[SMM Tungsten Express] Japan's response to China's tungsten export controls demonstrates that supply chain restructuring can effectively hedge geopolitical risks. After China imposed tungsten export controls in February 2025, Japan quickly pivoted to tungsten scrap from the US, Singapore and Europe, with US scrap exports to Japan surging 24-fold in Q1 2026. Major producers have initiated expansion plans: Mitsubishi Materials invested ~$64 million to expand recycling capacity in Japan and Europe, while Sumitomo Electric invested $100 million in a new plant expected to boost tungsten supply capacity by ~50% by 2028. The Japanese government is advancing public-private supply chain reform through its Economic Security Promotion Act and JOGMEC. This case underscores that critical minerals dependence is not merely a commercial issue but a strategic risk, accelerating efforts to build resilient supply chains.
