Suzhou Jinhong Gas — AI supply-chain exposure

Suzhou Jinhong is a Chinese industrial- and specialty-gas producer that supplies the ultra-high-purity ammonia, hydrogen and nitrous oxide that semiconductor and display fabs consume in deposition, etch and cleaning steps. These bulk and specialty gases are unglamorous but non-optional — a fab cannot run a process without them, and tight purity specifications make suppliers hard to swap once they are qualified. That qualification lock, combined with proximity to a growing base of domestic fabs, is what gives an approved gas vendor durable, sticky positioning in the chain.
