DETROIT (AP) -- If Donald Trump makes good on his threat to slap 25% tariffs on everything imported from Mexico and Canada, the price increases that could follow will collide with his campaign promise to give American families a break from inflation.

Economists say companies would have little choice but to pass along the added costs, dramatically raising prices for food, clothing, automobiles, booze and other goods.

The president-elect floated the tariff idea, including additional 10% taxes on goods from China, as a way to force the countries to halt the flow of illegal immigrants and drugs into the U.S. But his posts Monday on Truth Social threatening the tariffs on his first day in office could just be a negotiating ploy to get the countries to change behavior.

High food prices were a major issue in voters picking Trump over Vice President Kamala Harris, but tariffs almost certainly would push those costs up even further.

For instance, the Produce Distributors Association, a Washington trade group, said Tuesday that tariffs will raise prices for fresh fruit and vegetables and hurt U.S. farmers when other countries retaliate.

"Tariffs distort the marketplace and will raise prices along the supply chain, resulting in the consumer paying more at the checkout line," said Alan Siger, association president.

Mexico and Canada are two of the biggest exporters of fresh fruit and vegetables to the U.S. In 2022, Mexico supplied 51% of fresh fruit and 69% of fresh vegetables imported by value into the U.S., while Canada supplied 2% of fresh fruit and 20% of fresh vegetables.

Before the election, about 7 in 10 voters said they were very concerned about the cost of food, according to AP VoteCast, a survey of more than 120,000 voters.

"We'll get them down," Trump told shoppers during a September visit to a Pennsylvania grocery store.

The U.S. is the largest importer of goods in the world, with Mexico, China and Canada its top three suppliers, according to the most recent U.S. Census data.

People looking to buy a new vehicle likely would see big price increases as well, at a time when costs have gone up so much that they are out of reach for many. The average price of a new vehicle now runs around $48,000.

About 15% of the 15.6 million new vehicles sold in the U.S. last year came from Mexico, while 8% crossed the border from Canada, according to Global Data.

Much of the tariffs would get passed along to consumers, unless automakers can somehow quickly find productivity improvements to offset them, said C.J. Finn, U.S. automotive sector leader for PwC, a consulting firm. That means even more consumers "would potentially get priced out of the activity" of buying a new vehicle, Finn said.

Hardest hit would be Volkswagen, Stellantis, General Motors and Ford, Bernstein analyst Daniel Roeska wrote Tuesday in a note to investors. Stellantis and VW import about 40% of the vehicles they sell from Canada and Mexico, while it's 30% for GM and 25% for Ford. GM and Stellantis import more than half of their high-profit pickup trucks from the two countries, according to Bernstein.

If Trump does impose the tariffs in January, the auto industry would have little time to adjust, putting operating profits at risk for the automakers, Roeska said in an email. "A 25% tariff on Mexico and Canada would severely cripple the U.S. auto industry," he said.

The tariffs would hurt U.S. industrial production so much that "we expect this is unlikely to happen in practice," Roeska said.

The tariff threat hit the stocks of some companies that could be particularly hurt, such as auto manufacturers and Constellation Brands, which sells Modelo and other Mexican beer brands in the United States.

But the overall market held relatively steady near records as investors saw Trump's proposal as more of an opening position for negotiations rather than as a definitive policy.

It's not clear how long the tariffs would last if they are implemented, but they could force auto executives to move production to the U.S., which could create more jobs in the long run. But Morningstar analyst David Whiston said in the short term automakers probably won't make any moves because they can't quickly change where they build vehicles.

To move to the U.S., they would have to buy equipment and revamp their parts supply chain, which can take years. "I think everyone is going to be in a wait-and-see mode," Whiston said.

Millions of dollars worth of auto parts flow across the borders with Mexico and Canada, and that could raise prices for already costly automobile repairs, Finn said.

The Distilled Spirits Council of the U.S. said tariffs on tequila or Canadian whisky won't boost American jobs because they are distinctive products that can only be made in their country of origin.

In 2023, the U.S. imported $4.6 billion worth of tequila and $108 million worth of mezcal from Mexico and $537 million worth of spirits from Canada, the council said.

"At the end of the day, tariffs on spirits products from our neighbors to the north and south are going to hurt U.S. consumers and lead to job losses across the U.S. hospitality industry just as these businesses continue their long recovery from the pandemic," the council said in a statement.

Electronics retailer Best Buy said on its third-quarter earnings conference call that it runs on thin profit margins, so while vendors and the company will shoulder some increases, Best Buy will have to pass tariffs on to customers. "These are goods that people need, and higher prices are not helpful," CEO Corie Barry said.

Walmart also warned this week that tariffs could force it to raise prices, as did Footwear Distributors and Retailers of America.

Canadian Prime Minister Justin Trudeau, who talked with Trump after his call for tariffs, said they had a good conversation about how the countries can work together on the challenges they face.

"This is something that we can do, laying out the facts and moving forward in constructive ways. This is a relationship that we know takes a certain amount of working on and that's what we'll do," Trudeau said.

Trump's transition team wouldn't comment on the call.

Also Monday, Trump turned his ire to China, saying he has "had many talks with China about the massive amounts of drugs, in particular Fentanyl, being sent into the United States - But to no avail."

The Chinese Embassy in Washington cautioned on Monday that there will be losers on all sides if there is a trade war.

Trump's threats come as arrests for illegally crossing the border from Mexico have been falling. The most recent U.S. numbers for October show arrests remain near four-year lows. But arrests for illegally crossing the border from Canada have been rising over the past two years.

Much of America's fentanyl is smuggled from Mexico. Border seizures of the drug rose sharply under President Joe Biden.

The tariffs would also throw into doubt the reliability of the 2020 trade deal brokered in large part by Trump with Canada and Mexico, the USMCA, which replaced NAFTA and is up for review in 2026.

Trump transition team officials did not immediately respond to questions about what authority he would use, what he would need to see to prevent the tariffs from being implemented and how they would impact prices in the U.S.

Mexico's Foreign Relations Department and Economy Department also had no immediate reaction to Trump's statements.
