Past the Rare Earth Theater: How China Actually Won the Chip War While You Were Arguing About Gallium

A late-night investigation into the semiconductor supply chain's most boring — and most critical — vulnerability The think tank industrial complex is fighting the last war — the one where controlling the most advanced technology gives you strategic advantage. But in the chemical supply chain, controlling the most mundane technology gives you strategic advantage. And nobody's paying attention. Conclusion: The War That's Already OverSo here I am, 4:53 AM, staring at my fourth cup of coffee and a spreadsheet full of chemical dependency data that should probably be classified, wondering how we got here. "Democracy is the theory that the common people know what they want, and deserve to get it good and hard." — H.L. Mencken The answer is simple: while we were watching the Hollywood version of the chip war — the dramatic export controls, the billion-dollar fab announcements, the congressional theater — China was quietly, methodically winning the real war. Molecule by molecule. Chemical by chemical. Company by company. Runjing Chemical didn't announce their intention to control critical semiconductor chemistry. They just did it. TMAH. TMAC. TEAC. TMAB. Learn those acronyms, because you'll be hearing them in congressional testimony soon enough. Right around the time some senator realizes that we can't make chips without chemicals we don't control, from companies we've never heard of, in supply chains we don't understand. "We are all in the gutter, but some of us are looking at the stars." — Oscar Wilde The beautiful, terrifying irony is that we did this to ourselves. We ignored the boring stuff — the cleaning chemicals, the developers, the mundane molecular machinery that makes modern life possible — because it wasn't sexy enough for congressional hearings or think tank conferences. And now it's too late. By the time you read this blog post (assuming you made it this far), Runjing will be shipping another batch of ultra-pure TMAH to another customer somewhere in the world. Another small step in a very large, very quiet conquest that's already succeeded. The chip war isn't coming. It's over. We lost. We just haven't realized it yet. Sweet dreams.
