Nobody talks about sulfuric acid. It doesn’t have a ticker symbol. There’s no ETF tracking chlorine futures. Ammonia doesn’t appear on financial television. These aren’t glamorous commodities. They’re industrial reagents — the invisible inputs that make virtually every other industrial process possible.
And they are chokepoints just as strategic as any rare earth metal.
Craig Tindale uses an analogy that cuts through quickly: his supercar with a missing titanium bolt on the steering rack. Perfect condition everywhere else. Polished, maintained, beautiful. Couldn’t be driven. One missing component — not a glamorous one, not an expensive one — immobilized the entire system.
Sulfuric acid is that bolt for copper mining. You literally cannot refine copper without it. It’s used in heap leach operations to dissolve copper from ore, and in electrowinning to deposit refined copper from solution. No sulfuric acid, no refined copper. Simple as that. The United States has some domestic sulfuric acid production. It isn’t sufficient for a reindustrialized economy at scale, and significant portions of the supply chain for its precursors run through systems that aren’t fully domestically controlled.
Helium is the bolt for semiconductor fabrication. Taiwan Semiconductor — the foundry that makes the chips that run Nvidia’s AI accelerators, Apple’s processors, and most of the advanced semiconductors in Western defense systems — requires helium for its fabrication processes. Helium is a non-renewable resource extracted as a byproduct of natural gas production. Supply is geographically concentrated. Disruption of helium supply doesn’t slow chip production. It stops it.
Chlorine and ammonia serve equivalent roles across a range of chemical processing industries. Their supply chains are poorly documented in mainstream industrial security analysis.
The point isn’t to generate panic about any specific reagent. The point is that any serious reindustrialization audit has to go all the way down the stack — past the finished products, past the components, past the materials, down to the process chemicals that make the materials processable. At every level of that stack, there are dependencies that no one in Washington is systematically tracking. Until they are, the reindustrialization program has blind spots that will bite.
