Customs Duty Calculator for USA

The math behind this customs duty calculator is simple — amount × rate — but the right United States rate is what makes the number useful. Enter both values and the result appears in US Dollar immediately. Enter the customs duty rate for United States as a plain percentage (15 means 15%, not 0.15).

   Adjust inputs and compare scenarios: re-run with a rate one point higher or lower to see how the US Dollar figure for United States moves.

• 1

  United States publishes customs duty figures in US Dollar, revised periodically — enter the rate currently in force for your case in United States rather than an older stored figure so the result matches the official calculation.

• 2

  When comparing two options for United States, run both through this customs duty with the same rate and the same US Dollar basis; then the difference you see reflects the options themselves rather than an inconsistency between the two inputs.

• 3

  Keep the customs duty amount and rate for United States on one period and one basis — monthly US Dollar figures with an annual rate, or gross with net, give a number that is arithmetically right but misleading in practice.

• Rates in United States move — annually, or with each fiscal announcement — and a Customs Duty result computed from last year's figure misleads budgets and quotes alike. Re-enter the current rate whenever the underlying number changes.

• Customs duty is charged on the CIF value — goods plus insurance plus freight — not the invoice alone: entering the bare US Dollar price understates the United States duty. Add shipping and insurance to the base before applying the rate.
