Import Duty Calculator: assumptions and common mistakes
A useful estimate starts with the right inputs. Check the following assumptions and limits before applying the result to your situation.
- Enter the correct assessable value and tariff rates for the import. Exemptions, anti-dumping duties and other levy-specific bases are not automatically determined.
- Use the rate and eligibility rules that apply to your transaction. An example rate does not establish a tax liability or entitlement.
