While he claims the tariffs will hurt foreign exporters, Americans will feel the pain too, as the extra costs will likely lead to higher prices on many products.

This move also could hit hard because Mexico and Canada are two of America’s biggest trade partners, making up 30% of U.S. imports. Retailers are trying to prepare by stocking up on goods or moving production elsewhere, but that won’t work for everything, and consumers will probably end up paying more.

Here’s where it’ll hurt the most:

• Cars and car parts: Mexico and Canada are major suppliers for the auto industry. With a 25% tariff, production costs will skyrocket, and manufacturers won’t easily be able to shift operations elsewhere.
• Gas: The U.S. buys a lot of oil and gas from Canada. A tariff could add up to 75 cents per gallon at the pump, especially in areas like the Midwest and Great Lakes.
• Food and drinks: Mexico is a big supplier of fresh fruits, vegetables, and alcohol. Prices on avocados, tequila, beer, and more could rise as retailers pass on the higher costs to shoppers.

In short, these tariffs might sound like a move against other countries, but they’ll likely make life more expensive for everyday Americans.
