What is landed cost?

Landed cost is the number a buyer should compare when supplier quotes do not cover the same cost base. The invoice price is only one part of it. Depending on the category, landed cost can include freight, terminal handling, insurance, customs, duties, surcharges, currency conversion, and the buyer-side charges that appear after the goods move.

The practical test is simple: if the buyer must pay it to receive usable goods at the agreed destination, it belongs in the comparison. If one supplier bundles that cost and another leaves it out, the headline prices are not comparable yet.

That is why landed cost matters in freight. A CIF quote, an FOB quote, and an EXW quote can all describe the same shipment while covering different spans of the journey. Ranking those raw totals would reward the quote that excluded the most work, not the supplier with the lowest true cost.

The July 2026 PAIR-20 landed-cost task tested exactly that pattern. In the run, all four platforms saw that the headline TranStar quote was incomplete and rebuilt a landed-cost stack under the structured brief. None reached the EUR7,940 case answer. ChatGPT and Gemini were EUR112 low, Claude was EUR87 low, and Copilot received a partial verdict because its table and prose contradicted each other.

Landed cost is a scope question before it is a math question. First ask what each quote includes and excludes. Only then does the addition mean anything.

The missing lines are often the decision. A low freight rate can become an expensive option once insurance, handling, customs, and surcharge assumptions are added back.

AI can help build the stack, but the stack needs review. In the July run, the models made the work more visible and still missed the final number. For a working procurement team, the useful output is not just the total. It is the line-by-line map of what was counted.
