Rin Kagaku Kogyo diversifies imports of yellow phosphorus to ensure semiconductor supply chain security

Rin Kagaku Kogyo is diversifying its supply sources for yellow phosphorus, a critical material for semiconductor manufacturing. This move aims to enhance economic security and mitigate risks of supply shortages for phosphorus-based chemicals used in chip production.
Context
On March 15, 2026, Japanese chemical manufacturer Rin Kagaku Kogyo, a subsidiary of Shikoku Kasei Holdings, announced a strategic diversification of its yellow phosphorus import channels to bolster semiconductor supply chain security. Yellow phosphorus is a critical precursor for electronic-grade phosphoric acid, which is used extensively for cleaning and etching silicon wafers in high-purity chip fabrication. The electronics segment for these phosphorus compounds has seen rapid growth, increasing by over 20% year-on-year as chip geometries shrink to 5nm and below.
This move comes as the global market for electronic-grade phosphoric acid is projected to reach $1.83 billion by 2031. Supply chains for yellow phosphorus have faced significant volatility due to export restrictions from major producers like China and energy-related production halts in regions such as Yunnan. By diversifying its sourcing, Rin Kagaku Kogyo aims to mitigate risks associated with regional dependencies and ensure a stable supply for the semiconductor industry's increasingly stringent purity requirements.
