Whenever a foreign producer is selling a product like steel at a lower price than domestic producers, then dumping is being practiced and must be corrected.

Dumping refers specifically to the act of exporting a product at a price lower than its normal value, particularly the price in the domestic market of the exporting country. It's not merely about selling at lower prices than domestic producers but involves a specific comparison to home market prices or production costs. Anti-dumping measures or corrections are applied only if this practice causes or threatens to cause material injury to a domestic industry.
