Levy of anti-dumping duty: government may impose duty on dumped imports after final findings and investigation. Imposition of anti-dumping duty follows final findings and is notified by the Central Government; duty shall not exceed the margin of dumping. For selected exporter examinations, duties on others are limited to weighted average margins or differences based on prospective normal value; zero and negligible margins are disregarded and individual duties may apply if exporters supply required information. Where the domestic industry proviso applies, duty follows failure to cease dumping or to give an undertaking, and negative final findings require withdrawal of any provisional duty.
