Countervailing Duty

An extra charge that a country places on imported goods to counter the
subsidies or bounties granted to the exporters of the goods by their home
governments. The duty is allowed by the Code on Subsidies and
Countervailing Duties negotiated at the Tokyo Round, if the importing
country can prove that the subsidy would cause injury to domestic industry.
U.S. countervailing duties can only be imposed after

the International Trade Commission has determined that the imports are
causing or threatening to cause material injury to a U.S. industry.
