U.S. agency finds harm from imported carbon and steel plate

(Adds background on duties, use, petitioners)

WASHINGTON, May 5 (Reuters) - U.S. trade officials on Friday said their anti-dumping and subsidy probe found carbon and alloy steel cut-to-length plate from eight foreign producers harms American manufacturers, locking in duties on the imports for five years.

The U.S. International Trade Commission's finding applies to cut-to-length plate from Austria, Belgium, France, Germany, Italy, Japan, South Korea and Taiwan, it said in a statement on its website.

In March, the U.S. Commerce Department said anti-dumping duties ranging from 3.62 percent to 148 percent would be imposed on products from the eight producers, while imports from South Korea would also face a countervailing duty of 4.31 percent.

Cut-to-length steel is used in a wide range of applications, including buildings and bridgework; agricultural, construction and mining equipment; machine parts and tooling; ships, rail cars, tankers and barges; and large-diameter pipe.

The findings followed an investigation prompted by a petition from Nucor Corp and U.S. subsidiaries of ArcelorMittal SA and SSAB AB. (Writing by Susan Heavey and Eric Walsh; Editing by James Dalgleish)
