Phosphor Copper from Korea Injures U.S. Industry, Says USITC

The United States International Trade Commission (USITC) today determined that a U.S. industry is materially injured by reason of imports of phosphor copper from Korea that the U.S. Department of Commerce (Commerce) has determined are sold in the United States at less than fair value. 

Chairman Rhonda K. Schmidtlein, Vice Chairman David S. Johanson, and Commissioners Irving A. Williamson, Meredith M. Broadbent, and F. Scott Kieff voted in the affirmative.

As a result of the USITC’s affirmative determination, Commerce will issue an antidumping duty order on imports of this product from Korea.

The Commission’s public report Phosphor Copper from Korea (Investigation No. 731-TA-1314 (Final), USITC Publication 4681, April 2017) will contain the views of the Commission and information developed during the investigation.

The report will be available by May 3, 2017; when available, it may be accessed on the USITC website at:

Product Description:  Phosphor copper is a master alloy composed primarily of copper (Cu) and phosphorus (P), but may contain small amounts of iron, lead, tin, and other elements. As it is most commonly sold, phosphor copper contains approximately 15 percent phosphorus by weight. Phosphor copper is an additive in the manufacture of other alloys and has three primary uses: 1) as a deoxidizer; 2) as an alloying additive that increases strength, hardness, and elasticity; and 3) in brazing alloys.
