Anti-Dumping Duty Calculator
Additional duty that can dwarf the base rate.
Duty rates and thresholds change with trade policy. These are planning estimates — the entry filed with customs decides the actual charge.

The measure adds 11.6% of the selling price. Check whether your specific producer has an individual rate — they are frequently lower than the country-wide residual rate.
How the Anti-Dumping Duty Calculator works
Anti-dumping duty is imposed when goods are found to be sold below fair value in a way that harms domestic producers. Rates can reach several hundred percent, which is enough to make an otherwise viable product completely unsellable — and it is applied on top of the normal duty.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
How high can anti-dumping duty be?
Far higher than ordinary duty. Rates of 20-100% are common and some cases exceed 300%. Because it applies to the same customs value as the base duty, it can multiply the total charge several times over.
How do I know if it applies?
By HS code, country of origin, and often the specific producer. Customs authorities publish current measures. Some producers have individual rates lower than the country-wide residual rate, so the exact factory matters.
Can I avoid it by buying from a different country?
Legitimately, yes — sourcing from a country not covered by the measure is a normal commercial response. Routing the same goods through a third country to disguise origin is circumvention and is actively investigated.
How long do these measures last?
Typically five years, subject to review and frequently extended. They can also be imposed provisionally during an investigation, sometimes retrospectively — which is a real risk if you are importing a product currently under investigation.
