Final findings in anti-dumping investigations determine dumping and injury and recommend duties to address material injury. The designated authority must, within one year of initiation, determine dumping and submit a final finding specifying export price, normal value, margin of dumping, injury causation, any causal link, and whether a retrospective levy is warranted, recommending duties to remove injury. An affirmative finding must explain facts, methodology and reasons, identify suppliers or supplying countries, provide a customs-usable product description, establish margins and methodology, address injury considerations, determine individual margins for known exporters or producers, permit sampling where impracticable, and issue a public notice.
