Anti-Dumping Duty
Additional duty imposed when a country determines goods are being sold below fair market value. Stacks on top of MFN duty and applies only to specific products from specific origins.
Anti-dumping duty is levied after a formal investigation finds that imports are being sold below normal value in the importing country. It is product-specific and country-specific — it does not apply broadly.
ADD rates and orders are maintained by the EU Commission (TRON database), US Department of Commerce, and HMRC (Trade Remedies Authority) respectively. If your product is subject to ADD, the rate can be many times larger than the base MFN duty.
