Japan Slaps 3.6%-42.1% Provisional Anti-Dumping Duties on Chinese and Taiwanese Stainless SteelA · FULL TRANSLATION
- Japan's cabinet approved provisional anti-dumping duties on nickel-based cold-rolled stainless steel from China and Taiwan
- Duties of 3.6% to 42.1% apply from July 9 through November 8
- A joint MOF-METI investigation has run since July 2025
- Authorities found presumed dumping and material injury to domestic industry
- A decision on definitive duties comes next; Taiwan's steel exports to Japan face new costs
From July 9, nickel-based cold-rolled stainless steel strip and sheet from Taiwan and China entering Japan will carry provisional anti-dumping duties of 3.6% to 42.1%, running through November 8. The cabinet approved the ordinance on July 3 after a joint Finance-METI investigation launched in July 2025 found presumed dumping and material injury to Japanese producers.
For Taiwan's steelmakers this is a rare direct hit: at the upper end of the duty range, affected exporters are effectively priced out of the Japanese market. The next battleground is whether provisional duties convert into definitive ones, which can last up to five years. The broader signal is that Japan is turning more assertive on trade defense in steel amid global overcapacity and the spillover of Chinese exports—and suppliers caught in between, like Taiwan, can get swept in.
Watch customs practice after July 9, the definitive-duty decision, and whether Taipei pursues WTO or bilateral consultations. Japan's door is not closed, but the ticket just got pricier—and repricing along the supply chain is where risk and opportunity get redistributed.
[Ministry of Finance announcement, July 3, 2026 — abridged translation] The cabinet today approved an ordinance imposing provisional anti-dumping duties on nickel-based cold-rolled stainless steel strip and sheet originating in or exported from the People's Republic of China (excluding Hong Kong and Macau) and the separate customs territory of Taiwan, Penghu, Kinmen and Matsu.
The measure follows an investigation, opened on July 22, 2025 upon petition from domestic producers and conducted jointly by the Ministry of Finance and METI, which found on June 19 that dumped imports and material injury to Japanese industry could be presumed. On June 23 the Council on Customs, Tariff, Foreign Exchange and Other Transactions recommended provisional duties as appropriate, at rates of 3.6% to 42.1%.
The ordinance will be promulgated on July 8; provisional duties apply from July 9 through November 8, 2026. The covered products are alloy steels containing at least 10.5% chromium and more than 0.6% nickel by weight, valued for corrosion resistance and surface finish and used across a wide range of applications.
