This document discusses dumping and the conditions for imposing anti-dumping duties. It defines dumping as exporting a product at a lower price in a foreign market than in the domestic market. Dumping can have advantages like penetrating new markets, but also disadvantages like retaliation. Anti-dumping measures aim to counter the trade-distorting effects of dumping and include tariffs and import quotas. For a country to impose anti-dumping duties, there must be evidence of dumping, injury to a domestic industry, and a causal link between the dumping and injury. The effects of anti-dumping laws can be both positive in protecting domestic industries, and negative in creating trade barriers.
