Welcome To ChemAnalyst
OCI Holdings, a leading South Korean chemical manufacturer headquartered in Seoul, has unveiled plans to double its annual polysilicon production capacity from 35,000 metric tons to 70,000 metric tons by 2029. The expansion reflects the company’s strategy to capitalize on the rapidly growing demand for high-purity polysilicon from the U.S. artificial intelligence, semiconductor, solar, and space sectors.
The investment is aimed at strengthening OCI’s position in the global polysilicon supply chain, particularly as the United States continues to expand AI infrastructure and renewable energy deployment. Increasing demand for AI data centers has accelerated the need for reliable electricity generation, creating additional opportunities for solar energy projects that rely heavily on polysilicon-based photovoltaic components.
Earlier this year, reports indicated that OCI TerraSus, the company’s Malaysia-based subsidiary, was engaged in discussions with SpaceX regarding a long-term agreement to supply polysilicon. Such a partnership would support the growing material requirements of the aerospace industry while reinforcing OCI’s role as a strategic supplier of advanced materials.
OCI also announced that it has established a U.S.-focused non-prohibited foreign entity (PFE) solar supply chain. This supply network connects OCI TerraSus with NeoSilicon Technology (NST), a wafer manufacturer based in Vietnam. The initiative is designed to provide a compliant and secure supply chain for customers in the U.S., helping the company navigate evolving trade policies and sourcing regulations.
The company strengthened this strategy by acquiring a 65% stake in NeoSilicon Technology in October 2025, making OCI the majority shareholder and principal supplier of raw materials. NST currently operates wafer manufacturing capacity of approximately 2.7 GW and intends to expand it to 11.5 GW by 2029. Commercial shipments to customers in the U.S. are expected to commence next year, supporting the country’s expanding renewable energy market.
OCI Holdings Chairman Lee Woo-hyun stated that the continued growth of AI data centers is reinforcing the momentum of solar energy adoption in the U.S. energy sector. He added that the company’s differentiated non-PFE supply chain provides a competitive advantage, enabling OCI to increase investments across the solar value chain while adapting to changes in global supply networks.
In another significant development, OCI TerraSus recently secured a $125 million loan from the International Finance Corporation to establish a semiconductor-grade polysilicon manufacturing facility in Sarawak, Malaysia. The project is expected to become Southeast Asia’s first facility dedicated to producing semiconductor-grade polysilicon, further strengthening OCI’s presence in high-value materials and supporting future demand from semiconductor, electronics, renewable energy, and advanced technology industries.
Impact on Product and ChemAnalyst Chemical Prices
OCI Holdings’ capacity expansion is expected to strengthen the global supply of high-purity polysilicon, improving raw material availability for solar wafers, photovoltaic modules, semiconductor components, and advanced electronics. Over the medium term, increased production could ease supply constraints and moderate polysilicon prices, particularly as new capacity becomes operational. For chemical commodities tracked by ChemAnalyst, the direct impact is expected to remain limited. However, higher demand for semiconductor-grade silicon and solar manufacturing materials may provide gradual support to specialty silicon chemicals, chlorosilanes, hydrochloric acid, and related upstream intermediates, while broader petrochemical prices are likely to remain largely stable due to balanced global supply conditions.
