China discovers 35 million tons of a forgotten strategic mineral: Beijing has formidable geopolitical and economic weapon

It’s maybe hard for us to get excited about sand – unless we’re heading off to the Bahamas or somewhere similar for a sunny break – but when that sand is high-purity quartz (referred to simply as HPQ), suddenly you’ve got the makings of a geopolitical power play.

HPQ is the rare, ultra-clean mineral that underpins the global semiconductor and solar industries and it’s exactly what China has just uncovered: two massive deposits totaling over 35 million tons of this strategic resource.

Why is high-purity quartz so important?

For a material most people wouldn’t recognize outside a watch face, HPQ punches far above its weight. This isn’t your average beach grit. With silicon dioxide (SiO₂) content exceeding 99.995% and no trace of iron, titanium, or aluminum, HPQ is one of the cleanest substances on Earth. It’s critical in manufacturing microchips, fiber optics, solar panels – anywhere impurities aren’t just inconvenient but catastrophic.

If you want to grow a flawless silicon crystal, the kind used at the heart of every microprocessor, you need HPQ crucibles to handle the searing heat without contamination. It’s also a must for fiber-optic cables and high-precision optics. Without it, the tech world grinds to a halt.

U.S. supply chain impact

Until now, China imported the bulk of its HPQ – around $1.5 billion annually. Most of it came from the Spruce Pine region in North Carolina, a sleepy town that quietly powered the world’s tech factories. The U.S. supplied roughly 80% of China’s demand, with Norway, Brazil, and India filling in the gaps.

But that dependence ends here, as reported by CCTV News via Global Times.

The discovery of these world-class deposits in Xinjiang and Henan gives Beijing the raw material to supply itself – and potentially, the rest of the world – without relying on anyone else. By securing its own supply, China can potentially undercut U.S. dominance in a material crucial to semiconductors, just as Washington ramps up efforts to rebuild its domestic chip industry. Think of it as Beijing quietly pulling a key thread in the complex web of global tech manufacturing.

What are the geopolitical stakes over HPQ?

This won’t make too many headlines – there are too many war leaks and other scandals dominating eyeballs – but China’s move to control high-purity quartz (HPQ) could chip away at a quiet source of U.S. leverage in tech supply chains. For years, Washington counted on its dominance of this rare material. That edge may now be, ahem, eroding.

China has already classified HPQ as a strategic mineral, alongside rare earths and tungsten, and is building out national infrastructure to refine and manage its own supply. It’s aiming for full independence.

For the U.S. – with Trump locked in ongoing trade disputes and importing around $200 billion in Chinese goods, many heavily taxed – this creates yet another point of imbalance. The trade deficit isn’t getting any smaller.

Could this increase U.S. and China tensions?

China’s grip on rare earths has long frustrated Washington and this is not improving. Adding HPQ to Beijing’s list of controlled resources won’t ease relations, and we can expect more tariffs or rushed attempts at domestic mining, though catching up will be slow and costly.

Europe won’t escape the fallout either. Still reliant on U.S.-led supply chains, Brussels will feel the strain if U.S.-China friction rises over this quietly strategic material. No one is clear how this will evolve.
