dumping

Imagine a big foreign company that sells its washing machines for 800 dollars at home but ships them to your country and sells them for 400 — sometimes below what they cost to make. Local manufacturers, who cannot match that price, start to lose customers. To buyers it looks like a wonderful bargain; to the home industry it looks like an attack. Selling exports abroad at a price below the home-market price (or below cost) is what trade law calls dumping.

Dumping means a firm exports a product at a price lower than it charges in its own domestic market, or below its cost of production. Why would a company sell so cheaply? Several reasons: it may be unloading surplus output, it may be subsidised by its home government, it may simply face more competition abroad, or — the worst case — it may be 'predatory', deliberately pricing low to drive foreign competitors out of business so it can raise prices later once it dominates. Genuine predatory dumping is hard to pull off and rarer than accusations suggest, but the harm to a targeted domestic industry can be real while it lasts.

Because dumping is considered an unfair trade practice, World Trade Organization rules let an importing country investigate and, if it finds both dumping and resulting injury to a domestic industry, impose an 'anti-dumping duty' — essentially a tariff sized to offset the unfairly low price. The honest tension here is that consumers actually benefit from the low prices in the short run, so anti-dumping measures protect producers at consumers' expense. And the rules are easy to abuse: anti-dumping complaints are one of the most common tools countries use for ordinary protectionism dressed up as fairness, because proving 'unfairly low' pricing is slippery and political.
