Vietnam Reviews AD Duties on Coated Steel from South Korea and China
Vietnam is reviewing anti-dumping duties on coated steel from South Korea and China, while interested parties may submit reassessment applications by July 14, 2026.
Vietnam reviews AD duties on coated steel from South Korea and China as the Ministry of Industry and Trade, or MOIT, reassesses existing trade remedies. Therefore, exporters, Vietnamese importers and downstream steel users should review duty exposure before signing new contracts.
The Trade Remedies Authority is accepting reassessment applications from interested parties until July 14. In addition, the review will decide whether Vietnam should maintain, adjust or terminate the current anti-dumping duties.
Background of Vietnam’s coated steel AD case
The investigation began after five Vietnamese manufacturers filed complaints. These companies included Hoa Sen Group, Nam Kim Steel, Ton Phuong Nam, Ton Dong A and China Steel And Nippon Steel Vietnam. They argued that dumped coated steel imports damaged the domestic industry.
After the investigation, Vietnam imposed final anti-dumping duties last August. As a result, South Korean coated steel products faced rates up to 15.67%, while Chinese coated steel products faced rates up to 37.13%.

| Application deadline | Therefore, submissions are due by July 14, 2026 |
| South Korea duty range | Up to 15.67% |
| China duty range | By contrast, Chinese products face rates up to 37.13% |
| Possible outcome | Overall, duties may be maintained, changed or removed |
Product scope and duty exposure
The case covers imported coated steel products, commonly including galvanized or zinc-coated steel used in construction, roofing, panels, appliances and light industrial fabrication. However, buyers should confirm the exact tariff classification and product description before shipment.
Vietnamese authorities previously found a direct link between low-priced imports and material injury to local mills. Therefore, importers should not treat the review as an automatic duty reduction. Instead, they should prepare for several possible outcomes.
Impact on exporters and coated steel buyers
For Chinese and South Korean exporters, the review creates both risk and opportunity. If evidence supports a lower margin, duty rates may change. However, if injury concerns remain strong, Vietnam may keep the current measures.
For Vietnamese buyers, landed cost remains the main issue. In addition, contracts signed before the review outcome should define who bears duty changes. Otherwise, a competitive offer may become less attractive at customs clearance.
Global buyers should also watch this case. As a result, coated steel volumes from China or South Korea may shift to other Southeast Asian markets if Vietnam keeps strict duties.
Procurement and quality control advice
First, buyers should confirm origin, coating type, coating weight, thickness, width, surface treatment, coil weight and packing method. In addition, they should request a Mill Test Certificate and origin documents before shipment.
Next, procurement teams should compare coated steel with alternative materials based on use environment. For example, stainless steel may offer better lifecycle value in coastal, humid or chemical-exposure projects.
Finally, supplier review should cover export experience, document accuracy, claims handling and delivery reliability. Therefore, buyers can reduce both trade-policy risk and quality risk.
Market outlook for coated steel trade
Overall, Vietnam is likely to keep a cautious position because local mills still compete with low-priced imports. However, the review process may give exporters a chance to submit updated pricing, cost and injury evidence.
Meanwhile, Southeast Asian steel trade remains sensitive to anti-dumping actions. Therefore, buyers should keep quotation validity short, diversify approved suppliers and monitor MOIT announcements before confirming large orders.
