The Commission made a negative determination, finding that certain brake drums and rotors from China are not 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. All Commissioners voted in the negative.

As a result of the negative determination, the investigation will end.

The Commission will send its report to the President and the U.S. Trade Representative by August 25, 2003.

Section 421 was added to the Trade Act of 1974 by the U.S.-China Relations Act of 2000 and implements a transitional bilateral safeguard provision in the U.S.-China agreement relating to China's accession to the World Trade Organization. Domestic producers can obtain relief under this provision if the Commission finds that Chinese products are 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 statute states that market disruption "exists whenever imports of an article like or directly competitive with an article produced by a domestic industry are increasing rapidly, either absolutely or relatively, so as to be a significant cause of material injury, or threat of material injury, to the domestic industry." "Significant cause" is defined by the statute as "a cause which contributes significantly to the material injury of the domestic industry, but need not be equal to or greater than any other cause." Similar to global safeguard investigations, if the Commission makes an affirmative determination, it also proposes a remedy to the President. The President makes the final decision concerning whether to provide relief to the U.S. industry and if so, the type and duration of relief.
