Rare Earths Explained Simply: Why the U.S. Still Depends on China for Critical Minerals in 2025

Rare earths aren’t rare — the challenge is refining them. China invested for decades to master the process while others moved away from it.

Everyone’s talking about tariffs, but the real power move in global trade isn’t taxes. It’s minerals. Specifically, rare earths.

They’re the invisible backbone of everything modern — electric vehicles, chips, wind turbines, and fighter jets. Yet few people really understand what they are, why they matter, and why the United States still depends on China to get them.

Let’s explain it simply.

1. Rare Earths Are Not Rare

Despite the name, rare earths are not actually rare. There are 17 metallic elements in this group, and they’re scattered across the world — including in the U.S. and Australia.

The “rare” part refers to the fact that their ores are low in concentration. You can find them almost anywhere, but never in high enough amounts to make mining and refining easy or cheap.

And that’s where China stepped in.

2. Refining Rare Earths Is Dirty, Toxic, and Expensive

Refining rare earths isn’t like digging up gold. It’s a messy, chemical-heavy process that produces radioactive waste and consumes huge amounts of water and power.

Most developed economies gave up refining decades ago because the pollution wasn’t worth the cost. The U.S., for example, shut down most of its refining facilities in the 1990s after environmental and cost concerns made them unsustainable.

China didn’t stop. It doubled down.

Over the last 30 years, China invested heavily in refining technology, built massive industrial zones for separation and purification, and absorbed the environmental cost others avoided. Today, China is the only country that can refine all 17 rare earth elements at commercial scale.

3. China’s Unique Advantage: Scale, Patents, and a Closed-Loop System

China’s rare earth dominance isn’t just about mining. It’s about the entire ecosystem.

According to data from the World Intellectual Property Organization (WIPO) and China’s National Intellectual Property Administration (CNIPA), Chinese entities hold over 8,000 active patents related to rare earth refining, processing, and magnet manufacturing.

That’s more than 60% of all rare earth-related patents worldwide, and more than the United States, Japan, and Europe combined.

China also has lower energy and labor costs, and — most importantly — a domestic industrial base big enough to use everything it refines.

The byproducts from rare earth refining don’t go to waste in China. They’re turned into materials for batteries, magnets, and semiconductors. In most other countries, those byproducts would just become costly waste.

This is why no other nation can currently match China’s efficiency or pricing. It’s not just resources — it’s a full supply chain.

4. Why the U.S. Can’t Just Build Its Own Facilities

The U.S. has reserves and one active rare earth mine in California, but most of that ore is still shipped to China for refining.

Building new refineries in the U.S. isn’t simple. It requires massive capital, radioactive waste management, and years of environmental review. In practice, that means new facilities might not be approved until after the next election cycle — and political timelines rarely align with industrial ones.

It’s not about lack of will. It’s about the realities of regulation, cost, and public resistance to radioactive processing in local communities.

5. Can the U.S. or Its Allies Buy from Somewhere Else?

Not really.

Countries like Australia, Myanmar, and several African nations mine rare earth ores, but most of them still send their materials to China for processing. That’s where the technology, patents, and refineries are.

Even if the U.S. buys from Australia or Canada, the middle step — refining — almost always involves China. That’s the chokepoint.

Until another country builds a full refining chain and downstream industries to absorb the byproducts, there’s no true alternative.

6. The Real Pain Point: Politics and Corporate Power

For Washington, this isn’t just a trade problem. It’s structural.

The U.S. depends on China for materials used in EVs, chips, and defense technology. But changing that means long-term investment, higher costs, and a willingness to take on pollution and regulation battles at home.

That’s a tough sell politically. Especially when large corporations — which hold major lobbying power in Washington — prefer short-term fixes over long-term industrial rebuilding.

So even as tariffs rise, the rare earth supply chain still runs through China. And that’s not something you can change with a policy tweet.

7. Final thought

Rare earths aren’t rare. What’s rare is China’s ability to refine them at scale, manage the waste, and integrate every stage of production into a single ecosystem.

That’s why every time Beijing adjusts its rare earth policies, global markets react. It’s not about politics. It’s about structure, capacity, and time — three things that can’t be replicated overnight.
