Countervailing duties (CVDs), also known as anti-subsidy duties, are trade import duties imposed under World Trade Organization (WTO) rules. They are applied following an investigation that determines a foreign country's subsidies on exports have harmed domestic producers in the importing country. These duties aim to counterbalance the adverse impacts of such subsidies.
Petitions for remedies may be filed by domestic manufacturers or unions within the domestic industry, but the law requires that the petitioners represent at least 25% of the domestic production of the goods for which competition is causing material injury.
