📌 Event Summary: The Korea Trade Commission (KTC) finalized five-year anti-dumping duties on hot-rolled steel from China and Japan on February 23, 2026. Chinese imports face rates of 28.16%–33.10%. Japanese imports face rates of 31.58%–33.43%. Firms with KTC-approved price undertakings receive duty exemptions.
Background: How This Investigation Started
In early 2025, South Korean steel producers filed a formal dumping complaint with the KTC. Specifically, domestic mills claimed that Chinese and Japanese exporters sold hot-rolled flat steel below fair cost. As a result, the Korea Trade Commission hot-rolled steel investigation began shortly after.
After completing its review, the KTC issued an affirmative final determination. Indeed, the Commission confirmed that both Chinese and Japanese imports caused material injury to Korean producers. Therefore, the KTC requested that the Ministry of Economy and Finance impose the five-year duties.
Consequently, this South Korea anti-dumping duty hot-rolled steel order carries full legal force for five years. Furthermore, the KTC approved hot-rolled steel price undertaking Korea agreements from several firms. For buyers relying on Asian flat steel supply chains, this ruling demands immediate action.

Impact on Chinese and Japanese Exporters
This carbon steel anti-dumping Korea 2026 ruling creates immediate structural challenges for exporters. Moreover, the five-year duration means these challenges will persist well beyond 2026. Below is a breakdown of who the South Korea anti-dumping duty hot-rolled steel order affects most.
- Chinese steel exporters: They face final AD rates of 28.16%–33.10% on all covered flat steel products. As a result, Chinese mills lose a significant price advantage in the Korean market overnight.
- Japanese steel exporters: Their rates range from 31.58% to 33.43%, making Japan the higher-duty origin. Therefore, Japanese mills face even steeper challenges than their Chinese counterparts.
- Firms with KTC-approved price undertakings: Indeed, these companies continue selling into Korea without paying the full AD duty. Furthermore, they gain a clear competitive edge over rivals that did not enter undertakings.
- Korean importers and procurement teams: Consequently, raw material costs for imported flat steel will rise considerably. Additionally, procurement teams must review all existing supplier contracts right away.
- Automotive, construction, and appliance sectors: However, not all cost increases will arrive at once — they will push through the supply chain over months. Therefore, input cost budgets for H2 2026 need revision now.
In particular, the hot-rolled coil tariff China Korea impact falls hardest on mills without undertakings. Specifically, those exporters face the full published rates with no path to exemption.
Alternative Sourcing Strategies for Buyers
Fortunately, buyers have several strong supply alternatives to consider. For example, LYH Steel sources duty-safe hot-rolled flat steel from multiple compliant origins.
- First — Chinese mills with price undertakings: Some Chinese producers already hold KTC-approved pricing agreements. As a result, sourcing from these specific mills avoids the full AD duty entirely.
- Second — Indian steel mills: India has expanded flat-rolled capacity significantly in recent years. Moreover, Indian-origin hot-rolled steel does not fall under this Korean order.
- Third — Southeast Asian producers (Vietnam, Indonesia): Several mills in this region now supply competitive hot-rolled flat steel. Furthermore, these origins currently face no AD duties in the Korean market.
- Fourth — Taiwanese steel mills: Taiwan produces high-quality flat-rolled carbon steel products. In fact, Taiwanese-origin supply does not fall within this particular order at all.
- Fifth — Cold-rolled steel as a substitute: For some applications, cold-rolled steel (HS 7209) offers a viable product alternative. Additionally, cold-rolled is not covered by this order, so buyers face no AD duty on it.

Global Context: A Wider Trade Pattern
South Korea's ruling is part of a clear global trend in steel trade protection. Indeed, the South Korea anti-dumping duty hot-rolled steel decision follows similar actions by Mexico, South Africa, and Australia in the same month. For example, Mexico imposed provisional duties on hot-rolled steel from China and Vietnam in March 2026. In the same week, South Africa raised AD duties on structural steel from China and Thailand. Moreover, the United States issued a preliminary ruling on South Korean heavy-walled steel pipes. Therefore, buyers can no longer rely on a single low-cost import source for their needs. Instead, they need a diversified, duty-verified supply chain as a long-term strategy.
