Use the evidence and practical questions in this article to test your own assumptions. Any worked examples use hypothetical inputs.
Unit price is only the starting point
Landed cost is a planning view of what it takes to bring goods to the intended usable location. Define that location before comparing suppliers: a port, warehouse and retail shelf are different endpoints. Include product cost, freight, insurance where applicable, customs-related charges, handling and inland delivery without double-counting items already included in a quote. CBP explains that duty treatment depends on product classification and other transaction facts. Do not substitute an old percentage for a current review. This worksheet is a business budgeting example, not a customs valuation ruling or a tariff quote for a particular shipment.
A hypothetical shipment calculation
Assume an order costs $10,000 for goods, $1,200 for freight, $200 for insurance, $900 for a hypothetical customs-and-broker allowance and $700 for handling and delivery. The planning total is $13,000. If 1,000 saleable units arrive, the allocated cost is $13 per unit. The $900 allowance is an invented input, not a stated US duty rate. Replace every input with the actual quotation and current classification-based advice. If only 950 units are saleable, dividing the same total by 950 raises the effective unit cost to approximately $13.68 before any additional loss-related expense.
Add time and reconcile actual spending
A landed-cost worksheet should show when cash leaves and when inventory becomes available, not only the final total. A slower shipment can tie up cash longer and create stockout or storage costs. Keep those operating effects visible rather than hiding them inside an unexplained margin adjustment. After delivery, replace estimates with actual invoices and investigate differences. Use the result to update pricing, reorder quantities and the next supplier comparison. A hypothetical low unit-price offer may be unattractive once freight, rejects and delivery timing are included. The useful decision compares complete routes to usable inventory on the same basis.
- Define the destination and avoid duplicate cost lines.
- Allocate across saleable units, not merely ordered units.
- Reconcile estimates with actual charges and inventory timing.

Frequently asked questions
Is the example customs allowance a real tariff rate?
No. It is a hypothetical budgeting input that must be replaced with transaction-specific current information.
Should damaged units be counted as saleable?
Use the units actually available for the intended sale and account separately for damage and recovery.
