Landed cost is the total cost required to place a sellable unit at the location where the business can use it. Supplier unit price is only the first layer. Freight, insurance, duties, brokerage, terminal and carrier fees, receiving labor, prep, damage, shortages, financing, and disposal can all change whether an apparently attractive wholesale buy produces margin.
For imports, begin with current government guidance. U.S. Customs and Border Protection's importing overview explains the importer's responsibility for reasonable care and compliance even when a broker assists. Translate “supplier handles customs” into named parties, entry records, and a verified delivery rule.
Choose one cost boundary for every quote
Define where the comparison ends: seller dock, port, buyer dock, fulfillment center, or shelf-ready stock. Convert every offer to that point. A destination-delivered quote and a factory pickup quote are not competing prices until missing transport, export, import, and delivery work is filled in. Use the official ICC Incoterms rules when a contract incorporates one.
| Layer | Inputs | Allocation question |
|---|---|---|
| Product | Unit price, samples, tooling, packaging | One-time or recurring? |
| Movement | Pickup, linehaul, ocean or air, insurance | Unit, weight, cube, or value? |
| Border | Duty, tax, broker, exam, terminal fees | Which classification and value? |
| Destination | Drayage, appointment, unloading, receiving | Dock or accepted stock? |
| Sellability | Prep, damage, shortage, returns | How many units can sell? |
| Capital | Deposit, credit, currency, dwell time | How long is cash committed? |
Build the numerator from documented cost lines
Keep quoted, estimated, and unknown amounts separate. Record classification, country of origin, customs-value basis, currency rate, and date checked. CBP's guidance on duties and processing fees is useful orientation, but commercial importers should verify treatment for the actual merchandise.
- Supplier: goods, packaging changes, inspection, documentation, payment, and setup.
- Origin: pickup, export handling, terminal, clearance, and consolidation.
- Movement: freight, fuel, security, insurance, and peak charges.
- Import: duties, taxes, brokerage, exams, storage, and delay exposure.
- Destination: final mile, appointments, receiving, labeling, and prep.
- Quality: shortage, damage, rejection, return, disposal, and recovery value.
Divide by accepted sellable units
If 10,000 units are ordered, 9,700 arrive, and 9,550 pass inspection, shipment-level cost belongs across 9,550 sellable units. Preserve ordered, shipped, received, accepted, and sellable quantities separately. That shows whether variance came from supplier fill, transit, receiving, or quality.
Match allocation to the cost driver. Freight may follow weight or cube, insurance declared value, and handling cases or pallets. A unit split is acceptable for similar goods but can shift cost unfairly between bulky low-value and small high-value items.
Translate Incoterms into cost owners
Incoterms allocate specified delivery tasks, cost, and risk; they do not set price, title, quality, payment, or remedies. The ICC checklist emphasizes rule, precise named place, and version. Build a responsibility matrix showing who books, pays, clears, insures, hands off, and documents each leg.
The freight and consolidation guide turns that matrix into shipment decisions. Included cost still belongs in the comparison because it defines the service and risk boundary.
Add time, defects, and uncertainty
Map deposit, balance, transit, acceptance, sale, and customer settlement. Keep financing separate from merchandise margin so the team can compare cash purchases with Net 7, Net 15, and Net 30. Run base and downside cases for freight, delay, currency, shortage, rejection, and price pressure.
Reconcile estimate to actual
Retain the RFQ, quote, order, invoices, freight bills, import records, receiving report, and exceptions under one shipment or lot ID. Replace estimates with actuals without deleting assumptions. Variance reveals which supplier, route, packaging, and buffer needs adjustment.
Start with a complete RFQ cost table. A landed-cost worksheet cannot recover information that the buyer never requested or the supplier never qualified.
