How to Use This Tool
Stack customs value, duty and import tax instead of applying every rate to the invoice alone. Duty and import tax may use different bases, so adding percentages to invoice value can understate cash due at the border.
Why Import Landed Cost needs more than a raw total
The model deliberately compounds tax after duty; replace the basis when the destination uses a different rule. For this page, the useful comparison is estimated landed subtotal, not whichever input happens to be largest. The Import Landed Cost result answers the decision in the heading and should not be reused as a score for a different workflow.
The exact Import Landed Cost formula
Subtotal equals goods plus freight plus insurance, multiplied by one plus duty and then one plus import tax. The visible fields are Goods value, Freight, Insurance, Duty rate and Import tax rate. For Import Landed Cost, read each printed unit before entry and make the values describe one transaction, cohort or reporting window. If those scopes differ, the displayed estimated landed subtotal may be arithmetically valid but operationally meaningless.
Interpreting estimated landed subtotal
Use the estimate for purchasing cash flow, then confirm classification and valuation with a broker or customs authority. The ten-percent comparison is deliberately narrow: it tests the influence of goods value and is neither a forecast nor a confidence interval. Preserve the values used, their dates and the resulting decision so a later reviewer can reproduce why Import Landed Cost supported the choice.
What this Import Landed Cost model leaves out
Brokerage, anti-dumping duties, de minimis rules and country-specific valuation are excluded. That is where Import Landed Cost stops being trustworthy. If an excluded factor could reverse estimated landed subtotal, extend the model explicitly or use the authoritative account system instead of hiding the factor inside an unexplained adjustment.
Evidence and independent verification
The reference reviewed for Import Landed Cost is U.S. CBP — Importing into the United States. U.S. CBP — Importing into the United States supports the named definition or rule but does not supply private values for estimated landed subtotal. Before acting on the result, reconcile the worked example with the relevant dashboard, invoice, export or measurement.
Private, reproducible calculation
Import Landed Cost runs its arithmetic in the current browser tab and requests no login or API key. That keeps the Import Landed Cost inputs away from the site's calculation server, while leaving the user responsible for detecting stale data or a changed platform rule. When an assumption changes, reopen U.S. CBP — Importing into the United States and rerun the saved Import Landed Cost scenario.
