The global demand for ultra-high purity anhydrous hydrogen chloride (HCl) gas is on the rise post-pandemic, driven by a surge in semiconductor fabrication sites in countries like the U.S., India, and Europe. The market, valued at US$ 3.6 billion in 2022, is expected to grow at a steady CAGR of 5.4% to reach US$ 5.7 billion by the end of 2031. In India, significant investments in semiconductor fabs, including the approval of three new semiconductor plants, are propelling the market forward. The U.S. semiconductor industry is receiving funding through initiatives like the CHIPS and Science Act, encouraging domestic manufacturing and creating opportunities for anhydrous HCl suppliers. This trend is reflective of a global push towards self-sufficiency in semiconductor production to overcome chip shortages experienced during the pandemic. Asia Pacific stands out as the leading region in semiconductor investments, with India's semiconductor capabilities on the rise. Additionally, the Middle East & Africa region is witnessing market growth due to petrochemical projects, with major players like BASF SE and Linde plc actively involved in ultra-high purity anhydrous HCl production. Overall, the increasing demand for ultra-high purity anhydrous HCl gas underscores the crucial role it plays in the semiconductor industry and the lucrative opportunities it presents for market players across different regions.
