Landed Cost Calculation: What Buyers Need to Include

Landed cost = purchase price + ocean freight + customs duty + port fees + insurance + inland freight + brokerage. Here is how to calculate it and compare sourcing options on a true cost basis.

Landed cost equals FOB purchase price plus ocean or air freight plus customs duty plus port handling fees plus import bond or broker fee plus insurance plus inland freight to the warehouse. For a $10,000 FOB China shipment with $800 ocean freight, 12% duty, $250 port fees, $175 broker fee, $45 insurance, and $320 inland freight, landed cost is $12,790. On a 1,000 unit buy, the part that looked like $10.00 actually costs $12.79 at your dock. That difference matters because sourcing decisions made on invoice price alone often look cheap until the first container arrives. Landed cost is the real purchase price the plant has to absorb.

The key inputs are purchase value, HTS code, country of origin, freight mode, insurance, port charges, and inland freight. Duty rate is set by the Harmonized Tariff Schedule and can range from 0% to 25% or more depending on product and trade rules. Goods from China may also face Section 301 tariffs that add 7.5% to 25% on top of base duty. Freight rates should come from current broker or forwarder quotes, not a make or buy study from two years ago. Brokerage, port fees, and inland drayage are often available from prior import records and current lane quotes.

The most common mistake is using the wrong HTS classification or ignoring tariffs tied to country of origin. A one-digit classification miss can change duty materially. Another common error is freezing freight assumptions for too long. Ocean rates swung from roughly $1,500 per 40 foot container before 2020 to more than $20,000 in 2021 and 2022, then settled back lower, so stale freight assumptions can break a sourcing decision. Buyers also forget currency exposure. If the foreign currency strengthens 5%, the purchase price portion of landed cost rises 5% before the goods even ship.

Use landed cost to compare domestic and imported sourcing on the same basis. A supplier with a lower piece price may still be more expensive once duty, freight, and inland handling are included. The result should feed make or buy analysis, quote comparisons, and reorder planning. It also helps purchasing run sensitivity cases, such as what happens if freight doubles or a tariff is added. That is how landed cost turns from a finance cleanup exercise into a live sourcing tool.

Do not stop at border costs if you are choosing between supply options. Long transit lead times increase pipeline inventory, and imported parts may carry higher quality and disruption risk than domestic supply. Related metrics such as safety stock, inventory carrying cost, and supplier scorecard performance help show the full total-cost picture. Review landed cost whenever freight markets, tariff policy, or exchange rates move. A sourcing decision is only sound when the delivered cost math is current.
