• 1

  United Kingdom publishes import duty figures in Pound Sterling, revised periodically — enter the rate currently in force for your case in United Kingdom rather than an older stored figure so the result matches the official calculation.

• 2

  Treat the computed Pound Sterling amount as the base figure for United Kingdom: any additional local fees, deductions, or rounding rules that apply to your situation must be added separately, so the number you rely on stays honest and complete.

• 3

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

• Rates in United Kingdom move — annually, or with each fiscal announcement — and a Import 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 Pound Sterling price understates the United Kingdom duty. Add shipping and insurance to the base before applying the rate.
