The U.S. Commerce Department on Wednesday said imports of steel concrete reinforcing bar from Japan, Taiwan and Turkey were being dumped in the U.S. market at below fair value.

As part of its decision, it assigned preliminary dumping margins of 209.46 percent for Japanese exporters, including Jonan Steel Corp and Kyoei Steel Ltd (5440.T) . It assigned margins ranging up to 29.47 percent for Taiwanese exporters and up to 7.07 percent for Turkish producers.

The preliminary determination follows a petition for an investigation by a U.S. rebar trade coalition and its members: Commercial Metals Co (CMC.N) , Gerdau SA''s (GGBR4.SA) Gerdau Ameristeel U.S. Inc, Nucor Corp (NUE.N) and Steel Dynamics Inc (STLD.O) .

Steel concrete reinforcing bar, or rebar, is used in construction to help strengthen structures and lessen the impact from stressors such as tension and temperature.

Imports of rebar in 2015 were valued at an estimated $108.69 million from Japan, $17.57 million from Taiwan and $674.40 million from Turkey, according to the department.  压铸展-铸造展-2017第十八届广州国际压铸、铸造及工业炉展览会-中国最受关注的压铸铸造展会-巨浪展览-The 18th Guangzhou Die-casting, Foundry & Industry Furnace Exhibition
