Taiwan’s Customs Administration, Ministry of Finance, announced the formal launch of an anti-dumping (AD) investigation targeting certain cold-rolled, flat-rolled stainless steel products imported from Vietnam, following a petition filed by Yieh United Steel Corporation (Yusco) and Tang Eng Iron Works.

The Ministry of Economic Affairs will evaluate potential industrial damage within 40 days of receiving the notification, while the Ministry of Finance will review dumping margins.

The investigative period covers July 1, 2025, to June 30, 2026. Officials noted that surging import volumes priced below domestic production costs caused severe market share losses and financial strain for local producers.

The products involved are specific cold-rolled stainless steel flat products in coils or sheets, with thicknesses ranging from 0.05 mm to 6.10 mm, nickel content between 5% and 20%, chromium content between 15% and 25%, manganese content up to 3%, and aluminum content up to 0.5%, excluding coated or plated products.

These affected products are under HS codes 72193110102, 72193110905, 72193190114, 72193190123, 72193190196, 72193190203, 72193190908, 72193210101, 72193210904, 72193290113, 72193290122, 72193290195, 72193290202, 72193290907, 72193310100, 72193310903, 72193390112, 72193390121, 72193390194, 72193390201, 72193390906, 72193410109, 72193410902, 72193490111, 72193490120, 72193490193, 72193490200, 72193490905, 72193510108, 72193510901, 72193590110, 72193590129, 72193590192, 72193590209, 72193590904, 72199000905, 72202010102, 72202010905, 72202090114, 72202090123, 72202090196, 72202090203, 72202090908, 72209010198, 72209010991, 72209090146, 72209090164, 72209090191, 72209090299, and 72209090994.
