Anti-dumping investigation into hot rolled steel imports alleges dumping and invites submissions; prima facie injury asserted. The Authority initiates an anti-dumping investigation into hot rolled coils/sheets/plates/strips from Russia, Ukraine and Kazakhstan after a petition by domestic producers representing about 78% of production. Petitioners claim normal values for Russia based on local prices and for Ukraine and Kazakhstan on cost-of-production estimates, and assert export prices from customs data, yielding prima facie dumping margins. They allege material injury through increased imports, profit decline, rising inventories and price depression. The investigation covers a specified twelve-month period; interested parties must submit information within forty days and non-cooperation may lead to facts-available findings.
