A border measure applied to imports of a product from an exporter, which imports are dumped and are causing injury to the domestic industry producing the like product, or to third countries' exporters of that product. Dumping takes place when a product is introduced into the commerce of an importing country at less than its normal value, generally where the export price of the product is less than the comparable price, in the ordinary course of trade, for the like product when destined for consumption in the exporting country. Anti-dumping measures may take the form of anti-dumping duties, or of price undertakings by the exporting firms.
