Shoppers at Midtown Global Market are feeling the impact of the Trump tariffs this weekend.

“I’m changing my habits and buying less,” says Brenda Blakey from Minneapolis. “A lot less.”

On Friday, the U.S. Supreme Court struck down most of the Trump levies.

The president quickly announced a global 10% tariff, then Saturday, upped that to 15%.

ABC News reports that 15% rate is the upper limit allowed under Section 122 of the Trade Act of 1974.

“Other alternatives will now be used to replace the ones that the court incorrectly rejected,” Trump told reporters. “We have alternatives, great alternatives, could be more money. We’ll take in more money, and we’ll be a lot stronger for it.”  

But John Spry, a finance professor at the University of St. Thomas, says the rapid-fire tariff changes will likely trigger sticker shock.

“For the everyday American, you’re going to be worse off, because we have a lot of uncertainty,” he notes. “So imported apparel, fruits and vegetables that we import, particularly in Minnesota in February or March, those now have a 15% cost.”

That uncertainty is impacting Minnesota family farms.

“If you’re a young beginning farmer, without much equity, it’s going to be pretty hard to survive this,” declares Gary Wertish, the president of the Minnesota Farmers Union.

The Minnesota Department of Agriculture says the state’s more than 67,000 farms export $10 billion annually of soybeans, corn and other produce to China, Mexico, Canada and other countries.

Experts say China has turned to other countries as the Trump tariffs kicked in, and it’s uncertain what that 15% rate will do.  

Wertish says growers also import fertilizer from Canada, and machine parts from Europe, Mexico, and China — another reason for keeping tabs on those tariff rates.  

“You know the farmers are like, ‘We’re in an economic crisis now,’” Wertish says. “Working with their lenders to get their line of credit and see if they can even operate next year.”

Then there’s Plymouth entrepreneur Jack Tomczyk.  

He invented a plastic collar for a Shop-Vac remote control.

But the controller itself, from China, cost more than he expected.

“Like this should cost $3,” Tomczak declares. “But after all the tariffs and some shipping, it ended up costing $10. And that’s a lot of money out the door before I had made any money on my product.”

Experts say the 15% tariff can only last for 150 days without congressional approval.

It could take effect as early as Tuesday.

Tomczyk says he ordered 700 controllers, costing him around $7,000.

He estimates about $4,000 to $5,000 of that came from tariff charges.

His takeaway?

“It’s not a good environment to plan, when things change so frequently,” Tomczak says. “So, it’d be nice to have a consistent system of lower or no tariffs.”
