Vietnam Anti-Dumping Probe on Chinese Prestressed Steel: HPG Impact

Overview

Vietnam’s Ministry of Industry and Trade (MOIT) has initiated an anti-dumping investigation into certain prestressed steel bars imported from China, following a petition from domestic producers including Hoa Phat (HPG). The alleged dumping margin is 23.06%, but this is not a final determination. The probe could lead to protective tariffs, benefiting HPG and other domestic steelmakers.

Key Facts

• MOIT initiated an anti-dumping investigation on certain prestressed steel bars from China on [date not specified].
• The petition was filed by Hoa Phat Prestressed Steel Co., Ltd. (a subsidiary of HPG) and Viet-Nhat Prestressed Steel JSC.
• The alleged dumping margin is 23.06%, as claimed by the petitioners.
• The investigation period for dumping is from July 1, 2025 to June 30, 2026; injury period is from July 1, 2022 to June 30, 2026.
• Products under investigation include certain silicon-manganese alloy steel bars, rods, or coils with diameters of 7.1-12.6 mm, classified under HS codes 7227.20.00, 7228.20.11, 7228.20.19, and 7229.20.00.
• Vietnam already applies anti-dumping duties on Chinese HRC steel at 23.1-27.83% for five years, and a temporary anti-circumvention measure on certain HRC widths.

What Happened

Vietnam’s Ministry of Industry and Trade has decided to investigate allegations that Chinese prestressed steel bars are being dumped into the Vietnamese market, causing material injury to the domestic industry. The probe was initiated after receiving a petition from two domestic producers: Hoa Phat Prestressed Steel Co., Ltd. and Viet-Nhat Prestressed Steel JSC. The petitioners claim that the dumping margin is 23.06%, but MOIT emphasizes that this is only an allegation and not a final conclusion.

The investigation covers specific steel products: silicon-manganese alloy steel bars, rods, or coils, not plated or coated, with a circular cross-section, smooth or with longitudinal ribs, and diameters between 7.1 mm and 12.6 mm. The dumping investigation period runs from July 1, 2025 to June 30, 2026, while the injury assessment period spans from July 1, 2022 to June 30, 2026.

Market Context

HPG, listed on HOSE, closed at VND 21,650 on July 29, 2026. The steel sector has been under pressure from cheap Chinese imports, with Vietnam already imposing anti-dumping duties on Chinese HRC steel. This new investigation targets a niche product segment, potentially providing additional protection for HPG’s prestressed steel business. The broader Vietnamese steel market has seen increased trade defense measures, reflecting ongoing competition with Chinese producers.

Strategic Significance

For HPG, this investigation represents a strategic move to protect its downstream steel product lines. HPG has been expanding its value-added steel products, including prestressed steel, which commands higher margins. If anti-dumping duties are imposed, it could reduce competition from Chinese imports and support HPG’s pricing power and market share. The outcome may also influence HPG’s investment in capacity expansion for specialty steels.

What to Watch

• MOIT’s preliminary determination on dumping and injury, expected within 6-12 months.
• Any provisional anti-dumping duties imposed during the investigation.
• HPG’s Q3 2026 earnings report for impact on its prestressed steel segment.
• Changes in import volumes of the subject products from China.
• Potential retaliation or trade tensions between Vietnam and China.
