The semiconductor industry is witnessing a surge in demand as various companies announce new fabrication sites globally. This growth has led to a significant increase in the demand for ultra-high purity anhydrous hydrogen chloride (HCl) gas. The market, valued at US$ 3.6 billion in 2022, is expected to reach US$ 5.7 billion by 2031, with a steady CAGR of 5.4% according to Transparency Market Research. In India, substantial investments in semiconductor fabs are boosting the market for ultra-high purity anhydrous HCl. The U.S. is also taking steps to enhance its semiconductor capabilities, particularly with the CHIPS and Science Act funding. The chip shortage post-pandemic has prompted countries to invest in domestic semiconductor production, creating opportunities for HCl gas market growth. Anhydrous HCl plays a vital role in semiconductor production, especially in the production of high-quality silicon essential for chip manufacturing. This increased semiconductor demand is fueling the growth of the ultra-high purity anhydrous HCl gas market. Additionally, ongoing refinery projects in the Middle East & Africa are contributing to market dynamics. Key market players, including BASF SE and Air Liquide, are actively involved in the ultra-high purity anhydrous HCl gas industry. Companies are investing in chlor-alkali plants to produce essential chemicals, further boosting the market. The industry outlook remains positive, with a focus on strategic investments to cater to the growing demand in the semiconductor and petrochemical sectors.
