# Minor metals chokepoints: gallium, germanium, antimony, tungsten, platinum and palladium > Six metals underpinning semiconductors, defence alloys and autocatalysts where China or Russia controls supply, making export restrictions a primary geopolitical weapon. **Meta:** type: reference · date: 2026-07-03 · heads: · 5 takes · 2 lenses · 2 regions ## What it is This beat tracks six metals, gallium, germanium, antimony, tungsten, platinum and palladium, that share a common strategic profile: each is essential to a high-technology or defence application and produced in concentrated geographic chokepoints. None is mined at large enough scale to buffer extended supply disruptions. A world-news reader tracks this beat because these metals sit at the intersection of the semiconductor supply chain, the defence industrial base and the autocatalyst market that governs the pace of the petrol-to-electric-vehicle transition. China holds dominant positions in four of the six metals; Russia holds a critical position in palladium. Export controls and sanctions are now active leverage tools on both sides. ## History China's export-control programme began in August 2023 with gallium and germanium, requiring licences for the first time from a country that produces roughly 98% of global primary gallium and around 60% of refined germanium. Beijing extended restrictions to antimony in September 2024, triggering a price surge that at peak represented a gain of more than 2,600% from 2023 lows. Tungsten controls followed in February 2025. China placed US-specific bans on gallium and germanium in April 2025, then expanded end-user vetting across all controlled metals in June 2026. For platinum and palladium, the inflection came with Russia's February 2022 invasion of Ukraine: Norilsk Nickel (Nornickel), operating from Murmansk in north-west Russia, supplies roughly 40-45% of global refined palladium and around 11% of refined platinum. The EU's successive sanctions packages restricted but did not sever Russian supply flows, as documented in [EU banned Murmansk port transactions but Russian nickel still reaches Western markets; Nornickel's Q1 output fell sharply and it accelerated China copper JV talks](/en/n/nornickel-murmansk-china-2026). ## Current state As of early 2026, gallium's Western spot price sits near US$2,269/kg versus US$246/kg inside China, a nine-fold premium, while germanium's equivalent gap is approximately 130%, both detailed in [Gallium hit $2,269/kg and germanium $6,150/kg in the West as China's export controls created a permanent East-West price split](/en/n/gallium-germanium-bifurcation-2026). Antimony and tungsten remain supply-constrained: a US ban on Chinese-sourced tungsten in defence procurement takes effect in January 2027, and Almonty Industries' Sangdong mine in South Korea, which targets 40% of ex-China tungsten supply, reached Phase 1 commissioning in 2026, as covered in [Antimony supply shortages persist after a 2,600% price spike; tungsten APT surged 557% as Almonty commissioned South Korea's Sangdong mine](/en/n/antimony-tungsten-controls-2026). On platinum group metals, the World Platinum Investment Council forecasts a fourth consecutive annual platinum market deficit for 2026, at 297,000 troy ounces, while palladium faces the opposite trajectory as hybrid and petrol catalysts gradually shift toward platinum substitution. ## Relationships The six metals divide into two functional clusters. Gallium, germanium, antimony and tungsten are China-controlled industrial inputs. Gallium and germanium feed III-V compound semiconductors, including gallium arsenide and gallium nitride, used in 5G chips, defence radar and power electronics. Antimony hardens lead in military ammunition and acts as a flame retardant in electronics and battery separators. Tungsten, the densest stable metal, is indispensable for armour-piercing penetrators and precision cutting tools. Platinum and palladium belong to the platinum-group metals complex: South Africa provides roughly 75% of global platinum mine supply and Russia provides 40-45% of palladium. Both serve as autocatalysts that convert exhaust gas in petrol and diesel engines. The palladium-to-platinum substitution dynamic is material: automakers shifted heavily toward palladium in petrol catalysts during Russia's 2009-2014 supply uncertainty, then began reversing toward platinum as palladium prices surged above US$2,800/troy oz in 2022. Nornickel's accelerating pivot toward Chinese partnerships, including copper JV negotiations with Xiamen C&D, is reshaping palladium trade flows. ## What to watch The near-term questions are whether China's June 2026 export-control tightening, which added whistleblower rewards and mandatory end-user vetting to all controlled gallium and germanium shipments, causes measurable production disruptions at Western semiconductor fabs before alternative supply from US Department of Energy-backed domestic recovery and Canadian and South Korean separation projects comes online by late 2027; whether US defence prime contractors can qualify Almonty's Sangdong tungsten ore before the January 2027 procurement ban takes effect; whether palladium's structural surplus deepens after 2027 as petrol-vehicle autocatalyst demand softens, depressing prices to the point where Russian palladium exports lose geopolitical leverage; and whether the platinum deficit deepens further as South African mining costs rise and cost pressure at Sibanye-Stillwater's Stillwater mine in the US state of Montana continues. The autocatalyst substitution rate, driven by petrol-vehicle sales in China, India and Southeast Asia, will be the key variable across all six metals. ## Regional takes (batched by bias / lens) ### official record - **US Geological Survey** (United States, en) — USGS Mineral Commodity Summaries 2026 gallium chapter; records China supplying approximately 98% of global primary gallium in 2024, US DoE announcing up to US$6 million for domestic supply-chain development, and export-control impacts on Western pricing.
