TAIPEI, TAIWAN — Following an official application submitted by Taiwan’s primary stainless steel producers—Yieh United Steel Corporation (Yusco) and Tang Eng Iron Works Co., Ltd.—Taiwan’s Ministry of Finance (MOF) has officially initiated an anti-dumping investigation targeting cold-rolled stainless steel flat products imported from Vietnam.
The investigation, announced by the Customs Administration, Ministry of Finance, aims to address unfair market competition and protect the domestic manufacturing supply chain against injurious dumping practices.
Investigation Scope and Product Specifications
The anti-dumping petition applies to flat-rolled stainless steel products originated in and exported from Vietnam, regardless of whether they are shipped in coils or cut lengths:
Product Dimensions: Cold-rolled flat products with a thickness of 0.05 mm (inclusive) up to 6.10 mm (inclusive), whether or not surface-treated or further processed.
Exclusions: Flat products coated, plated, or clad with other metals are explicitly excluded from this proceeding.
Target Applications: These cold-rolled flat coils and sheets serve as primary raw materials for kitchenware, food processing equipment, home appliances, architectural hardware, aerospace components, petrochemical processing, industrial machinery, and automotive manufacturing.
Procedural Timeline and Retroactive Duty Requests
According to the official notice, the investigation follows a strict multi-agency timeline under domestic trade relief regulations:
Injury Determination (Ministry of Economic Affairs): The International Trade Administration (ITA) of the Ministry of Economic Affairs (MOEA) will conduct an initial injury investigation to determine whether Vietnamese imports cause material injury to domestic producers.
Preliminary Dumping Determination (Ministry of Finance): If the MOEA confirms industry injury, the MOF will proceed to issue a preliminary determination regarding dumping margins and evaluate provisional anti-dumping duties.
Application for Retroactive Anti-Dumping Duties: To prevent importers from surging shipments prior to the decision, Yusco and Tang Eng have formally requested retroactive anti-dumping duties covering eligible shipments imported within 90 days prior to the application of provisional measures.

Strategic Guidance for Importers and Overseas Exporters
The Customs Administration has outlined clear compliance recommendations for international trade participants:
Individual Duty Rate Applications: Vietnamese manufacturers and exporters that fully cooperate with the customs investigation are eligible for individual dumping duty rates based on verified operational data.
Importers’ Documentation Standards: Local Taiwanese importers purchasing from compliant suppliers must present verified trade and manufacturing documentation demonstrating direct export from participating manufacturers to qualify for specific individual duty rates.
Supply Chain Origin Audits: International buyers and distributors sourcing stainless steel processed in Southeast Asia should ensure complete heat traceability and origin documentation to manage potential tariff exposure during the review period.
