These are investigations that the Commission conducts under section 421 of the Trade Act of 1974 (19 U.S.C. 2451) concerning whether a product from China is being imported into the United States in such increased quantities or under such conditions as to cause or threaten to cause market disruption to the domestic producers of like or directly competitive products. The Commission conducts investigations on the basis of a petition, at the request of the President or the U.S. Trade Representative, upon resolution of the House Committee on Ways and Means or Senate Committee on Finance, or on the Commission's own motion. If the Commission makes an affirmative determination, it proposes a remedy to the President and the U.S. Trade Representative. The President makes the final remedy decision.
