Almost all countries have antidumping laws which regulate their imports. The United States and other countries enforce these laws within the terms of the World Trade Organization ("WTO"). There is a difference between U.S. enforcement and the enforcement approach of other countries, however. The United Statesbut not other countries of which I am aware--now uses 'zeroing' in its determination of whether imports are dumped. The use of 'zeroing' will almost always increase the level of any antidumping duty, and will sometimes create a duty where none would have been imposed, had the methodology not been used.
