The invoice price is the smallest part of what you actually pay. Landed cost is the number that decides whether a deal makes money.
| Component | Notes |
|---|---|
| Product price (FOB) | What the supplier invoices |
| Freight | Ocean or air carriage to the destination port |
| Insurance | Marine cover on the consignment |
| Assessable value | Usually CIF plus a nominal landing charge |
| Basic customs duty | Driven by the HS code and country of origin |
| Surcharge | Commonly a percentage of the duty itself |
| IGST or VAT | On the duty-inclusive value; often recoverable |
| Port and handling | Terminal charges, clearance, documentation |
| Inland transport | Port to warehouse |
Treating recoverable tax as cost. If you can claim IGST as input credit it affects cash flow, not margin. Mixing the two either kills viable deals or flatters bad ones.
Duty rate, surcharge, applicable cess and any trade remedy all follow the classification. Change the code and the whole landed cost moves. See our customs duty guide for how the components stack.
Landed cost is not a difficult calculation; it is a difficult inventory of components. Almost everyone gets the product price, the main freight and the basic duty. The gap between a rough model and a reliable one is the second tier — terminal handling at both ends, inland legs, demurrage risk, the financing cost of payment terms, currency exposure, and the portion of tax that is genuinely a cost rather than a credit.
| Layer | Frequently omitted | Rough materiality |
|---|---|---|
| Ex-works price | No | The anchor |
| Export packing | Yes | Material on fragile or long-transit goods |
| Inland to port at origin | Sometimes | Large where the supplier clears far inland |
| Main freight | No | Often the second largest line |
| Insurance | Sometimes | Small, until there is a claim |
| Terminal handling | Yes | Consistently underestimated at both ends |
| Customs duty | No | Depends entirely on the tariff line |
| Creditable tax | Misclassified | Cash flow, not cost, for registered buyers |
| Inland at destination | Yes | Frequently larger than the ocean leg on short lanes |
| Demurrage allowance | Yes | Zero until a query, then substantial |
| Financing the terms | Yes | Cost of capital times days outstanding |
Choosing a different delivery term does not make the cost disappear; it moves who arranges and pays for it. What it does change is who is better placed to buy each component, and that genuinely affects the total. A supplier with weekly volume on a lane usually buys freight more cheaply than an occasional buyer does. A buyer with an established brokerage relationship usually clears more cheaply than a foreign seller could. Allocating each component to whoever buys it best is the actual optimisation.
A landed-cost model earns its keep by being maintained rather than by being sophisticated. Keep the components separate so a change in freight or duty can be updated without rebuilding. Record the assumption and its date next to each figure. Run the sensitivity on the two or three lines that actually move — freight, duty and currency — rather than on everything. And compare origins on delivered cost into your own facility, because that is the only comparison that decides anything.
Every duty figure in the model is attached to a tariff line. If the classification is uncertain, the landed cost is uncertain by the same amount, and no amount of care elsewhere compensates.
Everything above is a framework, and a framework is only worth what it survives contact with. The useful discipline is to test each assumption against what consignments actually did, because customs data is one of the few commercial sources where the underlying event — goods crossing a border — physically happened and was documented under legal obligation at the time.
Fix the tariff line before anything else. Every filter, every duty figure and every comparison downstream depends on it.

Learn more ›Two failure modes account for most wrong conclusions drawn from trade data, and both are easy to avoid once named. The first is reading the incomplete tail of a series as a decline — authorities publish on a lag and revise afterwards, so the last one or two periods will fill in after you look. The second is reading a value movement as a demand movement, when declared value can move because volume moved, because unit price moved, or because the product mix inside a tariff line changed.
Customs data covers goods that crossed a border. It does not cover services, domestic trade, margin, contract terms or intent. Treat it as a dated, quantified observation to corroborate — not as a conclusion that arrives finished.
The difference between teams that get value out of trade data and teams that ran one interesting project is almost never analytical sophistication. It is whether the work became a routine. A saved query reviewed weekly, a short written note against each counterparty you assessed, and a standing habit of checking the period stamp before quoting a figure will out-perform an elaborate one-off study within a quarter, because markets move and a study does not.
The second habit worth building is writing down not just what you concluded but why and when. Records get revised, prices move, and counterparties change behaviour. Six months later nobody remembers whether a supplier was rejected on volume, on price band or on timing, and without that note the assessment simply gets repeated from scratch. A one-line rationale is what converts a list into institutional knowledge, and it costs seconds at the point where the thinking has already been done.
Finally, be explicit with colleagues about the confidence attached to any figure you circulate. A declared value from a complete period, controlled for origin and unit, is strong evidence. The same figure pulled from an incomplete recent period, averaged across a whole chapter, is barely evidence at all — and the two look identical once they are in a slide. Saying which one you have is what keeps trade data credible inside an organisation over time.
For a registered business that can credit it, it affects cash flow rather than cost. For anyone who cannot claim the credit it is a real cost, and the difference is often large enough to change a sourcing decision.
Yes, if the payment terms are material. Ninety days of working capital has a price even when nobody invoices you for it.
Normalise both to delivered cost at your own facility. Comparing an ex-works price against a CIF price is not a comparison at all.
Destination-side terminal handling and the inland leg. On short ocean lanes they can exceed the freight everyone was negotiating over.
Markets refresh on their customs authority's own release cycle — monthly for most, 45 to 60 days for a few. The most recent one or two periods are always still filling in, so exclude them when you are reading a trend rather than treating the gap as a decline.
Yes. Give us the HS code or a product description and the market you care about, and we will return a sample of live customs records filed against it.

The next questions this one usually raises are covered in Incoterms explained, Indian import duty, explained and Air freight or sea freight. Each picks up where this article stops, and together they cover the sequence a consignment actually goes through — classification and duty before anything moves, documentation and payment while it moves, and verification of the counterparty before any of it is committed to. Reading them in that order is usually more useful than reading them by topic.
