Yieh United Steel Corporation (Yusco) renewed an anti-dumping (AD) investigation petition in early July targeting Vietnamese 304 cold-rolled stainless steel exports, driven by surging import volumes.

Customs data showed imports reached nearly 6,200 tons in June and 6,000 tons in July, a 168% surge compared to the previous year, with total imports hitting 23,200 tons in the first seven months of this year.

Although formal case registration remains pending, the Customs Administration scheduled a preliminary hearing for September 14 due to heavy administrative workloads. Importers expressed concern over potential retroactive AD duties affecting existing unfulfilled contracts.

Yusco and Tang Eng previously filed a similar request in October 2025 before temporarily withdrawing it, but renewed market pressures and sluggish local demand prompted the latest regulatory action to safeguard fair competition.
