Dumping: When Exporters Price Below Cost to Capture Markets

Dumping occurs when a foreign producer sells goods in an export market at prices below cost or below the home market price.

  • Dumping is selling exports below normal value — either below the home market price or below production cost

  • Anti-dumping duties counteract the price advantage by adding a tariff equal to the dumping margin
