Century Aluminum to Construct 1st US Aluminum Plant in More Than 40 Years

The project is expected to create 5,000 direct and construction jobs.

Illinois-based Century Aluminum Co. has entered into a joint development agreement with Emirates Global Aluminium (EGA) to construct the “first new primary aluminum production plant in the United States since 1980,” Century said in a statement on Jan. 26.

Primary aluminum production involves smelting alumina to produce new aluminum metal. This differs from secondary production, in which existing aluminum is recycled.

“The new plant, to be built in Inola, Oklahoma, as previously announced by EGA, is expected to produce 750,000 tonnes of aluminum per year, larger than previously envisioned and more than doubling current U.S. production. The Inola plant will create 1,000 permanent direct jobs at the facility and 4,000 jobs during construction,” Century stated.

“About 85 percent of the aluminum needs of American industries are currently met by imports. The new smelter will expand the domestic supply of this critical mineral and grow the American aluminum workforce, revitalizing U.S. aluminum expertise and know-how.”

According to data from the International Aluminum Institute, China was the largest producer of primary aluminum in 2025, accounting for an estimated 44.2 million metric tons out of the 73.78 million metric tons of global output.

Commenting on Century’s plan to build a U.S. aluminum smelter, White House deputy press secretary Kush Desai said in a Jan. 26 post on X, “President Trump’s tariffs are working.”

Trump’s Tariffs

In March 2025, the Trump administration’s 25 percent tariffs on steel and aluminum imports came into effect. In June, the tariff rate doubled to 50 percent.

At the time, the Aluminum Association, a group representing the U.S. aluminum industry, had struck a cautious tone on the tariffs, saying they would neither increase domestic aluminum output nor support mid- and downstream industries.

In a post on June 5, 2025, the Council on Foreign Relations warned that if aluminum and steel prices were to rise, it could negatively affect industries such as automotive, appliances, electrical, oil and gas, and machinery.

President Donald Trump justified the tariffs in February 2025, a month before the 25 percent tariff took effect, saying they were essential to bolster domestic production, bring jobs back to the United States, and stop other nations from taking advantage of the United States.

“Our nation requires steel and aluminum to be made in America, not in foreign lands,” he said at the time. “This is a big deal, the beginning of making America rich again.”

In August 2025, the federal government announced tariff hikes on more than 400 products, subjecting them to the 50 percent steel and aluminum import tariffs.

The move affected 407 product categories, including furniture, railcars, and compressors.

Jeffrey Kessler, undersecretary of commerce for industry and security, said at the time that the action “expands the reach of the steel and aluminum tariffs and shuts down avenues for circumvention—supporting the continued revitalization of the American steel and aluminum industries.”

Aluminum Plant

Construction of the Inola plant is set to begin by the end of the year, and production is scheduled to kick off by the end of the decade, Century stated.

The plant will be constructed at the industrial park at Tulsa Port of Inola, located on the McClellan-Kerr Arkansas River Navigation System, which connects to the Mississippi River system, providing efficient bulk freight movement.

Once construction is completed, the Inola plant will be the largest ever primary aluminum production plant in the United States.

The plant is expected to drive forward the development of an aluminum-focused industrial hub in the state, which would result in thousands of additional jobs, Century stated.

Under the deal, EGA, the world’s largest “premium aluminum” producer, will own 60 percent of the joint venture, and Century will hold the remaining 40 percent. The plant will use EGA’s “state-of-the-art” EX technology, its next-generation aluminum smelting technology.

Jesse Gary, CEO of Century Aluminum, said that key industries such as aerospace, automotive, construction, and national defense stand to benefit “greatly” from the venture.

“Our partner EGA brings world-class smelting technology and construction expertise that are fast-tracking our collective efforts to realize President Trump’s vision of rapidly increasing domestic primary aluminum production,” he said.

“We are once again proving that President Trump’s leadership is working to spur investment and innovation to revitalize the U.S. aluminum industry, which is essential to our nation’s defense and the economic vitality of working-class communities across the country.”
