Anti-dumping investigations are to end immediately in cases where the authorities determine that the margin of dumping is, "de minimis," or insignificantly small (defined as less than 2% of the export price of the product). Other conditions are also set. For example, the investigations also have to end if the volume of dumped imports is negligible (i.e., if the volume from one country is less than 3% of total imports of that product—although investigations can proceed if several countries, each supplying less than 3% of the imports, together account for 7% or more of total imports).
