President Donald Trump's shifting tariff policy is throwing the U.S. business community into deep uncertainty, raising daily costs for American consumers and dimming the national economy's growth prospects, according to Gene Seroka, executive director of the Port of Los Angeles, the country's largest container port.

Seroka told local media that corporate executives across the U.S. supply chain are deeply concerned about making long-term plans amid disruptions caused by Trump's trade policy changes.

Trump announced Saturday that he is raising his global tariffs from 10 percent to 15 percent, a day after the U.S. Supreme Court ruled that most of the tariffs he has imposed since April 2025 were unlawful.

"It's really tough to plan strategically, longer-term, for talent, investment and technology, when you don't know what the rules are going to be," Seroka said.

He added that U.S. economic performance in the fourth quarter of 2025 was "also off," and that last year recorded the largest trade deficit since 1960.

"Companies have hit the pause button, not making deep investments because they don't know what policy changes will be shifting," he said, adding that the tariffs would most likely be borne by America's own consumers and companies.
