Anti-Dumping Duty

Anti-Dumping Duty (ADD) is a protectionist tariff levied by an importing country on foreign goods that are determined to be priced below their fair market value—a practice known as dumping—to protect domestic industries from material injury. This duty is calculated to offset the margin of dumping, ensuring a level playing field in international trade as permitted under the World Trade Organization's (WTO) Anti-Dumping Agreement.
