Safeguard duty recommended after finding increased imports causing serious injury to domestic hot-rolled steel producers. Preliminary findings of a safeguard investigation into hot rolled flat steel coils (PUC) determine that sharply increased imports, driven by excess global capacity and currency/market shifts in exporting countries, have caused and threaten to cause serious injury to domestic producers. Objective indicators-rising import volumes and market share, falling domestic market share and prices, rising inventories and recent losses-establish a causal link. Critical circumstances are found, and a provisional ad valorem safeguard duty of twenty percent for a provisional period is recommended pending further verification and final determination.
