Australia Anti-Dumping Probe Targets HSG, NKG Galvanized Steel at 56.21% Margin

Overview

Australia has initiated an anti-dumping investigation into galvanized steel imports from Hoa Sen Group (HSG) and Nam Kim Steel (NKG), two of Vietnam’s largest steel exporters. The probe, triggered by a complaint from Australian steelmaker BlueScope, alleges a dumping margin of 56.21%. The case is in its early stages, with a final report expected by October 2, 2026.

Key Facts

• Australia’s Anti-Dumping Commission initiated the investigation on April 30, 2026, following a complaint by BlueScope Steel.
• The alleged dumping margin for HSG and NKG is 56.21%, as stated in BlueScope’s application.
• The investigation covers galvanized steel imports from Vietnam and South Korea during 2025.
• HSG previously faced a similar anti-dumping case in Australia in 2015, which concluded with a 0% dumping margin.
• The final report is due to be submitted to relevant Australian ministries by October 2, 2026.
• HSG and NKG are advised by Vietnam’s Trade Remedies Authority to fully cooperate with the investigation to avoid the highest possible anti-dumping duties.
• On April 10, 2026, HSG shares closed at VND 15,000 (-0.97%), and NKG closed at VND 14,000 (-1.04%).

What Happened

On April 30, 2026, the Anti-Dumping Commission of Australia’s Department of Industry, Science and Resources announced the initiation of an anti-dumping investigation into galvanized steel imports from Hoa Sen Group (HSG) and Nam Kim Steel (NKG), along with two South Korean companies. The probe was launched at the request of Australian steel producer BlueScope, which alleges that Vietnamese and Korean steel is being sold in Australia below normal value, causing injury to the domestic industry.

In a press release on May 11, 2026, Hoa Sen Group stated that the case is still at the initiation stage and that the 56.21% margin is an initial allegation by BlueScope, not a preliminary or final conclusion by the Australian authorities. The company noted that complainants often use high assumed margins to support the initiation of investigations. HSG also recalled its 2015 experience, where an initial 16.26% allegation was reduced to 0% after investigation.

Market Context

Both HSG (listed on HOSE) and NKG (listed on HOSE) have seen recent price weakness, with HSG closing at VND 15,000 (-0.97%) and NKG at VND 14,000 (-1.04%) on April 10, 2026, on moderate volume. The steel sector in Vietnam has been under pressure from global trade tensions and oversupply concerns. This anti-dumping probe adds to the regulatory headwinds facing Vietnamese steel exporters, particularly in developed markets like Australia.

Strategic Significance

For long-term investors, the outcome of this investigation could materially affect HSG and NKG’s export revenues and profitability. Australia is a key market for Vietnamese galvanized steel, and a final determination of dumping could lead to significant anti-dumping duties, reducing competitiveness. However, HSG’s successful defense in the 2015 case provides a precedent that the initial allegations may not reflect the final outcome. The companies’ cooperation with the investigation and their ability to present accurate cost data will be critical. Diversification of export markets and product lines remains a strategic imperative.

What to Watch

• Interim findings or preliminary determinations from the Australian Anti-Dumping Commission, expected before the October 2 deadline.
• Any announcements from HSG or NKG regarding their legal strategy and cooperation with the investigation.
• Updates on export volumes and pricing of galvanized steel to Australia in the coming quarters.
• Reactions from other Vietnamese steel exporters, as the case may set a precedent for future trade actions.
• Q2 2026 earnings reports from HSG and NKG, which may include provisions for potential liabilities.
