The Department of Commerce yesterday initiated an anti-dumping investigation of imports of phosphor copper from South Korea.
The investigation covers phosphor copper, which is a master alloy of copper containing 5% or more of phosphorus, by weight. Phosphor copper is used as a deoxidizer, as an alloying additive that increases strength, hardness, and elasticity, and in brazing alloys to lower the melting temperature and improve wetting characteristics. It’s also used in the manufacture of copper tubing and brazing rods and is also used by brass mills and foundries.
The petitioner for the investigation is Metallurgical Products Company of Pennsylvania.
The merchandise covered by the investigation is master alloys of copper containing between 5 and 17% phosphorus by nominal weight, regardless of form including, but not limited to, shot, pellet, waffle, ingot, or nugget, regardless of size or weight.
In 2015, imports of phosphor copper from South Korea were valued at an estimated $4.3 million. The U.S. International Trade Commission is scheduled to make its preliminary injury determination on or before April 25.
