Why supply is constrained

Critical

China produced 99% of primary low-purity gallium in 2024 and 2025 (USGS); the US has recovered no primary gallium since 1987. China licensed exports from August 2023 and banned exports to the US in December 2024, a ban it suspended in November 2025 until 27 November 2026. Non-Chinese projects (Alcoa Wagerup, Rio Tinto Quebec, Metlen Greece, ElementUSA Louisiana) are mostly pre-production.
