Vietnam has established a firm foothold, consistently ranking among the leading suppliers of stainless steel flanges to the US.

The country is currently the third-largest exporter of this product to the US market.

In 2023, total US imports of the product reached $218 million, of which Vietnam accounted for $21.4 million, holding 9.8% of the market share. While India, South Korea and Italy remained the top suppliers, Vietnam’s position ahead of China underscored its strong manufacturing and export capacity.

In 2024, overall US imports declined to $185.7 million. Vietnam’s exports fell 42.3% to $12.3 million, reducing its market share to 6.6%. However, the downturn proved temporary. By 2025, the market rebounded, with total imports rising to $205.6 million. Vietnam’s exports also recovered to $18 million, lifting its share to 8.7%.

In the first months of 2026, despite a 37% year-on-year drop to $1.8 million in the January–February period, Vietnam maintained its position as the third-largest supplier to the US.

Despite its potential, the US market poses significant challenges. The Trade Remedies Authority of Vietnam has warned that stainless steel flanges are a high-risk product subject to trade defense investigations, including anti-circumvention probes.

One key risk stems from stringent US anti-dumping duties imposed on similar imports from China and India. This has prompted US authorities to tighten scrutiny of other exporting countries to prevent transshipment or minimal processing designed to bypass tariffs.

Against this backdrop, Vietnamese exporters are advised to strictly monitor the origin of raw materials. Heavy reliance on inputs from China and India could expose firms to allegations of tariff evasion. Ensuring compliance with rules of origin is therefore not only a legal requirement but also a critical safeguard. Companies are urged to adopt proactive trade defense strategies rather than reacting only after disputes arise.
