Japan imposes anti-dumping duties on nickel-based stainless steel from China and Taiwan, effective October 31, 2026, to protect domestic producers.
Japan has officially announced anti-dumping duties on nickel-based stainless steel cold-rolled strip and plate from mainland China and the Taiwan region.
Effective October 31, 2026, these duties range from 27.7% to 42.1% for Chinese products and 3.6% to 20.1% for Taiwanese products. This decision follows Japan's multi-year investigation, which began in July 2025, and reflects unchanged rates from the provisional duties imposed in July 2026. The duties will remain in place until October 2031.
Among Chinese producers, Shanxi Taigang and unsampled manufacturers face a 27.7% duty, while POSCO (Zhangjiagang) Stainless Steel Co., Ltd. and related suppliers face the highest rate of 42.1%. For Taiwanese producers, YUSCO and unsampled manufacturers are subject to 3.6%, while Walsin and related suppliers face 20.1%.
The targeted products are nickel-based stainless steel materials, used in industries including automotive, home appliances, precision equipment, and railway vehicles. These materials are high-value inputs due to their corrosion resistance and smoothness achieved through cold-rolling processes, making them integral to Japan's manufacturing sector.
Japan's investigation revealed an increase in imports from China and Taiwan, which negatively impacted domestic producers. Between 2022 and 2024, the market share of imported products rose by 32%, while comparable domestic sales volume and profit indices fell significantly. For Japanese producers, this drop in profitability—against rising imports—played a critical role in the decision to impose duties.
In 2025, Japan produced 80.67 million tonnes of crude steel, a 4% year-on-year drop, compared to China's 960.8 million tonnes. While Japan's steel industry operates on a smaller scale, its integrated production system remains vital for downstream manufacturers. However, growing import competition has prompted domestic producers to advocate for stronger trade protections.
These duties do not mean imports will cease. Japanese companies relying on foreign steel for specific specifications or capacity gaps will continue sourcing internationally. For Chinese exporters, this new tariff structure increases the urgency to diversify markets and optimize logistics. Exporters should focus on compliance documentation and explore alternative markets like Southeast Asia. Freight forwarders must adjust to shifting trade flows and evaluate new routing strategies to maintain efficiency.
Ultimately, while duties create challenges, Chinese steel suppliers retain competitive advantages in certain segments, emphasizing the need for flexible and strategic responses.
