The invoice price is the smallest part of what a container costs. Six lines sit between the factory gate and your warehouse, and five of them are predictable before you order.
The six lines
Goods, freight, insurance, duty, port and clearance charges, and inland delivery. Then the seventh, which is not a line item until it happens: the cost of defects and the cost of capital tied up in transit.
Most buyers calculate the first three and estimate the rest. The estimate is usually low by a margin that exceeds the entire negotiation.
Duty is a specification decision
Duty is set by the material and the origin, not by the price. A change in construction can move a product between tariff lines, and the saving can exceed the material cost difference.
This is worth a conversation with a customs broker before the specification is fixed, not after.
The cost of transit time
Thirty-five days at sea is thirty-five days of working capital, plus the risk of a season starting without stock. Air freight is expensive per kilo and sometimes cheaper per week of lost sales.
The calculation is specific to your margin and your season. There is no general answer, and any supplier who offers one is simplifying.
Building a repeatable model
One spreadsheet, six lines, updated with the actual invoice after each shipment. After three shipments the estimates become reliable and the negotiation moves to the lines that actually matter.
A worked structure
Take a container value of 100. Freight to a European port is commonly 8-15 % of that today, insurance under 1 %, duty between 0 and 12 % depending on the tariff line, and port plus clearance 2-4 %. Inland delivery adds 1-3 %. The total lands somewhere between 115 and 135, and the gap between the low and high end is larger than most negotiated discounts.
That is the argument for spending an hour with a customs broker before the specification is fixed. The tariff line is decided by the material and the construction, and it is much easier to change on paper than after the tooling.
The two costs nobody puts in the model
The first is capital tied up in transit: thirty-five days at sea is thirty-five days of cash, and for a business with a 30 % margin that is a real number. The second is the cost of a stock-out in the launch window, which is usually larger than the freight difference between sea and air.
Both are specific to your business, which is why a supplier cannot advise on them. What a supplier can do is give you a lead time you can plan against, and that is worth more than a small freight saving.
Currency, payment terms and the cash cycle
Landed cost is usually calculated at the invoice rate, which is not the rate you pay. If the order is in dollars and your revenue is in euros, the exposure runs from the PO to the payment, often three months. That is a real cost and it belongs in the model.
Payment terms move it further. A 30 % deposit plus 70 % against documents means most of the cash leaves before the goods do. An open account moves it after, at a price. Neither is free, and the difference is a financing decision that should be compared explicitly.
Reviewing the model after each shipment
Replace the estimates with the actual invoices, then look at which line was furthest from the estimate. After three shipments the model is reliable, and the negotiation moves to the lines that actually vary rather than the one that is easiest to discuss.
| Line | Typical share of goods value | What moves it |
|---|---|---|
| Goods | 100 % | The only line most buyers negotiate |
| Freight | 8-15 % | Volume and loading efficiency |
| Insurance | under 1 % | Value and route |
| Duty | 0-12 % | Tariff line, which is a specification decision |
| Port and clearance | 2-4 % | Fixed per shipment |
| Inland delivery | 1-3 % | Distance and pallet configuration |

Questions buyers ask before ordering
Can you quote against a specification I write myself?
Yes. Send it as written and we will come back with a line-by-line response, including where we would deviate and why. That is more useful than a price against a document we have silently reinterpreted.
What do you need to start?
End use, quantity per colour, destination market and the date you need the goods. With those four we can quote; without them we are guessing.
Failure modes worth a clause in the purchase order
Claims rarely come from a batch that was obviously wrong. They come from a abrasion figure that sat inside the quoted band and outside what the product needed.
| Failure | What triggers it | Test to demand on the production lot |
|---|---|---|
| Colour transfer | Excess pigment on the surface and insufficient topcoat. | Peel strength — ISO 2411; acceptance >= 6 N/50 mm |
| Hydrolysis | Ester-based PU plus moisture plus heat. It is a chemistry problem, not a coating weight problem. | Hydrolysis (ageing) — 70 C / 95 % RH, 7 days; acceptance no tackiness, >= 80 % peel retained |
The other two, with acceptance numbers attached, are in the full failure analysis for PU leather. A supplier who cannot name the mode he sees most often is describing a catalogue, not a process.
Seven lines that turn a quotation into a specification
Most post-delivery arguments are not about quality. They are about a document that never said which figure would be measured, on which instrument, at whose cost.
- Cold flex: -20 C, 30 000 cycles is the market band. Fix the figure you will test at goods-in, and the instrument you will test it with.
- Surface finish (release paper / cast / embossed): fix the value per shipment, and state who pays for the re-test if a lot lands outside it.
- Colour fastness to rubbing: >= grade 4 is not an answer on its own. Ask for the last three lots’ actual readings and the spread behind them.
- Thickness: agree the test method with the number. Two labs, two methods, two answers, one argument.
- Deviation rule: anything outside the agreed bands is reported before shipment, not after arrival.
- Packing and marking: shipping mark, roll or carton count and the tolerance on quantity, since a short shipment is a claim too.
- Who inspects: third-party, in-house or none, decided in advance, with the AQL level written down.
The same question, asked of basswood
The two lines fail differently, so the wording that protects you differs too. On basswood the recurring modes are these, caught with a different test.
| Failure | What triggers it | Test to demand on the production lot |
|---|---|---|
| basswood: Warping and bowing | Moisture content outside 8-12 %, or slats packed before equalising. | Moisture content — oven-dry method / pin meter; acceptance 8-12 % |
| basswood: Colour mismatch between slats | Stain bath drift and mixing slats from two production days. | Warp — 48 h at 23 C / 50 % RH; acceptance <= 1.5 mm per 1 m |
