Korea's hot-rolled steel market is widely seen as having entered a structural shift since the 2025 anti-dumping actions.
The government opened an investigation in March 2025, issued a preliminary ruling in July, and from September 23 imposed provisional anti-dumping duties of 28.16-33.1% on Chinese products and 31.58-33.57% on Japanese products, a measure extended through June 22, 2026, according to industry reporting.
Plate products saw similar treatment, with anti-dumping duties of 27.91-38.02% on Chinese plate and 28.16-33.10% on Chinese hot-rolled coil and 31.58-33.43% on Japanese hot-rolled coil reshaping market order.
On pricing, Hana Securities data cited in industry reports showed that as of May 11, 2026, domestic hot-rolled coil traded around KRW 960,000 per ton, rebar KRW 865,000, and plate KRW 990,000, up 8.8-21.8% from the start of the year by product.
Sector-wide improvement has also been evident, with POSCO's operating profit up 24%, Hyundai Steel returning to profit, and Dongkuk Steel posting an operating-profit jump exceeding 400%.
Even so, the Korea Institute for Industrial Economics and Trade projected continued weakness for the steel industry, and the EU's Carbon Border Adjustment Mechanism, in force since January, is expected to add roughly KRW 2.644 trillion in costs over nine years, with the effects of the United States' 50% tariff also remaining a variable.
Company-monitoring sources note that hot-rolled coil prices affecting Samhyun Steel's products have continued to rise amid supply adjustments, maintenance shutdowns, and anti-dumping duties, with plate prices also trending higher on supply-price increases.
However, how the minimum import price under negotiation for Chinese exports is ultimately set matters, as some industry observers note that a phased return of Chinese volume could slow the price uptrend and lead to a gradual pullback, meaning price strength is not guaranteed to persist automatically.
Samhyun Steel, as an authorized distributor for both POSCO and Hyundai Steel, is positioned to directly benefit from widened price spreads tied to the duties, but as a distribution business it remains highly exposed to raw-material procurement price swings and the pace of downstream demand recovery.
