Arsenic in the semiconductor supply chain

Arsenic is a semiconductor-critical mineral. In USGS data for 2024, Peru was the largest producer at 27,000 t of a world total of 58,000 metric tons (arsenic trioxide, gross weight, 2024); the next producers were China, Morocco and Belgium. US net import reliance is 100%.

Why it matters downstream

Arsenic sits at the top of the value chain. Materials suppliers consume it first, and every fab, packaging house and device maker below them depends on that supply holding. A producer holding most of world output is the same single-source shape wafergraph flags at the company level.
