Electronic chemicals: the barrier is ppb and an 18-month qualification, not capacity

The growth story is attractive: semiconductor-grade chemicals reached roughly USD 54.2 billion in 2025 and are forecast to double to USD 108.68 billion by 2032, a 10.45% CAGR. So the obvious question is why not simply build a line and enter.

The answer sits in two unglamorous numbers.

Number one: 50% conversion

Purifying from industrial to electronic grade can yield as little as 50%. Two tonnes of feedstock may produce one tonne meeting electronic-grade spec — the rest is cost, not product. That ratio directly sets unit economics, and it worsens as you climb purity grades (G3 to G4 to G5).

More importantly, the ratio depends heavily on process detail and equipment cleanliness and is hard to replicate by buying an off-the-shelf line. It behaves more like a capability accumulated through long debugging.

Number two: a qualification longer than a year

Entering a fab supply chain takes multi-stage qualification, typically beyond a year: small-batch sampling and physical-chemical confirmation, then line compatibility validation, then commercial supply talks. Fail any stage and you restart.

This leads to a counterintuitive conclusion: capacity is not the moat — it can be the burden. Capacity earns nothing during qualification; it only depreciates. The real gate is surviving the qualification period, and the cash flow and process team that make that possible are scarcer than buildings.

AI changes consumption intensity, not the entry rules

AI compute investment genuinely lifts demand: HBM and GPU cluster expansion materially raised chemical consumption per wafer in cleaning, deposition and etch, while sub-3nm multi-patterning raises material value per die.

But that changes volume, not the rules. Qualification is still long, conversion is still low. Growth simply enlarges the payoff for whoever already passed.

Reading import substitution

• Rising domestic share in specialty gases and wet chemicals is real, but segment it: fluorinated etch gases and some precursors move fast, while high-end doping gases and photoresists stay concentrated.
• To judge whether a company is worth tracking, look at which grades it is qualifying and at what stage — not at its planned capacity.
• PFAS restrictions force reformulation. Short term that is a cost; it is also one of the few windows where regulation resets an incumbent's head start.
