An anti-dumping duty is an import restriction tool that can be imposed on a good to stop its import from a particular country or in a particular product category. This duty can be levied on a country for a specific good when the country is suspected of exporting that good at a cheaper rate than what it is sold for in its local market.
A dumping claim is followed by an anti-dumping investigation. Dumping may negatively impact the domestic producers because they are bound to compete with the lower prices of the imported good. In the wake of growing protectionist sentiments amongst countries, Anti-Dumping duties stand as a powerful tool.
