Encore Wire (WIRE) said on Friday it supports the US government’s anti-dumping and countervailing duty (CVD) investigations of aluminum wire and cable from China, accusing Chinese aluminum building wire producers of illegally dumping their product in the country in its preliminary ruling.

“These illegal trade practices have undermined our investments in aluminum wire production, which is an important complement to our market-leading copper building wire business,” said CEO Daniel Jones. The Commerce Department is scheduled to issue its final anti-dumping and CVD determinations by the end of the year.
