packaging label.
• Origin haulage, export clearance and origin port charges — inside the seller’s price under some delivery terms, not others.

On the way

• Surcharges attached to the freight rate — fuel, currency adjustment, peak season, congestion. Ask what the quote excludes.
• Cargo insurance at a stated level of cover. A premium is only comparable against a premium for the same cover.
• Transhipment or re-handling, where the routing has one.

After it arrives

• Destination terminal handling and port charges, not in the freight rate even though they arrive alongside it.
• Brokerage per declaration, plus a charge per extra tariff line on some quotes.
• Import VAT on the customs value plus duty — a cost or a timing difference, depending on your VAT position.
• Inspection charges when a consignment is selected for a check. The right provision is a probability, not zero.
• Demurrage and detention exposure: free time comes from the carrier contract, the risk from how fast you really clear.
• Inland transport, unloading and put-away, then storage until the goods sell — scaling with how wrong the forecast was.

The costs that are not transport at all

• Testing, certification and documentation, required by the destination market rather than the supplier — see EU manufacturing compliance. Usually per style, so amortise honestly.
• The FX spread between your bank’s rate and the reference rate: real on every payment, invisible because it is never a line item.
• Payment costs — wires, letters of credit, platform fees.
• The financing cost of a deposit paid months before the goods arrive: your cash, outstanding, at your own cost of money.
• A provision for returns, damage, rework and disposal. No supplier can give you this; your own history can.

Incoterms: what a quote already contains

The commonest cause of a wrong sourcing decision is comparing two prices that cover different journeys. The ICC publishes eleven Incoterms rules — used in trade contracts since 1936 and updated for Incoterms 2020 — allocating the tasks, costs and risks of delivering goods between seller and buyer. In the 2020 edition every cost belonging to a rule is collected at article A9/B9, so the full list for the term you are quoting under reads in one place.

UK customs guidance groups them as seven rules for any mode or modes of transport — EXW, FCA, CPT, CIP, DAP, DPU and DDP — and four reserved for sea and inland waterway transport: FAS, FOB, CFR and CIF.

So an EXW quote and a DDP quote are not two prices for the same thing, and ranking them as numbers is meaningless. Pick one term, add the missing steps to every quote until they reach the same physical point, then compare. Normalise to the term that matches where your own responsibility starts — normalising to DDP when you import the goods yourself hides costs you will pay.

One nuance worth holding onto: UK customs guidance is explicit that using a particular Incoterm does not restrict which customs valuation method applies. The delivery term allocates tasks and costs between two parties. It is not a valuation, and buying DDP does not stop duty being a cost inside the price you paid.

Duty: classification, origin and value

Duty is not a property of a country or a supplier. The European Commission is direct that the duties payable on a product — and related requirements such as import or export certificates — depend on its tariff classification, and that tariff treatment is decided by classification together with customs value and origin. Three inputs, and a sourcing decision can move all three.

Classification is defined in the Union Customs Code. The Combined Nomenclature is the EU’s eight-digit coding system, built on the World Customs Organization’s Harmonised System, and TARIC integrates the tariff, commercial and agricultural measures applying to a code. That is where a rate comes from: the code for your goods, in the destination market’s tariff. A rate a supplier quotes is a starting point for your own check, not an answer.

Origin is what the Commission calls the "economic nationality" of goods — where they are deemed produced, not where they shipped from. Non-preferential origin supports most-favoured-nation treatment and underpins instruments like anti-dumping and countervailing duties, safeguards and quotas. Preferential origin, under a trade agreement or unilateral scheme, can mean a lower or zero rate where the product meets that arrangement’s rules and the proof of origin exists. Assembling in a country is not the same as originating there.

Where the answer has to be certain in advance, it can be. A Binding Tariff Information decision is a legal decision from an EU customs authority on a product’s classification, generally valid for three years and binding on all EU customs administrations and on the holder; Binding Origin Information does the equivalent for origin. Where duty exposure is large, that certainty is cheap.

Lawful levers exist, and they are all design-time levers — the composition, construction and configuration of the product, settled before a specification is frozen. Tariff engineering strategies covers them. What does not exist is a way to declare something other than what it is.

Comparing two origins properly

Comparing countries on factory price is the same error as comparing quotes on different terms, one level up. A real comparison has five axes.

Working capital is the axis most often left out, and on a growing brand it can dominate the rest. A route cheaper per unit but with weeks more transit and a larger deposit ties up more cash for longer — and no article can give you that cost, because it is your cost of money times your days outstanding. The faster mode is dearer per unit and cheaper in cash tied up: a genuine trade. Sourcing from Vietnam works one region through these axes.

Two worked examples with opposite shapes

Example 1 — light and high-value, where duty dominates

Illustrative: 1,000 units of a small, light, high-value accessory, bought FOB at 40.00 a unit, air freighted at 220 kg chargeable weight, with an assumed duty rate of 8%.

The unit lands about 14% above the factory price, and the shape of that gap is the point: duty at 3,351.20 is nearly double the air freight bill. One percentage point of duty is worth 418.90, about 0.42 a unit. Ten per cent off the freight rate saves 176 — plus about 14 of duty, since that freight sits inside the customs value — roughly 0.19 a unit. Here classification and origin work beats freight negotiation twice over, and only before the specification is frozen.

Example 2 — bulky and low-value, where freight dominates

Illustrative: 2,000 units of a bulky homeware item, bought FOB at 6.00 a unit, shipped by sea at 24 m³, with an assumed duty rate of 4%.

The same formula, the opposite lever. This unit lands about 45% above the factory price, and the transport side — freight, terminal handling, inland transport, unloading — comes to 4,560 against 626.20 of duty, more than seven to one. A point of duty is worth 0.08 a unit. A pack redesign shipping the item 15% smaller saves roughly 540 of freight and 22 of duty with it, near 0.28 a unit: three and a half times a full point of duty relief. Here the money is in cartons, cube and container utilisation.

Illustrative figures throughout. The transferable finding is the shape, not the numbers: on a light, high-value product duty is the lever; on a bulky, low-value one, volume is.

The landed cost worksheet

Copy this as your sheet. The two right-hand columns matter more than the amounts: the basis stops a shared cost being divided on the wrong driver, and the source says which lines are quoted, which estimated and which your own policy.

Mark every amount quoted, estimated or policy. A landed cost built mostly from estimates is a hypothesis, and should be labelled as one when it chooses a supplier.

When landed cost is not the answer

Landed cost is one input to a decision, not the decision. It regularly points one way while lead time, minimum order quantity, quality risk or cash flow point another.

1. Normalise before you trade anything off

   Same quantity, specification, delivery term and currency, all prices still valid. Numbers that are not comparable cannot be traded off, only argued about.

2. Separate quoted from estimated

   If the gap between two options is smaller than the uncertainty in your estimates, you do not have a decision — you have a reason to get another quote.

3. Price the lead time

   Convert extra weeks into cash tied up at your cost of money, and into the odds of missing a season. A cheaper unit arriving after the selling window has a landed cost that is correct and irrelevant.

4. Price the minimum order quantity

   A lower unit cost at three times the quantity is only cheaper on the units you sell. Add storage and a markdown assumption for the rest, and the ranking often inverts.

5. Price the quality risk

   Probability of a rework or a rejected lot times what it costs is a real line, even as an estimate — see reducing supplier quality risk.

6. Decide against the constraint that binds

   Cash, date, quality or price — name which binds before you look at the numbers, so the numbers do not silently name it for you.

• Before you accept a landed cost number
• Every quote is normalised to one delivery term, one quantity and one currency.
• Duty is per SKU, from your own classification and origin — not allocated, not a supplier’s estimate.
• Shared costs sit on the driver that caused them, and you can name that driver.
• Freight comes from a current quote for this shipment, with validity date and excluded surcharges named.
• The destination-side lines exist: terminal handling, brokerage, inland transport, put-away, storage.
• FX, payment fees and the deposit’s financing cost are in the sheet, not in overhead.
• A returns and damage provision is present, with your own rate behind it.

How Library of Trade approaches it

We treat landed cost as the number the brief targets, not a figure produced at the end. AI structures and compares at scale — normalising quotes to one term, holding materials, freight and duty inputs against the same specification, and showing where a decision has just moved the delivered cost. Our expert team then evaluates, negotiates and decides, and supplier partners execute. You contract directly with your suppliers; we are not a marketplace and not a directory.

It works as one view because of the interaction, not the arithmetic: material weight moves freight, freight moves customs value, customs value moves duty, and factory location moves all three. The complete guide to product sourcing walks the stages where those decisions are taken.
