South Korea Finalizes Anti-Dumping Measures on Chinese Stainless Plates
South Korea has officially imposed a 21.62% anti-dumping duty on stainless steel plates imported from China.
The decision follows a detailed year-long investigation into unfair pricing practices that allegedly harmed the domestic steel industry.
The five-year definitive duty, effective from September 2025, was formalized under Ministry of Economy and Finance (MOEF) Decree No. 1140.
Authorities said the measure aims to restore fair market competition and safeguard local producers from sustained dumping pressure.
Background and Investigation Timeline
The anti-dumping investigation began in September 2024 after a petition filed by DK Corp, South Korea’s sole producer of stainless steel plates.
A provisional duty was first introduced in March 2025 for four months, later extended by 40 days to prevent import surges during review.
Following the final determination in September 2025, the government concluded that Chinese exporters had sold stainless plates in Korea at prices below normal value, causing material injury to domestic manufacturers.
Product Scope and HS Codes
The duty applies to stainless steel plates meeting the following criteria:
Thickness: Minimum 4.75 millimeters
Width: At least 600 millimeters
HS Codes: 7219.21.1010, 7219.22.9000, and related categories
However, several products are explicitly excluded from this measure:
Hot-rolled coils and black plates
Plates below 8mm thickness and 2,000mm width
This precise definition ensures the duty targets only thick stainless plates, avoiding disruption to other downstream products.
Market and Trade Impact
Chinese exporters will now face higher import costs, forcing some to absorb the duty or redirect shipments to alternative markets in Southeast Asia or Europe.
For South Korean buyers, prices of stainless steel plates are expected to rise.
This could affect construction, shipbuilding, and manufacturing sectors, which rely on steady plate supply.
Trade data shows import surges earlier in 2025 — shipments from China doubled in January ahead of the final decision, suggesting that importers anticipated the new tariff.
Industry analysts predict short-term supply adjustments, though domestic producers like DK Corp may benefit from improved capacity utilization.
Global Trade Context
South Korea’s move aligns with a broader wave of trade protectionism across global steel markets.
Countries worldwide — including the EU, India, and the United States — have tightened anti-dumping actions on Chinese steel products.
Meanwhile, China itself maintains anti-dumping measures on stainless imports from the EU, UK, Korea, and Indonesia, creating a complex web of trade defenses and retaliatory barriers.
To prevent circumvention, South Korea is also enhancing customs monitoring, including stricter origin verification to block re-routed Chinese steel through third countries.
Conclusion
The new anti-dumping duty on Chinese stainless steel plates underscores South Korea’s effort to defend domestic manufacturers amid rising global trade tensions.
With enforcement expected to remain tight, both exporters and importers must reassess supply chains, pricing, and sourcing strategies to adapt to this evolving trade environment.
