News	April 11, 2026 - Dongjin Semichem plans to begin operations at its semiconductor materials plants in Texas as early as the second quarter, following delays of nearly two years, supported by new orders from Samsung Electronics' foundry business. The company said on April 9 it aims to start operations at facilities located in Killeen and Plainview, near Taylor, Texas, between the second and third quarters. The Killeen plant, operated by its subsidiary Dongjin Semichem Texas, produces semiconductor thinners—essential materials used to remove photoresist from wafer edges during chip manufacturing. The Plainview facility produces high-purity sulfuric acid and is operated by DSM Semichem, a joint venture with Samsung C&T and U.S.-based Martin. Dongjin Semichem holds a 70% stake and leads operations, while Samsung C&T handles sales and Martin supplies raw materials. At full capacity, each plant is expected to generate annual revenue of about 70 billion to 80 billion won, implying up to 150 billion won ($110 million) in additional revenue from the two sites combined. Utilization rates are expected to rise gradually in line with customer ramp-up schedules. Dongjin Semichem decided in 2022 to establish its Texas operations to support Samsung Electronics' foundry expansion in Taylor. The thinner plant was built specifically to supply Samsung's foundry, with Killeen located about an hour's drive from the Taylor site. The company said it invested about 260 billion won in the Texas facilities, with roughly $100 million allocated to each plant. Construction was completed in mid-2024, but mass production was delayed due to a slowdown in customers' foundry businesses. Momentum has since improved after Samsung Electronics secured global big tech clients, including a long-term contract reportedly worth 23 trillion won to supply Tesla's AI6 chips, accelerating the normalization of its Taylor fab. Dongjin Semichem is now preparing to supply materials accordingly. For the sulfuric acid plant, TSMC has been secured as a key customer. Following sample supply and testing, full-scale deliveries are expected to begin in the second half of this year. A Dongjin Semichem official said the company expects mass-production revenue from both Texas plants to begin in the second half, adding that while initial ramp-up will be gradual, each facility could generate annual sales of 70 billion to 80 billion won at full capacity. March 28, 2025 - Governor Greg Abbott today announced that the sixth Texas Semiconductor Innovation Fund grant of $7.87 million has been extended to DSM Semichem LLC (DSM) for an expansion of their specialty materials and chemicals facility in Plainview. This expansion brings DSM’s total capital investment in the facility to $176 million and creates 40 new jobs. “Texas is making strategic investments to ensure the stability of critical domestic supply chains for the technologies that fuel our economy,” said Governor Abbott. “This $176 million total capital investment by DSM to construct and expand its facility in Plainview will double their production volume of specialty materials essential for semiconductor manufacturing in Texas. It will also create 40 good-paying jobs for Texans in a high-demand industry. By working together to meet the rising demand for chip production, Texas will continue to lead the nation as we build a stronger, more prosperous Texas than ever before.” DSM, a joint venture of Dongjin USA, Samsung C&T America, and Martin ELSA Investment LLC, produces electronic-level sulfuric acid (ELSA). DSM’s ELSA is a highly pure form of sulfuric acid needed for its ability to clean wafers and not leave any residual impurities or unidentifiable particles, a critical step in manufacturing chips in high-performance computing, 5G, Al, and defense applications. “DSM Semichem is honored to receive a $7.87 million grant from the Texas Semiconductor Innovation Fund,” said DSM Semichem LLC Managing Director Tae Yong An. “This funding will accelerate the expansion of our electronic-level sulfuric acid plant in Plainview, enabling Texas to produce the highest quality ELSA in America and meet the increasing demand of domestic leading-edge fabs. DSM will establish Texas as a central semiconductor material production hub and strengthen the U.S. semiconductor supply chain.” “This investment is a big win for Texas and a testament to our state’s leadership in securing critical supply chains,” said Senator Charles Perry. “DSM’s expansion in Plainview strengthens our semiconductor manufacturing capabilities, bolsters national security, and brings high-quality jobs and major capital investment to West Texas. By supporting homegrown production of essential materials, Texas is ensuring its role as the backbone of American innovation and economic strength.” “Texas continues to lead the way in securing our nation’s semiconductor supply chain, and this investment in Plainview is proof of that leadership,” said Representative Ken King. “DSM’s expansion will create good-paying jobs, strengthen our local economy, and ensure that materials for chip production are made right here in House District 88. I appreciate Governor Abbott’s commitment to keeping Texas at the forefront of semiconductor manufacturing, and I’m proud to support strategic investments that bring opportunity to our region.” Governor Abbott signed into law the Texas CHIPS Act in 2023 to establish the Texas Semiconductor Innovation Fund, a performance-based incentive program to encourage the continued leadership of Texas in semiconductor research, design, and manufacturing, as well as the Texas Semiconductor Innovation Consortium. These programs, administered by the Texas CHIPS Office, a newly formed division within the Governor’s Texas Economic Development & Tourism Office, are designed to leverage Texas’ investments in the semiconductor industry, encourage semiconductor-related companies to expand in the state, further develop the expertise and capacity of Texas institutions of higher education, and maintain the state’s position as the nation’s leader in semiconductor manufacturing. July 24, 2024 - DSM Semichem LLC, in which Samsung C&T Corporation's Trading Division (hereinafter referred to as Samsung C&T Corporation) is participating, held a ceremony to mark the completion of its high-purity sulfuric acid plant in Plainview, Texas, USA on the 15th. DSM Semichem is a joint venture established in September 2022 by Samsung C&T, Dongjin Semichem, and Martin Midstream, Inc. to address the growing demand for semiconductor materials resulting from the expansion of semiconductor production in the United States. Samsung C&T is responsible for customer development, product sales, and marketing, while Dongjin Semichem, the joint venture, handles production and operations, and Martin Midstream provides raw materials and infrastructure. The recently completed DSM Semichem Plainview plant is a manufacturing facility with an annual production capacity of 24,000 tons of sulfuric acid and is scheduled to begin production in August of this year. The completion ceremony was attended by Samsung C&T President Lee Jae-eon, Dongjin Semichem Vice Chairman Lee Jun-hyeok, and Martin Chairman Ruben S. Martin III.

Construction is estimated to be completed in May of 2024. October 19, 2022 - Martin Midstream Partners announced today that, through an affiliate Martin ELSA Investment LLC, it has entered into definitive agreements with Samsung C&T America, Inc. and Dongjin USA, Inc., an affiliate of Dongjin Semichem Co., Ltd., to form DSM Semichem LLC. DSM will produce and distribute electronic level sulfuric acid. By leveraging the existing assets of MMLP located in Plainview, Texas and installing additional facilities as required, DSM will produce ELSA that meets the strict quality standards required by the recent advances in semiconductor manufacturing. In addition to owning a 10% non-controlling interest in DSM, the Partnership will be the exclusive provider of feedstock to the ELSA facility. MMLP, through its affiliate Martin Transport, Inc., will also provide land transportation services to end-users of the ELSA produced by DSM. Bob Bondurant, President and Chief Executive Officer of Martin Midstream GP LLC, the general partner of MMLP stated, “We are excited to partner with Samsung C&T America, Inc. and Dongjin USA, Inc. in this unique opportunity to capitalize on the diverse and complimentary skillsets, operating expertise, and vast market knowledge of the three parties. The new facilities will incorporate technology currently being utilized to produce ELSA in Taiwan, which exceeds the quality of sulfuric acid being produced in the United States today. “This strategic alliance allows the Partnership to capitalize on our existing asset base to participate in the manufacturing and transportation supply chain of the most advanced and power-efficient chip technology to date. ELSA supply presently sourced in the U.S. does not meet current domestic demand, and with announced new fabrication and existing fabrication facility expansions, we anticipate an attractive market for the ELSA produced in Plainview.” Assuming growth capital investments of approximately $20 million, the Partnership expects to realize annual distributable cash flow of $5 to $6 million from both the improvements to the existing assets and its interest in DSM. The ELSA facility is estimated to start-up in the first quarter of 2024. The Partnership will fund the capital improvements and the contribution to DSM through a long-term land lease and using available capacity under its revolving credit facility. May 6, 2010 - In the first quarter 2010, our Sulfur Services segment experienced an outage at our sulfuric acid production plant for most of the quarter. This negatively impacted our distributable cash flow by approximately $2.4 million. Although not forecasted or planned, the plant did fully incorporate a scheduled maintenance turnaround previously slated for the fourth quarter of 2010 while out of operation. This should improve cash flow later in the year during the time that the turnaround was previously planned. The plant has been operational since March 5, 2010 and is currently at full production.
