About Customs Duty And IGST Calculator

Import charges cascade: basic duty on assessable value, a surcharge on that duty, then integrated tax on value plus both. Because the integrated tax base includes the duty, the effective burden is higher than the sum of the rates.

Formula

Import duty stack

BCD = V×r; surcharge = BCD×s; IGST = (V + BCD + surcharge)×i

Worked example

With the default values below, Customs Duty And IGST Calculator returns Total Duties And Taxes of $309,800.00. Change any input above and every figure here is recalculated in your browser.
