19 U.S.C. § 1673 — Antidumping duties imposed

If (1) the administering authority decides that a class or kind of foreign merchandise is being, or is likely to be, sold in the United States below fair value, and (2) the Commission decides that imports, or sales or likely sales for importation, materially injure a United States industry, threaten such injury, or materially delay establishing one, the merchandise must receive an antidumping duty in addition to other duties. The amount equals the excess of normal value over the export price or constructed export price. For this section and section 1673d(b)(1), “sale” of foreign merchandise also includes a lease arrangement equivalent to a sale. This section does not define “fair value,” “normal value,” or “constructed export price.”
