Section 337

Section 337 of the Tariff Act of 1930 requires investigations of unfair
practices in import trade. Under this authority, the International Trade
Commission applies U.S. statutory and common law of unfair competition to
the importation of products into the United States and their sale. Section
337 prohibits unfair competition and unfair importing practices and sales
of products in the U.S., when these threaten to: (a) destroy or
substantially injure a domestic industry, (b) prevent the establishment of
such an industry, or (c) restrain or monopolize U.S. trade and commerce. Section
337 also prohibits infringement of U.S. patents, copyrights, registered
trademarks, or mask works.
