Import duty calculator
Estimate the mechanics of import duty — honestly. We show how the calculation works and where real rates come from. We never invent tariff rates.
How duty actually works
Import duty equals customs value times the applicable tariff rate for the exact HS classification - plus any anti-dumping, countervailing or safeguard duties. The rate depends on the precise HS code (8–10 digits), the country of origin, and applicable trade agreements.
We don't publish tariff rates until they're verified against official tariff sources. Use the interactive calculator for the mechanics, and the official tariff portals - EU Access2Markets, US HTS Search, UK Global Tariff - for the actual rates.
What the calculator estimates
- How customs value is derived from your declared goods value, freight and insurance.
- How the tariff rate interacts with the 8–10 digit national HS code and country of origin.
- Where anti-dumping, countervailing and safeguard duties can apply on top of the base rate.
- Why a rate from an unverified source is worse than no rate at all.
The interactive calculator walks through the mechanics step by step. For actual rates, always consult the official tariff portals below — or your customs broker.
