Australia Anti-Dumping Probe Hits HSG, NKG with Preliminary Margin Up to 56%

Overview

Australia’s Anti-Dumping Commission has opened an anti-dumping investigation into galvanized steel imports from Vietnam and South Korea, specifically targeting Hoa Sen Group (HSG) and Nam Kim Steel (NKG). The preliminary dumping margin for Vietnamese exporters is estimated at up to 56.21%, based on a complaint by Australian steelmaker Blue Scope Steel. The investigation period runs from January 1 to December 31, 2025, with a final report due by October 2, 2026.

• The Anti-Dumping Commission of Australia initiated the investigation on April 30, 2026, following a complaint by Blue Scope Steel.
• The investigation covers galvanized steel products under HS codes 7210.49.00, 7212.30.00, 7225.92.00, and 7226.99.00.
• The preliminary dumping margin for Vietnamese exporters is estimated at up to 56.21%.
• The investigation period is from January 1, 2025, to December 31, 2025.
• The final report is expected to be submitted to the Minister for Industry and Innovation and the Minister for Science by October 2, 2026.

What Happened

On April 30, 2026, the Anti-Dumping Commission of Australia announced the initiation of an anti-dumping investigation into galvanized steel imports from Vietnam and South Korea. The probe was triggered by a complaint from Blue Scope Steel, which alleges that Vietnamese and South Korean exporters have been selling galvanized steel in Australia at prices below normal value, causing material injury to the domestic steel industry.

The investigation specifically names Hoa Sen Group (HSG) and Nam Kim Steel (NKG) as Vietnamese exporters under review. The preliminary dumping margin for Vietnamese firms is estimated at up to 56.21%. The Vietnam Trade Remedies Authority has urged the involved companies to cooperate fully with the Australian authorities and to prepare responses in the correct format and within deadlines. Non-cooperation could result in the use of adverse facts available and the imposition of the highest possible anti-dumping duties.

Market Context

HSG closed at VND 15,000 on April 10, 2026, down 0.97% with a volume of 2.28 million shares on HOSE. NKG closed at VND 14,000, down 1.04% with a volume of 3.26 million shares on HOSE. The steel sector has been under pressure from global trade tensions and oversupply concerns. This anti-dumping investigation adds to the regulatory headwinds facing Vietnamese steel exporters, who have already faced similar probes in other markets.

Strategic Significance

For HSG and NKG, the Australian investigation represents a material risk to their export revenue from galvanized steel, a key product line. Australia is a significant market for Vietnamese coated steel, and a final determination of dumping with high duties could force a shift in sales to other markets or a reduction in production. The outcome will also set a precedent for other potential trade actions against Vietnamese steel. Companies that actively cooperate and build a strong defense may mitigate the impact, while those that fail to engage could face the maximum penalty.

What to Watch

• The final dumping margin determination and any provisional duties that may be imposed before the final report.
• The response and cooperation level of HSG and NKG with the Australian authorities.
• Any shift in export volumes to other markets such as the US, Europe, or ASEAN as a result of the investigation.
• Potential follow-on anti-dumping investigations from other countries against Vietnamese steel products.
• The impact on HSG and NKG’s Q2 2026 earnings reports and forward guidance.
