A U.S. subsidiary of Taiwan-based Ta Chen International has signed an agreement to acquire Arconic's (NYSE:ARNC) Texarkana, Texas, aluminum rolling mill for $300 million and other considerations. Ta Chen had announced earlier in the year that it was planning to spend $1 billion on acquisitions or organic growth in the U.S., and this appears to be the company's first step in that direction in response to tightening aluminum supply due to Section 232 and 301 trade tariffs.
