TLDR
China refines somewhere between 59% and 65% of the world’s germanium, depending on whether you’re counting mined output, refined metal, or export volume — the numbers move depending on which stage of the supply chain you’re measuring. Belgium and Canada split most of what’s left, Belgium mostly through recycling rather than mining. Russia, the United States, Japan, and Germany each hold single-digit slivers. None of that is static: China restricted exports in 2023, banned shipments to the US outright in December 2024, then suspended that ban through November 2026 as part of a broader trade truce. If you’re trying to understand germanium supply risk right now, the country you should be watching isn’t a producer at all — it’s whoever’s negotiating with Beijing this quarter.
Who Produces Germanium, and How Much
There’s no clean, single-source ranking of germanium producers, and that’s worth saying up front — this is a byproduct metal, recovered as a side effect of mining something else, and different agencies count it differently. Here’s a working breakdown built from U.S. Geological Survey data and Chinese customs figures:
| Country | Estimated share of world supply | How it gets produced |
|---|---|---|
| China | ~60-65% | Byproduct of zinc smelting and coal-fired power generation |
| Belgium | Largest producer outside China | Recycling scrap, residues, and process waste — little to no mining |
| Canada | Second-largest primary producer | Byproduct of zinc ore refining at a single integrated smelter |
| Russia | Small but strategically watched | Byproduct of coal ash processing in the Far East |
| United States | ~3% of world supply | Imported concentrate plus recycled scrap, no domestic mine output |
| Japan | Minor refiner | Imported feedstock, refined to optical-grade purity |
| Germany | Minor, historic producer | Byproduct of legacy zinc smelting operations |
USGS put global mined-and-recycled production at roughly 230 metric tons in a recent year, with China responsible for around 145 of those tons. Chinese customs data tracked by the Center for Security and Emerging Technology pegs China’s share of refined germanium closer to 59% for 2023. Same metal, different stage of the pipeline, different percentage. Neither number is wrong.
Where the Metal Actually Comes From
No one mines germanium ore. There’s no germanium equivalent of a copper pit or a lithium brine — it doesn’t concentrate anywhere near densely enough to justify digging for it on its own. Instead, it rides along with two other extraction processes.
The bigger source, accounting for something like 70-75% of world supply, is zinc. Germanium substitutes for zinc atoms inside sphalerite, the main zinc ore mineral, at concentrations low enough that a smelter has to process enormous volumes of ore to recover a commercially useful amount. Canada’s Teck Resources runs the process at its Trail smelter in British Columbia — one of the only fully integrated zinc-to-germanium operations outside China.
The other 25% or so comes from coal. Certain coal seams, most notably in China’s Yunnan province and in Russia’s Sakhalin region, carry germanium bound up in the organic material. Burning that coal concentrates the metal in the fly ash, which then gets chemically stripped out. It’s a strange origin story for a material that ends up inside fiber-optic cable and infrared satellite optics — dug up as fuel, salvaged from the ash.
China’s Grip on the Market
China’s dominance isn’t really about geology. Its zinc-ore germanium content isn’t unusually rich, and other countries have comparable coal seams. What China has is scale, decades of state-backed refining infrastructure, and — critically — the willingness to treat germanium as leverage rather than just a commodity.
That became explicit in mid-2023. On July 3, China’s Ministry of Commerce announced that exporters of germanium and gallium would need a government license starting August 1, framed as a national-security measure. The U.S. International Trade Commission’s briefing on the controls noted that China controlled roughly 83% of global germanium supply chain capacity at the time the licensing regime took effect — a figure that reflects China’s grip across refining and processing, not just mine output.
The licensing requirement wasn’t a full ban, but it worked like a slow valve. Buyers outside China spent the second half of 2023 scrambling to lock in inventory before the rules tightened further, and prices moved accordingly.
The Non-China Producers
Six other countries show up in most production tallies, and they’re not interchangeable — each occupies a different niche rather than competing head-on with China’s volume.
Belgium doesn’t really mine anything. Its position comes from recycling: reclaiming germanium from scrap infrared optics, spent semiconductor material, and industrial residue. It’s the closest thing the West has to a circular-supply model for this metal.
Canada is the only Western country running a genuine mine-to-metal pipeline, via the Trail smelter’s zinc-to-germanium recovery. It’s a meaningful chunk of non-China primary supply, though nowhere near China’s scale.
Russia produces from coal ash in its Far East, and its output gets treated as strategically sensitive given the defense applications of germanium in infrared optics — night-vision equipment, thermal imaging, that kind of hardware.
The United States has essentially zero domestic mine production. Indium Corporation refines imported concentrate and recycled material domestically, which is enough to matter for defense supply chains but not enough to make the US self-sufficient — it’s roughly 3% of world supply, all downstream of imported feedstock.
Japan and Germany round out the list as minor refiners, both processing imported material rather than extracting their own, focused on the high-purity end of the market — semiconductor substrates and specialty optics.
How the Export Controls Rewired the Market
The August 2023 licensing rules turned out to be an opening move, not the endpoint. Prices climbed through the back half of 2023 as buyers front-loaded orders, and by 2024 germanium metal was trading at more than double its pre-controls price.
Then, on December 3, 2024, China escalated: a full export ban on germanium, gallium, and antimony shipments specifically to the United States, announced one day after Washington tightened its own controls on advanced chip technology sold to China. It read as retaliation because it was retaliation — germanium and gallium sit at the center of semiconductor manufacturing, and China had the leverage to make that point directly.
That ban didn’t last as policy, at least not for now. In November 2025, China suspended the restriction on gallium, germanium, and antimony exports to the US, according to reporting from CNBC, with the suspension running through November 27, 2026 as part of a broader trade détente. Buyers got relief, but not certainty — a suspension is not a repeal, and the license requirement from 2023 never went away.
Germanium-Producing Countries Through 2026
Watch two things if you’re tracking this market rather than just reading about it once. First, whether the November 2026 expiration of the current suspension gets extended, allowed to lapse, or replaced with something tighter — that date is a real deadline, not a formality. Second, whether Western capacity actually grows in response, rather than just getting talked about. Canada’s Trail smelter and Belgium’s recycling capacity are the two levers non-China buyers have, and neither scales quickly. Refining germanium to semiconductor-grade purity takes specialized infrastructure that doesn’t get built in a fiscal year.
The germanium-producing countries list itself probably won’t change much by 2026 — this isn’t a metal where new entrants show up overnight, since it depends entirely on existing zinc and coal infrastructure rather than dedicated mines. What will keep changing is how much leverage China chooses to exercise over the countries already on that list, and how much the rest of the world manages to build around it in the meantime.
