Import duty is estimated by multiplying customs value by the base duty rate, then adding any additional tariff rate, tax or VAT, brokerage, handling, and other fees. TariffCatalog uses manual inputs so rates can be verified against official sources.
Total import cost = customs value + base duty + additional tariff + VAT or tax + brokerage + handling + other fees. The tax basis can be customs value only, customs value plus duty, or customs value plus duty plus additional tariff.
Use this calculator after you know the HS code candidate, origin, customs value basis, duty rate, additional tariff rate, and destination tax approach.
