Trump is already promising new tariffs, clouding the outlook for business owners after the high court’s decision.

The Supreme Court’s decision to strike down many of Donald Trump’s tariffs came as a relief to many small-business owners struggling under the weight of higher prices. But uncertainty still reigns as the administration pushes ahead with other kinds of tariffs and companies figure out if they will get refunds.

“The administration framed these tariffs as strength,” Richard Trent, the executive director of Main Street Alliance, an organization which represents more than 30,000 U.S. small businesses, said in a statement to NBC News. “What our members experienced was chaos. Rates jumping overnight. No phase in. No planning horizon.”
