Anti-dumping measures provide a remedy for domestic industries against unfairly priced imported goods. Dumping occurs when goods are exported at prices below normal value, i.e. lower than domestic sales prices. Anti-dumping duties equal to the dumping margin may be imposed if dumping causes material injury to a domestic industry. Smuggling refers to the illegal transportation of goods across borders and is not related to anti-dumping as it does not involve price discrimination but unlawful trade. While cheap imports are often mistakenly referred to as dumping, dumping has a specific legal definition requiring a price comparison to normal value.
