Sometimes the most important warning isn’t what China puts on an export-control list; it’s what happens around it…
Last week, Reuters reported that some Chinese rare-earth suppliers have simply stopped shipping certain materials to American customers.
Not because every shipment was explicitly banned…
Not because they lacked necessary permission…
But because they were worried about what Beijing might do to them if they continued doing business with U.S. companies.
Think about that for a second…
We’ve reached the point where China doesn’t need to issue a sweeping embargo to disrupt Western access to critical materials.
Sometimes the threat of Beijing’s displeasure is enough.
And that should scare the hell out of anyone responsible for America’s industrial supply chain.
Because if we wait until China officially shuts the door on a mineral before developing alternatives, we’ve already waited too long.
The Pattern Is Getting Hard to Ignore
This didn’t start last week…
Over the past few years, China has steadily demonstrated how much leverage it possesses over the raw materials that make the modern economy work.
First came controls on gallium and germanium…
Then graphite…
Then antimony…
Then, in February 2025, Beijing expanded its export-control regime to include tungsten, tellurium, bismuth, indium, and molybdenum products.
Those restrictions require exporters to obtain licenses and give the Chinese government considerably more control over what leaves the country.
You see, China hasn’t simply thrown a giant switch and banned every pound of tungsten from reaching America, not yet.
But it has built the switch. And it has put its hand on it.
And now we’re learning that the formal rules may not even tell the whole story…
Reuters reported September 4 that some Chinese rare-earth suppliers have refused shipments to U.S. customers because they fear repercussions from Beijing.
The problems have persisted despite diplomatic commitments intended to keep critical-material exports flowing.
That creates what may be an even more dangerous situation than a straightforward ban.
Because businesses can plan around a published prohibition.
It’s much harder to plan around suppliers deciding, one by one, that selling to you simply isn’t worth the political risk.
Tungsten Is Exactly the Kind of Mineral We Can’t Gamble With
And that brings us to tungsten…
There are a lot of critical minerals America would prefer not to lose access to.
But tungsten is one we absolutely cannot afford to lose…
It has the highest melting point of any pure metal. It’s extraordinarily hard, dense, and resistant to heat and wear.
Those properties make it essential to everything from cutting and drilling equipment to aerospace components, semiconductor manufacturing, oil and gas equipment, armor, ammunition, and other defense applications.
And China dominates it.
According to the U.S. Geological Survey, China accounted for roughly 82% of global mined tungsten production in 2024.
That isn’t a competitive advantage; that’s leverage.
And Beijing has already demonstrated that it understands exactly how valuable critical-mineral leverage can be.
Tungsten prices have reflected that increasingly precarious supply situation.
In fact, prices for several strategic minerals have surged amid export restrictions and rising demand, with tungsten prices increasing roughly sixfold from earlier levels.
Markets are sending a message: Supply security matters again.
We Keep Learning the Same Lesson
America has spent decades operating under a simple assumption…
If somebody overseas can produce something cheaper, we’ll buy it from them.
And that works beautifully for T-shirts, but it works considerably less well for materials required to manufacture missiles, aircraft, semiconductors, drilling equipment, and heavy industrial machinery.
Especially when the country dominating the supply chain is also America’s biggest strategic competitor.
And yet we continue treating domestic critical-mineral production like an economics problem instead of a national-security problem.
We debate whether a mine will be slightly more expensive, whether permitting should take a few more years, whether government support distorts the market…
Meanwhile, China spent decades building dominant positions throughout mineral supply chains.
Case in point: China was the world’s leading producer of 39 different mineral commodities in 2023.
And it controls more than 65% of global production for 15 of them.
That didn’t happen accidentally. And China clearly recognizes the strategic value of what it built.
The West needs to recognize it too.
The Ban Doesn’t Have to Come Tomorrow
Here’s the important part…
I’m not telling you China is going to announce a total tungsten embargo tomorrow morning.
Nobody outside Beijing can know that.
What I’m saying is that waiting for an embargo would be insane.
We already know China dominates tungsten production.
We already know Beijing has placed export controls on tungsten products.
We already know China has tightened access to other strategic minerals when geopolitical tensions increased.
And now we know that some Chinese suppliers can become reluctant to sell to American companies even when exports have not been completely prohibited.
How many more warnings do we need?
Maybe tungsten exports continue, maybe licenses keep getting approved…
Maybe Washington and Beijing reach agreements that keep material flowing.
Great. That would buy us something incredibly valuable: time.
And instead of treating that time as proof we don’t have a problem, we should use every minute of it to build alternative supply.
Dig It Here, Process It Here
The obvious answer isn’t to replace Chinese dependence with dependence on some other country halfway around the world.
It’s to rebuild the Western supply chain.
That means finding deposits, permitting mines, building processing capacity, recycling more tungsten, stockpiling strategic material…
And, wherever economically and geologically possible, developing resources in the United States and allied countries.
This isn’t something that can happen after a crisis begins.
You can’t discover a deposit on Monday, permit it Tuesday, build a mine Wednesday, and start supplying defense contractors Thursday.
Mining projects can take years…
Processing infrastructure takes time and capital. Supply chains have to be qualified. Customers have to be secured.
And that means the correct time to develop Western tungsten sources isn’t after Beijing announces another restriction.
It’s now.
The Real Warning from China
That’s what last week’s news should teach us.
The important story isn’t simply that another group of critical materials is becoming harder for Western companies to obtain.
It’s that China has developed so much control over strategic supply chains that even the possibility of government retaliation can influence whether private companies are willing to sell critical materials to Americans.
That should fundamentally change the way we think about mineral security.
Because the next supply cutoff may not begin with a dramatic government announcement.
There may be no press conference, no giant headline declaring a tungsten embargo…
American manufacturers may simply discover that the licenses are taking longer, that certain products aren’t available, that suppliers suddenly aren’t answering the phone.
And then, by the time everyone agrees we have a crisis, the crisis will already be here.
We know where this road leads. China has shown us repeatedly.
The only question is whether we’re smart enough to start building another road before the one we’re driving on gets closed.
