In 1921, a new antidumping act was enacted into domestic law., The Antidumping Act of 1921 was part of a coordinated effort by the U.S. government to protect infant U.S. industries, particularly the petrochemical industry which burgeoned during World War I, from the increasing competition of European industries seeking markets to utilize capacity which had been devoted to war efforts. The Act was directed against international price discrimination, and the substance of its principal operative provision remained unchanged through a series of amendments. Basically, the Antidumping Act provides that articles imported into the United States will be subject to a special duty when such articles are being, or are likely to be, sold at less than fair value' and an industry in the United States is being, or is likely to be, injured or is prevented from being established by reason of the importation into the United States of the articles.
